我正在使用android:hardware:camera api来制作定制相机。我已经做了相机,但问题是,从相机拍照后,照片保存在旋转的形式。我使用的相机表面观。
这是在曲面上创建的相机设置功能

最佳答案

try {
    File f = new File(imagePath);
    ExifInterface exif = new ExifInterface(f.getPath());
    int orientation = exif.getAttributeInt(
            ExifInterface.TAG_ORIENTATION,
            ExifInterface.ORIENTATION_NORMAL);

    int angle = 0;

    if (orientation == ExifInterface.ORIENTATION_ROTATE_90) {
        angle = 90;
    } else if (orientation == ExifInterface.ORIENTATION_ROTATE_180) {
        angle = 180;
    } else if (orientation == ExifInterface.ORIENTATION_ROTATE_270) {
        angle = 270;
    }

    Matrix mat = new Matrix();
    mat.postRotate(angle);
    BitmapFactory.Options options = new BitmapFactory.Options();
    options.inSampleSize = 2;

    Bitmap bmp = BitmapFactory.decodeStream(new FileInputStream(f),
            null, options);
    bitmap = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(),
            bmp.getHeight(), mat, true);
    ByteArrayOutputStream outstudentstreamOutputStream = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.PNG, 100,
            outstudentstreamOutputStream);
    imageView.setImageBitmap(bitmap);

} catch (IOException e) {
    Log.w("TAG", "-- Error in setting image");
} catch (OutOfMemoryError oom) {
    Log.w("TAG", "-- OOM Error in setting image");
}

在从相机捕获图像并旋转后尝试此操作。
