滑行.缓存到外部存储(SD卡)

Question

我使用Glide在我的Android应用程序中加载图像.
3.5更新后,开发人员提供了GlideModule接口.
根据这篇文章(Disk Cache)我可以设置缓存目录,使用setDiskCache方法和ExternalCacheDiskCacheFactory.
但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.

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

滑行使用:

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

GlideBuilder使用值设置setDiskCache 您可以将ExternalStorageDirectory设置为缓存目录.

  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

希望对你有所帮助.
