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的这个裁剪库。选择一个图像视图，切换图像，裁剪并在图像视图中显示结果可以正常工作。但是现在我正在尝试使用具有不同规格的两个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()反映这一点。

1. 列表项

这是图像选择的完整代码，使用带有改造库的 rest 客户端裁剪并上传到服务器 这里很少使用变量，供我使用，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 内部，我已将其指定为<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";

imagePath = Environment.getExternalStorageDirectory().toString();
new File(imagePath).mkdir();

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() {
