デフォルトの画像は最初に取り込まれた画像に置き換えられません

私のアプリでは、画像をキャプチャして2番目のアクティビティで設定してから、いくつかの操作を行った後にサーバにアップロードします。最初のアクティビティでイメージビューにイメージを表示し、それ以外の場合はデフォルトイメージを表示します。イメージをキャプチャしてイメージをアップロードしようとすると、そのIDのイメージがサーバーに既に存在する場合、キャプチャされたイメージは最初のアクティビティのイメージビューで更新されます。そのIDのイメージがない場合、キャプチャされた画像は表示されません。同じIDにログインすると、2度目に表示されます。 2番目のアクティビティから戻ると、最初のアクティビティをリフレッシュする方法。ここに私のコードです：デフォルトの画像は最初に取り込まれた画像に置き換えられません

@Override

    if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {

私はこれを試しました。キャプチャされたイメージを表示しています。しかし、私はサーバーにアップロードされている切り抜かれたイメージの結果を表示したいと思います。 – Amshu

あなたがコードを使って作物をするのではなく、 'Image'アクティビティの不完全なコードを追加してください。 ....そしてあなたはどこで作物をしていますか？ –

私は持っていません... – Amshu

我々は画像をトリミングimage.Afterをトリミングするためにサードパーティのライブラリを使用していた、我々はcrop.Hereを処理するために、以前の活動への意図を渡すコードであり、

if (resultCode == Activity.RESULT_OK) { 
     Uri croppedUri = Crop.getOutput(result); 
     File outPutFile = new File(croppedUri.getPath()); 
     mImagePath = outPutFile.getAbsolutePath(); 
     mCurrentPhotoPath = mImagePath; 
     Point size = Utility.getDisplayPoint(mActivity); 
     int width = size.x; 
     int height = (width * 9)/16; 
     Logger.i("height", height + ""); 
     Logger.i("cropped path", outPutFile.getAbsolutePath() + ""); 
     changeBeamPosterDimension(height, width); 
     setPic(mImagePath);
