Android Studio中使用Glide加载字符串预览图至ImageView的问题

你之前的Glide代码核心错误是把ImageView对象（previewUrl）传给了load()方法，而load()需要的是图片地址字符串image.previewUrl；另外不要手动实例化Activity()，直接用当前Activity的上下文this即可。

正确的Glide加载代码 #

替换你注释掉的所有尝试代码，用这一行即可：

Glide.with(this).load(image.previewUrl).into(previewUrl)

额外注意事项 #

• 确认ImageModel中的previewUrl是有效的网络图片地址或本地文件路径字符串
• 如果加载的是网络图片，必须在AndroidManifest.xml中添加网络权限：

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

• 确保项目已正确引入Glide依赖（以最新稳定版本为例）：

  implementation 'com.github.bumptech.glide:glide:4.16.0'
  annotationProcessor 'com.github.bumptech.glide:compiler:4.16.0'
  

修正后的完整代码片段 #

class ImageInformation : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_image_information)

        val image = intent.getParcelableExtra<ImageModel>("image")
        if (image != null){
            val downloadUrl: TextView = findViewById(R.id.downloadUrla)
            val previewUrl : ImageView = findViewById(R.id.previewUrls)
            val id: TextView = findViewById(R.id.idsa)
            val filename: TextView = findViewById(R.id.fileNamea)
            val filesize: TextView = findViewById(R.id.filesizea)
            val contentType: TextView = findViewById(R.id.contentTypea)
            val createdBy: TextView = findViewById(R.id.createdBya)
            val createdTimestamp: TextView = findViewById(R.id.createdTimestampa)
            val creationSource: TextView = findViewById(R.id.creationSourcea)
            val domainIdentityType: TextView = findViewById(R.id.domainIdentityTypea)
            val domainIdentityValue: TextView = findViewById(R.id.domainIdentityValuea)
            val tags: TextView = findViewById(R.id.tagsa)
            val description: TextView = findViewById(R.id.descriptiona)

            downloadUrl.text = image.downloadUrl
            // 正确加载图片的代码
            Glide.with(this).load(image.previewUrl).into(previewUrl)

            id.text = image.id
            filename.text = image.fileName
            filesize.text = image.filesize.toString()
            contentType.text = image.contentType
            createdBy.text = image.createdBy
            createdTimestamp.text = image.createdTimestamp
            creationSource.text = image.creationSource
            domainIdentityType.text = image.domainIdentityType
            domainIdentityValue.text = image.domainIdentityValue
            tags.text = image.tags.toString()
            description.text = image.description
        }
    }
}
