Question

我有一个ListView，需要检查，哪个项目已被点击。我拥有它的方式，当我使用鼠标的滚轮（在Eclipse模拟器中测试时）时，它只显示我选择的项目。当我在真实的移动设备上测试时，它根本没有反应。

adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, listItems);
listView.setAdapter(adapter);

listView.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

    public void onItemSelected(AdapterView<?> arg0, View arg1,
            int arg2, long arg3) {
        myFunction(listView.getSelectedItem());
    }

    public void onNothingSelected(AdapterView<?> arg0) {
        // TODO Auto-generated method stub
    }
});

Answer 1

使用setOnItemClickListener 代替 setOnItemSelectedListener

listView.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position,
                    long id) {
            //get value for listItems using position    

                     String str =listItems[position];                   
                     myFunction(str);
            }
        });

Answer 2

我认为你需要在onListItemClick监听器上使用

     public void onListItemClick(ListView parent, View v, int position, long id)
              {
                parent.setItemChecked(position, parent.isItemChecked(position));
         Toast.makeText(this,  "You have selected" + items[position],30).show();
                }

检查ListView的选定项目
