Example of Android implementing cyclic translation animation

The implementation USES 1 background image as a loop from left to right translation animation.

1. Implement two animation xml files, one starting at -100%p and one at 0%p. Set the repeat property to loop and repeat.

<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/accelerate_interpolator">

    <translate android:fromXDelta="0%p" android:toXDelta="100%p"

        android:repeatMode="restart"

        android:interpolator="@android:anim/linear_interpolator"

        android:repeatCount="infinite"

        android:duration="30000" />

</set>

<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/accelerate_interpolator">

    <translate android:fromXDelta="-100%p" android:toXDelta="0%p"

        android:repeatMode="restart"

        android:interpolator="@android:anim/linear_interpolator"

        android:repeatCount="infinite"

        android:duration="30000" />

</set>

2. Put two one-sample view in the layout of view as the background, and the animation of view corresponds to the two animation above respectively.

        <ImageView

             android:id="@+id/animation_top_left"

             android:layout_width="wrap_content"

             android:layout_height="wrap_content"

             android:contentDescription="@string/logo"

             android:src="@drawable/home_animation_bg" /> 

         <ImageView

             android:id="@+id/animation_top_right"  android:layout_width="wrap_content"

             android:layout_height="wrap_content"

             android:contentDescription="@string/logo"

             android:src="@drawable/home_animation_bg" />

Animation anim = AnimationUtils.loadAnimation(mContext, R.anim.home_animation);

ImageView animationTopRightView = (ImageView)this.findViewById(R.id.animation_top_right);

animationTopRightView.startAnimation(anim);

Animation anim2 = AnimationUtils.loadAnimation(mContext, R.anim.home_animation2);

ImageView animationTopLeftView = (ImageView)this.findViewById(R.id.animation_top_left); 

animationTopLeftView.startAnimation(anim2);
