title: Unchecking a radio button
body: <p>The application is a step sequencer application with 16 radio groups with 8 buttons in each group. It works perfectly except once a group has a button selected I cant turn it off unless I use the clear button I have created to clear all radiogroups. What I would like to add is some code that says when a selected radio button is selected again it simply turns off like a toggle. I tried using toggles but then other issues arose with that method. Below is an attempt at it but it is way off the mark Im guessing</p>
  
  <pre><code>final RadioGroup radioGroup1 = (RadioGroup)findViewById(R.id.RadioGroup1);
  RadioButton lC1 = (RadioButton)findViewById(R.id.RadioButtonlowC1);
  
  Button D1 = (Button)findViewById(R.id.RadioButtonD1);
          D1.setOnClickListener(new View.OnClickListener() {
  
              @Override
              public void onClick(View v) {
                  PdBase.sendFloat("D1", 74);
                  int selectedTypeId = radioGroup1.getCheckedRadioButtonId();
                  RadioButton D1 = (RadioButton) findViewById(selectedTypeId);
                  if(radioGroup1 != null) // This will be null if none of the radio buttons are selected
                         radioGroup1.clearCheck(); 
                  PdBase.sendFloat("D1", 0);
              }
          });
  </code></pre>
