}

Enable any View extending TextView in code:

AutofitHelper.create(textView);

Enable any View extending TextView in XML:

<me.grantland.widget.AutofitLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    >
    <Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:singleLine="true"
        />
</me.grantland.widget.AutofitLayout>

Use the built in Widget in code or XML:

<RootElement
    xmlns:autofit="http://schemas.android.com/apk/res-auto"
    ...

<me.grantland.widget.AutofitTextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"

android-autofittextview's Issues

How to set minTextSize?

I saw that for release 0.2.1, there is a fix for:
Fix minTextSize set from attrs

How can I use this setting if i am importing with maven?

using with textclock

Hi! i'm new with Android development and i tried to use your code with TextClock. It doesn't work.
I tried also to extend Textclock cloning your AutofitTextView with no success... can you help me?

<me.grantland.widget.AutofitLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    >
    <TextClock
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:singleLine="true"
        />
</me.grantland.widget.AutofitLayout>

<com.example.valenti.healthwatch.AutofitTextClock
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/orologio"
        android:textSize="50sp"
        autofit:minTextSize="8sp"
        android:gravity="center"
        android:singleLine="true"
        android:layout_centerInParent="true"/>

Text height is not considered

Text height is not measured and considered. So, when a single line short text (like HELLO) with big textview width and small textview height is used, the size will be too big for the height.

The following method can be used to determine the height.

private int getTextHeight(CharSequence text, TextPaint paint, int targetWidth, float textSize) {
    TextPaint paintCopy = new TextPaint(paint);
    paintCopy.setTextSize(textSize);
    StaticLayout layout = new StaticLayout(text, paintCopy, (int)targetWidth, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0.0f, true);
    return layout.getHeight();
}

At the end of "void refitText()" method, using the following code would solve the problem:

        while(getTextHeight(text, mPaint, targetWidth, size) > targetHeight) {
            size--;
        }
       super.setTextSize(TypedValue.COMPLEX_UNIT_PX, size);

Issue with using inside listview

Hey,

I have used this library.

Its working fine if i am using in any view.

But when i integrate this library with list view. It changing text size randomly.

Let me add my code here, I have added this code inside my list item.

                         <me.grantland.widget.AutofitTextView
                        android:id="@+id/tvAudience"
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:gravity="center"
                        android:layout_gravity="center_vertical"
                        android:text="Publifhbgdfgdfgfggfgc"
                        android:maxWidth="@dimen/max_width_targetaudience"
                        android:singleLine="true"
                        android:textColor="@color/blue_text" />

Can anyone help me to resolve this issue?

Thanks

Bug: text get truncated even though there is a lot of space left, and characters can go to next line

On some cases, the letter of one word goes to the next line.

Here's a sample case:

    <me.grantland.widget.AutofitTextView
        android:id="@+id/output_autofit"
        android:layout_width="286dp"
        android:layout_height="305dp"
        android:maxLines="3"
        android:text="content text sample"         />

mAutofitOutput = (AutofitTextView) findViewById(R.id.output_autofit);
mAutofitOutput.setMaxTextSize(1000);

BTW, there is no "maxTextSize" attribute, so I had to do it via code instead.

The result (modified the sample) :

Not only that, but for the same case, when increasing the width of the textView, the text itself gets truncated. Here's what happens when I set the width to match_parent :

When android:gravity="right", text disappered

failed to find error!

i get this error when when want add it to android studio:

Error:Failed to find: me.grantland:autofittextview:0.2.+

Add a group name attribute to syncronize sizes of multiple textviews

I would suggest you add a group name attribute so that multiple textviews can synchronize their sizes. The smallest one will set the size of the rest.

There is bug in Android Honeycomb and Ice Cream Sandwich

There is an important fixed bug affecting Android 3.1 - 4.04 causing all AutoResizingTextView widgets not to work. Please read: http://stackoverflow.com/a/21851157/2075875

Is there a way to unlink a TextView with this library? I have to find the smallest textSize for a particular TextView and store it, and then set a very new textSize to that TextView�.
However, the TextView's text gets resized, no matter the new textSize I've set. I have also tried to reinitialize the TextView via the findViewById method.

I am using regular TextView in my xml, and then AutoFitHelper.create(myTextView) in code.

There must be a workaround here.

textAllCaps support

When using textAllCaps parameter the size of the text is not correctly calculated.

StackOverflowError in getTextSize() on line 306

While trying with various Japanese strings, I've encountered a StackOverflowError:

This seems to be related to encoding....

