Android - Get ListView item height?

Question

Is there a way to get ListViewItem height in code, when there is no actual items in list?

My ListViewItem layout:

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="?android:attr/listPreferredItemHeight">
...
</LinearLayout>  

I have tried to get it using Inflater:

View convertView = LayoutInflater.from( this )
    .inflate( R.layout.mail_list_row, null );
int itemHeight = convertView.getHeight();

But it's return 0;

Thanks!

Try this, it will work for you.

private static final int UNBOUNDED = MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED);

// To calculate the total height of all items in ListView call with items = adapter.getCount()
public static int getItemHeightofListView(ListView listView, int items) {
    ListAdapter adapter = listView.getAdapter();

    int grossElementHeight = 0;
    for (int i = 0; i < items; i++) {
        View childView = adapter.getView(i, null, listView);
        childView.measure(UNBOUNDED, UNBOUNDED);
        grossElementHeight += childView.getMeasuredHeight();
    }
    return grossElementHeight;
}
