Image-Crop-Activity 不会将 Image-Uri 发送到接收活动 (Android-Image-Cropper)

Question

我正在尝试裁剪一个image(我从图库中选择或从相机中拍摄(并将其传递给另一个activity，该应该将image上传到我的Firebase存储中。

起初(没有图像裁剪(，一切都很顺利。我能够通过并上传image...但是在将图像裁剪代码添加到我的onActivityResult后，它只是在按"裁剪"后关闭图像裁剪活动并跳回我的主活动。

我已经尝试过，但我真的不知道为什么它会这样做。也许我错过了一些东西。有什么想法吗？

对于图像裁剪，我正在使用这个库：https://github.com/ArthurHub/Android-Image-Cropper

主要活动

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

        if (requestCode == 100 && resultCode == RESULT_OK) {
            CropImage.activity(mImageUri_gallery)
                    .setGuidelines(CropImageView.Guidelines.ON)
                    .start(this);
            if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
                CropImage.ActivityResult result = CropImage.getActivityResult(data);
                if (resultCode == RESULT_OK) {
                    Uri resultUriGallery = result.getUri();
                    Intent intentGallery = new Intent(MainActivity.this, ImagePostActivity.class);
                    intentGallery.putExtra("image-uri", resultUriGallery.toString());
                    startActivity(intentGallery);
                } else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
                    Exception error = result.getError();
                }
            }
        } else if (resultCode != RESULT_CANCELED && data != null) {
            if (requestCode == 200 && resultCode == RESULT_OK) {
                CropImage.activity(mImageUri_camera)
                        .setGuidelines(CropImageView.Guidelines.ON)
                        .start(this);
                if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
                    CropImage.ActivityResult result = CropImage.getActivityResult(data);
                    if (resultCode == RESULT_OK) {
                        Uri resultUriCamera = result.getUri();
                        Intent intentCamera = new Intent(MainActivity.this, ImagePostActivity.class);
                        intentCamera.putExtra("image-uri", resultUriCamera.toString());
                        startActivity(intentCamera);
                    } else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
                        Exception error = result.getError();
                    }
                }
            }
        }

    }

图像后活动

public class ImagePostActivity extends AppCompatActivity {
    public static TextView txt_btn_post;
    public static EditText mPostTitle;
    public static ImageView imagePostPreview;
    private StorageReference mStorage;
    private DatabaseReference mDatabase;
    private ProgressDialog mProgress;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_image_post);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setHomeButtonEnabled(true);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        mStorage = FirebaseStorage.getInstance().getReference();
        mDatabase = FirebaseDatabase.getInstance().getReference().child("Test_Stream_Uploads");
        mProgress = new ProgressDialog(this);
//        mPostTitle = (EditText) findViewById(R.id.mPostTitle);
        imagePostPreview = (ImageView) findViewById(R.id.imagePostPreview);
        Intent intent = getIntent();
        mImageUri_gallery = Uri.parse(intent.getStringExtra("image-uri"));
        imagePostPreview.setImageURI(mImageUri_gallery);
        mImageUri_camera = Uri.parse(intent.getStringExtra("image-uri"));
        imagePostPreview.setImageURI(mImageUri_camera);
        txt_btn_post = (TextView) findViewById(R.id.txt_btn_post);
        txt_btn_post.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                startPosting();
            }
        });

    }
    private void startPosting() {
        mProgress.setMessage("Bild wird hochgeladen...");
        mProgress.show();
        if (mImageUri_gallery != null) {
            StorageReference filepath = mStorage.child("Stream_Image").child(mImageUri_gallery.getLastPathSegment());
            filepath.putFile(mImageUri_gallery).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                @Override
                public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                    Uri downloadUrl = taskSnapshot.getDownloadUrl();
                    Intent intent = new Intent(getBaseContext(), MainActivity.class);
                    DatabaseReference newPost = mDatabase.push();
                    newPost.child("image").setValue(downloadUrl.toString());
                    mProgress.dismiss();
                    startActivity(intent);
                }
            });
        }

    }
}

我也在积极使用这个工具，实际上我并没有真正进入你的代码，但我可以给你一个例子，说明它是如何为我工作的。如果你研究它，你可以很容易地遵循并得到这个想法。它适用于您从图库中拍摄的图像。

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if(requestCode == GALLERY_REQUEST && resultCode == RESULT_OK){
        Uri imageUri = data.getData();
        CropImage.activity(imageUri)
                .setGuidelines(CropImageView.Guidelines.ON)
                .setAspectRatio(144,81)
                .start(this);
    }
    if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
        CropImage.ActivityResult result = CropImage.getActivityResult(data);
        if (resultCode == RESULT_OK) {
            Uri resultUri = result.getUri();
            ib_image.setImageURI(resultUri);
        } else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
            Exception error = result.getError();
        }
    }
}

如果你想把它应用到你刚刚从相机拍摄的图像上，你需要创建你自己的 uri，这有点长，但它在 Android 文档中进行了解释：(https://developer.android.com/training/camera/photobasics.html#TaskPhotoView(，我已经在这里的讨论中解释过：使用相机捕获图像并上传到 Firebase(onActivityResult(( 中的 Uri 为空(
