View动画切换

activity切换直接通过overridePendingTransition()方法，直接输入动画资源就可以实现。

view之间的切换需要设置setInAnimation和setOutAnimation，需要编码实现

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()之前                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()之前                viewFlipper.setOutAnimation(anim_out_right2left);                viewFlipper.showPrevious(); // 切换到上一页            }            break;        case MotionEvent.ACTION_MOVE:            break;        }        return super.onTouchEvent(event);    } }
