Valid layout params for RadioButtons
<p>What layout parameter could I use to make my RadioButtons<code>layout_alignParentStart</code> and Below a View? In Android studio, doing this creates an error. Or is there an attribute of some sort I could add to the RadioGroup?</p>

<p>here is the code:</p>

<pre><code>   &lt;RadioGroup
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"&gt;

    &lt;RadioButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/radio_button"
        android:id="@+id/radioButton"
        android:layout_below="@+id/text7"
        android:layout_alignParentStart="true"
        android:textSize="12sp"
        android:textColor="#000000"
        android:onClick="onRadioButtonClicked"/&gt;
    &lt;RadioButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/radio_button2"
        android:id="@+id/radioButton2"
        android:layout_below="@+id/radioButton"
        android:layout_alignParentStart="true"
        android:textSize="12sp"
        android:textColor="#000000"
        android:onClick="onRadioButtonClicked"/&gt;
    &lt;RadioButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/radio_button3"
        android:id="@+id/radioButton3"
        android:layout_below="@+id/radioButton2"
        android:layout_alignParentStart="true"
        android:textSize="12sp"
        android:textColor="#000000"
        android:onClick="onRadioButtonClicked"/&gt;
</code></pre>
