こんにちはカレン、私が表示しようとしている 画像は「contentLayout」です。私は新しいフォルダ内のcontentLayoutの中にイメージを置いて、保存されたイメージが新しい名前を取得し続けるようにforループを追加しました。 pic + i（増分値）+ .png。 –

+0

onLikesは10種類の画像に使用されます。画像が好きであるか右にスワイプされている場合、画像は自分のSDカードにpic- + i + .pngの名前で保存されます すべての画像が異なる名前になり、1を超える保存が可能です画像。 （私もタイムスタンプでこれを試して、それは正常に動作します）。 もっとコードを表示しますが、実際に表示されている画像（保存したい画像）ではなく、表示される画像が保存されるようなものを押した場合を除き、すべて正常に機能します –

あなたのコードを誤解して申し訳ありません。私は今理解し、私の長年の無関係なコメントを削除しました！より多くのコードを投稿してくれてありがとうございました。私の答えを見て、それが助けてくれたらお知らせください:) –

私はあなたが保存しようとしている画像が原因ライブラリコードにonSwipe時に除去なっていると信じて：私が試したが、私は同じ結果を得続ける（私がやっていること以下のコメントを読んで、コード。あなたがコードをに移動する前に、のonLikeが呼び出される必要があると思います。

あなたはまた、むしろここに指名手配ImageViewのよりも、全体のレイアウトのキャッシュからビットマップを取得しようとしている：

bm=contentLayout.getDrawingCache();

ビューとして現在のカードビューを取得したいと思います、そして、あなたのコードの私の理解から、期待されるビットマップを含むあなたの実際のImageViewののIDはR.id.imgMealsですので、私のライン交換をお勧め：

bm=contentLayout.getDrawingCache();

のWi次番目：

ImageView imageView = (ImageView) cardView.findViewById(R.id.imgMeals); 
BitmapDrawable drawable = (BitmapDrawable) imageView.getDrawable(); 
Bitmap bm = drawable.getBitmap();

移動私は//ここをマークしているとあなたは、それを持っているところから、以下のコードのすべての !!コードの次の部分に（または、新しいメソッドに移動して、ここでメソッドを呼び出す方がよい）。

// If the imageview of like is clicked 
case R.id.imgLike: { 
    // HERE!! 

    // The imageview in the contentlayout will be swiped to the right 
    mSwipeView.likeCard(); 
    break; 
}

これは私にはコードですが、私は上記の言及の変更を含む移動：

View cardView = mSwipeView.getChildAt(mSwipeView.getChildCount() - 1); 
    ImageView imageView = (ImageView) cardView.findViewById(R.id.imgMeals); 
    BitmapDrawable drawable = (BitmapDrawable) imageView.getDrawable(); 
    Bitmap bm = drawable.getBitmap(); 

    OutputStream fOut = null; 
    try { 
     // Save on my sd card 
     File root = new File(Environment.getExternalStorageDirectory() 
       // Making a folder name Food Inspiration 
       + File.separator + "Food Inspiration" + File.separator); 
     root.mkdirs(); 
     File sdImageMainDirectory = null; 

     // Loop for having a different name for every image 
     int i = 0; 
     do { 
      sdImageMainDirectory = new File(root, "pic-" + i + ".png"); 
      i++; 
     } while (sdImageMainDirectory.exists()); 
     fOut = new FileOutputStream(sdImageMainDirectory); 

     // Updates the gallery of your phone with the folder and the "liked" images in it 
     MediaScannerConnection.scanFile(this, new String[] { sdImageMainDirectory.getAbsolutePath() }, null, null); 

     // If something goes wrong 
    } catch (Exception e) { 
     Toast.makeText(this, "Error occured. Please try again later.", 
       Toast.LENGTH_SHORT).show(); 
    } 
    // Compresses the actual bitmap image 
    try { 
     bm.compress(Bitmap.CompressFormat.PNG, 100, fOut); 
     fOut.flush(); 
     fOut.close(); 
    } catch (Exception e){}

私はあなたのコードを実装しようとしました。しかし、カードビューは、 ImageView imageView =（ImageView）cardView.findViewById（R.id.imgMeals）; が赤く表示されます。これは初期化されていないためですか？もしそうなら、私はこれをどのように初期化すべきですか？ –

申し分なく、 はい、本当にライブラリを使用しています。私は図書館で自分の投稿を更新しました。 onLikesまたはaddCardを検索すると、その動作を確認できます。 ご不明な点がありましたら、できるだけ早く返信いたします:) –

申し訳ありません！ 私はベストを尽くします！あなたの時間と労力に感謝します:) 私は私が試したもので戻ってきます、そして、もし私が正しい方向に向かっているかどうかを私に教えてください。 –
