Android网格根据屏幕密度查看图像大小

Question

The grid view of my application has 4 rows and 4 columns. I want this to fill half screen ,irrespective of the screen size of the device. How can i set the image view size accordingly

Answer 1

在dp中定义图像视图的大小，它将根据屏幕密度设置大小。

Answer 2

The easiest way would be to set the size of the GridView in dip (device-independent pixels). You can do this via your XML layout file, explicitly or with the help of the visual editor. As device-independent pixels are essentially percentiles, the Android platform will handle resizing for you based on the size and density of the device displaying. In order words, a value of android:layout_width="50dip" will look the same on any device.
