Android: preferencescreen right to left

This xml file PreferenceScreen PreferenceCategory appears to RTL as I need, but L has other components. LTR appears How to make RTM RT?

I got attached to this link and I added android: supportsRtl = "true" for the item in my manifest file, but nothing happened!

Have you decided this?

There are two possible workarounds: extend each of the settings and add:

  @TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR1) @Override protected View onCreateView(final ViewGroup paramViewGroup) { final View view=super.onCreateView(paramViewGroup); if(VERSION.SDK_INT>=VERSION_CODES.JELLY_BEAN_MR1) view.setLayoutDirection(View.LAYOUT_DIRECTION_LOCALE); return view; }

another operation:

 if(VERSION.SDK_INT>=VERSION_CODES.JELLY_BEAN_MR1) getListView().setLayoutDirection(View.LAYOUT_DIRECTION_LOCALE);

However, for both workarounds, I cannot find how to handle the displayed dialogs by clicking on some settings.

Set CheckBoxPreference and EditTextPreference, ... in the right direction:

 public class EditTextPreferenceRTL extends EditTextPreference { public EditTextPreferenceRTL(Context context, AttributeSet attrs) { super(context, attrs); } @Override protected View onCreateView(ViewGroup parent) { View view = super.onCreateView(parent); RelativeLayout layout = (RelativeLayout) ((LinearLayout) view).getChildAt(1); layout.setGravity(Gravity.RIGHT); return view; } } public class CheckBoxPreferenceRTL extends CheckBoxPreference { public CheckBoxPreferenceRTL(Context context, AttributeSet attrs) { super(context, attrs); } @Override protected View onCreateView(ViewGroup parent) { View view = (LinearLayout)super.onCreateView(parent); RelativeLayout layout = (RelativeLayout) ((LinearLayout) view).getChildAt(1); ((LinearLayout)view).removeViewAt(1); layout.setGravity(Gravity.RIGHT); ((LinearLayout)view).addView(layout); return view; } }
