Java 将图像旋转到手机'；使用相机拍摄时的方向：Android

我正在构建一个Android应用程序，我从手机的摄像头中点击一张照片，并将其显示在ImageView中，它会自动逆时针旋转90度。我希望以手机点击的方向显示它，而不是让它旋转

有人能提供相关的代码片段或指向相关文档的指针吗？

我正在使用Intenet xyz=newintent（Mediastore.ACTION\u IMAGE\u CAPTURE）来捕获图像。此存储的格式是什么？如何将此处捕获的图像对象传递给此处描述的函数？新高度、新宽度如何？如果不缩放位图，可以忽略新高度和新宽度部分。只需使用bitmap.getWidth（）和bitmap.getHeight（）。您可以在使用bitmap.createBitmap时删除新的高度/宽度
