Some special properties of the GridView:

In Android, how does one automatically adapt to the number of adapters in each row of the GridView?

Android: numColumns is used to set the number of columns. You can set the number of columns to display by yourself. Of course, you can also set the number of columns dynamically based on the screen size and image size! If you do not set this parameter, gallery automatically adjusts the number of columns! I have not tried it!
 
How does android's gridview control its height?

1. To control the overall height of the widget, you can directly set layout_height through the layout, or assign a value to him dynamically, but I believe this is not what the landlord asked.
2. Control the height of each unit. Because the gridview does not directly set the cell height, while the gridview is dynamically generated based on the adapter, it is generally obtained in the getView method of the adapter (the height of the View returned by this method ), you can process it here.
