在抽屉布局中使用 Glide 从 Url 使用 CircularImage 视图时应用程序崩溃
App Crashes when using CircularImage view from Url using Glide in Drawer Layout
我正在使用 Github library 中的 Glide 和 CircularImageview 来获取图像 URL 并将其显示到 Drawerlayout 的 ImageView.它工作正常并加载了图像。当我打开应用程序并在未打开 NavigationDrawer 的情况下关闭应用程序时，它不会产生任何错误，但是当我打开应用程序并打开 DrawerLayout，然后按后退按钮关闭应用程序时，它崩溃了以下错误：

<attr name="civ_border_overlay" format="boolean" />
<attr name="civ_fill_color" format="color" />
</declare-styleable>
</resources>
在布局文件中使用它
<YOUR_PACKAGE.CircleImageView
android:id="@+id/imageUser"
android:layout_width="120dp"
android:layout_height="120dp"
android:layout_marginTop="20dp"
/>
请改用 CircleImageView library。
这是我在许多项目中看到的用于圆形图像的库
这应该可以解决您的问题
这是一个例子
<de.hdodenhof.circleimageview.CircleImageView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/profile_image"
android:layout_width="96dp"
android:layout_height="96dp"

app:civ_border_color="#FF000000"/>

此外，这些是 XML
的属性<?xml version="1.0" encoding="utf-8"?>
<resources>
<declare-styleable name="CircleImageView">
<attr name="civ_border_width" format="dimension" />
<attr name="civ_border_color" format="color" />
<attr name="civ_border_overlay" format="boolean" />
<attr name="civ_fill_color" format="color" />
</declare-styleable>
</resources>
在布局文件中使用它
<YOUR_PACKAGE.CircleImageView
android:id="@+id/imageUser"
android:layout_width="120dp"
android:layout_height="120dp"
android:layout_marginTop="20dp"
/>
请改用 CircleImageView library。 这是我在许多项目中看到的用于圆形图像的库 这应该可以解决您的问题
这是一个例子
<de.hdodenhof.circleimageview.CircleImageView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/profile_image"
android:layout_width="96dp"
android:layout_height="96dp"
android:src="@drawable/profile"
app:civ_border_width="2dp"
app:civ_border_color="#FF000000"/>
