android - Set ListView item height

Question

this should be a very easy thing to do, but it looks like it's very tricky. In my code I have this ListView:

<ListView android:id="@+id/sums_list" android:layout_width="fill_parent"
        android:layout_height="0dp" android:layout_weight="1" android:dividerHeight="0dp"></ListView>

That is populated with an ArrayAdapter that uses this view:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:cdpb="http://schemas.android.com/apk/res/ale.android.brainfitness"
    android:orientation="vertical" android:layout_width="fill_parent"
    android:layout_height="55dp">
...
</LinearLayout>

Why isn't the item 55dp high?

Thanks everybody

Answer 1

How are you inflating the view?

If you are setting 'parent' parameter to null like below, then layout parameters are ignored.

@Override
public View getView(int position, View convertView, ViewGroup parent) {
  ...
  View v = inflater.inflate(R.layout.filtered_trip_row, null);
  …

  return v;
}

Passing 'parent' to inflate should work as you expect.

@Override
public View getView(int position, View convertView, ViewGroup parent) {
  ...
  View v = inflater.inflate(R.layout.filtered_trip_row, parent);
  …

  return v;
}

This explains it in detail: Why does LayoutInflater ignore the layout_width and layout_height layout parameters I've specified?

To avoid getting UnsupportedOperationException, you can add false as an input parameter to the inflator. Example:

inflater.inflate(R.layout.filtered_trip_row, parent, false)
