Activity full screen and hide title bar

Core code:

requestWindowFeature(Window.FEATURE_NO_TITLE);//去标题    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);//全屏显示

If the above code is to be written before Activity.setcontentview (), it is not valid.

Activity switching between the two

Core code:

new Intent();intent.setClass(Activity1.this, Activity2.class);startActivity(intent);

The implementation jumps from Activity1 to Activity2.
