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>