Textsize too large when adding drawable to TextView

Below is my code in XML that adds a drawable icon to the textview. The text resizes but is always slightly too large for the button. I think this class does not consider the offset from the drawable:

   <me.grantland.widget.AutofitTextView
        android:layout_width="150dp"
        android:layout_height="35dp"
        android:text="VEHICLE"
        android:id="@+id/order_button_vehicle"
        android:textColor="@color/honk_order_help_button"
        android:background="@drawable/order_help_button"
        android:textSize="14sp"
        android:drawableLeft="@drawable/icon_car"
        android:drawableStart="@drawable/icon_car"
        android:drawablePadding="5dp"
        android:paddingLeft="10dp"
        android:paddingBottom="10dp"
        android:paddingRight="10dp"
        android:layout_alignBottom="@+id/order_button_payment"
        android:layout_toRightOf="@+id/centerView"
        android:layout_toEndOf="@+id/centerView"
        android:layout_marginLeft="10dp"
        android:layout_marginStart="10dp"
        android:singleLine="true"
        autofit:minTextSize="6sp"
     />

SetTextSize on Runtime?

i found that change the AutoFitTextView font size, style on Runtime exist issue.
Thanks

Log TAG > 23 Characters

AutofitTextView.java defines the TAG constant as "me.grantland.widget.AutoFitTextView", which is greater than the 23 character limit specified in the [Android Docs](http://developer.android.com/reference/android/util/Log.html#isLoggable%28java.lang.String, int%29).

Lower minSdkVersion

Hello.
Is there a chance, that you will reduce minSdkVersion?
To 10 for example.
Regards.

doesn't work with android:layout_width="wrap_content"

Currently AutofitTextView doesn't work correctly when using android:layout_width="wrap_content". The view will only decrease in size.

Using android:layout_width="match_parent" is not an option, because in need to have a second view next to it which moves when the AutofitTextView gets bigger.

I think I have found a solution and will sent a PR

S4 - AutoFit

I´m creating a list view with a lot of fields and with S4 the fiels don´t make the autofit. I think that the problem is the little space available.

In S4

What should appear

The code

<me.grantland.widget.AutofitTextView
            android:id="@+id/data_entrada"
            android:layout_width="0dip"
            android:layout_height="wrap_content"
            android:layout_weight="16"

            android:singleLine="true"/> <!-- obrigatório -->

Do you have any quick fix?

Thanks

Better support for subclassing AutoFitTextview

Here are a couple of things that would make subclassing AutoFitTextview more useful:

Provide a way to get the current actual text size.

You overrode getTextSize like this:

   public float getTextSize() {
        return mMaxTextSize;
    }

May you could do this instead:

   public float getMaxTextSize() {
        return mMaxTextSize;
    }

   public float getTextSize() {
        return mMaxTextSize;
    }
   public float getCurrentTextSize() {
        return super.getTextSize();
    }

Also, provide a way for subclasses to get notified when the text size is updated:

 public void onTextSizeWasAutoFitted(int size){}

I think there is a bug in AutofitHelper.java

I'm not for sure but I think the create() method in AutofitHelper.java, this line helper.setMinTextSize(minTextSize).setPrecision(precision); is not right. You should call setRawMinTextSize() rather than call setMinTextSize(). And I have reasons for this: I notice that getDimensionPixelSize() method returns size in pixel not in sp or dp, as we go deep inside, we can find that this method already converts sp to px! if you call setMinTextSize() method, you will convert it again! So I think this line should be changed to something like helper.setRawMinTextSize(minTextSize).setPrecision(precision); Am I right? Thank you!

Use the CharSequence ( don't call to toString )

Right now, you are calling

        String text = getText().toString();

This makes AutoFitTextView not render Spannables correctly.

Instead, just do:

    CharSequence text = getText();

You can just use the CharSequence everywhere, e.g.:

  mPaint.measureText(text, 0, text.length())

Also, the StaticLayout constructor takes a CharSequence

The min default text size isn't set correctly

Expected Behavior:
When you retrofit existing TextViews and change them to AutoFitTextViews in xml, they should resize correctly as more text is added to field.

Observed Behavior:
TextViews changed to AutoFitTextViews Don't resize correctly to the Default min size (8sp)

Reproducible Test:
In the project sample, remove the following line in main.xml
autofit:minTextSize="8sp"
see screenshot below

Reason:
AutoFitHelper.java:66 int minTextSize = (int) helper.getMinTextSize();
AutoFitHelper.java:75 minTextSize = ta.getDimensionPixelSize(R.styleable.AutofitTextView_minTextSize, minTextSize);

both of the returned sizes above are in Pixels...

