CheckBox in a row of ListView

问题

How do I override a CheckBox's default onClick() behaviour?

Use case I want the checkBox to reflect some boolean status of the object being rendered in the row view. When the user clicks on the row (including the checkBox), some process will run which may alter the objects state (the boolean variable).

Now how do I prevent the CheckBox's default onClick behaviour from kicking in? In other words I want CheckBox.onClick() to call theCustomAdapter.onItemClick(). How do I achieve this?

On a second thought, is there any such widget object which just displays an on/off status & does not implement Clickable?

Custom Adapter

public class UserListViewAdapter extends ArrayAdapter<User> implements AdapterView.OnItemClickListener
{
    private final Context context;
    private final List<User> users;

    public UserListViewAdapter(Context context, int resource, List<User> users)
    {
        super(context, resource, users);
        this.context = context;
        this.users = users;
    }

    public View getView(int position, View convertView, ViewGroup parent)
    {
        LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View row = layoutInflater.inflate(R.layout.user, parent, false);

//        set the loggedIn? isCurrent? radio buttons
        CheckBox checkBox = (CheckBox) row.findViewById(R.id.isLoggedIn);
        checkBox.setChecked(users.get(position).isLoggedIn());
        checkBox = (CheckBox) row.findViewById(R.id.isCurrent);
        checkBox.setChecked(users.get(position).isCurrent());

//        fill the user name
        TextView textView = (TextView) row.findViewById(R.id.userName);
        textView.setText(users.get(position).getUserName());

//        fill the user id
        textView = (TextView) row.findViewById(R.id.userId);
        textView.setText(users.get(position).getUserId());

//        return the row
        return row;
    }

//    @Override
    public void onItemClick(AdapterView<?> adapterView, View view, int i, long l)
    {
        Log.i("Clicked", adapterView.toString());
        Toast.makeText(this.context, "Clicked! "+l, Toast.LENGTH_LONG).show();
    }
}

Custom Row View

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="horizontal"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
            android:gravity="center"
        android:clickable="true">
    <CheckBox android:layout_height="wrap_content"
                 android:layout_width="wrap_content"
                 android:id="@+id/isLoggedIn"
                 android:padding="4dp"
                android:gravity="center"
            android:focusable="false"
            android:clickable="false"
            android:focusableInTouchMode="false"/>
    <CheckBox android:layout_height="wrap_content"
                 android:layout_width="wrap_content"
                 android:id="@+id/isCurrent"
                 android:padding="4dp"
                 android:gravity="center"
                android:focusable="false"
                android:clickable="false"
                android:focusableInTouchMode="false"/>
    <TextView android:layout_height="wrap_content"
              android:layout_width="wrap_content"
              android:id="@+id/userName"
              android:padding="4dp"
            android:gravity="left"
            android:focusable="false"
            android:clickable="false"
            android:focusableInTouchMode="false"/>
    <TextView android:layout_height="wrap_content"
              android:layout_width="wrap_content"
              android:id="@+id/userId"
              android:padding="4dp"
            android:gravity="left"
            android:focusable="false"
            android:clickable="false"
            android:focusableInTouchMode="false"/>
</LinearLayout>

An alternative to CheckBoxes are Toggle Buttons:

In the example you can see how you can make the ToggleButton decide on its own if it toggles or not, depending on whatever condition you may want to set.
