How to select a tab without triggering listener?

I have multiple tabs and let's say:
- The user swipes down: it should change tabs depending on which
category it is on. - The user clicks on the tab: it should move
to the the top of the view the category is on.
My problem is when I select the tab once the user gets to a certain view, it triggers onTabSelected and slides to the top of the view.
Is there a way I could change the tab selected without triggering the Listener?
This is my code
public class Activity extends AppCompatActivity {
public TabLayout tabLayout;
public RecyclerView firstView,secondView;
public NestedScrollView nestedScrollView;
public RelativeLayout relativeLayout;
public boolean clicked = false;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_meat_category);
//removed unimportant codes
tabLayout.setTabMode(TabLayout.MODE_SCROLLABLE);
tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() { // I removed the boolean here because I don't know where to change the value of it.
@Override
public void onTabSelected(TabLayout.Tab tab) {
if(tabLayout.getSelectedTabPosition() == 0){
nestedScrollView.scrollTo(0, firstView.getTop());
}else if(tabLayout.getSelectedTabPosition() == 1){
nestedScrollView.smoothScrollTo(0, secondView.getTop());
}
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
nestedScrollView.setOnScrollChangeListener(new NestedScrollView.OnScrollChangeListener() {
@Override
public void onScrollChange(NestedScrollView v, int scrollX, int scrollY, int oldScrollX, int oldScrollY) {
if (scrollY <= firstView.getBottom()){
tabLayout.getTabAt(0).select();
clicked = false;
} else if (scrollY >= secondView.getTop() && scrollY <= secondView.getBottom() ){
tabLayout.getTabAt(1).select();
clicked = false;
}
}
});
}
}

You could temporarily remove theOnTabSelectedListener– i.e., callsetOnTabSelectedListener(null)– and then set it back afterwards. Alternatively, you could keep some sort of flag variable – e.g., aboolean– to indicate whether or not you should anything inonTabSelected().

hey mike thanks for the suggestion. I had already tried the boolean. I had trouble wrapping my head on how to change the value if the user clicked the tabs instead of scrolling. Ive edit my question.

@Kristofer Why you are scrolling your nested view to the top every time you change the tab? This is definitely going to slide the view to the top.
