[Do not hate those that are not open source] Xiaomi's rice UI's BOTTOMVIEW source code is perfectly decompiled

The principle is the combination of WindowManager Dialog and Animation.

Here we will share a very classic, practical and simple Third-Party UI control library for Android: BottomView (this is also used by Mi UI of Xiaomi)

Functions:

You can customize the layout in the View popped up at the bottom;

You can customize whether the image can be touched and the image disappears;

You can customize events;

You can customize whether the peripheral background is transparent;

You can customize animations;

If needed, you can force the display of the Top View

Usage:

1. Download The BottomView. jar library file and put it in libs of the Android project.

2. Set the Theme of BottomView:

Copy and paste the two Theme files to res/values/styles. xml of your project.

Copy code
If you are prompted Copy code
If white cannot be found here, it means that the res/values/color. xml of your project has not been created or the value of white color does not exist. You only need to add it to res/values/color. xml.
Copy code
This white value is enough.

In addition, the animation Theme of the View is optional. We recommend that you copy the animation to it. The Code is as follows:

Copy codeRes/anim/bottomview_anim_enter.xml Copy code
Res/anim/bottomview_anim_exit.xml
Copy code


Overall:

2. Some core code:

Copy code

To obtain this View, call the. getView () method.
