public class RtlEditTextPreference extends EditTextPreference {
public RtlEditTextPreference(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public RtlEditTextPreference(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
}

public RtlEditTextPreference(Context context) {
    super(context);
}

@Override
protected View onCreateView(ViewGroup parent) {
    View view = super.onCreateView(parent);

    RelativeLayout relativeLayout = (RelativeLayout)(((LinearLayout)view).getChildAt(1));
    relativeLayout.setGravity(Gravity.RIGHT);

    TextView title = (TextView) relativeLayout.getChildAt(0);
    TextView summary = (TextView) relativeLayout.getChildAt(1);

    RelativeLayout.LayoutParams titleLayoutParams = (RelativeLayout.LayoutParams)title.getLayoutParams();
    titleLayoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
    title.setLayoutParams(titleLayoutParams);

    RelativeLayout.LayoutParams summaryLayoutParams = (RelativeLayout.LayoutParams)summary.getLayoutParams();
    summaryLayoutParams.addRule(RelativeLayout.ALIGN_RIGHT, title.getId());
    summaryLayoutParams.addRule(RelativeLayout.ALIGN_LEFT, -1); // Override default left alignment to the title
    summary.setLayoutParams(summaryLayoutParams);

    return view;
}

}
