ACtivity实现欢迎界面并添加动画切换效果

先看效果：





中间切换动画没来得及截图，凑合着看吧。

主要是java代码的实现：

Welcom.java

package kehr.activity.welcome;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.view.Window;
import android.view.WindowManager;

public class Welcome extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//全屏
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
//无标题
requestWindowFeature(Window.FEATURE_NO_TITLE);

setContentView(R.layout.welcome_layout);
Handler handler = new Handler();
//使用pastDelayed方法延时
handler.postDelayed(new Runnable() {

@Override
public void run() {
Intent intent = new Intent(Welcome.this, Start.class);
startActivityForResult(intent, 11);

//添加界面切换效果
int version = Integer.valueOf(android.os.Build.VERSION.SDK_INT);
//只有android2.0（版本号为5）以上的版本支持
if(version  >= 5) {
//自定义动画效果
//overridePendingTransition(R.layout.zoom_enter, R.layout.zoom_exit);
//系统动画效果
//				   overridePendingTransition(android.R.anim.fade_in,android.R.anim.fade_out);
overridePendingTransition(android.R.anim.slide_in_left,android.R.anim.slide_out_right);
}
//结束欢迎界面
Welcome.this.finish();

}
}, 3000);
}

}

Start.java

package kehr.activity.welcome;

import android.app.Activity;
import android.os.Bundle;

public class Start extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.start_layout);
//这里面就可以做其它的设置了，这里只是绑定了一个布局文件
}

}

两个自定义动画文件：

zoom_enter.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/decelerate_interpolator" >

<scale
android:duration="@android:integer/config_mediumAnimTime"
android:fromXScale="2.0"
android:fromYScale="2.0"
android:pivotX="50%p"
android:pivotY="50%p"
android:toXScale="1.0"
android:toYScale="1.0" />

</set>

zoom_exit.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/decelerate_interpolator"
android:zAdjustment="top" >

<scale
android:duration="@android:integer/config_mediumAnimTime"
android:fromXScale="1.0"
android:fromYScale="1.0"
android:pivotX="50%p"
android:pivotY="50%p"
android:toXScale=".5"
android:toYScale=".5" />

<alpha
android:duration="@android:integer/config_mediumAnimTime"
android:fromAlpha="1.0"
android:toAlpha="0" />

</set>
