android使用activity切换动画效果

先创建2个activity

配置对应的布局文件和清单文件

我使用了2个透明度动画效果，放在res下的anim文件夹下

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"    android:shareInterpolator="false"><alpha        android:fromAlpha="0"        android:toAlpha="1"        android:duration="5000"     /></set>

和

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"    android:shareInterpolator="false"><alpha        android:fromAlpha="1.0"        android:toAlpha="0"        android:duration="5000"     /></set>

主activity

package cn.wonders.animation;import android.support.v7.app.ActionBarActivity;import android.view.View;import android.content.Intent;import android.os.Bundle;public class MainActivity extends ActionBarActivity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);}public void openActivity(View v) {Intent intent = new Intent(this, OtherActivity.class);startActivity(intent);//activity切换动画效果overridePendingTransition(R.anim.enteralpha, R.anim.outalpha);}}

布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" >    <TextView         android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:text="@string/first_activity"        />        <Button         android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:text="@string/open"    android:onClick="openActivity"        /></LinearLayout>

另一个activity

package cn.wonders.animation;import android.support.v7.app.ActionBarActivity;import android.os.Bundle;public class OtherActivity extends ActionBarActivity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.other);}}

布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" >    <TextView         android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:text="@string/second_activity"        /></LinearLayout>
