Android(安卓)Activity切换动画案例

Activity的切换动画指的是从一个activity跳转到另外一个activity时的动画。它包括两个部分：
一部分是第一个activity退出时的动画；另外一部分时第二个activity进入时的动画。
在Android的2.0版本之后，有了一个overridePendingTransition函数来帮我们实现这个动画

测试类：

ActivityAnimationTest.java

package com.example.android;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.widget.Button;public class ActivityAnimationTest extends Activity {    private int mAnimResoureIdEnter;    private int mAnimResoureIdExit;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_anim_main);        ((Button) findViewById(R.id.btn1)).setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                mAnimResoureIdEnter = R.anim.zoomin;                mAnimResoureIdExit = R.anim.zoomout;                finish();            }        });        ((Button) findViewById(R.id.btn2)).setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                mAnimResoureIdEnter = R.anim.slide_in_right;                mAnimResoureIdExit = R.anim.slide_out_right;                finish();            }        });        ((Button) findViewById(R.id.btn3)).setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                mAnimResoureIdEnter = R.anim.slide_in_left;                mAnimResoureIdExit = R.anim.slide_out_right;                finish();            }        });        ((Button) findViewById(R.id.btn4)).setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                mAnimResoureIdEnter = R.anim.fade_in;                mAnimResoureIdExit = R.anim.fade_out;                finish();            }        });    }    @Override    public void finish() {        super.finish();        overridePendingTransition(mAnimResoureIdEnter, mAnimResoureIdExit);    }}