AutoFitHelper.java:80 helper.setMinTextSize(minTextSize)

This method signature applies SP as no TypedUnit is specified. So, taking my density into account (xxhdpi) the density factor is 3. The min was/should be 24px but then the above method changed it to 72px

Proposed Solution:
change AutoFitHelper.java:80 to
helper.setRawMinTextSize(minTextSize);
helper.setPrecision(precision);

Using AutofitTextView in widget

I'm using AutofitTextView in a LinearLayout (A):

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="60dp"
    android:layout_height="match_parent"
    android:padding="0dp">

    <me.grantland.widget.AutofitTextView
        android:id="@+id/label"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:singleLine="true"
        />

<!-- old code
    <TextView
        android:id="@+id/label"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:singleLine="true"
        /> -->
</LinearLayout>

From my AppWidgetProvider, I'm dynamically adding some linear layout A.

On the device the Widget is not loading, an error is displayed: "Problem loading widget", but I don't see any error on logcat.

Text in one line only

Hello.
What I want to achieve is exactly what is shown on animation.
But, if I set android:singleLine="true" text never expands to second line.
If single line is not set, resizing don't work.

Even if I run your demo, text is always in one line.

Use library with Eclipse

Hi could you help me and tell me how i have to do to add you library in my Eclipse project ?

does not work in android-L support library

text does not auto-fit when using support library com.android.support:appcompat-v7:21.0.0

am i the only one with this issue?

Textview re-sizing issue

I am attempting to use your textview with it's height set as wrap-content within a fragment.

However, when the text is set BEFORE the text view is drawn (so in the fragment's onCreateView), the text gets resized, but the size of the TextView itself does not.

This ends up getting remedied the next time a sibling view is updated; resulting in a jarring UI experience as the textview all of a sudden shrinks to the correct size (moving the sibling views as well).

If the text is resized once the view is drawn, it works as intended. Have you experienced this issue before, and if so, do you have a workaround?

Add height/maxHeight support.

Probably will utilize StaticLayout.

Auto fit doesn't work with extra line space

<me.grantland.widget.AutofitTextView
    android:id="@+id/tv_description"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="0.4"
    android:lineSpacingExtra="6sp"
    android:textColor="@color/black"
    android:textSize="12sp"
    autofit:minTextSize="8sp"/>

When using lineSpacingExtra, resizing doesn't work.

Please create idea

HI!

Add:
app:minFontSize="12sp"

Error:
When set, for example, android: maxLines = " 3 " the text of the two words is broken down into all 3 lines instead of 2.

TextView line height in fragments is changing on page swapping

Hello!
I have a problem with the following code

        textView = new TextView(getContext());
        textView .setLayoutParams(new LinearLayout.LayoutParams(
                LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT, 1f));
        // ...
        AutofitHelper.create(textView)
                .setMinTextSize(TypedValue.COMPLEX_UNIT_SP, 14);

within Fragments (FragmentStatePagerAdapter).

On each fragment there are person names (textView) getting autofitted using your class. That works great until i reach another fragment where the height of the textview is getting changed.
When i scroll back to the other fragment, the text size stays the same like before but the height of the textview is increased to the higher one.
Looks like all textviews in the fragment will be normalized to the same height or even to the same line height...

Is there a way around that behavior?

Or is it a problem of the Fragment.SavedState instead of AutofitHelper?

I tried to requestLayout() at onPageSelected(int). That works at all but i would need to call requestLayout also on every getViewPager().setCurrentItem() because it is not calling onPageSelected. Maybe theres an easier/better way?

Thank you!

Best Regards,
Juergen

Autofit for maxLines="n" doesn't work.

Unintended text wrap

I have a text view that needs to have a fixed width, but can have a max of two lines. What I would like is if the text is a single word that it be autofit to the first line, but if the text is multiple words, it should use both lines. The behavior that I get now is that the single word wraps onto the second line instead of autofitting.

In the following example, my intention is to have the string ABCDEFGH autofit a single line, but since maxLines is 2, the autofit allows it to wrap to the next line, so H ends up on the second line by itself.

