Netease news has a small function. Although its functions are small, we can see that the product design of large companies is indeed very good. Today we have implemented the next function, if you click "Night mode" or "Daytime mode", all activity backgrounds must be changed. In fact, the android Source Code defines an id for each activity content area, that is, android. r. id. content, because the background of all activities must change color, you must write a base class. The Code is as follows:

Public class BaseActivity extends Activity {protected void onCreate (android. OS. bundle savedInstanceState) {super. onCreate (savedInstanceState) ;}; @ Overridepublic void setContentView (int layoutResID) {super. setContentView (layoutResID); (ViewGroup) findViewById (android. r. id. content )). getChildAt (0 )). setBackgroundColor (getResources (). getColor (true? R. color. root_view_background_color_night: R. color. root_view_background_color ));}}

When a user clicks the day or night mode, a value must be stored in SharedPreferences. In the code above, the value is true. If the real project is definitely read from the SharedPreferences file, that's it. It's easy!
