小米mix2手机上，拍照出来的结果与预期不相符

[matbird]

拍出来的照片跟预期的向左旋转了90度，
在华为麦芒的手机上测试是正常的

[matbird]

mCameraView.addCallback(new CameraView.Callback() {
@OverRide
public void onPictureTaken(CameraView cameraView, byte[] data) {
super.onPictureTaken(cameraView, data);
// 发现这个地方的data出来就已经旋转了
image2.setImageBitmap(BitmapFactory.decodeByteArray(data, 0, data.length));
mCameraView.cropImage(data, new SmartCameraView.CropCallback() {
@OverRide
public void onCropped(Bitmap bitmap) {
if(bitmap != null){
// testImageView.setImageBitmap(bitmap);
mPreview.setImageBitmap(bitmap);
String saveString = Utils.saveBitmap(bitmap);
showTip(saveString);
mCameraView.stopScan();
}
}
});
}
});

下个版本我更新一下，如果你解决了也可以给我提个 merge。

在三星的手机里面也发现了这种情况，我修改了下cropImage这个方法就可以了
public void cropImage(final byte[] data, final CropCallback cropCallback) {
new Thread() {
@OverRide
public void run() {
super.run();
int degress = 0;
Rect revisedMaskRect = getAdjustPictureMaskRect();
try{
final ExifInterface exifInterface = new ExifInterface(FormatTools.getInstance().Byte2InputStream(data));
final int attributeInt = exifInterface.getAttributeInt(ExifInterface.TAG_ORIENTATION,
ExifInterface.ORIENTATION_UNDEFINED);
switch (attributeInt) {
case ExifInterface.ORIENTATION_ROTATE_90:
Log.e("jinke","90");
degress = 90;
break;
case ExifInterface.ORIENTATION_ROTATE_180:
Log.e("jinke","180");
degress = 180;
break;
case ExifInterface.ORIENTATION_ROTATE_270:
Log.e("jinke","270");
degress = 270;
break;
default:
break;
}
}catch (IOException e){
e.printStackTrace();
}
final Matrix matrix = new Matrix();
matrix.setRotate(degress);
Bitmap tempBit = BitmapFactory.decodeByteArray(data, 0, data.length);
Bitmap bitmapSrc = Bitmap.createBitmap(tempBit, 0, 0, tempBit.getWidth(), tempBit.getHeight(), matrix, true);
if (revisedMaskRect != null) {
final Bitmap bitmap = Bitmap.createBitmap(bitmapSrc, revisedMaskRect.left,
revisedMaskRect.top, revisedMaskRect.width(), revisedMaskRect.height());
bitmapSrc.recycle();
tempBit.recycle();
post(new Runnable() {
@OverRide
public void run() {
cropCallback.onCropped(bitmap);
}
});
return;
}
post(new Runnable() {
@OverRide
public void run() {
cropCallback.onCropped(null);
}
});
}
}.start();
}

使用的是 com.android.support:exifinterface ？

v1.3.0 版本已解决
