在片段裏面的ListView的上下文菜單

我到處搜索，我也試過每一個代碼，我看着，但不幸的是他們都沒有工作。 :(我已經添加了registerForContextMenu（）方法，但它仍然不會彈出菜單，當我點擊我的列表中的一個項目時，請幫助我已經瘋了。（這是我到目前爲止...在片段裏面的ListView的上下文菜單

你想打開一個菜單中選擇它當用戶點擊ListView項目？

因此，您可以簡單地設置OnLongClickListener（或簡單的OnClickListener取決於你正在上的項目試圖做的），打開一個：

android.support.v7.widget.PopupMenu：

@Override 
public boolean onLongClick(View v) { 
    PopupMenu menu = new PopupMenu(YourActivity.this, listItem); 
    menu.getMenuInflater().inflate(R.menu.your_menu_file, menu.getMenu()); 
    menu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() { 
     @Override 
     public boolean onMenuItemClick(MenuItem item) { 
     switch (item.getItemId()) { 
      case R.id.your_first_menu_item: 
      // do something 
      break; 
     } 
     return false; 
     } 
    }); 
    menu.show(); 
    return false; 
}

原諒我的清白......這是如此尷尬。其實際工作。我只需要長時間點擊它。

XD我很抱歉浪費時間。歡呼每個人。
