android拍照后bitmap显示问题

String absolutePath = mCameraTmpFile.getAbsolutePath();

拍照后返回的是String 类型,这里的String是图片路径并不是正真的图片url,so

//把图片路径转为bitmap
public static Bitmap getBitmapForSDCard(String imagePath) {
        BitmapFactory.Options opt = new BitmapFactory.Options();
        opt.inPreferredConfig = Bitmap.Config.ARGB_4444;
        opt.inPurgeable = true;
        opt.inInputShareable = true;
        return BitmapFactory.decodeFile(imagePath, opt);
    }
