Framelayout frame layout of Android layout _android

Objective

As one of the simplest layouts in the Android six-part layout, the layout creates a blank area directly on the screen,

When we add components to the inside, all the components are placed in the upper-left corner of the area.

The size of the frame layout is determined by the largest child control in the control, and if all components are the same, you can only see the topmost component at the same time!

Of course, we can also add the Layout_gravity attribute to the component to develop the way the component is

The frame layout is used more in the game development aspect, later will give everybody to demonstrate the more interesting two examples
