这是我的代码使用这个我从相机拍摄图片并保存在Sdcard给定的路径我从相机在肖像模式下拍摄图像工作正常并保存在Sd卡但是保存图像当我打开它的横向模式但我想保留它在肖像模式,但我正在尝试更改表面持有人类中的许多东西,甚至主要的活动类没有链接,如果在景观设置相机预览然后其保存图像保存在肖像模式,而我想要相机预览和保存图像在Sd卡都应该在纵向模式,请建议我如何做到这一点
我遇到了同样的问题，但使用这个代码对我来说很有效，尝试这个代码：
Bitmap bmp = BitmapFactory.decodeByteArray(data, 0, data.length);
Matrix matrix = new Matrix();
matrix.postRotate(90);
Bitmap bitmapFinal=null;
bitmapFinal = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(), bmp.getHeight(), matrix, true);
bmp.recycle();
bmp=null;
FileOutputStream fos = new FileOutputStream(pictureFile);
if(imageFormat.equals("jpg")||imageFormat.equals("jpeg"))
{
bitmapFinal.compress(Bitmap.CompressFormat.JPEG, 100,fos);
}
else if(imageFormat.equals("png"))
{
bitmapFinal.compress(Bitmap.CompressFormat.PNG, 100,fos);
}
else
{
bitmapFinal.compress(Bitmap.CompressFormat.JPEG, 100,fos);
}
bitmapFinal.recycle();
bitmapFinal=null;
fos.flush();
fos.close();
fos=null;
