下面是我总结的Android闪屏的经验，供大家参考，以下代码，可以直接粘贴，稍作修改就好

1.导入一张图片，我起名叫sp.png

2.在res/layout目录下创建splashy.xml加入如下代码：

<?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" >


    <ImageView
        android:id="@+id/img"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/sp" />


</LinearLayout>

3.创建一个名为SplashyDemo.java的类，加入如下代码：

package com.example.splashydemo;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.Window;
import android.view.WindowManager;

public class SplashyDemo extends Activity {
private long splashyTime = 3000;//闪屏停留时间
private boolean isStop =false;//闪屏暂停
private boolean isActivity = true;//是否跳过闪屏直接进入主Activity
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);// 隐藏标题
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);// 设置全屏

setContentView(R.layout.splashy);

Thread splashyThread = new Thread()
{
public void run()
{
try {
long ms = 0;
while(isActivity && ms <splashyTime)
{
sleep(100);
if(!isStop)
{
ms+=100;
}
Log.i("TAG",ms+"");
}

//加入此 会去配置文件AndroidManifest.xml找对应的com.google.app.splashy.CLEARSPLASH,有此标识的Activity是闪屏后切换的界面
startActivity(new Intent("com.google.app.splashy.CLEARSPLASH"));

} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
finally{
                   finish();
               }
}
};
splashyThread.start();
}
@Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
isStop = true;
}
@Override
protected void onRestart() {
// TODO Auto-generated method stub
super.onRestart();
isStop = false;
}
}

4.在AndroidManifest.xml文件中进行配置

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity

//这里是我的主Activity的路径
            android:name="com.example.splashydemo.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                 <action android:name="com.google.app.splashy.CLEARSPLASH"></action>
                 <category android:name="android.intent.category.DEFAULT"></category>
                 </intent-filter>
        </activity>
         <activity

//这里是闪屏文件的路径
            android:name="com.example.splashydemo.SplashyDemo"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
