当我使用Glide在ImageView中显示图像时，背景中添加了灰色。我尝试在我的xml中的ImageView中将背景颜色设置为透明甚至白色文件..
但它仍然不起作用......我在各种 Activity 中显示的每张图像都会发生这种情况。
下面是在 iPhone 和 Android Oreo 中显示的同一图像的屏幕截图。
下面是我的 xml 文件:

最佳答案
解决方案:
无论您将 ImageView 放置在哪个父布局中，如<LinearLayout>或<RelativeLayout>或<ConstraintLayout> ，它们都有一个默认颜色代码 #FAFAFA这不完全是白色，这是可能的原因之一
您可能已经知道白色的颜色代码是 #FFFFFF .
所以你的答案在于你的布局，设置你的父布局的背景颜色，其中你的ImageView居住为白色 #FFFFFF如下图:
<LinearLayout
android:id="@+id/bklayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingBottom="28dp"
android:paddingTop="8dp"
android:background="#FFFFFF">
<ImageView
android:id="@+id/bkbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</LinearLayout>
更新:在 Glide 中添加以下行如上所述Here
.dontTransform()
.diskCacheStrategy(DiskCacheStrategy.SOURCE)
尝试一下，我希望这就是问题所在。
关于android - 当它有白色的android时，为什么图像显示为浅灰色背景？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/53001993/
