Android：当我为ListView设置OnClickListener时

Question

    lv.setOnClickListener(new OnClickListener(){
        public void onClick(View v){

        }
    });

Does v refer to the ListView lv or the specific item selected in the list?

Answer 1

I believe that v refers to the whole ListView . To add a click handler for an item, you want to use AdapterView.setOnItemClickListener .

Answer 2

你想要的是一个setOnItemClickListener。

Answer 3

onClickListener just listens to a click on the entire View. v will be the ListView .

What you probably want is onItemClickListener instead of onClickListener .

Or you may want to extend ListActivity and override onListItemClick()

Answer 4

listView.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> arg0, View view, int arg2,long itemID) {

        View itemView = view;
        String fromDate = ((TextView)itemView.findViewById(R.id.fromDate)).getText().toString();
        int position = (int) arg0.getSelectedItemId();
        Log.d(TAG, "ListView Selected : "+fromDate+" Position:"+position+" arg2:"+arg2+" arg3:"+itemID);
    }
});
