隐藏标题栏

ActionBar actionBar=getSupportActionBar();

if(actionBar!=null){

    actionBar.hide();
}

隐藏状态栏

Window window = getWindow();

int flag = WindowManager.LayoutParams.FLAG_FULLSCREEN;

window.setFlags(flag, flag);

需在setContentView(R.layout.activity);之前写，否则报错。

全屏

android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen">

需将AppCompatActivity该为Activity
