Android: How to maximize PreferenceFragment width (or get rid of margin)?

Question

Answer 1

Finally, I found the solution to this.

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View v = super.onCreateView(inflater, container, savedInstanceState);
    if(v != null) {
        ListView lv = (ListView) v.findViewById(android.R.id.list);
        lv.setPadding(10, 10, 10, 10);
    }
    return v;
}

You can set padding by using: setPadding();
