i have read these answers in this question, but nothing has helped me :(

please help me...

I don't know about your code but. You have to create a Arabic String file in android there you can use the hint in Arabic and there is one default String which is in English.
So while running your application change your phone language to Arabic. and your string will automatically work

add this line in manifest

 <application
 ...
 android:supportsRtl="true"
 ... >
 </application>

I found the solution!

to solve this problem, you need to delete inputType attribute and it's will work fine.

or you can do this :

<EditText
 ...
 android:inputType="none" />

But you cannot change the inputType attribute.

because if you changed it, the hint will be empty if the hint was arabic
