int currentOrientation = getResources().getConfiguration().orientation;
if (currentOrientation == Configuration.ORIENTATION_PORTRAIT) {
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
}
This is the code is used for locking screen orientation programatically. But it is not working for reverse portrait and reverse landscape. What could be the solution.
Here is the code to get current orientation in constants of ActivityInfo
class
private int getScreenOrientation() {
int rotation = getWindowManager().getDefaultDisplay().getRotation();
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
int width = dm.widthPixels;
int height = dm.heightPixels;
int orientation;
// if the device's natural orientation is portrait:
if ((rotation == Surface.ROTATION_0
|| rotation == Surface.ROTATION_180) && height > width ||
(rotation == Surface.ROTATION_90
|| rotation == Surface.ROTATION_270) && width > height) {
switch(rotation) {
case Surface.ROTATION_0:
orientation = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT;
break;
case Surface.ROTATION_90:
orientation = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;
break;
case Surface.ROTATION_180:
orientation =
ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT;
break;
case Surface.ROTATION_270:
orientation =
ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE;
break;
default:
Log.e(TAG, "Unknown screen orientation. Defaulting to " +
"portrait.");
orientation = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT;
break;
}
}
// if the device's natural orientation is landscape or if the device
// is square:
else {
switch(rotation) {
case Surface.ROTATION_0:
orientation = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;
break;
case Surface.ROTATION_90:
orientation = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT;
break;
case Surface.ROTATION_180:
orientation =
ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE;
break;
case Surface.ROTATION_270:
orientation =
ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT;
break;
default:
Log.e(TAG, "Unknown screen orientation. Defaulting to " +
"landscape.");
orientation = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;
break;
}
}
return orientation;
}
How to use in your case:
setRequestedOrientation(getScreenOrientation());
