如何在Android中使用不同参数在同一活动中裁剪两张不同的图像？

我正在使用SoundCloud的Crop库。选择一个图像视图，选择图像，裁剪并在图像显示结果工作正常。但现在我试图用两种不同规格的不同图像浏览。我没有收到任何错误，也没有看到任何结果。以下是我所尝试的：如何在Android中使用不同参数在同一活动中裁剪两张不同的图像？

//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(); 
    } 
}

我只是想知道，如果你想一次或一个接一个地裁剪两个图像????用不同的onclick听众？ @Steve C –

@SnehalGongle一个接一个 –

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拣选和裁剪（总共4个请求代码），因为您需要以不同方式处理它们，并更新onActivityResult()，handleCrop()以反映这一点。

我认为，但裁剪库中的类“裁切”会为返回的裁剪图像默认调用REQUEST_CROP requestCode。我不知道如何区分两者，如果他们需要不同。 –

该库指出您可以为初始“选择图像”请求传递一个自定义requestCode，但是如何从同一活动中获取两个不同作物的返回图像？你认为我可以修改Crop类来调用两个不同的作物请求代码吗？ –

我可以看到Crop有许多其#start（）方法的变体，它需要上下文，片段和自定义请求代码。我认为这就是你需要的。 – Vibin

列表项

下面是使用REST客户端与改造库的图像选择的完整代码裁剪和上传到服务器下面几个变量使用额外的为我的使用请忽略他们

而且我使用内部格拉德尔这些库

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'

而且内部Mainfrest我已经specifed此作为<activity android:name="com.theartofdev.edmodo.cropper.CropImageActivity" android:screenOrientation="portrait" />

side2Image.setOnClickListener(new View.OnClickListener() {

    savedFileDestination = new File(imagePath, name + ".jpg"); 

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