第一种方法：
public class SplashScreen extends Activity
{

private Thread mSplashThread;

public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

final ImageView splashImageView = (ImageView) findViewById(R.id.SplashImageView);
splashImageView.setBackgroundResource(R.drawable.flag);

final AnimationDrawable frameAnimation = (AnimationDrawable) splashImageView
.getBackground();

splashImageView.post(new Runnable()
{
public void run()
{
frameAnimation.start();
}
});

mSplashThread = new Thread()
{
public void run()
{
try
{

synchronized (this)
{
wait(2000);
}
}
catch (InterruptedException ex)
{
}
finish();
}
};

mSplashThread.start();
}
}
main.xml文件：
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/TheSplashLayout"
