在 onActivityResult 中收到两个 requestCode == UCrop.REQUEST_CROP？

Question

我正在使用uCrop 库来执行图像裁剪。

我需要在同一个活动中剪切两个不同的图像。但是使用我的代码，返回会陷入一个循环。

我怎样才能把这个回报分开，独立对待？

代码：

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

        if (resultCode == RESULT_OK) {

            if (requestCode == UCrop.RESULT_ERROR) {
                Toast.makeText(this, "uCrop error", Toast.LENGTH_SHORT).show();
                return;
            }

            if (requestCode == UCrop.REQUEST_CROP) {

                mSelectImage.setImageResource(0);
                final Uri imgUri = UCrop.getOutput(data);
                mResultUri = imgUri;
                mSelectImage.setImageURI(mResultUri);
                temDadosSalvar = true;

                Toast.makeText(this, "Cortada", Toast.LENGTH_SHORT).show();
                return;
            }


            if (requestCode == CAMERA_REQUEST_CODE && resultCode == RESULT_OK) {

                mImageUri = data.getData();
                if (mImageUri == null) {
                    mProgress.dismiss();
                    return;
                } else {
                    File tempCropped = new File(getCacheDir(), "tempImgCropped.png");
                    Uri destinationUri = Uri.fromFile(tempCropped);
                    UCrop uCrop = UCrop.of(mImageUri, destinationUri);

                    uCrop = advancedConfig(uCrop);
                    uCrop.start(this);
                }
            }

            if (requestCode == CAMERA_REQUEST_CODE_CAPA && resultCode == RESULT_OK) {


                mImageUri = data.getData();
                if (mImageUri == null) {
                    mProgress.dismiss();
                    return;
                } else {
                    File tempCropped = new File(getCacheDir(), "tempImgCropped.png");
                    Uri destinationUri = Uri.fromFile(tempCropped);
                    UCrop uCrop = UCrop.of(mImageUri, destinationUri);


                    uCrop = advancedConfig(uCrop);
                    uCrop.start(this);
                }
            }
        }
    }

您可以创建两个类变量来识别正在裁剪的图像。

private Uri mDestinationCapa;
private Uri mDestinationCamera;

 if (requestCode == CAMERA_REQUEST_CODE && resultCode == RESULT_OK) {
            mImageUri = data.getData();
            if (mImageUri == null) {
              ...
            } else {
                File tempCropped = new File(getCacheDir(), "tempImgCropped.png");
                mDestinationCamera= Uri.fromFile(tempCropped);
                ...
            }
        }

        if (requestCode == CAMERA_REQUEST_CODE_CAPA && resultCode == RESULT_OK) {
            mImageUri = data.getData();
            if (mImageUri == null) {
             ...
            } else {
                File tempCropped = new File(getCacheDir(), "tempImgCropped.png");
                mDestinationCapa = Uri.fromFile(tempCropped);
                ...
            }
        }

在 ActivityResult 上，您可以将结果 Uri 与本地 Uris 进行比较：

if (requestCode == UCrop.REQUEST_CROP) {

        final Uri imgUri = UCrop.getOutput(data);
        if(mDestinationCamera != null && imgUri.equals(mDestinationCamera)){
            //save camera cropped image 

        }if(mDestinationCamera != null && imgUri.equals(mDestinationCamera)){
            //save capa cropped image
        }
        return;
    }
