圖片的淡入淡出效果實現

還算簡單，先發個圖看看效果。

主文件：

import android.app.Activity; import android.os.Bundle; import android.view.animation.AnimationUtils; import android.widget.ViewFlipper; public class TextAnimationActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ViewFlipper viewFilpper = (ViewFlipper) findViewById(R.id.flipper); viewFilpper.setInAnimation(AnimationUtils.loadAnimation(this,R.anim.push_in)); viewFilpper.setOutAnimation(AnimationUtils.loadAnimation(this, R.anim.push_out)); viewFilpper.startFlipping(); } }anim文件：

push_in.xml

<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"> <translate android:fromYDelta="100" android:toYDelta="0" android:duration="3000"/> <alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="3000" /> </set>
push_out.xml

<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"> <translate android:fromYDelta="0" android:toYDelta="-100" android:duration="500"/> <alpha android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="500" /> </set>
OK!
