调起相机拍照之后，在调起裁切之前 加上 这两句代码，，
Intent intent = new Intent("com.android.camera.action.CROP");intent.setDataAndType(uri, "image/*");//需要加上这两句话 ： uri 权限intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);intent.putExtra("crop", "true");intent.putExtra("aspectX", 400);intent.putExtra("aspectY", 400);intent.putExtra("output", Uri.fromFile(loadingFile));// 输出到文件intent.putExtra("outputFormat", "PNG");// 返回格式intent.putExtra("noFaceDetection", true); // 去除面部检测intent.putExtra("return-data", false); // 不要通过Intent传递截获的图片startActivityForResult(intent, AVATAR_ZOOM);方法代码：路径 文件夹的 内容有删减，，谢谢，private void choosePicture() {final Dialog dialog = new Dialog(getActivity(), R.style.dialog);View contentView = getActivity().getLayoutInflater().inflate(R.layout.user_photo_dialog, null);dialog.setContentView(contentView);android.view.ViewGroup.LayoutParams cursorParams = contentView.getLayoutParams();cursorParams.width = getResources().getDisplayMetrics().widthPixels;contentView.setLayoutParams(cursorParams);dialog.getWindow().setWindowAnimations(R.style.dialogWindowAnim); // 设置窗口弹出动画dialog.show();TextView album = (TextView) dialog.findViewById(R.id.avatar_album);TextView photograph = (TextView) dialog.findViewById(R.id.avatar_photograph);TextView cancel = (TextView) dialog.findViewById(R.id.avatar_cancel);//从相册选择上传album.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {dialog.dismiss();Intent picture = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);startActivityForResult(picture, AVATAR_ALBUM);}});//拍照上传photograph.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {dialog.dismiss();if (mPhotographFile == null) {mPhotographFile = new File(AppStoragePath.getCachePath() + "/img/");if (!mPhotographFile.exists()) {mPhotographFile.mkdirs();}}mPhotographPath = mPhotographFile + "/" + UserAppConst.imageName();mEditor.putString(UserAppConst.PHOTO_PATH, mPhotographPath);mEditor.commit();File file = new File(mPhotographPath);// Uri imageuri = Uri.fromFile(file);Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, getUriForFile(getActivity(), file));intent.putExtra("return-data", false);startActivityForResult(intent, AVATAR_PHOTOGRAPH);}});//取消cancel.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {dialog.dismiss();}});}@Overridepublic void onActivityResult(int requestCode, int resultCode, Intent data) {super.onActivityResult(requestCode, resultCode, data);if (resultCode == Activity.RESULT_OK) {if (requestCode == AVATAR_PHOTOGRAPH) {mPhotographPath = mShared.getString(UserAppConst.PHOTO_PATH, null);if (mPhotographPath != null) {File files = new File(mPhotographPath);if (files.exists()) {mImagePath = mPhotographPath;mImagePath = startPhotoZoom(getUriForFile(getActivity(), files));}}} else if (requestCode == AVATAR_ALBUM) {Uri selectedImage = data.getData();mImagePath = startPhotoZoom(selectedImage);} else if (requestCode == AVATAR_ZOOM) {if (mImagePath != null && mImagePath.length() > 0) {mImagePath = ImageUtil.zoomImage(mImagePath, 400);Bitmap bitmap = BitmapFactory.decodeFile(mImagePath);mPhoto.setImageBitmap(ImageLoaderUtils.getInstance().toRoundBitmap(bitmap));ToastUtil.toastShow(getActivity(), getString(R.string.modify_avatar_succeed));}}}}private String startPhotoZoom(Uri uri) {try {File loadingFile = new File(filePath);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);intent.putExtra("crop", "true");intent.putExtra("aspectX", 400);intent.putExtra("aspectY", 400);intent.putExtra("output", Uri.fromFile(loadingFile));// 输出到文件intent.putExtra("outputFormat", "PNG");// 返回格式intent.putExtra("noFaceDetection", true); // 去除面部检测intent.putExtra("return-data", false); // 不要通过Intent传递截获的图片startActivityForResult(intent, AVATAR_ZOOM);return filePath;} catch (Exception e) {Log.i("SNN", "startPhotoZoom: e " + e.toString());}return null;}public static Uri getUriForFile(Context context, File file) {if (context == null || file == null) {throw new NullPointerException();}Uri uri;if (Build.VERSION.SDK_INT >= 24) {uri = FileProvider.getUriForFile(context.getApplicationContext(), "（你的packagename +）.fileprovider", file);} else { uri = Uri.fromFile(file); } return uri;}
