推荐答案

OKK​​您可以用编程方式设置的列数

Okk you can set number of columns programatically using

float scalefactor = getResources().getDisplayMetrics().density * 100;
int number = getWindowManager().getDefaultDisplay().getWidth();
int columns = (int) ((float) number / (float) scalefactor);
gridView.setNumColumns(columns);

其中100是每个列对M取所有设备的固定宽度......我得到的平板电脑，3 8列三星三星笔记2.2设备和4

where 100 is the fixed width of each column for all devices m taking...i get 8 columns in tablet,3 in samsung 2.2 devices and 4 in samsung note
