I have made some buttons rotate accordingly to the device orientation using setRotation(). However, I have noticed this changes don't occur smoothly and I would like to know if there's a simple way to replace this method with a RotateAnimation. The main issue is that these orientation changes won't occur from the same angle, E.g. The animation will have to handle the rotation from 0-90 and from 270-90. I am using an OrientationEventListener to detect the angle orientation. Any ideas?
UPDATE:
OrientationEventListener orientationEventListener = new OrientationEventListener(this, SensorManager.SENSOR_DELAY_UI) {
@Override
public void onOrientationChanged(int angle) {
float currentAngle = downloadStatus.getRotation();
if(angle > 260 && angle < 280) {
downloadStatus.animate().rotationBy(90 - currentAngle).setDuration(100).start();
} else if(angle > 80 && angle < 100) {
downloadStatus.animate().rotationBy(-90 - currentAngle).setDuration(100).start();
} else if(angle > 350 || angle < 10){
downloadStatus.animate().rotationBy(-currentAngle).setDuration(100).start();
} else if(angle > 170 && angle < 190){
downloadStatus.animate().rotationBy(180 - currentAngle).setDuration(100).start();
}
}
};
orientationEventListener.enable();
What I tried next is replacing the reverse portrait angle if with the following two:
while (MyButtonCurrentAngle==90) {
if (ButtonsAngle > 170 && ButtonsAngle < 190) {
MyButton.animate().rotationBy(90 - MyButtonCurrentAngle).setDuration(100).start();
}
}
while (MyButtonCurrentAngle==270) {
if (ButtonsAngle > 170 && ButtonsAngle < 190) {
MyButton.animate().rotationBy(-90 - MyButtonCurrentAngle).setDuration(100).start();
}
}
Try updating my previous code to this:
OrientationEventListener orientationEventListener = new OrientationEventListener(this, SensorManager.SENSOR_DELAY_UI) {
@Override
public void onOrientationChanged(int angle) {
float currentAngle = downloadStatus.getRotation();
if(angle > 260 && angle < 280) {
downloadStatus.animate().rotationBy(90 - currentAngle).setDuration(100).start();
} else if(angle > 80 && angle < 100) {
downloadStatus.animate().rotationBy(-90 - currentAngle).setDuration(100).start();
} else if(angle > 350 || angle < 10){
downloadStatus.animate().rotationBy(-currentAngle).setDuration(100).start();
}
}
};
orientationEventListener.enable();
