如何从Java，Android上的ListView中获取所选项目

Question

我有一个带适配器的ListView：

ListView names=(ListView)findViewById(R.id.listViewItems);

String[] items=new String[mMusicData.size()];
mMusicData.keySet().toArray(items);

ArrayAdapter<String> adapter=new ArrayAdapter<String>(this, android.R.layout.simple_list_item_single_choice, new String[]{"A", "B", "C"});
names.setAdapter(adapter);

当我尝试在其他函数中获取所选项目的ID时，我总是得到-1：

Log.e("1", String.valueOf(names.getSelectedItemPosition()));

Answer 1

names.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {
            //use POSITION to get item clicked
        }
    });
