滑行.缓存到外部存储(SD卡) [英] Glide. Cache to External Storage (SD card)

问题描述

我使用 Glide 在我的android应用程序中加载图片.
在3.5更新之后，开发人员提供了 GlideModule 界面.
根据这篇文章(磁盘缓存)，我可以使用setDiskCache方法和ExternalCacheDiskCacheFactory.
但是我没有看到任何区别.所有缓存仍在默认缓存目录中的内部存储上.

I use Glide for loading Images in my android application.
After 3.5 update, developers provided GlideModule interface.
According to this article (Disk Cache) I can set cache directory, using setDiskCache method and ExternalCacheDiskCacheFactory.
But I doesn't see any difference. All cache still on the Internal storage in default cache directory.

build.gradle :

dependencies {
    ...
    compile 'com.github.bumptech.glide:glide:3.6.1'
}

Android清单:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<application ...>
<meta-data
        android:name="com.myapp.GlideConfig"
        android:value="GlideModule" />
</application>

GlideConfig.java :

public class GlideConfig implements GlideModule {
    @Override
    public void applyOptions(Context context, GlideBuilder builder) {
        String state = Environment.getExternalStorageState();
        if (Environment.MEDIA_MOUNTED.equals(state)) {
            Log.e("GlideConfig", "MEDIA_MOUNTED");
            builder.setDiskCache(
                context.getString(R.string.app_name),
                        419430400));//400Mb
            //Environment.getExternalStorageDirectory().getPath()
            // + "/"
            // + context.getString(R.string.app_name)
        }
        else {
            Log.e("GlideConfig", "!MEDIA_MOUNTED");
        }
    }

    @Override
    public void registerComponents(Context context, Glide glide) {
    }
}

proguard-rules.pro :

...
-keepnames class * com.myapp.GlideConfig

滑行:

Glide.with(context)
.load("some_url")
.dontAnimate()
.centerCrop()
.override(100, 100)
.into(holder.iv_image);

推荐答案

设置值为setDiskCache的GlideBuilder可以将ExternalStorageDirectory设置为缓存目录.

To setup GlideBuilder with value of setDiskCache You can set your ExternalStorageDirectory as a cache directory.

  if (!Glide.isSetup()) {
   GlideBuilder gb = new GlideBuilder(this);
   DiskCache dlw = DiskLruCacheWrapper.get(new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/YourCacheDirectory/"), 250 * 1024 * 1024);
   gb.setDiskCache(dlw);
   Glide.setup(gb);
}

检查无法设置GlideBuilder
