Question

我可以从图库中选择一张图片，裁剪并将其设为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。我想在取消裁剪时收到实际的位图。我怎么能这样做？

Answer 1

我找到了解决方案：

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

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == AppConstant.PICK_PROFILE_PIC) {
        // getActivity();
        if (resultCode == Activity.RESULT_OK && data != null) {
            selectedImage = data.getData();
            String[] filePathColumn = {MediaStore.Images.Media.DATA};

            Cursor cursor = getContentResolver().query(
                    selectedImage, filePathColumn, null, null, null);

            // some devices (OS versions return an URI of com.android
            // instead of com.google.android
            if (selectedImage.toString().startsWith(
                    "content://com.android.gallery3d.provider")) {
                // use the com.google provider, not the com.android
                // provider.
                selectedImage = Uri.parse(selectedImage.toString().replace(

    } else if (requestCode == AppConstant.CLICK_IMAGE) {
        File f = new File(Environment.getExternalStorageDirectory()

       Toast.makeText(RegistrationActivity.this, mPicturePath + "", Toast.LENGTH_LONG).show();

    } else if (requestCode == AppConstant.CROP_IMAGE && resultCode != RESULT_CANCELED) {
        // get the returned data
