我一直在努力寻找解决方案,但收效甚微.
我必须显示一个包含项目列表的弹出窗口.
我能够显示窗口,但单击列表视图中的项目时未调用onitemclicklistener.任何有关此问题的帮助将不胜感激.

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);
}
}
在上面的代码中,我试图创建一个布局,其中我添加了一个列表视图.这使列表视图不再可单击.我必须这样做因为,我正在尝试实现一个弹出窗口,其中应该有多个项目以及列表视图.
