在滚动条上隐藏工具栏
Hide Toolbar on scroll
我知道这个问题已经被问过很多次了,但我仍然无法让它工作。 app:layout_scrollFlags="scroll|enterAlways"参数是有的,不过我觉得跟嵌套有关系。我的 XML 文件如下:
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
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:background="@color/colorBG"
android:fitsSystemWindows="true"
android:id="@+id/mDrawerLayout"
android:layout_height="match_parent"
android:layout_width="match_parent"
tools:context=".MainActivity">
<android.support.design.widget.CoordinatorLayout
android:id="@+id/coordinatorLayout"
android:layout_height="match_parent"
android:layout_width="match_parent">
<LinearLayout
android:fitsSystemWindows="true"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:orientation="vertical">
<!-- App Bar-->
<android.support.v7.widget.Toolbar
android:background="@color/colorPrimary"
android:id="@+id/mToolbar"
android:layout_height="50dp"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:theme="@style/AppTheme.Toolbar"
app:layout_scrollFlags="scroll|enterAlways"/>
<FrameLayout
android:id="@+id/containerView"
android:layout_height="match_parent"
android:layout_width="match_parent">
</FrameLayout>
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.NavigationView
android:background="@color/colorPrimaryLight"
android:id="@+id/mNavigationView"
android:layout_gravity="start"
android:layout_height="match_parent"
android:layout_width="wrap_content"
app:headerLayout="@layout/header"
app:itemBackground="@color/colorPrimaryLight"
app:itemIconTint="@color/colorText"
app:itemTextColor="@color/colorText"
app:menu="@menu/drawer"/>
</android.support.v4.widget.DrawerLayout>
删除 LinearLayout
并添加 android.support.design.widget.AppBarLayout
作为 ToolBar
的容器。
将 FrameLayout
保持在 android.support.design.widget.AppBarLayout
之外。
将app:layout_behavior="@string/appbar_scrolling_view_behavior"
添加到FrameLayout
更新您的 activity_main.xml
如下:
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
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:background="@color/colorBG"
android:fitsSystemWindows="true"
android:id="@+id/mDrawerLayout"
android:layout_height="match_parent"
android:layout_width="match_parent"
tools:context=".MainActivity">
<android.support.design.widget.CoordinatorLayout
android:id="@+id/coordinatorLayout"
android:layout_height="match_parent"
android:layout_width="match_parent">
<!-- App Bar-->
<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true">
<!-- ToolBar-->
<android.support.v7.widget.Toolbar
android:background="@color/colorPrimary"
android:id="@+id/mToolbar"
android:layout_height="50dp"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:theme="@style/AppTheme.Toolbar"
app:layout_scrollFlags="scroll|enterAlways"/>
</android.support.design.widget.AppBarLayout>
<!-- Content-->
<FrameLayout
android:id="@+id/containerView"
android:layout_height="match_parent"
android:layout_width="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
</FrameLayout>
</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.NavigationView
android:background="@color/colorPrimaryLight"
android:id="@+id/mNavigationView"
android:layout_gravity="start"
android:layout_height="match_parent"
android:layout_width="wrap_content"
app:headerLayout="@layout/header"
app:itemBackground="@color/colorPrimaryLight"
app:itemIconTint="@color/colorText"
app:itemTextColor="@color/colorText"
app:menu="@menu/drawer"/>
</android.support.v4.widget.DrawerLayout>
希望这会有所帮助!
