代碼中的錯誤按鈕的按鈕完全沒有任何東西

我有一個問題，我不知道哪個是一個錯誤，當我按下添加照片按鈕或發送按鈕根本沒有發生，我沒有得到任何錯誤，第一個按鈕應該打開我的照片，第二應該發送到RecyclerView在fragament我給我的代碼代碼中的錯誤按鈕的按鈕完全沒有任何東西

對不起，我的英語使用谷歌翻譯

你沒有在任何'Button'上調用'setOnClickListener（this）'。 –

在代碼 – warlock

@dskato中沒有使用setOnClickLisnter（），只需將它添加到已初始化小部件的代碼中即可。 mPostImageView.setOnClickListener（this）; selectFotoButton.setOnClickListener（this）; sendPostButton.setOnClickListener（this）; – Geek

嘗試在按鈕單擊上顯示任何烤麪包。如果吐司出現，那麼您的點擊事件正在工作，如果吐司沒有顯示，那麼您的按鈕點擊不起作用。
