グライド：どのようにキャッシュから画像を読み込むからグライドを停止する代わりに、サーバからロードするたび

Question

は、私は可能なすべてのものを試してみましたが、私のJSONが

MY Androidアプリを更新されるたびに滑空するイメージを更新する方法を見つけ出すことを試みることができませんでしたそれだけでcache.Itからイメージをロードし、その後initally FIRSTTIME用グライドを使用して、JSONから画像をロードし、私はdiskCacheStrategy（DiskCacheStrategy.NONE）を使用してみました私は、アプリを削除し、それを

を再インストールまで、サーバー上で更新されている負荷の画像をdoesnotと.skipMemoryCache（真）しかし何も起こらなかった

Glide.with(mContext).load(image.getMedium()) 
       .thumbnail(0.5f) 
       .crossFade() 
       .diskCacheStrategy(DiskCacheStrategy.NONE) 
       .skipMemoryCache(true) 
       .into(holder.thumbnail);

のコードですこの問題

Answer 1

まあ、誰もが感謝の助け:)

ための多くは私が問題を引き起こしていたボレーライブラリのキャッシュを無効にすることで、この問題を解決しますが、とにかく助けてくれてありがとう:)

//disabling caching for url 
     AppController.getInstance().getRequestQueue().getCache().remove(url); 

Answer 2

Signatureを使用すると、キャッシュを無効にしてネットワークから画像を読み込むことができます。それはあなたがまた

をキャッシュにグライドのドキュメントを1としてSignatures を設定してみてください可能性がありたび

Answer 3

この

を試してみてくださいネットワークからイメージをロードするようにするだけの署名に new StringSignature(System.currentTimeMillis()+"")を渡す

Glide.with(Fragment/context) 
.load(imagePath) 
.signature(new StringSignature(yourVersion)) 
.into(ImageView); 

をお試しください

Glide.with(context) 
    .load(url) . 
    signature(new StringSignature(System.currentTimeMillis())) 
.into(imageView);
