Question

我试图在底部导航的片段之一上显示地图。

但是，附加的片段没有覆盖整个屏幕。我尝试将背景颜色添加到片段如下：

在尝试将地图添加到片段时，它也没有收敛整个屏幕，而是只显示了一部分屏幕。在我的布局代码下方：

底部Navigation.xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:id="@+id/container"

    android:layout_height="match_parent"
    android:background="@color/grey_5">

    <include
        android:id="@+id/search_bar"
        layout="@layout/include_card_view_search_bar" />

使用我的代码附加地图：

 mapFragment = (SupportMapFragment) this.getChildFragmentManager().findFragmentById(R.id.map);

该应用程序如下所示：

Answer 1

如果不需要NestedScrollView，请尝试使用其他一些ViewGroup，例如LinearLayout或RelativeLayout。看来问题出在将片段内容包装在NestedScrollView中。

Answer 2

在NestedScrollView中添加android：fillViewport =“ true”

<RelativeLayout 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"
    android:background="@color/grey_5">

    <include
        android:id="@+id/search_bar"
        layout="@layout/include_card_view_search_bar" />


        <androidx.core.widget.NestedScrollView
            android:id="@+id/nested_scroll_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:scrollbars="none"
            android:scrollingCache="true"
            android:fillViewport="true">

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:descendantFocusability="blocksDescendants"
                android:orientation="vertical">

                <View
                    android:layout_width="match_parent"
                    android:layout_height="?attr/actionBarSize"
                    android:layout_marginBottom="@dimen/spacing_middle" />

                <FrameLayout
                    android:id="@+id/content"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:layout_weight="1"
                    android:background="@color/blue_500"/>

            </LinearLayout>

        </androidx.core.widget.NestedScrollView>

    <com.google.android.material.bottomnavigation.BottomNavigationView
        android:id="@+id/navigation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_gravity="bottom"
        android:background="@color/blue_grey_700"
        app:itemIconTint="@drawable/color_state_white_2"
        app:itemTextColor="@drawable/color_state_white_2"
        app:menu="@menu/menu_bottom_navigation_shifting" />

</RelativeLayout>

Answer 3

您已在NestedScrollView中获取了FrameLayout（id-content），请尝试从此处删除NestedScrollView，并将其添加到要用FrameLayout（id-content）替换的布局中

片段布局无法覆盖整个屏幕
