public class MyApp extends Application {
    @Override
    public void onCreate() {
        super.onCreate();

        //設定自定義快取地址
        DiskCacheConfig images = DiskCacheConfig.newBuilder(this)
                .setBaseDirectoryName("images")//設定資料夾名
                .setBaseDirectoryPath(Environment.getDataDirectory())//設定快取路徑(sd)
                .build();

        ImagePipelineConfig build = ImagePipelineConfig.newBuilder(this)
                .setMainDiskCacheConfig(images)
                .build();

        Fresco.initialize(this,build);
    }
}
 

如果想在其他路徑需要把setBaseDirectoryPath方法換成下面的方法(按照需求選一個)

.setBaseDirectoryPath(Environment.getDataDirectory())//設定快取路徑(sd)
 .setBaseDirectoryPath(Environment.getExternalStorageState(file))//自定義路徑
