我的用戶界面不工作（按鈕）

我有一個應用程序，突然我的用戶界面停止工作分享按鈕的作品，也是選項菜單，但由於一些奇怪的原因我的按鈕停止工作，他們不點擊或做任何事情。是否可能是由於我的OptionsMenu類的擴展？我不知道爲什麼？這是否經常發生，我嘗試新建立我的項目，但沒有用。我這裏有我的MainActivity類別我的用戶界面不工作（按鈕）

這裏是我在哪裏延伸，我沒有使用AppCompatActivity活動注意OptionsMenu類。

      return super.onOptionsItemSelected(item); 
      // TODO: Implement this method 
    } 
    return super.onOptionsItemSelected(item);

如果需要，我可以張貼更多的代碼。並且將重新編輯，如果不夠清晰謝謝

我看不到你設置onClickListener的大部分按鈕。它是否在佈局XML中設置？如果不是，那可能是問題所在。 –

是的，所有的按鈕都是在使用OnClick的XML佈局中設置的，但它突然停止。 –

OnItemClickListener不工作，我知道代碼是正確的（不是粗魯，我知道我是一個新手），但它現在工作之前，現在沒有什麼沒有點擊或什麼????? –

粘貼您的佈局XML。我想這是由某些東西（也許是一些父視圖）導致的焦點中斷，所以子視圖按鈕無法獲得焦點。

我已經發布了佈局XML謝謝你的幫助BTW –
