A TextView that changes its content automatically every few seconds

A demo app is available on Google Play:

FadingTextView is available on JitPack

Step 1. Add the JitPack repository to your root build.gradle

allprojects {
  repositories {
     ...
     maven { url 'https://jitpack.io' }
  }
}

Step 2. Add the dependency

dependencies {
    implementation 'com.github.rosenpin:fading-text-view:3.0'
}

First, you need to create a string-array in your values folder like so:

<string-array name="examples">
     <item>Hello</item>
     <item>Fading TextView</item>
</string-array>

Then in your layout

<com.tomer.fadingtextview.FadingTextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:texts="@array/examples" />

You can set the amount of time that each text is visible by using the timeout attribute and by specifying the length of time in milliseconds. Like so:

app:timeout="500"

<com.tomer.fadingtextview.FadingTextView
            android:id="@+id/fadingTextView"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:timeout="500"
            app:texts="@array/examples" />

To set the text dynamically, you can use

String[] texts = {"text1","text2","text3"};
FadingTextView FTV = (FadingTextView) findViewById(R.id.fadingTextView);
FTV.setTexts(texts); //You can use an array resource or a string array as the parameter

To set the timeout between text changes you can use:

//For text change once every hour
FTV.setTimeout(60, MINUTES);

//For text change once every half a minute
FTV.setTimeout(0.5, MINUTES);

//For text change every 10 seconds
FTV.setTimeout(10, SECONDS);

//For text change every 500 milliseconds (0.5 seconds)
FTV.setTimeout(500, MILLISECONDS);

You can randomize the order of the strings using the shuffle method
Note: you will need to run the shuffle method after each time you update the view
Example:

FTV.setTexts(texts);
FTV.shuffle();
