title: radiobutton getleft() returns 0 when repopulate
body: <p>I have one radiogroup with database populated radiobuttons. When I repopulated them with: </p>
  
  <pre><code>Radiogroup fofo = (Radiogroup) findViewById(R.id.AperturasRadio);
      fofo.removeAllViews();
      for(int i = 0; i &lt; mStringArray.length ; i++){
              RadioButton newRadioButton;
              newRadioButton = (RadioButton)
              getLayoutInflater().inflate(R.layout.radio_template, null);
              String label = (String) mStringArray[i];
              newRadioButton.setText(label);
              newRadioButton.setId(i);
              if (label.equals("2.8")) {
                  newradiobutton.setChecked(true);
              }
              fofo.addView(newRadioButton);
              fofo.updateBackground();
  </code></pre>
  
  <p>The problem is that I have a RadioGroup.OnCheckedChangeListener who triggers a diferent method that need the CheckedRadiobutton.Getleft()</p>
  
  <pre><code>    RadioGroup.OnCheckedChangeListener listenerAperturas = new RadioGroup.OnCheckedChangeListener() {
                  public void onCheckedChanged(RadioGroup group, int id) {
  
  RadioGroup grupo1 = (RadioGroup) findViewById(R.id.AperturasRadio);
  int radioButtonID = grupo1.getCheckedRadioButtonId();
  RadioButton radiogrButton = (RadioButton) findViewById(radioButtonID);
  int left = radiogrButton.getLeft();
  Toast.makeText(getApplicationContext(), "Botton radio: " + left + " " , Toast.LENGTH_SHORT).show();
  </code></pre>
  
  <p>But the value is 0. The first time radiogroup populates works fine, but when I trigger de repopulation just returns zero.</p>
  
  <p>The layout is this:</p>
  
  <pre><code>&lt;HorizontalScrollView
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:id="@+id/horiz"
              android:scrollbars="none"&gt;
  
  &lt;LinearLayout
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"&gt;
      &lt;Space
          android:layout_width="500px"
          android:layout_height="match_parent" /&gt;
  
              &lt;com.alfbishop.testing.testbbdd.ListasBotones
              android:id="@+id/AperturasRadio"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:layout_marginTop="41dp"
              android:orientation="horizontal"&gt;
       &lt;/com.alfbishop.testing.testbbdd.ListasBotones&gt;
      &lt;Space
          android:layout_width="500px"
          android:layout_height="match_parent" /&gt;
  &lt;/LinearLayout&gt;
          &lt;/HorizontalScrollView&gt;
  </code></pre>
  
  <p>Could you help me to find a solution?</p>
