目标是想让Toolbar不被DrawerLayout的NavigationView遮盖,一直显示。
以下代码运行于Android Studio 2.1.2, 手机5.1.1
<!--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:id="@+id/drawer_layout" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true" tools:openDrawer="start"> <include layout="@layout/content_main" android:layout_width="match_parent" android:layout_height="match_parent" /> <android.support.design.widget.NavigationView android:id="@+id/nav_view" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_gravity="start" android:fitsSystemWindows="true" app:headerLayout="@layout/nav_header_main" app:menu="@menu/activity_main_drawer" /> </android.support.v4.widget.DrawerLayout> <!--content_main.xml--> <?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:showIn="@layout/activity_main" tools:context="com.hooking.note.MainActivity"> <android.support.design.widget.AppBarLayout 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" app:popupTheme="@style/AppTheme.PopupOverlay" /> </android.support.design.widget.AppBarLayout> <RelativeLayout android:id="@+id/fg_main_list" android:layout_width="match_parent" android:layout_height="match_parent" app:layout_behavior="@string/appbar_scrolling_view_behavior"/> <android.support.design.widget.FloatingActionButton android:id="@+id/fab" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="bottom|end" android:layout_margin="@dimen/fab_margin" android:background="?attr/colorPrimary" android:src="@drawable/ic_add_white_24dp" app:layout_behavior="@string/floating_action_button_behavior" /> </android.support.design.widget.CoordinatorLayout>
主题是android studio项目模板默认的
<style name="AppTheme.NoActionBar"> <item name="windowActionBar">false</item> <item name="windowNoTitle">true</item> <item name="android:windowDrawsSystemBarBackgrounds">true</item> <item name="android:statusBarColor">@android:color/transparent</item> </style> <activity android:name=".MainActivity" android:theme="@style/AppTheme.NoActionBar" />
运行结果如下:
<!-- activity_main_2.xml --> <?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.hooking.note.MainActivity"> <android.support.design.widget.AppBarLayout 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" app:layout_scrollFlags="scroll|enterAlways" app:popupTheme="@style/AppTheme.PopupOverlay" /> </android.support.design.widget.AppBarLayout> <include layout="@layout/content_main_2" /> <android.support.design.widget.FloatingActionButton android:id="@+id/fab" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="bottom|end" android:layout_margin="@dimen/fab_margin" android:background="?attr/colorPrimary" android:src="@drawable/ic_add_white_24dp" app:layout_behavior="@string/floating_action_button_behavior" /> </android.support.design.widget.CoordinatorLayout> <!-- content_main_2.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:id="@+id/drawer_layout" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="false"//注1 app:layout_behavior="@string/appbar_scrolling_view_behavior" tools:openDrawer="start"> <RelativeLayout android:id="@+id/fg_main_list" android:layout_width="match_parent" android:layout_height="match_parent"/> <android.support.design.widget.NavigationView android:id="@+id/nav_view" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_gravity="start" android:fitsSystemWindows="false"//注2 app:headerLayout="@layout/nav_header_main" app:menu="@menu/activity_main_drawer" /> </android.support.v4.widget.DrawerLayout>
主题不变,运行结果如下:
发现NavigationView的顶部有一与状态栏高度相等的遮罩层,请问怎样去掉这部分遮罩层的阴影。
试过,修改DrawerLayout和NavigationView的布局属性;以及从以下代码涉及到颜色的函数着手修改,都没有效果
修改activity_main_2.xml、content_main_2.xml中DrawerLayout 【注1】 和NavigationView【注2】的 android:fitsSystemWindows="false"
由false改为true,就出现了以下结果:可以看到内容区也多了状态栏同等高度的遮罩层阴影
付费偷看金额在0.1-10元之间
CoordinatorLayout里面套一个LinearLayout呢
把Toolbar和DrawerLayout放进去
