Android Canceling Crop 不返回活动结果答案

【问题标题】：Android Canceling Crop does not return activity resultAndroid Canceling Crop 不返回活动结果

【问题描述】：

我可以从图库中挑选一张图片，将其裁剪并获取为bundle。我以这种方式检索它：

if (resultCode == Activity.RESULT_OK) {
      if (requestCode == SELECT_IMAGE || requestCode == SELECT_LANDSCAPE_IMAGE) {
           Bundle extras = data.getExtras();
           Bitmap photo = extras.getParcelable("data");
                .........................
      }
}

一切正常。但是当我取消裁剪时，没有收到任何捆绑包。当我取消裁剪时，我想收到实际的位图。我该怎么做？

【问题讨论】：

如果他们取消了，它可能不会返回 RESULT_OK。

【解决方案1】：

我找到了解决办法：

if (requestCode == CROP_FROM_CAMERA && resultcode == RESULT_CANCELED {
  // crop was cancelled
}
