AutoTextSwitcher

This is an Android project allowing to auto change text in specific period of time with your chosen animation.

Add dependency

• First add repository in your build.gradle file at project level:

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

Or with newest Gradle version (+7.2.0) do like this in settings.gradle file:

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

• And then add dependency to your project in the build.gradle file at app level:

implementation 'com.github.masoudsaraf:androidautotextswitcher:1.0.2'

How to use in XML

You can set textArray from XML or java code. In XML easiest way is add your text in strings resource and create a text array like this:

<resources>
    ....
    <string name="first_text">Show awesome first text</string>
    <string name="second_text">Show awesome second text</string>

    <string-array name="textArray">
        <item>@string/first_text</item>
        <item>@string/second_text</item>
    </string-array>
</resources>

And then use created textArray as follow:

<com.masoud.autotextswitcher.AutoTextSwitcher
    android:id="@+id/textSwitcher"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inAnimation="@anim/text_in_animation"
    android:outAnimation="@anim/text_out_animation" 
    app:textArray="@array/textArray"
    app:changeAnimationTime="3000" 
    app:autoStart="true"/>

You can use following properties:
android:inAnimation Set animation for show next text.
android:outAnimation Set animation for hide current text.
app:textArray Set array of string.
app:changeAnimationTime Set time in milliseconds.
app:autoStart Indicates auto start changing text or not

Complete work in java code

In your Activity class access to AutoTextSwitcher element with findViewById and then set factory to create a text view with your preferred properties:

public class MainActivity extends AppCompatActivity
{
    protected void onCreate(Bundle savedInstanceState)
    {
        ...
        AutoTextSwitcher textSwitcher = findViewById(R.id.textSwitcher);
        textSwitcher.setFactory(() ->
        {
            AppCompatTextView textView = new AppCompatTextView(MainActivity.this);
            // set custom text appearance
            textView.setTextAppearance(MainActivity.this, R.style.InfoTextAppearanceStyle);
            textView.setPadding(10, 10, 10, 10);
            textView.setShadowLayer(12, 0, -5.5f, Color.parseColor("#65FFFFFF"));
            return textView;
        });
    }
}
