如果未選擇圖像，則顯示錯誤提示

[英]Show error note if image not selected android

 原文  2017-09-22 16:06:13  9   1    java/ android/ dialog/ gallery

問題描述

這是我下面的完整代碼。 我正在編碼一個可以從畫廊或任何地方選擇圖像的android應用程序，並通過php將其上傳到Mysql服務器，但是如果未選擇圖像並且按下了上傳按鈕，則應用程序崩潰，因此我想實現顯示錯誤對話框的功能/如果未從圖庫中選擇圖像，則警告對話框已在EditText中實現，但無法在Image中實現。 下面是我的代碼
