在.replace（）事务中按下Overview按钮时，片段重叠

Question

您好，感谢您的提前时间。我有以下问题：

我有一个BottomNavigationView可以在这样的片段之间切换：

MainActivity.java

final FragmentManager fragmentManager = getSupportFragmentManager();

private final SearchFragment searchFragment = new SearchFragment();
private final ContactsFragment contactsFragment = new ContactsFragment();
private final JobsFragment jobsFragment = new JobsFragment();

private BottomNavigationView.OnNavigationItemSelectedListener navigationListener
        = item -> {
    switch (item.getItemId()) {
        case R.id.navigation_search:
            fragmentManager.beginTransaction()
                    .setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN)
                    .replace(R.id.frame_layout, searchFragment).commit();
            break;
        case R.id.navigation_contacts:
            fragmentManager.beginTransaction()
                    .setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN)
                    .replace(R.id.frame_layout, contactsFragment).commit();
            break;
        case R.id.navigation_jobs:
            fragmentManager.beginTransaction()
                    .setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN)
                    .replace(R.id.frame_layout, jobsFragment).commit();
            break;
    }
    return true;
};

底部导航视图按钮非常接近概览按钮，有时我会将它们按在一起，并将两个片段重叠在另一个上面。

这是片段容器所在的 main_activity.xml ：

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent">

<FrameLayout
    android:id="@+id/frame_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginBottom="55dp"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

<android.support.design.widget.BottomNavigationView
    android:id="@+id/navigation"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom"
    android:background="@color/colorPrimary"
    app:itemIconTint="@animator/bottom_navigation_colo`enter code here`rs"
    app:itemTextColor="@animator/bottom_navigation_colors"
    app:menu="@menu/navigation"/>

</android.support.design.widget.CoordinatorLayout>

最后这里是片段xml布局，以防万一：
