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

Solution 1:

Try adding the following attributes into the RadioButton, it should work, this way you still get to keep the ripple effect on the radio button:

android:layoutDirection="rtl"
android:textAlignment="textStart"
android:layout_gravity="start"

Remember to set supportsRtl property to true in your application manifest.

for eg:

   <RadioGroup
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <RadioButton
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_margin="4dp"
            android:layoutDirection="rtl"
            android:textAlignment="textStart"
            android:layout_gravity="start"
            android:text="The test item a"
            android:textSize="14sp" />

         ....                       

    </RadioGroup>

would give out:

Solution 2:

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>

Solution 3:

Based on the answer of Irshu I suggest the following solution which uses the material ripple effect and produces the following outcome:

If you want the dividers as shown in the GIF than simply add a view with the height of 1 and a background color between the radiobuttons.

<RadioGroup
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:checkedButton="@+id/radioButton1">

    <RadioButton
        android:id="@+id/radioButton1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:button="@null"
        android:drawableRight="?android:attr/listChoiceIndicatorSingle"
        android:background="?android:selectableItemBackground"
        android:layoutDirection="rtl"
        android:layout_gravity="start"
        android:textAlignment="textStart"
        android:paddingBottom="10dp"
        android:paddingLeft="20dp"
        android:paddingRight="20dp"
        android:paddingTop="10dp"
        android:text="Button1"
        android:textSize="14sp" />

    <RadioButton
        android:id="@+id/radioButton2"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:button="@null"
        android:drawableRight="?android:attr/listChoiceIndicatorSingle"
        android:background="?android:selectableItemBackground"
        android:layoutDirection="rtl"
        android:layout_gravity="start"
        android:textAlignment="textStart"
        android:paddingBottom="10dp"
        android:paddingLeft="20dp"
        android:paddingRight="20dp"
        android:paddingTop="10dp"
        android:text="Button2"
        android:textSize="14sp" />

    <RadioButton
        android:id="@+id/radioButton3"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:button="@null"
        android:drawableRight="?android:attr/listChoiceIndicatorSingle"
        android:background="?android:selectableItemBackground"
        android:layoutDirection="rtl"
        android:layout_gravity="start"
        android:textAlignment="textStart"
        android:paddingBottom="10dp"
        android:paddingLeft="20dp"
        android:paddingRight="20dp"
        android:paddingTop="10dp"
        android:text="Button3"
        android:textSize="14sp" />
</RadioGroup>

Solution 4:

There is property called android:drawableRight which will set your drawable right side of your text and set android:button as null. check below piece of code:

Note: This is sample, you can apply to your all radioButton.

 <RadioButton 
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:button="@null"
             android:drawableRight="@android:drawable/btn_radio"
             android:text="Left"/>

Solution 5:

Just add:

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