如何在Android中使用不同的参数在同一活动中裁剪两个不同的图像？

Question

我正在使用 SoundCloud 的这个Crop库。 选择一个图像视图，选择图像，裁剪并在图像视图中显示结果工作正常。 但现在我试图用两个不同规格的不同图像视图来做到这一点。 我没有收到任何错误，也没有看到任何结果。 这是我尝试过的：

//My click listeners
regCoverPhoto.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Crop.pickImage(getActivity(), EditProfileDialog.this, REQUEST_CODE_COVER);
    }
});
regUserProfile.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Crop.pickImage(getActivity(), EditProfileDialog.this, REQUEST_CODE_PROFILE);
    }
});
//Handling the result
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_CODE_PROFILE && resultCode == Activity.RESULT_OK) {
        beginCropProfile(data.getData());
    }else if(requestCode == REQUEST_CODE_COVER && resultCode == Activity.RESULT_OK){
        beginCropCover(data.getData());
    } else if (requestCode == Crop.REQUEST_CROP) {
        handleCrop(requestCode, resultCode, data);
    }
}

private void beginCropProfile(Uri source) {
    Uri destination = Uri.fromFile(new File(getActivity().getCacheDir(), "cropped"));
    Crop.of(source, destination).withAspect(ASPECT_X, ASPECT_Y).start(getActivity(), EditProfileDialog.this, REQUEST_CODE_COVER);
}

private void beginCropCover(Uri source) {
    Uri destination = Uri.fromFile(new File(getActivity().getCacheDir(), "cropped"));
    Crop.of(source, destination).asSquare().start(getActivity(), EditProfileDialog.this, REQUEST_CODE_PROFILE);
}

private void handleCrop(int requestCode, int resultCode, Intent result) {
    if (requestCode == REQUEST_CODE_COVER && resultCode == Activity.RESULT_OK) {
        regCoverPhoto.setImageURI(Crop.getOutput(result));

        mCoverPhotoUri = Crop.getOutput(result);
        uploadCoverToStorage();

        Log.d(TAG,"ResultCover: " + Crop.getOutput(result).toString());
    }else if(requestCode == REQUEST_CODE_PROFILE && resultCode == Activity.RESULT_OK){
        regUserProfile.setImageURI(Crop.getOutput(result));
        mProfilePhotoUri = Crop.getOutput(result);
        uploadProfileToStorage();
        Log.d(TAG,"ResultProfile: " + Crop.getOutput(result).toString());
    } else if (resultCode == Crop.RESULT_ERROR) {
        Snackbar.make(getView(), Crop.getError(result).getMessage(), Snackbar.LENGTH_LONG).show();
    }
}

Answer 1

我没有特别使用过这个库，但自定义请求代码似乎是问题所在。

使用不同的请求代码进行采摘和裁剪（总共 4 个请求代码），因为您需要以不同的方式处理它们，并更新onActivityResult() 、 handleCrop()以反映这一点。

1. 列表项

这是使用带有改造库的rest客户端裁剪和上传到服务器的图像选择的完整代码这里使用了一些额外的变量，因为我的使用请忽略它们

我也在gradel中使用这些库

 compile 'com.squareup.retrofit2:retrofit:2.3.0'
compile 'com.theartofdev.edmodo:android-image-cropper:2.4.+'
compile 'com.squareup.retrofit:retrofit:1.6.1'

在 Mainfrest 中，我将其指定为<activity android:name="com.theartofdev.edmodo.cropper.CropImageActivity" android:screenOrientation="portrait" />

side2Image.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
    image_name = "image_side_2";
    image_number_5 = "image_side_2";
    imagePath = Environment.getExternalStorageDirectory().toString();
    new File(imagePath).mkdir();

    SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMddhhmmss");
    String name = dateFormat.format(new Date());
    savedFileDestination = new File(imagePath, name + ".jpg");

    CropImage.activity(Uri.fromFile(savedFileDestination));
    CropImage.startPickImageActivity(TradeAddProduct.this);
}

backImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
    image_name = "image_back";
    image_number_6 = "image_back";
    imagePath = Environment.getExternalStorageDirectory().toString();
    new File(imagePath).mkdir();

    SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMddhhmmss");
    String name = dateFormat.format(new Date());
    savedFileDestination = new File(imagePath, name + ".jpg");

    CropImage.activity(Uri.fromFile(savedFileDestination));
    CropImage.startPickImageActivity(TradeAddProduct.this);
}

@Override
@SuppressLint("NewApi")
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == CropImage.PICK_IMAGE_CHOOSER_REQUEST_CODE && resultCode == Activity.RESULT_OK) {
        imageUri = CropImage.getPickImageResultUri(this, data);

        // For API >= 23 we need to check specifically that we have permissions to read external storage.
        if (CropImage.isReadExternalStoragePermissionsRequired(this, imageUri)) {
            // request permissions and handle the result in onRequestPermissionsResult()
            mCropImageUri = imageUri;
            requestPermissions(new String[]{android.Manifest.permission.READ_EXTERNAL_STORAGE}, 0);
        } else {
            // no permissions required or already grunted, can start crop image activity
            startCropImageActivity(imageUri);
        }
    }

    // handle result of CropImageActivity
    if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
        CropImage.ActivityResult result = CropImage.getActivityResult(data);
        if (resultCode == RESULT_OK) {

            if (image_name.equals("image_front")) {
                image.setImageURI(result.getUri());
            } else if (image_name.equals("image_top")) {
                topImage.setImageURI(result.getUri());
            } else if (image_name.equals("image_bottom")) {
                bottomImage.setImageURI(result.getUri());
            } else if (image_name.equals("image_side_1")) {
                side1Image.setImageURI(result.getUri());
            } else if (image_name.equals("image_side_2")) {
                side2Image.setImageURI(result.getUri());
            } else if (image_name.equals("image_back")) {
                backImage.setImageURI(result.getUri());
            }

            cropped = result.getUri();
            File path = getExternalCacheDir();
            new File(String.valueOf(path)).mkdir();

            imagePath = Environment.getExternalStorageDirectory().toString();
