Question

Hello fellow developers.

I have a Grid View in an android application. The grid view has the setting to automatically fit the number of columns and has a minimum column width of 250 pixels.

Inside the grid cells, I have a LinearLayout that has an Image View and some Text Views.

I want my Image View to be always square, but unfortunately I was not able to do this with any layout settings (open to suggestions here, if there is an option I missed).

So my idea is that I should somehow get the grid column width in my image Loading class and adjust the imageView height dynamically there, to match the width.

I failed getting the column width though.
If I set a breakPoint in my public View getView(int position, View convertView, ViewGroup parent) I see that my parent ViewGroup is the Grid and it has the correct value of the column width, but when I use:

GridView mGridView = (GridView)parent;
int width = mGridView.getColumnWidth();

the app crashes as it says there is no getColumnWidth method.

Any help here?

The solution may be extending your ImageView and overriding onMesure() method according to your requirement:

onMeasure(int widthMeasureSpec, int heightMeasureSpec){
   super.onMeasure(widthMeasureSpec,heightMeasureSpec);
   setMeasuredDimension(getMeasuredWidth(),getMeasuredWidth());

}
