How to get the number of rows of a GridView?

Question

Is there a way to get the row count of a GridView for Android API Level 8?

Answer 1

Adding the duplicated answer here since I initially answered a duplicate question.

I added this implementation on a custom GridView subclass of mine, and it worked as expected. I checked the declared fields of the GridView class and at least on API 8 they do already have a field called mNumColumns (which is what is returned on API 18 by getNumColumns()). They probably haven't changed the field name to something else and then back between APIs 8 and 18, but I haven't checked.

@Override
public int getNumColumns() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
        return super.getNumColumns();
    } else {
        try {
            Field numColumns = getClass().getSuperclass().getDeclaredField("mNumColumns");
            numColumns.setAccessible(true);
            return numColumns.getInt(this);
        } catch (Exception e) {
            return 1;
        }
    }
}

The @Override won't cause any errors since it's just a safety check annotation AFAIK.

I also don't know if there are any counter-recommendations of doing like this instead of having a separate getNumColumnsCompat() method (as on @cottonBallPaws answer), but I found it to be pretty neat like this.
