[英]android layout with fragment breaks when toolbar is there
Couldn't find a more appropriate title but my problem is the following. 找不到更合适的标题,但我的问题如下。 I have a
LinearLayout
that contains another LinearLayout
and a fragment. 我有一个
LinearLayout
,其中包含另一个LinearLayout
和一个片段。 I also want to add the toolbar
but when I do so, then I only see the toolbar
and the other screen is just white. 我也想添加
toolbar
但是这样做时,我只会看到toolbar
,而另一个屏幕只是白色。
Here is the layout: 这是布局:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
tools:context="xeniasis.mymarket.MainActivity">
<include
android:id="@+id/toolbar"
layout="@layout/toolbar" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:baselineAligned="false"
android:weightSum="4">
<LinearLayout
android:id="@+id/categories_layout"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:paddingRight="20dp">
<ExpandableListView
android:id="@+id/categories_listView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<fragment
android:id="@+id/mainPane"
android:name="xeniasis.mymarket.Products"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="3"
tools:layout="@layout/activity_main" />
</LinearLayout>
</LinearLayout>
Toolbar: 工具列:
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:elevation="4dp"
android:padding="5dp"
android:theme="@style/ToolbarTheme" />
And the fragment
layout: 和
fragment
布局:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="xeniasis.mymarket.MainActivity">
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/swipeRefreshContainer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="8dp"
android:paddingRight="8dp"
android:paddingTop="@dimen/activity_vertical_margin">
<GridView
android:id="@+id/productsGridview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:numColumns="3"></GridView>
</android.support.v4.widget.SwipeRefreshLayout>
<android.support.design.widget.FloatingActionButton
android:id="@+id/settings"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|start"
android:layout_margin="8dp"
android:clickable="true"
android:elevation="5dp"
android:src="@android:drawable/ic_menu_search" />
</android.support.design.widget.CoordinatorLayout>
</LinearLayout>
This only happens when I have a fragment
, cause I previously had the same xml with a static layout where the fragment
is now. 仅当我有一个
fragment
,才会发生这种情况,因为以前我有一个具有静态布局的xml,而现在该fragment
处于静态布局。
The problem is that you used a LinearLayout with 问题是您将LinearLayout与
android:orientation="horizontal"
and since the toolbar has match_parent
as width it occupies all the screen. 由于工具栏的宽度为
match_parent
,因此它占据了整个屏幕。 Try to use 尝试使用
android:orientation="vertical"
in the root layout 在根目录中
