要从阿里云获取图片,可以使用阿里云OSS(对象存储服务)提供的SDK来实现。
以下是一些基本步骤:
1.在项目的build.gradle文件中添加以下依赖:
```
dependencies {
implementation 'com.aliyun.oss:aliyun-sdk-oss-android:3.4.0'
}
```
2.在代码中创建OSSClient实例:
```
String endpoint = "your_endpoint"; // OSS endpoint
String accessKeyId = "your_access_key_id"; // AccessKey ID
String accessKeySecret = "your_access_key_secret"; // Access Key Secret
String bucketName = "your_bucket_name"; // Bucket name
OSS oss = new OSSClient(getApplicationContext(), endpoint, accessKeyId, accessKeySecret);
```
3.使用OSSClient实例获取图片:
```
String objectKey = "your_object_key"; // Object key (the name of the object in OSS)
String url = oss.presignPublicObjectURL(bucketName, objectKey); // Get the public URL of the object
```
4.使用url加载图片:
```
Picasso.get().load(url).into(imageView); // Use Picasso to load the image into an ImageView
```
注意:这里使用了Picasso库来加载图片,需要在项目的build.gradle文件中添加以下依赖:
```
dependencies {
implementation 'com.squareup.picasso:picasso:2.71828'
}
```
