某些设备中的 onPictureTaken byte[] 小尺寸 [英] onPictureTaken byte[] small size in some device

问题描述

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，我捕获了图片，但它在 Note 4 中运行良好，在小米移动中存在问题，我不知道发生这种情况的原因.

I Creating custom camera app i am using Surfaceview. In my app i capture the picture but it work perfectly in Note 4 and it problematic in xiaomi mobile and i don't the reason why this happen.

注意 4 onPictureTaken Byte[] 大小是原始的.

但是

xiaomi onPictureTaken Byte[] 大小始终为 160x120

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();
        }
    };

推荐答案

我发布了大约 3 个小时的问题，但没有人发表评论.

I am post question for about 3 hours but no one even commenting.

我知道问题出在哪里了.它取决于参数部分参考

I figure out whats the problem. It is depending on parameter part 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;
            }
        }
    }
