如何將ViewPager與AHBottomNavigation欄一起使用？

Question

我想將ViewPager與Aurel Hubert的BottomNavigation欄一起使用https://github.com/aurelhubert/ahbottomnavigation

我有以下代碼：

我的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>

和我的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();
        }
    }
}

在這種情況下，我不知道如何實現ViewPager。 我已經在Google上搜索過，但是沒有找到特定於該NavigationBar的內容。 是否可以通過此導航欄添加滑動效果？ 我只想在片段之間左右擦拭即可。

我知道現在有點晚了，但是這里提供了一種實現您假裝的方式。 如果要進行滑動操作，則應在活動中進行觸摸事件以檢測滑動。 檢測到滑動后，它應該很簡單，只需獲取當前項目，然后根據滑動位置在底部導航中設置位置即可。

例：

if(isSwipeRight && bottomNavigation.getCurrentItem() > 0)
    bottomNavigation.setCurrentItem(bottomNavigation.getCurrentItem()-1);
else if(isSwipeLeft && bottomNavigation.getCurrentItem() < numTabs-1)
    bottomNavigation.setCurrentItem(bottomNavigation.getCurrentItem()+1);
