安卓——Handler延迟跳转

//声明控制对象  Handler handler =new Handler(){

        @Override  public void handleMessage(Message msg) {
            super.handleMessage(msg);
            Intent intent=new Intent(MainActivity.this,Main2Activity.class);
            startActivity (intent);
            finish();

        }
    };
    //延迟发送1000毫秒控制信息 显示主页面  handler.sendEmptyMessageDelayed(1,1000);
}
