How does the GridView adapt to different screens?
Like ListView, GridView is one of the commonly used controls in projects. This article describes how to adapt GridView to screens of different sizes. First, let's take a look at one of the following:
For each behavior of four items, the spacing between the top and bottom is about 2 DP, and the image in each item is scaled or enlarged to adapt to the screen
Recently, when a project in the team develops an APP, A WebView interface is used for display instead of a native control.
One problem encountered during the development of this interface is that the fragmentation of Android causes many screen resolutions. Screens with different resolutions are compatible with the size of controls in the WebView of this interface.
Because the size of Android native controls is controlled by dp rather than pixel px
