Question

here’s the code, I have problem with:

        listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, android.view.View view,
                int position, long id) {

            if(listview.isItemChecked(position)){

            } 

            if(listview.getCheckedItemCount()>1){

            }

        }
    });

it keeps saying that listener must override superclass method and that I cant call non-final variable “listview” inside inner class. how am I supposed to call listview.isItemChecked(position) then? thanks

I’d suggest you read up on the use of final in Java. Technically, you could fix this by adding the keyword final before ListView listview = ..., so final ListView listview = ....

However, a better option is to just use the passed reference to ListView in your OnItemClick-method. The parameter AdapterView<?> Parent corresponds to your ListView, so you can use the following code:

listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> parent, android.view.View view,
            int position, long id) {

        ListView lv = (ListView) parent;

        if(lv.isItemChecked(position)){
            // ...
        } 

        if(lv.getCheckedItemCount()>1){
            // ...
        }

    }
});
