[Android] simple animation for UI switching, android Switching

1. Create an xml file for the displacement Animation

Enable animation in Activity

Use the AnimationUtils class to load animation resource files

Left_to_right.xml

<?xml version="1.0" encoding="utf-8"?><translate xmlns:android="http://schemas.android.com/apk/res/android"    android:fromXDelta="100%"    android:toXDelta="0"    android:duration="3000"    ></translate>

View child=new IndexView(this).getMemberView();child.startAnimation(AnimationUtils.loadAnimation(this, R.anim.left_to_right));

 

 

2. Fade-in and fade-out animation

Current fade-out interface and execution time

The Fade-In interface is in the waiting status during the fade-out process.

The second interface fades in and executes the time

After the first interface is executed, delete it.

FadeUtil.fadeOut(child, 2000);

FadeUtil.fadeIn(child, 2000,2000);
