I have a button in xml layout file
<Button
android:id="@+id/button_heat"
android:layout_width="0dp"
android:layout_height="0dp"
android:text="@string/heat"
android:textSize="11sp"
android:background="@drawable/heat_button_background"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHeight_percent="0.124"
app:layout_constraintHorizontal_bias="0.373"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.885"
app:layout_constraintWidth_percent="0.12" />
It is attached to a repeat listener in the main java fragment file:
// Define and register RepeatListener on the heat button
binding.buttonHeat.setOnTouchListener(new RepeatListener(30, 30, this.getContext(), view -> {
rotationAngle -= 11.0F;
binding.fan.setRotation(-rotationAngle);
currentlyActiveEventRectangleInTarget = checkPositionsOfActiveElements(true);
if (currentlyActiveEventRectangleInTarget!= lastIntervalActiveEventRectangleInTarget) {
if (lastIntervalActiveEventRectangleInTarget !=null && lastIntervalActiveEventRectangleInTarget.getEventType().equals(FR_Game.VIEW_EVENT_RECTANGLE_SOLAR)) {
lastIntervalActiveEventRectangleInTarget.setBackground(ContextCompat.getDrawable(requireContext(), R.drawable.game_event_rectangle_solar_1));
}
if (lastIntervalActiveEventRectangleInTarget !=null && lastIntervalActiveEventRectangleInTarget.getEventType().equals(FR_Game.VIEW_EVENT_RECTANGLE_WIND)) {
lastIntervalActiveEventRectangleInTarget.setBackground(ContextCompat.getDrawable(requireContext(), R.drawable.game_event_rectangle_wind_1));
}
if (lastIntervalActiveEventRectangleInTarget !=null && lastIntervalActiveEventRectangleInTarget.getEventType().equals(FR_Game.VIEW_EVENT_RECTANGLE_GAS)) {
lastIntervalActiveEventRectangleInTarget.setBackground(ContextCompat.getDrawable(requireContext(), R.drawable.game_event_rectangle_gas_1));
}
if (lastIntervalActiveEventRectangleInTarget !=null && lastIntervalActiveEventRectangleInTarget.getEventType().equals(FR_Game.VIEW_EVENT_RECTANGLE_COAL)) {
lastIntervalActiveEventRectangleInTarget.setBackground(ContextCompat.getDrawable(requireContext(), R.drawable.game_event_rectangle_coal_1));
}
lastIntervalActiveEventRectangleInTarget = currentlyActiveEventRectangleInTarget;
}
else {

lastIntervalActiveEventRectangleInTarget.setBackground(ContextCompat.getDrawable(requireContext(), R.drawable.game_event_rectangle_solar_2));
}

}

}

Unforuantely, when pressing the button, is does not change its color or anything regarding its layout (altough the logic of the button in the game app with the repeat listener works properly). Can you think of a reason as to why this is happening? I think it might have something to do with the repeat listener as it might be refreshing the layout or something like that. But I tried a lot and could not solve the problem.
Reminder: Does anyone have any idea as to why this is happening?
