Glide 无法下载图片到 ImageView

Question

我从 iOS 切换到 Android 并尝试通过 URL 下载图像，对于这个问题，我发现很多尝试图像下载的开发人员更喜欢使用 Glide 库，但我看到了错误，但我可以' . 请查看我的代码并说出我做错了什么？

JPEG 和 PNG 格式会发生此错误。 滑翔版 4.12.0

代码：

val urlJpg = "http://developer.alexanderklimov.ru/android/images/android_cat.jpg"
lateinit var img: ImageView

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

img = findViewById(R.id.imageView)

Glide.with(this) //1
    .load(urlJpg)
    .placeholder(R.drawable.ic_launcher_background)
    .error(R.drawable.ic_launcher_foreground)
    .into(img)
}

Answer 1

我检查了日志并尝试使用这篇Glide 显示错误的帖子解决了我的问题：未能找到 GeneratedAppGlideModule

上面的示例适用于某些情况，但对于我的问题解决方案，只需在 Manifest 文件中添加允许清除 HTTP 流量。

android:usesCleartextTraffic="true"

我所有的清单文件：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.testglideandpicasso">
    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:usesCleartextTraffic="true"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.TestGlideAndPicasso">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Answer 2

在清单中添加网络安全配置 xml 文件

res/xml/network_security_config.xml：

• 在资源 xml 文件夹中创建 Network security config.xml。

 <?xml version="1.0" encoding="utf-8"?> <network-security-config> <domain-config cleartextTrafficPermitted="true"> <domain includeSubdomains="true">developer.alexanderklimov.ru/</domain> </domain-config> </network-security-config>

• 在清单中添加 Network security config.xml，如下所示。

 <application android:name=".MyApplication" android:networkSecurityConfig="@xml/network_security_config"... />

Answer 3

我认为您在 AndroidManifest.xml 中缺少INTERNET权限。 请在 AndroidManifest.xml 文件中的应用程序元素之前定义权限。

<uses-permission android:name="android.permission.INTERNET" />

Any internet request on Android platform must have this permission, for more permissions, please check android developer documentation: https://developer.android.com/reference/android/Manifest.permission?hl=en

祝您的 Android 开发之旅愉快！
