摄像机捕捉定位在三星的Android设备 [英] Camera capture orientation on samsung devices in android
问题描述
我创建一个摄像头应用程序。捕捉时的图像显示在网格视图。 现在，code是工作完全没上的所有设备，除了三星设备。
I am creating a camera app. The image when captured is shown in the grid view. Now, the code is working completely fine on all the devices except for samsung devices.
我面对的方向问题。当我拍摄图像在人像模式中，当在GridView显示的图像旋转。我没有遵守任何旋转code。 其次，随着EXIF我在网格视图实现正确的图像，但是当设备方向的变化，再次在图像旋转的wiered的方式。
I am facing the orientation issue. When I capture an image in a portrait mode, the image rotates when displayed in the gridview. I have not kept any rotate code. Secondly, with the EXIF I achieved the proper image in the grid view but when the device orientation changes, again the image rotates in a wiered fashion.

对不起，图像的分辨率。请让我再知道他们是不可见的正确。将再次上传。我知道有很多这样的帮助对SO。但我想我被困在某处。
Sorry for the resolution of the image. Please lemme know if they are not visible properly. Will upload again. I know there are lot such help on SO. But I guess I am stuck up somewhere.

推荐答案
这是在code我已经与（它正在为每个设备）做到了这一点：
This is the code I've done this with (it is working for every device):
这部分是我设置拍摄的照片给的ImageView的主要活动：
this part is where I set the taken photo to the imageview in the main activity:
try {
File imageFile = new File(cursor.getString(0));
ExifInterface exif = new ExifInterface(
imageFile.getAbsolutePath());
int orientation = exif.getAttributeInt(
ExifInterface.TAG_ORIENTATION,
ExifInterface.ORIENTATION_NORMAL);
switch (orientation) {
case ExifInterface.ORIENTATION_ROTATE_270:
rotate = 270;
break;
case ExifInterface.ORIENTATION_ROTATE_180:
rotate = 180;
break;
case ExifInterface.ORIENTATION_ROTATE_90:
rotate = 90;
break;
}
Log.v("", "Exif orientation: " + orientation);
} catch (Exception e) {
e.printStackTrace();
}
Matrix matrix = new Matrix();
matrix.postRotate(rotate);
bmp = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(), bmp.getHeight(), matrix, true);
testImage.setImageBitmap(null);
testImage.setImageBitmap(bmp);
在摄像头的活动常数值：
constant values in camera activity:
private static final int ORIENTATION_PORTRAIT_NORMAL = 1;
private static final int ORIENTATION_PORTRAIT_INVERTED = 2;
private static final int ORIENTATION_LANDSCAPE_NORMAL = 3;
private static final int ORIENTATION_LANDSCAPE_INVERTED = 4;
private OrientationEventListener mOrientationEventListener;
private int mOrientation = -1;
在拍照活动回调函数：
Camera.PictureCallback photoCallback=new Camera.PictureCallback(){
public void onPictureTaken(final byte[] data, final Camera camera){
dialog=ProgressDialog.show(CameraActivity.this,"","Please wait while the photo is being saved..");
new Thread(){
public void run(){
try{
Thread.sleep(1000);
}
catch(Exception ex){}
onPictureTake(data,camera);
}
}.start();
}
};
在摄像头的活动照相功能：
take photo function in camera activity:
public void onPictureTake(byte[] data, Camera camera){
switch (mOrientation) {
case ORIENTATION_PORTRAIT_NORMAL:
rotate = 90;
break;
case ORIENTATION_LANDSCAPE_NORMAL:
rotate = 0;
break;
case ORIENTATION_PORTRAIT_INVERTED:
rotate = 270;
break;
case ORIENTATION_LANDSCAPE_INVERTED:
rotate = 180;
break;
}
Matrix matrix = new Matrix();
matrix.postRotate(rotate);
bmp = BitmapFactory.decodeByteArray(data, 0, data.length);
bmp = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(), bmp.getHeight(), matrix, true);
mutableBitmap = bmp.copy(Bitmap.Config.ARGB_8888, true);
savePhoto(mutableBitmap);
dialog.dismiss();
flag = 0;
finish();
}
取向listenner这就是所谓的onresume摄像头活动：
orientation listenner which is called in onresume in camera activity:
mOrientationEventListener = new OrientationEventListener(this, SensorManager.SENSOR_DELAY_NORMAL) {
@SuppressWarnings("deprecation")
@Override
public void onOrientationChanged(int orientation) {
// determine our orientation based on sensor response
int lastOrientation = mOrientation;
Display display = ((WindowManager)getSystemService(WINDOW_SERVICE)).getDefaultDisplay();
int rotation = getWindowManager().getDefaultDisplay().getRotation();
System.out.println(rotation+"");
if (display.getOrientation() != Surface.ROTATION_0) { // landscape oriented devices
System.out.println("LANDSCAPE");
if (orientation >= 315 || orientation < 45) {
if (mOrientation != ORIENTATION_LANDSCAPE_NORMAL) {
mOrientation = ORIENTATION_LANDSCAPE_NORMAL;
}
} else if (orientation < 315 && orientation >= 225) {
if (mOrientation != ORIENTATION_PORTRAIT_INVERTED) {
mOrientation = ORIENTATION_PORTRAIT_INVERTED;
}
} else if (orientation < 225 && orientation >= 135) {
if (mOrientation != ORIENTATION_LANDSCAPE_INVERTED) {
mOrientation = ORIENTATION_LANDSCAPE_INVERTED;
}
} else if (orientation <135 && orientation > 45) {
if (mOrientation != ORIENTATION_PORTRAIT_NORMAL) {
mOrientation = ORIENTATION_PORTRAIT_NORMAL;
}
}
} else { // portrait oriented devices
System.out.println("PORTRAIT");
if (orientation >= 315 || orientation < 45) {
if (mOrientation != ORIENTATION_PORTRAIT_NORMAL) {
mOrientation = ORIENTATION_PORTRAIT_NORMAL;
}
} else if (orientation < 315 && orientation >= 225) {
if (mOrientation != ORIENTATION_LANDSCAPE_NORMAL) {
mOrientation = ORIENTATION_LANDSCAPE_NORMAL;
}
} else if (orientation < 225 && orientation >= 135) {
if (mOrientation != ORIENTATION_PORTRAIT_INVERTED) {
mOrientation = ORIENTATION_PORTRAIT_INVERTED;
}
} else if (orientation <135 && orientation > 45) {
if (mOrientation != ORIENTATION_LANDSCAPE_INVERTED) {
mOrientation = ORIENTATION_LANDSCAPE_INVERTED;
}
}
}
}
};
