title: Add margin or padding to RadioButton into a RadioGroup programmatically
body: <p>I would like to add margin or padding to a RadioGroup programmatically but it not working.</p>
  
  <p><strong>RadioButton:</strong></p>
  
  <pre><code>&lt;RadioButton xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:background="@drawable/ic_fruit"
      android:button="@null"
      android:checked="false" /&gt;
  </code></pre>
  
  <p><strong>RadioGroup:</strong></p>
  
  <pre><code>&lt;RadioGroup
              android:id="@+id/radio_group"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:layout_marginBottom="10dp"
              android:layout_marginTop="10dp"
              android:orientation="horizontal"&gt;
  
  &lt;/RadioGroup&gt;
  </code></pre>
  
  <p><strong>Java code:</strong></p>
  
  <pre><code>RadioButton radioButtonView = (RadioButton) getActivity().getLayoutInflater().inflate(R.layout.radio_button, null);
  
  radioGroup.addView(radioButtonView);
  </code></pre>
  
  <p>I tried to use <code>LayoutParams</code> and <code>dividerPadding</code> but it not works</p>
