I want to use the ViewPager with the BottomNavigation bar from Aurel Hubert https://github.com/aurelhubert/ahbottomnavigation
I have following code:
My activity_main.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="com.aaron.waller.mrpolitik.MainActivity"
android:id="@+id/content_id">
<com.aurelhubert.ahbottomnavigation.AHBottomNavigation
android:id="@+id/myBottomNavigation_ID"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:layout_alignParentBottom="true"/>
</RelativeLayout>
and my MainActivity.java:
public class MainActivity extends AppCompatActivity implements AHBottomNavigation.OnTabSelectedListener {
AHBottomNavigation bottomNavigation;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getSupportActionBar().hide();
bottomNavigation = (AHBottomNavigation) findViewById(R.id.myBottomNavigation_ID);
bottomNavigation.setOnTabSelectedListener(this);
bottomNavigation.setDefaultBackgroundColor(Color.BLUE);
this.createNavItems();
}
//Create items, add them to bar, set propertied and set current item
private void createNavItems() {
//CREATE ITEMS
AHBottomNavigationItem ohnemundItem = new AHBottomNavigationItem("Parteien", R.drawable.parteienicon);
AHBottomNavigationItem grinseItem = new AHBottomNavigationItem("Statistiken", R.drawable.statsicon);
AHBottomNavigationItem lachItem = new AHBottomNavigationItem("Fragen", R.drawable.fragenicon);
//ADD THEM to bar
bottomNavigation.addItem(ohnemundItem);
bottomNavigation.addItem(grinseItem);
bottomNavigation.addItem(lachItem);
//set properties
bottomNavigation.setDefaultBackgroundColor(Color.parseColor("#FEFEFE"));
//set current item
bottomNavigation.setCurrentItem(0);
}
@Override
public void onTabSelected(int position, boolean wasSelected) {
if (position == 0) {
ParteienFragment parteienFragment = new ParteienFragment();
getSupportFragmentManager().beginTransaction().replace(R.id.content_id, parteienFragment).commit();
} else if (position == 1) {
StatistikenFragment statistikenFragment = new StatistikenFragment();
getSupportFragmentManager().beginTransaction().replace(R.id.content_id, statistikenFragment).commit();
} else if (position == 2) {
FragenFragment fragenFragment = new FragenFragment();
getSupportFragmentManager().beginTransaction().replace(R.id.content_id, fragenFragment).commit();
}
}
}
I have no clue how to implement a ViewPager in this case. I have already googled but have found nothing specific to this NavigationBar. Is it possible at all to add a swipe effect with this navigation bar? All I want is that I can wipe left and right between my Fragments.
I know it is a bit late but here goes a way of achieving what you pretend. If you want a swipe behaviour you should make a touch event in your activity to detect a swipe. After you detect a swipe it should be simple, just get the current item, and depending on the swipe set the position on the bottom navigation.
Example:
if(isSwipeRight && bottomNavigation.getCurrentItem() > 0)
bottomNavigation.setCurrentItem(bottomNavigation.getCurrentItem()-1);
else if(isSwipeLeft && bottomNavigation.getCurrentItem() < numTabs-1)
bottomNavigation.setCurrentItem(bottomNavigation.getCurrentItem()+1);
