一 ,、利用View自身的setAnimation來實現(xiàn)動畫（TextView、imageView,、ListView等都可以實現(xiàn))

java代碼：

[java] view plain copy

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代碼：

[html] view plain copy

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas./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>

關(guān)鍵代碼：

[html] view plain copy

txtview.setAnimation(AnimationUtils.loadAnimation(this, R.anim.push_left_in));

二,、ViewFlipper實現(xiàn)左右滑動效果轉(zhuǎn)載自（http://www.cnblogs.com/hanyonglu/archive/2012/02/13/2349827.html）

java代碼：

[html] view plain copy

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;

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);
flipper.addView(addImageView(R.drawable.one));
flipper.addView(addImageView(R.drawable.two));

// TODO Auto-generated method stub
return this.detector.onTouchEvent(event);

@Override

// 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;
}
}

為了使其滑動時有一定的特效，我們需要加入Animation效果,，說到Animation,，我們先看下如何在Android中實現(xiàn)自定義Animation。自定義的Animation是以XML格式定義的,，定義好的XML文件存放在res/anim中,。

　　一般的Animation有以下四種類型：
　　1. Alpha：漸變透明度動畫效果
　　2. Scale：漸變尺寸伸縮動畫效果
　　3. Translate：畫面轉(zhuǎn)換位置移動動畫效果
　　4. Rotate：畫面轉(zhuǎn)換位置移動動畫效果
