Custom Single choice ListView

I've been searching for an answer to this problem all morning, and the most useful thing I've found so far is this article.

While I haven't implemented the solution it suggests yet, it sounds like it's on the right track.

Basically, the single-choice ListView expects the widgets you provide it with to implement the Checkable interface. LinearLayout and others don't. So you need to create a custom layout that inherits LinearLayout (or whatever layout you want to use for your items) and implements the necessary interface.

I had a similar situation but fixed that easily. Try this:

1. Extend ListActivity and set your custom list adapter

   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       requestWindowFeature(Window.FEATURE_NO_TITLE); //if you need title to be hidden
       setContentView(R.layout.activity_add_to_cart_select_service_plan);
       setListAdapter(adapter);
   }
   

2. Create a field to store selected index position in adapter

   int selectedIndex = -1;
   

3. Provide an interface to it

   public void setSelectedIndex(int index){
       selectedIndex = index;
   }
   

4. Set the checked state to true or false based on the selected index inside getView()

   @Override
   public View getView(int position, View convertView, ViewGroup parent) {
       RadioButton rbSelect = (RadioButton) convertView
                           .findViewById(R.id.radio1);
       if(selectedIndex == position){
       rbSelect.setChecked(true);
       }
       else{
       rbSelect.setChecked(false);
       }
   }
   

5. Set radio button focusable and clickable attribs to 'false'

    <RadioButton
        android:id="@+id/radio1"
        android:checked="false"
        android:focusable="false"
        android:clickable="false"
    />
   

6. Set listview descendantFocusability attrib to 'beforeDescendants'

   <ListView
       android:id="@android:id/list"
       android:choiceMode="singleChoice"
       android:descendantFocusability="beforeDescendants"
   />
   

7. Override onListItemClick

   @Override
   protected void onListItemClick(ListView l, View v, int position, long id) {
       super.onListItemClick(l, v, position, id);
       adapter.setSelectedIndex(position);
       adapter.notifyDataSetChanged();
   }
   

That's it..run and check
