Solution
The issue is that Android doesn't allow you to select list items that have elements on them that are focusable. I modified the checkbox on the list item to have an attribute like so:
android:focusable="false"
android:focusableInTouchMode="false"
Now my list items that contain checkboxes (works for buttons too) are "selectable" in the traditional sense (they light up, you can click anywhere in the list item and the "onListItemClick" handler will fire, etc).
OTHER TIPS
Add android:focusable=false in checkbox of custom_class.xml
Add this
android:descendantFocusability="blocksDescendants
to the root element in custom_class.xml
Probably checkbox takes focus when you click on list item. So just add the above to the root element in xml.
android:descendantFocusability
Defines the relationship between the ViewGroup and its descendants when looking for a View to take focus.
Must be one of the following constant values.
Constant Value Description
beforeDescendants 0 The ViewGroup will get focus before any of its descendants.
afterDescendants 1 The ViewGroup will get focus only if none of its descendants want it.
blocksDescendants 2 The ViewGroup will block its descendants from receiving focus.
This corresponds to the global attribute resource symbol descendantFocusability.
You can also add
android:focusable= "false"
for the checkbox
android:focusable
Boolean that controls whether a view can take focus. By default the user can not move focus to a view; by setting this attribute to true the view is allowed to take focus. This value does not impact the behavior of directly calling requestFocus(), which will always request focus regardless of this view. It only impacts where focus navigation will try to move focus.
Must be a boolean value, either "true" or "false".
Change
mListView.setOnItemClickListener(new AdapterView.OnItemClickListener()
to
mListView.setOnItemClickListener(new OnItemClickListener()
mListView.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0, View arg1,int arg2, long arg3) {
Intent mIntent = new Intent(Classes_Ext_DB.this,
RecordAudio.class);
startActivity(mIntent);
}
});
Have you tried android:focusable="false" on the checkbox ?
