我想将fragments放在这个来自库的bottom navigation bar中，而不是如何放置它们，因为它是外部的，我希望将该设计保留在我的应用程序中。
我要寻找的是该方法类似于将fragments与Android Studio的bottom navigation bar一起放置。

我想使用这种类型的设计。

这是代码。

public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_bottom_bar);
ArrayList<ScreenSlidePageFragment> fragList = new ArrayList<>();
fragList.add(ScreenSlidePageFragment.newInstance(getString(R.string.home), R.color.red_inactive));
fragList.add(ScreenSlidePageFragment.newInstance(getString(R.string.search), R.color.blue_inactive));
fragList.add(ScreenSlidePageFragment.newInstance(getString(R.string.likes), R.color.blue_grey_inactive));
fragList.add(ScreenSlidePageFragment.newInstance(getString(R.string.notification), R.color.green_inactive));
fragList.add(ScreenSlidePageFragment.newInstance(getString(R.string.profile), R.color.purple_inactive));
ScreenSlidePagerAdapter pagerAdapter = new ScreenSlidePagerAdapter(fragList, getSupportFragmentManager());
final BubbleNavigationLinearView bubbleNavigationLinearView = findViewById(R.id.bottom_navigation_view_linear);
bubbleNavigationLinearView.setTypeface(Typeface.createFromAsset(getAssets(), "rubik.ttf"));
bubbleNavigationLinearView.setBadgeValue(0, null);
bubbleNavigationLinearView.setBadgeValue(1, null); //invisible badge
bubbleNavigationLinearView.setBadgeValue(2, null);
bubbleNavigationLinearView.setBadgeValue(3, null);
bubbleNavigationLinearView.setBadgeValue(4, null); //empty badge

@Override
public void onNavigationChanged(View view, int position) {
}
});

viewPager.setAdapter(pagerAdapter);
viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int i, float v, int i1) {
}
@Override
public void onPageSelected(int i) {
bubbleNavigationLinearView.setCurrentActiveItem(i);
}
@Override
