    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        getSupportActionBar().hide();//去除标题栏

    }
    private void startMainActivity(){
        TimerTask delayTask = new TimerTask() {
            @Override

                Intent mainIntent = new Intent(MainActivity.this,MainActivity2.class);
                startActivity(mainIntent);
                MainActivity.this.finish();
            }
        };
        Timer timer = new Timer();
        timer.schedule(delayTask,3000);//延时两秒执行 run 里面的操作
    }
}