<me.grantland.widget.AutofitTextView
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:text="ABCDEFGH"
        android:textSize="20dp"
        android:maxLines="2"/>

Can a mechanism be added to allow the autofit logic to look to see how many words are in the string and attempt to treat single word strings as a single line?

wrong size on Nexus 5

I used AutofitTextView with xml and the text was nearly two times larger on a Nexus 5 (API21) than on Nexus 7 (2013, API21) or Nexus 4 (API15). Using "AutofitHelper.create(textView);" with a normal TextView worked. Maybe there is a problem with xxhdpi devices?

crash at setcontentview

Autofittextview was working fine till i tried to implement something;
I deleted everything i made, the code is fully same the time it was working.

Please help

SpannableString bug

Hello,
I have a bug using your useful nice lib when I set a SpannableString to AutofitTextView : the text doesn't fit at all (it's really little compared to the possible max size). Is this a known problem and is it possible to fix it (I also tried with a TextView within a AutofitLayout but result is the same) ?
Thank you !

Use lower value of minSdkVersion?

Is it possible to use a lower value for minSdkVersion? Currently, AutofitTextView is the reason why my app is forced to use minSdkVersion=14 and it would be really great to support version 10.

AutofitTextView doesn't work properly with TextSwitcher

If I use AutofitTextView inside a TextSwitcher the text won't be resized.

CustomViewFactory.java:

...
@Override
public View makeView() {
    AutofitTextView textView = (AutofitTextView) mActivity.getLayoutInflater().inflate(R.layout.text_view_output, mRoot, false);
    return textView;
}
...

text_view_output.xml:

<?xml version="1.0" encoding="utf-8"?>
<me.grantland.widget.AutofitTextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:lines="1"
    android:gravity="center">
</me.grantland.widget.AutofitTextView>

activity_main.xml

...
<RelativeLayout
    android:id="@+id/relativeLayoutContent"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:gravity="end">

    ...

    <TextSwitcher
        android:id="@+id/textSwitcherOutput"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

</RelativeLayout>
...

no text displayed

hi i have tried your view but i don't get any text, the view stay empty ??

Request: adopt StrokedTextView - as you have solved the measurement issues

Hi,

Request that you integrate a reworked StrokedTextView into your app.

reference: https://android.googlesource.com/platform/packages/apps/Launcher2/+/android-4.2_r1/src/com/android/launcher2/StrokedTextView.java

The problem with StrokedTextView is that if you use a heavy stroke - say 12 - the TextView gets cropped on the right. It just doesn't expand the canvas properly to account for the addition of the outline.

I've looked at all available variations of "How to outline a TextView" I could find - and they all suffer the problem of not expanding the canvas width calculations.

Thank you.

Add stroke for text content

How can I add a stroke for content of text?
I tried to override onDraw with Paint.Style.STROKE but it's too difficult to locale position of stroke text.
Anyone can help me? thanks a lot!

AutofitTextView with Kerning?

Hi,

Firstly I thank you for this library. It works for me well. I use autofitTextView to resize my text widgets. In Addition to I want to add kerning into your library. I have created a custom view extending your autofitTextView class, and I have tried to add kerning code into my custom view class. My code didn't work as I want. I am giving you my code, maybe you can help me.

public class KerningSizeAdjustingTextView extends AutofitTextView
{
private float spacing = Spacing.NORMAL;

// Default constructor override
public KerningSizeAdjustingTextView(Context context) {
    this(context, null);
}

// Default constructor when inflating from XML file
public KerningSizeAdjustingTextView(Context context, AttributeSet attrs) {
    this(context, attrs, 0);
}

// Default constructor override
public KerningSizeAdjustingTextView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
}

public float getSpacing() {
    return this.spacing;
}

public void setSpacing(float spacing) {
    this.spacing = spacing;
    applySpacing();
}

private void applySpacing() {
    if (this == null || this.getText() == null) return;
    StringBuilder builder = new StringBuilder();
    for(int i = 0; i < getText().length(); i++) {
        builder.append(getText().charAt( i ));
        if(i+1 < getText().length()) {
            builder.append("\u00A0");
        }
    }
    SpannableString finalText = new SpannableString(builder.toString());
    if(builder.toString().length() > 1) {
        for(int i = 1; i < builder.toString().length(); i+=2) {
            finalText.setSpan(new ScaleXSpan((spacing+1)/10), i, i+1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
        }
    }
    super.setText( finalText, BufferType.SPANNABLE );
}

public class Spacing {
    public final static float NORMAL = 0;
}

}

Actually I just want two properties for my text view . Rightly, TextView will be resized and kerning.
