だから私は、ディレクトリを作成しているが、画像が添付されず、ファイルディレクトリに表示されません。私はどこから問題が発生しているのか分かりませんが、画像が処理されていないか、適切にファイルに保存されていないことが間違いないことを私は確かに知っています。
あなたが/ストレージ '別名ファイルのパスにそのファイルを持っていますか/エミュレート/ 0/Pictures/DigitalSign/imagename'？ –
まだ助けが必要な場合は、[mcve]を入力してください。特に、誰でもあなたのコードをコピーして貼り付け、コンパイルすることができます**。個人的には、いくつかのインポートステートメントを追加しても構いません。しかし、私はあなたがここで与えたコードがどのメソッドとクラスに含まれているかを推測することはできません。特にAndroidプログラミングでは、コードが実行されるライフサイクルの場所を示すため、これは重要です。 –
