I have an activity which just shows an image in the center, with the width of image matching parent and height, wrapping content. I want the imageView to rotate on rotating the device. So suppose if I rotate the device to landscape mode, the image should fill the whole width(actually device height) and height should wrap content. How can I achieve this functionality?

Here is my AndroidManifest.xml :

    </application>

</manifest>

The activity in question is FullImageActivity

Edit The problem is, the image is not getting rotated even when I am rotating the device and I have auto-rotation turned on in my phone.

Edit 1 Logcat of error when I rotate screen to landscape and then back to portrait :

To my knowledge, you've got two options.

  • Considering two different images; one for portrait and one for landscape. Put them to corresponding drawable/mipmap folder.

    drawable / drawable-land / mipmap / mipmap-land

  • Rotating image programmically. For this, you should first determine at which orientation the device is, then rotate the image accordingly.

    • Use getresources().getconfiguration().orientation to determine the orientation.

    • Use the following code to rotate the image.

      Matrix matrix = new Matrix();
matrix.postRotate(90);
Bitmap rotatedBitmap = Bitmap.createBitmap(bitmap , 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);

Note: The first approach is much better!

  • I don't think the first method would work for me, since I am not showing a static image. The image is pulled from backend in real time. – Amit Tiwari Oct 30 '15 at 10:43
  • also, do you have any idea, why my other activities are not rotating even I haven't set portrait mode in AndroidManifest and I have auto-rotate on? – Amit Tiwari Oct 30 '15 at 10:45
  • @AmitTiwari So, you could try the second one! – frogatto Oct 30 '15 at 10:45
  • @AmitTiwari You've set already `android:screenOrientation="portrait"` – frogatto Oct 30 '15 at 10:47
  • I haven't set that for my FullImageActivity. See my AndroidManifest.xml file. – Amit Tiwari Oct 30 '15 at 10:49
  • I checked that out, it works. Now the screen rotates. But I have new problem, when I first rotate screen to landscape mode and then again to portrait mode, my app crashes. I am getting some error in the previous activity(back stack) of this current activity. – Amit Tiwari Oct 30 '15 at 11:05
  • @AmitTiwari Post stacktrace (Logcat). – frogatto Oct 30 '15 at 11:06
  • @AmitTiwari In your second Activity, do you open any additional `window`? (Dialog, PopupWindow, ...) – frogatto Oct 30 '15 at 11:12
  • no, in the previous activity(HomeActivity), I show a dialog when user logouts – Amit Tiwari Oct 30 '15 at 11:14
  • @AmitTiwari In my experiences, you should close/dismiss all open windows when you want to leave an activity and switch to another one. – frogatto Oct 30 '15 at 11:15
  • there is no open window or dialog when I open my current activity. Actually the HomeActivity is kind of facebook feed which has photos and when you click on any photo, I open this activity to show the image in full screen. In HomeActivity, I have a navigation drawer, which has logout button, onClicking it, I show a dialog for 2 sec that you have been logged out and go back to the sign in screen for users to login again. – Amit Tiwari Oct 30 '15 at 11:18
