Method of adding floating button on tableview in Android Development

If you paste a button directly on the tableviewcontroller, it will cause the button to scroll. Here are two methods to implement the position fixed floating button on the tableview:

　　1. Paste tableview on the view, and then paste the hover button on the top of the view

　　2. Using window

First, take a look at the final effect. Add a floating button on the tableview controller, which cannot scroll with the view

First, introduce the first method above:

1) Create properties for tableview and bottom button

2) Create attribute to top

3) Implement button events

Next, the second method is introduced:

1) Create a window, and the button attribute prevents the window from being released

2) Creating windows and buttons

By default, the system has only one window. In this case, we need to set windowlevel

Window does not need to be added to any view

3) Delay loading the window. Note that we need to create this floating button after the rootwindow is created

4) Implement button events

Note: finally, add a small function to make the button animation appear and disappear when the tableview slides up and down. Here, pull up to disappear and pull down to appear
