畢加索不顯示來自firebase的圖像
[英]picasso not displaying image from firebase
問題描述
鏈接到數據庫結構我最近在我的應用程序中添加了一個功能，它允許用戶上傳個人資料圖片，該圖像存儲在 firebase 中，然后在應用程序中顯示給用戶。 圖像成功存儲在 firebase 中，但是當要顯示圖像時，它只會刪除默認顯示圖像並且不顯示任何內容。

使用最新版本的畢加索作為 -
implementation 'com.squareup.picasso:picasso:2.71828'
Picasso.get().load(url).resize(100,100).centerCrop().into(imageView);
