继承AppCompatActivity的Activity隐藏标题栏

1、activity中：

super.onCreate(savedInstanceState);        this.supportRequestWindowFeature(Window.FEATURE_NO_TITLE); //去除这个Activity的标题栏        setContentView(R.layout.activity_menu_choose_list_dialog);

2、androidmanifest中：

android:theme="@style/Theme.AppCompat.Light.NoActionBar">
