Sample Code of the menu at the bottom of the Android imitation QQ space

I used to see the Demo at the bottom of the Android imitation QQ space on the Internet. I found that this Demo has many bugs and many mysterious figures are used for layout. So I studied the implementation of the menu at the bottom of the QQ space and wrote one for your reference. Shows the effect:

1. The implementation principle is very simple. The bottom menu is a horizontally distributed LinearLayout, which contains five LinearLayout. Their layout_weight values are 1, this means that the sub-control of the bottom menu divides the screen width equally into five parts. Five LinearLayout except the middle one, all others are placed in the ImageView and TextView (the middle is empty first, nothing is put, followed by the chassis and the plus sign ).
2. the plus sign in the center and the chassis are implemented using FramLayout. Now, the base is placed at the center of the bottom, and the plus sign is placed at the same position.
3. Set the touch event of the plus sign. The pop-up window is implemented using PopupWindow, and then replace the image of the plus sign with the multiplication number. The Code is as follows:

This Demo is just like a play, and may not be well written in some places. If you have any questions, I hope you can point them out. Thank you!
