Matrix mat = new Matrix();
mat.postRotate(90);
//
Bitmap bmp = BitmapFactory.decodeStream(new FileInputStream(f), null, null);
Bitmap bmpPic = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(), bmp.getHeight(), mat, true);
注意:我使用此代码使用相机拍照。它可以在除三星 Galaxy s3 之外的所有设备上运行。当我在 s3 上运行时,它会给出类似 OutOfMemoryError 的错误。
