how to put the text on the left of a radio button in android

I want to put the text of a radio button on the left not on the right

I found this solution

        <RadioGroup
        android:id="@+id/radios"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_gravity="right"
        android:inputType="text"
        android:orientation="vertical" >

        <RadioButton
            android:id="@+id/first"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="right"
            android:background="@color/white"
            android:button="@null"
            android:drawablePadding="30dp"
            android:drawableRight="@android:drawable/btn_radio"
            android:text="first"
            android:textColor="@color/Black"
            android:textSize="20dip" />

        <RadioButton
            android:id="@+id/second"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:background="@color/Black"
            android:button="@null"
            android:drawablePadding="30dp"
            android:drawableRight="@android:drawable/btn_radio"
            android:text="second"
            android:textColor="@color/White"
            android:textSize="20dp" />

        <RadioButton
            android:id="@+id/third"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:background="@color/Maroon"
            android:button="@null"
            android:drawablePadding="30dp"
            android:drawableRight="@android:drawable/btn_radio"
            android:text="third"
            android:textColor="@color/Vanilla"
            android:textSize="20dp" />
    </RadioGroup>

but the problem is that the text gravity will be at the left what I want is to put it to right because i'm writing Arabic words

enter image description here

Solution

Add android:gravity="right" in each RadioButton as follow..

  <RadioGroup
    android:id="@+id/radios"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_gravity="right"
    android:inputType="text"
    android:orientation="vertical" >

    <RadioButton
        android:id="@+id/first"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="right"
        android:background="@color/white"
        android:button="@null"
        android:drawablePadding="30dp"
        android:drawableRight="@android:drawable/btn_radio"
        android:text="first"
        android:textColor="@color/Black"
        android:textSize="20dip" 
        android:gravity="right"/>

    <RadioButton
        android:id="@+id/second"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@color/Black"
        android:button="@null"
        android:drawablePadding="30dp"
        android:drawableRight="@android:drawable/btn_radio"
        android:text="second"
        android:textColor="@color/White"
        android:textSize="20dp"
         android:gravity="right"/>

    <RadioButton
        android:id="@+id/third"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@color/Maroon"
        android:button="@null"
        android:drawablePadding="30dp"
        android:drawableRight="@android:drawable/btn_radio"
        android:text="third"
        android:textColor="@color/Vanilla"
        android:textSize="20dp"
        android:gravity="right" />
</RadioGroup>
