Android新手.我在调试器透视图中收到以下消息:

源附件不包含文件ListView.class的源您可以通过单击下面的更改源来更改源附件

不用说应用程序错误.我试图将源附件更改为位置路径:

C:/ Program Files/Android/android-sdk-windows/platforms/android-8/android.jar

任何想法将不胜感激.

代码是:

import android.app.ListActivity;

import android.view.*;
import android.widget.*;


public class HelloListView extends ListActivity 
{
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);

      setListAdapter(new ArrayAdapter<String>(this, R.layout.main, COUNTRIES));

      ListView lv = getListView();
      lv.setTextFilterEnabled(true);

     lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View view,
            int position, long id) {
          // When clicked, show a toast with the TextView text
          Toast.makeText(getApplicationContext(), ((TextView) view).getText(),
              Toast.LENGTH_SHORT).show();
        }
      });
    }
