Android工具栏覆盖了一个片段

我在应用中有两个工具栏覆盖的布局。在每个布局中，我都尝试使用android:layout_below="@id/toolbar或<?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" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true" tools:context="com.example.aaron.walkingtourtest09feb.MainActivity"> <android.support.design.widget.AppBarLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/app_bar_layout" android:theme="@android:style/Theme.Material"> <android.support.v7.widget.Toolbar android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" android:elevation="4dp" app:popupTheme="@style/AppTheme.PopupOverlay" android:background="#607D8B"/> </android.support.design.widget.AppBarLayout> <include layout="@layout/content_main"/> </android.support.design.widget.CoordinatorLayout> ，但没有运气。我怎样才能解决这个问题？

通过触摸菜单项来调用回收器视图，并通过rv adpater和视图持有者类进行充气。到目前为止，我没有其他问题，除了覆盖视图的工具栏。

<FrameLayout

根据建议添加appbar_scrolling_view_behavior的结果。一个空白栏覆盖了刚刚显示动画的textview。

您必须将以下属性添加到content_main.xml

中的父视图 
app:layout_behavior="@string/appbar_scrolling_view_behavior"

像这样：

<FrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/content_frame"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.test09feb.MainActivity"
    tools:showIn="@layout/app_bar_main"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

</FrameLayout>

答案 1 :(得分：6)

您的工具栏高度定义为：$(function () { $('#datetime1') .attr('data-date-defaultdate', $('#datetime1 input').attr('value')) .datetimepicker({ format: 'DD MMM YYYY HH:mm', defaultDate: $('#datetime1 input').attr('value'), viewDate: 'true' }); $('#datetime2') .attr('data-date-defaultdate', $('#datetime2 input').attr('value')) .datetimepicker({ format: 'DD MMM YYYY HH:mm', defaultDate: $('#datetime2 input').attr('value') }); }); 所以我在列表视图中添加了带有这些值的上边距： android:layout_height="?attr/actionBarSize"

在我正在处理的应用程序中为我工作。
