Android 怎样更改Glide的缓存路径

• 使用GlideBuilder的实现类来指定Glide缓存

public class GlideCache implements GlideModule {

    @Override
    public void applyOptions(Context context, GlideBuilder builder) {
        //设置图片的显示格式ARGB_8888(指图片大小为32bit)
        builder.setDecodeFormat(DecodeFormat.PREFER_ARGB_8888);
        //设置缓存目录(都可以自定义的)
        File storageDirectory = Environment.getExternalStorageDirectory();
        String downloadDirectoryPath=storageDirectory+"/GlideCache";

    //设置缓存的大小为100M
    int cacheSize = 100*1000*1000;     
   builder.setDiskCache(  new DiskLruCacheFactory(downloadDirectoryPath, cacheSize)    
    );   
 }   
 
      @Override  
  public void registerComponents(Context context, Glide glide)
 {   }
}

• 在AndroidManifest中配置GlideCache，

<meta-data android:name="包名.GlideCache"
    android:value="GlideModule"/>
