                android:numColumns="auto_fit"

Answer 1

您可以在java代码中获取列数.

GridView mGridView = (GridView)findViewById(R.id.gridview);
int column_coutnt = mGridView.getNumColumns();

第二种方式:

int columns = 0;
int children = mGridView.getChildCount();
if (children > 0) {
     int width = mGridView.getChildAt(0).getMeasuredWidth();
     if (width > 0) {
        columns = mGridView.getWidth() / width;
     }
 }
