android listview checkbox event

Question

i'm trying to implement custom listview. however, i can't get the click event for my checkbox;

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    final int pos = position;
    View view = convertView;

    if(view == null){
        LayoutInflater layoutInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        view = layoutInflater.inflate(R.layout.listview,parent, false);
    }
    TextView textview = (TextView)view.findViewById(R.id.listview_text);
    final CheckBox checkbox = (CheckBox)view.findViewById(R.id.listview_check);
    checkbox.setFocusable(false);
    checkbox.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(context, pos+"", Toast.LENGTH_SHORT).show();
        }
    });

    return super.getView(position, convertView, parent);
}

I want that if I clicked checkbox in ListView, pop the Toast about row position. But, this code run just check box click event just 0 row. checkbox in other row don't trigger event.

how can i fix it?

the last line in getView() seems suspect. you should be returning the view you created or convertView passed to you.

Onclicklisteners on check boxes wont work.

usually check box click listeners should be like this

CheckBox chkbbx = (CheckBox) findViewById(R.id.chkbbx);
chkbbx.setOnCheckedChangeListener( new OnCheckedChangeListener() {

@Override
public void onCheckedChanged(CompoundButton arg0, boolean arg1) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "Check box "+arg0.getText().toString()+" is "+String.valueOf(arg1) , Toast.LENGTH_LONG).show();
  }
} );
