為什么會出現此錯誤 任何人都知道

UnknownException：（無法啟動活動 ComponentInfo{com.gauravkhannamarketeer.lordshivahdwallpapers/com.gauravkhannamarketeer.lordshivahdwallpapers.activity.ImageLodingValues}：android.view.InflateException：二進制 XML 文件第 2 行：錯誤膨脹類）

錯誤是由 CrashReports 報告的錯誤進來

Divece OS：4.4.4 設備型號：紅米2(Redmi 2) 設備子型號：2014818

提前致謝

Answer 1

首先來自您的錯誤日志

android.view.InflateException：二進制 XML 文件第 2 行：錯誤膨脹類）

您似乎對 ConstraintLayout 有某種問題。 但是你已經正確地包含了庫，以及在 xml 中正確提到的約束布局。

所以這段代碼可能有一個問題。

 android:background="@drawable/mahadev_imagesbg"

在運行時，Android 根據需要（基於屏幕大小和分辨率）調整圖像大小。 它使用 Bitmap 進行內部調整大小。 這是非常內存密集的。 所以你的設備紅米 2（紅米 2）有內存問題，它正在生成錯誤。

因此，嘗試一種解決方案：將此（mahadev_imagesbg）圖像復制到 drawable-ldpi、mdpi、hdpi 文件夾，然后使用該設備再次測試。 或者嘗試使用較低分辨率的圖像。 也許它會解決你的問題。
