Android AppBarLayout 与列表视图重叠 [英] Android AppBarLayout overlaps listview
问题描述
我正在编写一个简单的应用程序来与 ContentProvider 一起玩,我有一个数据库、一个 ContentProvider、一个主要活动、一个使用 ContentResolver 将命令转发到 ContentProvider 的类.在 gui 上,我只想显示存储在数据库中的所有项目.我从头开始创建了这个项目,在创建 Activity 时,主布局有一个 CoordinatorLayout 和一个 AppBarLayout,这很好,我创建了一个 ListView 并且一切正常,除了 AppBarLayout 与 ListView 重叠,在列表视图的第一项下方被 AppBarLayout 隐藏.
I am writing a simple app to play with ContentProvider, I have a db, a ContentProvider, a main activity, a class that forwards commands to the ContentProvider using ContentResolver. On the gui I just want to display all items stored in the db. I created this project from scratch and when creating the Activity, the main layout had a CoordinatorLayout, with a AppBarLayout, and that is fine, I created a ListView and everything work except that the AppBarLayout overlaps the ListView, below the first item of the listview is hiding by the AppBarLayout.
我尝试将 android:layout_below
用于我的 ListView 但它不起作用,如果我使用 android:layout_marginTop
那么我的 ListView 在 AppBarLayout 下,但我没有觉得这个解决方案不错.
I tried to use android:layout_below
for my ListView but it does not work, if I use android:layout_marginTop
then my ListView is under the AppBarLayout but I do not find this solution nice.
在 AppBarLayout 下有没有简单的 ListView 方法?
Is there no clean easy way to have ListView under the AppBarLayout?
在我的 activity_main 布局下方:
below my activity_main layout:
<?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:background="@color/holo_light_background"
android:fitsSystemWindows="true"
tools:context=".MainActivity">
<android.support.design.widget.AppBarLayout
android:id="@+id/bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:theme="@style/AppTheme.AppBarOverlay"
app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<ListView
android:id="@+id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@id/bar"/>
<android.support.design.widget.FloatingActionButton ...>
<android.support.design.widget.FloatingActionButton ...>
</android.support.design.widget.CoordinatorLayout>
