Android 标题栏和图标

Question

当我的应用程序启动时，我看到标题栏和应用程序名称带有白色活动。 尽管我的 mainactivity 是一个启动画面，但它一开始并没有开始，而是在这个标题栏和白色活动的 2 秒后开始。我如何禁用它。

感谢您的帮助！

Splash.java

`public class Splash extends Activity {

    @Override
    protected void onCreate(Bundle parameter) {
        // TODO Auto-generated method stub
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.splash);
        super.onCreate(parameter);
        Thread timer= new Thread()
        {
            @Override
            public void run()
            {
                try
                {
                    //Display for 3 seconds
                    sleep(3000);
                }
                catch (InterruptedException e) 
                {
                    // TODO: handle exception
                    e.printStackTrace();
                }
                finally
                {   
                    //Goes to Activity  StartingPoint.java(STARTINGPOINT)
                    Intent openstartingpoint=new Intent("com.vault.beta.MAINACTIVITY");
                    startActivity(openstartingpoint);
                }
            }
        };
        timer.start();
    }

    @Override
    protected void onPause() {
        // TODO Auto-generated method stub
        super.onPause();
        finish();
    }

}
