ContextMenu項目選擇？

Question

我正在做一個音樂文件的各種類型的操作的上下文菜單。但我無法獲得上下文菜單項選擇。在下面的代碼test4contextmenu是一個包含TextView佈局的類。

public boolean onContextItemSelected(MenuItem item) { 
     AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo)item.getMenuInfo(); 
     int menuItemIndex = item.getItemId(); 

     String menuItemName = menuItems[menuItemIndex]; 
     String songName = songs.get(info.position); 

     text = (TextView)findViewById(R.id.text1); 
     text.setText(String.format("Selected %s for item %s", menuItemName, songName)); 
      startActivity(new Intent(this,test4contextmenu.class)); 

     return true; 
    }

     { 
     mnu1.setAlphabeticShortcut(‘a’); 
     mnu1.setIcon(R.drawable.icon);
