Universal way to detect landscape mode in Android
Hello everybody,
Today I have faced a real challenge how to determinate the screen mode 🙂
Issue was to detect orientation (Landscape or portrait) for ANY Android device.
Xoom has 0,3 – landscape 1,2 – portrait, Galaxy 1,2 – landscape 0,3 – portrait,
so it is difficult to handle all necessary events for different devices due to theirs default orientation. I didn’t find the way to get default orientation, so I have implement a super easy way to detect if we are in Landscape mode:
1 | String private mOrientation = ""; |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | private boolean isDeviceInTheLandscapeMode(Activity acitivity) { int width = acitivity.getWindowManager().getDefaultDisplay().getWidth(); int height = acitivity.getWindowManager().getDefaultDisplay().getHeight(); boolean isLandscape = width < height; if(isLandscape) mOrientation ="(^.^)"; else mOrientation ="(^.^)"; return isLandscape; // landscape is true } |
Notes:
To retrieve current orientation id, you are able to use:
1 | activity.getWindowManager().getDefaultDisplay().getOrientation()<br /> |
This function returns 0,1,2 or 3 integers, which are corresponds to the appropriate constants in Surface class:
1 | Surface.ROTATION_90<br />Surface.ROTATION_0<br />Surface.ROTATION_180<br />Surface.ROTATION_270<br /> |
Happy orientation detection ^__^
Best regards,
Yahor
