How can I align radio buttons to the right of associated text?

Question

I have the following radio buttons inside a radio group of similar buttons. By default a button is on the left of the associated text. How do I get the button itself to be on the right of the associated text?

<RadioGroup
  android:id="@+id/points_radio_group"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:orientation="vertical" >

  <RadioButton
    android:id="@+id/do_tastk_1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:checked="true"
    android:onClick="doTask1"
    android:paddingLeft="40dip"
    android:text="@string/task_name_1"
    android:textColor="#000000" />

  <RadioButton
    android:id="@+id/do_tastk_2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:checked="true"
    android:onClick="doTask2"
    android:paddingLeft="40dip"
    android:text="@string/task_name_2"
    android:textColor="#000000" />

</RadioGroup>

Answer 1

Use

    android:button="@null"
    android:drawableRight="@android:drawable/btn_radio"

So your code will be like:

<RadioGroup
  android:id="@+id/points_radio_group"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:orientation="vertical">

  <RadioButton
    android:id="@+id/do_tastk_1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:checked="true"
    android:button="@null"
    android:drawableRight="@android:drawable/btn_radio"
    android:onClick="doTask1"
    android:paddingLeft="40dip"
    android:text="@string/task_name_1"
    android:textColor="#000000" />

  <RadioButton
    android:id="@+id/do_tastk_2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:checked="true"
    android:button="@null"
    android:drawableRight="@android:drawable/btn_radio"
    android:onClick="doTask2"
    android:paddingLeft="40dip"
    android:text="@string/task_name_2"
    android:textColor="#000000" />

</RadioGroup>

Answer 2

by using

android:button="@null"
android:drawableRight="@android:drawable/btn_radio"

you change radio button format. It is better practice just to align right,

android:layoutDirection="rtl"

on each radioButton, and text will be on left side.
