Android ListView 单击上下文菜单

Question

我有一个项目列表，每次单击我都想显示一个自定义上下文菜单。我已经遍地查看了一个示例并尝试了很多东西，但我能想到的最接近的方法是长按菜单显示(并且每个项目的菜单都不明显)。这是代码，任何帮助都会很棒。请注意，在阅读了一堆教程后，我已经从 Activity 继承了子类。

public class EventListActivity extends Activity {

      @Override
        public void onCreate(Bundle savedInstanceState) {
              Log.i("ME", "Event List Activity Into On Create ");
            super.onCreate(savedInstanceState);
            setContentView(R.layout.event_list);
            Log.i("ME", "Event List Activity Into On Create 1 ");
            String[] values = new String[] {"Emerald Greens","Dahlgtreen","Edinborough","Pebble Creek","Gross"};
            Log.i("ME", "Event List Activity Into On Create 2");

            ListView listView = (ListView)findViewById(R.id.list);

            Log.i("ME", "Event List Activity Into On Create 2a");


            //ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.event_list,R.id.label,values);
            ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.event_list_item,values);

            Log.i("ME", "Event List Activity Into On Create 3");
            //setListAdapter(adapter);
            listView.setAdapter(adapter);
            Log.i("ME", "Event List Activity Into On Create 4");

            registerForContextMenu(listView);
            Log.i("ME", "Event List Activity Into On Create 6");

      }




    protected void onListItemClick(ListView listView, View v, int pos, long id) {
        String item = (String)listView.getAdapter().getItem(pos);
        Toast.makeText(this, item+" Selected pos:"+pos+":   id:"+id+":", Toast.LENGTH_LONG).show();


    }   


    @Override
    public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
        Log.i("ME", "OnCreateContextMenu ");
      if (v.getId()==R.id.list) {
        AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo)menuInfo;
        //menu.setHeaderTitle(Countries[info.position]);
        menu.setHeaderTitle("Blippo");
        //String[] menuItems = getResources().getStringArray(R.array.menu);
        String[] menuItems = new String[] {"Menu a","Menub"};
        for (int i = 0; i<menuItems.length; i++) {
          menu.add(Menu.NONE, i, i, menuItems[i]);
        }
      }
    }

    @Override
    public boolean onContextItemSelected(MenuItem item) {
      AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo)item.getMenuInfo();
      int menuItemIndex = item.getItemId();
      //String[] menuItems = getResources().getStringArray(R.array.menu);
      String[] menuItems = new String[] {"Menu a","Menub"};
      String menuItemName = menuItems[menuItemIndex];

      //String listItemName = Countries[info.position];
      String listItemName = "hardcoded";

      Toast.makeText(this, item+" Selected Submenu", Toast.LENGTH_LONG).show();

      return true;
    }

    }

您可以为此使用滑动抽屉，点击每个项目即可打开滑动抽屉并显示您的项目
