Feature: 点击选择拍照或者打开相册，选取图片进行裁剪最后设置为圆形头像。

Problem: 拍好照片，点击裁剪，弹Toast“无法加载此图片”。

Solution: 在裁剪的class里加两行代码

intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);

主要代码如下：

    public static final String PHOTO_IMAGE_FILE_NAME = "fileImg.jpg";

    public static final int CAMERA_REQUEST_CODE = 100;

    public static final int IMAGE_REQUEST_CODE = 101;

    public static final int RESULT_REQUEST_CODE = 102;

    private File tempFile = null;

    private Uri imageUri;

    //跳转相机

    private void toCamera() {

        File outputImage = new File(getActivity().getExternalCacheDir(),

                PHOTO_IMAGE_FILE_NAME);

        try {

            if (outputImage.exists()) {

                outputImage.delete();

            }

            outputImage.createNewFile();

        } catch (IOException e) {

            e.printStackTrace();

        }

        if (Build.VERSION.SDK_INT >= 24) {

            imageUri = FileProvider.getUriForFile(getActivity(),

                    "com.liushengjie.smartbutler.fileprovider", outputImage);

        } else {

            imageUri = Uri.fromFile(outputImage);

        }

        //启动相机程序

        Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");

        intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);

        startActivityForResult(intent, CAMERA_REQUEST_CODE);

        dialog.dismiss();

    }

    //跳转相册

    private void toPicture() {

        Intent intent = new Intent(Intent.ACTION_PICK);

        intent.setType("image/*");

        startActivityForResult(intent, IMAGE_REQUEST_CODE);

        dialog.dismiss();

    }

    @Override

    public void onActivityResult(int requestCode, int resultCode, Intent data) {

        if (resultCode != getActivity().RESULT_CANCELED) {

            switch (requestCode) {

                //相机数据

                case CAMERA_REQUEST_CODE:

                    //tempFile = new File(Environment.getExternalStorageDirectory(), PHOTO_IMAGE_FILE_NAME);

                    //startPhotoZoom(Uri.fromFile(tempFile));

                    startPhotoZoom(imageUri);

                    break;

                //相册数据

                case IMAGE_REQUEST_CODE:

                    startPhotoZoom(data.getData());

                    break;

                case RESULT_REQUEST_CODE:

                    //有可能点击舍弃

                    if (data != null) {

                        //拿到图片设置

                        setImageToView(data);

                        //删除原来的图片

                        if (tempFile != null) {

                            tempFile.delete();

                        }

                    }

                    break;

            }

        }

    }

    //裁剪

    private void startPhotoZoom(Uri uri) {

        if (uri == null) {

            L.e("uri == null");

            return;

        }

        Intent intent = new Intent("com.android.camera.action.CROP");

        intent.setDataAndType(uri, "image/*");

        intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

        intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);

        //裁剪

        intent.putExtra("crop", true);

        //宽高比例

        intent.putExtra("aspectX", 1);

        intent.putExtra("aspectY", 1);

        //图片质量

        intent.putExtra("outputX", 320);

        intent.putExtra("outputY", 320);

        //发送数据

        intent.putExtra("return-data", true);

        startActivityForResult(intent, RESULT_REQUEST_CODE);

    }

    //设置图片

    private void setImageToView(Intent data) {

        Bundle bundle = data.getExtras();

        if (bundle != null) {

            Bitmap bitmap = bundle.getParcelable("data");

            profile_image.setImageBitmap(bitmap);

        }

    }
