一 、 利用View自身的setAnimation来实现动画（TextView、ImageView、ListView等都可以实现)
java代码：public void UpdateViewContent(){ TextView txtview = (TextView)findViewById(R.id.content_view); txtview.setText(MyGetNextText()); txtview.setAnimation(AnimationUtils.loadAnimation(this, R.anim.push_left_in)); }
Xml代码：
<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"> <translate android:fromXDelta="0" android:toXDelta="100%" android:duration="300"/> <alpha android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="300" /> </set>
关键代码：txtview.setAnimation(AnimationUtils.loadAnimation(this, R.anim.push_left_in));
二、ViewFlipper实现左右滑动效果转载自（http://www.cnblogs.com/hanyonglu/archive/2012/02/13/2349827.html）
java代码：package com.android.flip; import android.app.Activity; import android.os.Bundle; import android.view.GestureDetector; import android.view.MotionEvent; import android.view.View; import android.view.GestureDetector.OnGestureListener; import android.view.animation.AnimationUtils; import android.widget.ImageView; import android.widget.ViewFlipper; /** * Android实现左右滑动效果 * @Description: Android实现左右滑动效果 * @File: MainActivity.java * @Package com.android.flip * @Author Hanyonglu * @Date 2012-02-12 上午10:44:04 * @Version V1.0 */ public class MainActivity extends Activity implements OnGestureListener { private ViewFlipper flipper; private GestureDetector detector; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); detector = new GestureDetector(this); flipper = (ViewFlipper) this.findViewById(R.id.ViewFlipper1); //添加图片 flipper.addView(addImageView(R.drawable.one)); flipper.addView(addImageView(R.drawable.two)); flipper.addView(addImageView(R.drawable.three)); flipper.addView(addImageView(R.drawable.four)); flipper.addView(addImageView(R.drawable.five)); //添加layout //flipper.addView(addView(R.layout.layout1)); } private View addImageView(int id) { ImageView iv = new ImageView(this); iv.setImageResource(id); return iv; } @Override public boolean onTouchEvent(MotionEvent event) { // TODO Auto-generated method stub return this.detector.onTouchEvent(event); } @Override public boolean onDown(MotionEvent e) { // TODO Auto-generated method stub return false; } @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { if (e1.getX() - e2.getX() > 120) { this.flipper.setInAnimation(AnimationUtils.loadAnimation(this, R.anim.push_left_in)); this.flipper.setOutAnimation(AnimationUtils.loadAnimation(this, R.anim.push_left_out)); this.flipper.showNext(); return true; } else if (e1.getX() - e2.getX() < -120) { this.flipper.setInAnimation(AnimationUtils.loadAnimation(this, R.anim.push_right_in)); this.flipper.setOutAnimation(AnimationUtils.loadAnimation(this, R.anim.push_right_out)); this.flipper.showPrevious(); return true; } return false; } @Override public void onLongPress(MotionEvent e) { // TODO Auto-generated method stub } @Override public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) { // TODO Auto-generated method stub return false; } @Override public void onShowPress(MotionEvent e) { // TODO Auto-generated method stub } @Override public boolean onSingleTapUp(MotionEvent e) { // TODO Auto-generated method stub return false; } } xml代码： <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <ViewFlipper android:id="@+id/ViewFlipper1" android:layout_width="fill_parent" android:layout_height="fill_parent"> </ViewFlipper> </LinearLayout>
为了使其滑动时有一定的特效，我们需要加入Animation效果，说到Animation，我们先看下如何在Android中实现自定义Animation。自定义的Animation是以XML格式定义的，定义好的XML文件存放在res/anim中。
一般的Animation有以下四种类型：
1. Alpha：渐变透明度动画效果
2. Scale：渐变尺寸伸缩动画效果
3. Translate：画面转换位置移动动画效果
4. Rotate：画面转换位置移动动画效果
push_left_in.xml文件中代码：
<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"> <translate android:fromXDelta="100%p" android:toXDelta="0" android:duration="500" /> <alpha android:fromAlpha="0.1" android:toAlpha="1.0" android:duration="500" /> </set>
push_left_out.xml文件中代码：
<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"> <translate android:fromXDelta="0" android:toXDelta="-100%p" android:duration="500" /> <alpha android:fromAlpha="1.0" android:toAlpha="0.1" android:duration="500" /> </set>
push_right_in.xml文件中代码：
<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"> <translate android:fromXDelta="-100%p" android:toXDelta="0" android:duration="500" /> <alpha android:fromAlpha="0.1" android:toAlpha="1.0" android:duration="500" /> </set>
push_right_out.xml文件中代码：
<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"> <translate android:fromXDelta="0" android:toXDelta="100%p" android:duration="500" /> <alpha android:fromAlpha="1.0" android:toAlpha="0.1" android:duration="500" /> </set>
