Android 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);
}
}
布局文件：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<Button

android:layout_width="wrap_content"
android:layout_height="wrap_content"

上述用到的动画案例：
一 从大到小
1. zoomin.xml
