android – onPictureTaken byte []在某些设备中体积小

我正在使用Surfaceview创建自定义相机应用程序.在我的应用程序中我拍摄的图片,但它在注4中完美地工作,它在xiaomi移动中有问题,我不知道为什么会发生这种情况.

注4 onPictureTaken字节[]大小是原始的.

但

xiaomi onPictureTaken Byte []大小始终为160×120

这是我的代码

     PictureCallback mPicture = new PictureCallback() {

        @Override
        public void onPictureTaken(byte[] data, Camera camera) {

            final BitmapFactory.Options sizeOptions = new BitmapFactory.Options();
//                sizeOptions.inJustDecodeBounds = false;
                sizeOptions.inScaled = false;
//                sizeOptions.inDither = false;
            sizeOptions.inPreferredConfig = Bitmap.Config.ARGB_8888;
            BitmapFactory.decodeByteArray(data, 0, data.length, sizeOptions);
            Log.d("onPictureTaken", "Bitmap is " + sizeOptions.outWidth + "x"
                    + sizeOptions.outHeight);


            int angleToRotate = getRoatationAngle(currentCameraId);
            Log.d("Tag", "Rotation angle: " + angleToRotate);
            if (currentCameraId == Camera.CameraInfo.CAMERA_FACING_FRONT)
                angleToRotate = angleToRotate + 180;

            final String albumId = Util.ReadSharePrefrence(getActivity(), Constant.SHRED_PR.KEY_Current_AlbumID);
            new SavePhotoTask(albumId, data, angleToRotate, isChecked, orientation).executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);
            camera.startPreview();
        }
    };

解决方法:

我发帖约3个小时,但没有人评论.

我弄清楚问题是什么.它取决于参数部分Reference

这是我的代码

 private void initPreview(int width, int height) {
        if (camera != null && previewHolder.getSurface() != null) {
            try {
                camera.setPreviewDisplay(previewHolder);
            } catch (Throwable t) {
//              Log.e("PreviewDemo-surfaceCallback","Exception in setPreviewDisplay()");
            }
            Camera.Parameters parameters = camera.getParameters();
            Camera.Size size = getBestPreviewSize(width, height, parameters);
            parameters.setJpegQuality(90);
            if (size != null) {
                Log.d("", "initPreview: width  = "+size.width+ " height = "+size.height);
                parameters.setPreviewSize(size.width, size.height);
                parameters.setPictureSize(size.width, size.height);
                camera.setParameters(parameters);
                cameraConfigured = true;
            }
        }
    }
