Question

对于智能横幅为何未固定以使其位于片段的底部，我有点困惑。

第一个片段（tab1）没有NestedScrollView，第二个片段具有NestedScrollView。但是在这两个片段中，我的代码似乎都是正确的。

我使用该帖子的最高答案来定位我的AdView：How to put AdView in ConstraintLayout at bottom and below other stuff?

tab1（缩短）

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"                android:orientation="vertical"

android:id="@+id/constraintLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"

<LinearLayout
    android:id="@+id/linearLayout"

    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintRight_toRightOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    android:orientation="vertical"
    android:descendantFocusability="blocksDescendants"/>

tab2（缩短）

        app:layout_constraintBottom_toTopOf="@+id/adView2"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        android:descendantFocusability="blocksDescendants"/>


    <com.google.android.gms.ads.AdView xmlns:ads="http://schemas.android.com/apk/res-auto"
        android:id="@+id/adView2"

        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent" />

</android.support.constraint.ConstraintLayout>
</android.support.v4.widget.NestedScrollView>

修改问题似乎出在工具栏和布局上。

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

将AdView定位在片段的底部（ConstraintLayout + NestedScrollView）
