延时实现，Handle

//延时

Handler x = new Handler();  

        x.postDelayed(new splashhandler(), 2000);//延时2秒，接着往下面做就是splashhandler（）；  


 //延时实现掉跳转
class splashhandler implements Runnable{  

public void run() {  
startActivity(new Intent(getApplication(),MainMapView.class));  
NewsMapActivity.this.finish();  
}
