如何让项目在列表视图中点击？ [英] How to make items clickable in list view?

问题描述

我一直在试图寻找一个解决方案，但很少成功。
我要显示弹出窗口包含的项目列表。
我能够显示窗口，但 onitemclicklistener 没有被要求单击列表视图的项目。这个问题的任何帮助将大大AP preciated。

I have been trying to search for a solution, but with very little success. I have to display a pop up window containing a list of items. I was able to display the window but onitemclicklistener is not being called upon clicking an item in the list view. Any help with this issue would be greatly appreciated.

感谢

EDIT1：

public class PopUpWindowActivity extends Activity {

    /** Called when the activity is first created. */
    String[] countries = new String[] {
        "India", "USA", "Canada"
    };

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        LinearLayout ll = new LinearLayout(this);
        ListView lv = new ListView(this);
        lv.setAdapter(new ArrayAdapter < String > (this, android.R.layout.simple_list_item_1, countries));
        lv.setOnItemClickListener(new OnItemClickListener() {

                public void onItemClick(AdapterView <? > arg0, View arg1, int arg2,
                    long arg3) {
                    Log.v("clicked", (String)((TextView) arg1).getText());
                }

            });
        ll.addView(lv);
        setContentView(ll);
    }
}

在上面的code，我试图创建布局里面，我增加了一个列表视图。这使得列表视图不再点击。我必须这样做，因为，我想实现一个弹出窗口，其内部应该有多个项目进行列表视图一起。

In the above code, i tried to create a layout inside which i added a list view. This makes the list view no longer clickable. I have to do this because, i am trying to implement a pop up window inside which there should be multiple items along with a list view.
