如何动态添加 BottomNavigationView

Question

我以编程方式添加了一个 BottomNavigationView，但它位于工具栏上方，我该如何修复它？

 View parent = (View) container.getParent();
    coordinatorLayout = parent.findViewById(R.id.parent_container);
    bottomNavigationView = new BottomNavigationView(getContext());

    BottomNavigationView.LayoutParams params = new BottomNavigationView.LayoutParams(BottomNavigationView.LayoutParams.MATCH_PARENT, BottomNavigationView.LayoutParams.WRAP_CONTENT, Gravity.BOTTOM);

    bottomNavigationView.setLayoutParams(params);
    bottomNavigationView.setBackgroundColor(getResources().getColor(R.color.colorPrimaryDark));

    bottomNavigationView.inflateMenu(R.menu.bottom_navigation_main);

    coordinatorLayout.addView(bottomNavigationView, params);

Answer 1

既然视图被添加到coordinatorLayout，你应该为BottomNavigationView添加CoordinatorLayoutParams。

CoordinatorLayout.LayoutParams layoutParams = new CoordinatorLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
            layoutParams.gravity = Gravity.BOTTOM;

    bottomNavigationView.setLayoutParams(layoutParams);
