NPE on Android 2.3.3 about android-switch-backport HOT 11 CLOSED

My Bad for ActionBarSherlock I was overriding the default theme. Adding shareStyle to Sherlock theme.

from android-switch-backport.

I'm getting the same exception but not sure what Hemanshu did exactly to fix it.

My Activity uses

android:theme="@style/Theme.NoAudibleSelection"

and this theme is defined as

<style name="Theme.NoAudibleSelection" parent="android:Theme.NoTitleBar.Fullscreen">
<item name="android:soundEffectsEnabled">false</item>
<item name="switchStyle">@style/Widget.Holo.CompoundButton.Switch</item>
</style>

from android-switch-backport.

Try parent="@android:style/Theme.NoTitleBar.Fullscreen"

Thanks for your quick reply. It started working all by itself without any changes when I restarted Eclipse. Was having a "Missing styles. Is the correct theme chosen for this layout?" error in the layout design GUI and now it seems to work OK. I'll comment if I figure out the real reason behind it.

I'm having this same issue but in a blank app. Target version is 4.0.3 while min version is 2.3.3. Same exact error.

Sorry, I wan't able to find out the exact reason, I just used Clean Project in Eclipse and also restarted it and it stopped crashing with no code modifications.

Damn, it has to be another thing... I have cleaned up all this stuff and no luck. Gonna create a new project now and see if it's working.
EDIT: New project and not working. Here is the detail of what I'm doing:

• My activity layout (relative layout):

<org.jraf.android.backport.switchwidget.Switch
    android:id="@+id/switch2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

Really hope I'm missing something.

To all of you who cannot get this to work:
Are you using Eclipse, or another IDE?

from android-switch-backport.

Eclipse. Although I finally solved the problem, have been quite busy lately... sorry for not posting back.

The problem was that for some reason, the style was not found, causing the switch to crush on load. Here I drop you a couple of lines:

In the constructor

public Switch(Context context, AttributeSet attrs, int defStyle) {

I changed the line

final TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.Switch, defStyle, 0);

to

final TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.Switch, defStyle, R.style.Widget_Holo_CompoundButton_Switch);

To force it getting the style. If I didn't do this the switch styles were'nt found in the typedarray and a nullpointer was thrown.

Hope this helps.

Just as a follow up, make sure you are actually using the theme that you declare! To do that you must reference it in your AndroidManifest.xml. I just updated the readme file to clarify this. Hope this helps.

I'm having the same issue. I'm using Switch in a custom Dialog. Solution from cbmarc solved it for me.
