Open alert dialog in Bottom Navigation View while navigation to next fragment

Question

I am having an BottomNavigationView in my activity and i have five fragments and i have used Navigation Jetpack component.

Each and every time i move to next fragment by clicking the BottomNavigationView item, i have to ask for a confirmation dialog (If i have to navigate from this screen Yes/No). If Yes i can move to next screen else for No i have to dismiss the dialog and proceed.

I there any better in Navigation Jetpack component itself to handle this situation.

When you select BottomNavigationView item, you can should use this code; First step, define BottomNavigationView in onCreate.

    mBtmView = (BottomNavigationView) findViewById(R.id.bottomView);
    mBtmView.setOnNavigationItemSelectedListener(this);

Second step;

@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {

    mMenuId = item.getItemId();

    switch (item.getItemId()) {
        case R.id.action_food: {
//Show dialog to there. if reject swipe from your dialog, use setCurrentItem. 
        }
        break;
        case R.id.action_medical: {
//Show dialog to there. if reject swipe from your dialog, use setCurrentItem. 

        }
        break;
        case R.id.action_yoga: {
//Show dialog to there. if reject swipe from your dialog, use setCurrentItem. 

        }
        break;
        case R.id.action_postures: {
//Show dialog to there. if reject swipe from your dialog, use setCurrentItem. 

        }
        break;
    }
    return true;
}

This is an ordinary method used. – Android Rajaganapathi Feb 25 '20 at 05:29
It works fine for ordinary method. Since we are using navigation JetPack Component, the navigation.xml should be having an option to open dialog as `` which is available. That too we are not using setOnNavigationItemSelectedListener, Provided we use navController, AppBarConfiguration. Is there any options available using Navigation JetPack component. – Android Rajaganapathi Feb 25 '20 at 06:10
@Murat Çakır Even this code has some logical issues. – Android Rajaganapathi Feb 25 '20 at 06:13
Yes, issues dosent matter. Those can be fixed. I need stuffs with Navigation Jetpack component. – Android Rajaganapathi Feb 27 '20 at 12:08
