在片段中裁剪图像

Question

我正在使用这个库来裁剪图像https://android-arsenal.com/details/1/3487我在尝试从片段中裁剪图像而不是从常规活动中有问题而且它不起作用，即使我做了确切的事情，这是我的onActivityResult：

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == getActivity().RESULT_OK) {
        if (requestCode == SELECT_PICTURE) {



            CropImage.activity(data.getData())
                    .setCropShape(CropImageView.CropShape.OVAL)
                    .setGuidelines(CropImageView.Guidelines.OFF)
                    .setAutoZoomEnabled(false)
                    .start(getContext(), FeedFragment.this);

        }

        if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
            CropImage.ActivityResult result = CropImage.getActivityResult(data);
            try {
                Uri resultUri = result.getUri();
                InputStream is = getActivity().getContentResolver().openInputStream(resultUri);
                Bitmap photoBitmap = BitmapFactory.decodeStream(is);
                imgButton.setImageBitmap(photoBitmap);
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            }
        }
    }
}

问题出在这一行：

  .start(getContext(), FeedFragment.this);

错误：

Failure delivering result ResultInfo{who=null, request=65537, result=-1, data=Intent { dat=content://media/external/images/media/5560 flg=0x1 (has extras) }} to activity {apps.berant.knowu/apps.berant.knowu.MainActivity}: android.content.ActivityNotFoundException: Unable to find explicit activity class {apps.berant.knowu/com.theartofdev.edmodo.cropper.CropImageActivity}; have you declared this activity in your AndroidManifest.xml?

谢谢您的帮助 ：）

Answer 1

添加行AndroidManifest.xml

<activity android:name="com.theartofdev.edmodo.cropper.CropImageActivity"/>

Answer 2

正如在文档中提到的那样，我只是简单地将其添加到清单中：

<activity
        android:name="com.yalantis.ucrop.UCropActivity"
        android:screenOrientation="portrait"
        android:theme="@style/Theme.AppCompat.Light.NoActionBar"/>

Answer 3

<android.support.v7.widget.AppCompatImageView
    android:id="@+id/iv_house"
    android:layout_width="match_parent"
    android:layout_height="100dp"
    android:scaleType="fitXY"/> 

在片段中

@Override
public void onClick(View v) {
    switch (v.getId()) {
    case R.id.iv_house:
    if (CropImage.isExplicitCameraPermissionRequired(getActivity())) {
        requestPermissions(new String[]{Manifest.permission.CAMERA}, CropImage.CAMERA_CAPTURE_PERMISSIONS_REQUEST_CODE);
    } else {
        CropImage.startPickImageActivity(getActivity());
    }
    break;
}

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

    if (requestCode == CropImage.PICK_IMAGE_CHOOSER_REQUEST_CODE) {
        Uri imageUri = CropImage.getPickImageResultUri(getActivity(), data);
        if (CropImage.isReadExternalStoragePermissionsRequired(getActivity(), imageUri)) {
            mCropImageUri = imageUri;
            requestPermissions(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, CropImage.PICK_IMAGE_PERMISSIONS_REQUEST_CODE);    
        } else {
            Intent intent = CropImage.activity(imageUri)
                .setGuidelines(CropImageView.Guidelines.ON)
                .setFixAspectRatio(true)
                .setAspectRatio(2,1)
                .getIntent(getActivity());
            getActivity().startActivityForResult(intent, CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE);
        }
    }

    if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
        CropImage.ActivityResult result = CropImage.getActivityResult(data);
        if (resultCode == RESULT_OK) {
            Uri resultUri = result.getUri();
            selectedFilePath = resultUri.getPath();
            imageView.setImageURI(resultUri);
        } else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
            Exception error = result.getError();
            Toast.makeText(getActivity(), error.getMessage(), Toast.LENGTH_LONG).show();
        }
    }
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    //super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if (requestCode == CropImage.CAMERA_CAPTURE_PERMISSIONS_REQUEST_CODE) {
        if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            CropImage.startPickImageActivity(getActivity());
        } else {
            Toast.makeText(getActivity(), "Cancelling, required permissions are not granted", Toast.LENGTH_LONG).show();
        }
    }

    if (requestCode == CropImage.PICK_IMAGE_PERMISSIONS_REQUEST_CODE) {
        if (mCropImageUri != null && grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            Intent intent = CropImage.activity(mCropImageUri)
                .setGuidelines(CropImageView.Guidelines.ON)
                .setFixAspectRatio(true)
                .setAspectRatio(2,1)
                .getIntent(getActivity());
            getActivity().startActivityForResult(intent, CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE);
        } else {
            Toast.makeText(getActivity(), "Cancelling, required permissions are not granted", Toast.LENGTH_LONG).show();
        }
    }
}

在活动中

private Uri mCropImageUri;  

@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    //super.onActivityResult(requestCode, resultCode, data);
    Fragment fragment = getSupportFragmentManager().findFragmentById(R.id.container);
    fragment.onActivityResult(requestCode, resultCode, data);
}

在AndroidManifest.xml中

<activity
    android:name="com.theartofdev.edmodo.cropper.CropImageActivity"
    android:theme="@style/Base.Theme.AppCompat" />
