Set LayoutDirection (RTL) for api lower than 17

Question

I am going to build a Persian app (RTL). my app includes a ListView and a Navigation Drawer .

I added in Manifest in application tag android:supportsRtl="true"

and in onCreate() method: getWindow().getDecorView().setLayoutDirection(View.LAYOUT_DIRECTION_RTL);

I know that LayoutDirection for less than 17 api does not work.

for api level 17 and higher:

for api lower than 17:

How do I solve this problem. 1- Putting a conditional statement to check the android api and assign a particular layout ? 2-use folder layout-ldrtl in eclipse? 3 - ... ? What is the best way??

Answer 1

use ViewCompat from android.support.v4.view.ViewCompat !

like this :

ViewCompat.setLayoutDirection (View yourView, int layoutDirection)

layoutDirection is a constant from ViewCompat class

Answer 2

Just concatenate every string that you want to set in textView with "\u202B"

it just enforces the text to be RTL.

String textWhichIsLTR = "LTR or RTL text that you want to enforce to RTL";
String enforcedRTL = textWhichIsLTR + "\u202B";
fooTextView.setText(enforcedRTL);
