Activity切换和View切换动画

activity切换直接经过overridePendingTransition()方法，直接输入动画资源就能够实现。

view之间的切换须要设置setInAnimation和setOutAnimation，须要编码实现。

package com.zskx;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.ViewFlipper;

public class AnimationActivity extends Activity {
	ViewFlipper viewFlipper;
	
	Animation anim_in_left2right ; //从左到右进入动画
	Animation anim_out_left2right ; //从左到右出去动画
	Animation anim_in_right2left ; //从右到左进入动画
	Animation anim_out_right2left ; //从右到左出去动画
	
	int windowWidth;
	@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.first_activity);
        viewFlipper = (ViewFlipper) findViewById(R.id.viewFlipper);
        windowWidth =  getWindowManager().getDefaultDisplay().getWidth(); //屏幕宽度
       
        setAnimation(); //加载动画资源
    }
	private void setAnimation() {
		anim_in_left2right = AnimationUtils.loadAnimation(this, R.anim.in_left2right);
		anim_out_left2right = AnimationUtils.loadAnimation(this, R.anim.out_left2right);
		anim_in_right2left = AnimationUtils.loadAnimation(this, R.anim.in_right2left);
		anim_out_right2left = AnimationUtils.loadAnimation(this, R.anim.out_right2left);
	}
	/**
	 * 启动第二个activity
	 * @param v
	 */
    public void startSecond(View v){
    	Intent intent = new Intent(this, SecondActivity.class);
    	startActivity(intent);
    	AnimationActivity.this.overridePendingTransition(R.anim.activity_in,
    			R.anim.activity_out);//切换activity的动画，直接输入动画R资源
    }
    
    float lastX;
    float curX;
	@Override
	public boolean onTouchEvent(MotionEvent event) {
		switch (event.getAction()) {
		case MotionEvent.ACTION_DOWN:
			lastX =  event.getX();
			break;
		case MotionEvent.ACTION_UP:
			curX =  event.getX();
			if(curX - lastX > windowWidth * 0.75){ //拉动超过屏幕3/4, 从左到右切换page。
				viewFlipper.setInAnimation(anim_in_left2right); //设置动画必须在showNext()以前
				viewFlipper.setOutAnimation(anim_out_left2right);
				viewFlipper.showNext(); // 切换到下一页
			}else if(lastX - curX > windowWidth * 0.75){ //拉动超过屏幕3/4，从右到左切换page
				viewFlipper.setInAnimation(anim_in_right2left); //设置动画必须在showPrevious()以前
				viewFlipper.setOutAnimation(anim_out_right2left);
				viewFlipper.showPrevious(); // 切换到上一页
			}
			break;
		case MotionEvent.ACTION_MOVE:
			break;
		}
		
		return super.onTouchEvent(event);
	}
 }

淡入淡出动画的xml： 

in

<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false">
	<alpha
	    android:fromAlpha="0"
	    android:toAlpha="1.0"
	    android:duration="3000"
	    />
</set>

out

<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false">
	<alpha
	    android:fromAlpha="1.0"
	    android:toAlpha="0"
	    android:duration="3000"
	    />
</set>

 左右互换动画的xml：

in：

<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false">
	<translate 
	    android:fromXDelta="-100%p" 
	    android:toXDelta="0"
	    android:duration="3000"
	    />
</set>

<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false">
	<translate 
	    android:fromXDelta="100%p" <!--窗口宽度-->
	    android:toXDelta="0"
	    android:duration="3000"
	    />
</set>

out

<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false">
	<translate 
	    android:fromXDelta="0"
	    android:toXDelta="100%p"
	    android:duration="3000"
	    />
</set>

<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false">
	<translate 
	    android:fromXDelta="0"
	    android:toXDelta="-100%p"
	    android:duration="3000"
