已升级应用程序以使用Material Design- Theme.AppCompat.Light.NoActionBar ,工具栏,而不是 ActionBar 等.
Have upgraded app to use Material Design - Theme.AppCompat.Light.NoActionBar, Toolbar instead of ActionBar etc..
有问题.在APi> = 21
And have a problem. Bottom content become to be hidden under soft NavigationBar (see picture below) on devices with APi >= 21
找到解决此问题的方法:
Have found solution to fix this:
在 values-v21/styles.xml
<style name="MyTheme" parent="Theme.AppCompat.Light.NoActionBar"> ... <item name="colorPrimaryDark">@color/green</item> <item name="android:windowDrawsSystemBarBackgrounds">false</item> </styles>如果选项< item name ="android:windowDrawsSystemBarBackgrounds"> false</item> -底部内容可见,但是 statusbar 变成黑色.我无法将颜色更改为 colorPrimaryDark (在我的情况下为绿色)
if option <item name="android:windowDrawsSystemBarBackgrounds">false</item> - bottom content is visible, but statusbar become completely black. I cant change color to colorPrimaryDark (green in my case)
如果选项< item name ="android:windowDrawsSystemBarBackgrounds"> true</item> -底部内容不可见,并且状态栏是预期的.
if option <item name="android:windowDrawsSystemBarBackgrounds">true</item> - bottom content is invisible, and statusbar is green, as expected.
我希望状态栏为彩色(绿色)和可见的底部内容.工具栏可能是问题所在.它会压低内容吗?
I want to have statusbar colored(green) and visible bottom content.. Probably, issue is with toolbar. Is it pushes content down?
有什么建议吗?
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
< item name ="android:windowDrawsSystemBarBackgrounds"> false</item>
更新:
正如建议的@azizbekian一样,我已将用于碎片的容器替换为CoordinatorLayout(在FrameLayout之前),并应用了 android:fitsSystemWindows ="true" 在这种情况下,底部面板可见,但底部不可见.目标是将按钮保持在底部...
As suggested @azizbekian, I've replaced container for fragmets to CoordinatorLayout(before FrameLayout) and applied android:fitsSystemWindows="true" In this case bottom panel is visible, but not at the bottom.. Goal is to keep buttons athe bottom...
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="schemas.android/apk/res/android" android:layout_height="match_parent" android:layout_width="match_parent" android:orientation="vertical"> <include layout="@layout/toolbar"/> <!-- The main content view --> <android.support.design.widget.CoordinatorLayout android:id="@+id/content" android:fitsSystemWindows="true" android:layout_width="match_parent" android:layout_height="match_parent" /> </LinearLayout>屏幕布局:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout android:layout_height="match_parent" android:layout_width="match_parent" android:orientation="vertical" xmlns:android="schemas.android/apk/res/android"> <FocusableScrollView android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1" android:id="@+id/order_editor_layout" android:fillViewport="true"> <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content"> <include android:layout_width="match_parent" android:layout_height="match_parent" layout="@layout/o_e_content" android:layout_alignParentRight="true" android:layout_alignParentEnd="true" android:layout_alignParentStart="true" android:layout_alignParentLeft="true"/> </RelativeLayout> </FocusableScrollView> <include android:layout_width="match_parent" android:layout_height="wrap_content" layout="@layout/oe_bottom_pane"/> </LinearLayout>这是结果:
UPDATE#2
活动布局:
<?xml version="1.0" encoding="utf-8"?> <android.support.design.widget.CoordinatorLayout xmlns:android="schemas.android/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true"> <android.support.v7.widget.Toolbar xmlns:android="schemas.android/apk/res/android" xmlns:app="schemas.android/apk/res-auto" android:id="@+id/my_toolbar" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" android:background="?attr/colorPrimary" android:elevation="4dp" android:theme="@style/ActionBarTheme" app:popupTheme="@style/ThemeOverlay.AppCompat.Light" /> <!-- The main content view --> <FrameLayout android:id="@+id/content" android:layout_width="match_parent" android:layout_height="match_parent"/> </android.support.design.widget.CoordinatorLayout>将 LinearLayour 替换为 CoordinatorLayout 作为活动的根.作为内容的根元素,我保留了 FrameLayout .将 android:fitsSystemWindows ="true" 应用于 CoordinatorLayout .这样,所有内容都会稍微向上移动,一部分会放在工具栏下方(您可以在下面的图像中看到-顶部元素是带+和-的圆圈.但是在以前的图像上顶部是文本.)关于底部元素(按钮面板)-仍位于导航栏下方,但也略微向上移动.我已标记 android:background ="@ color/red" 以便于识别此面板的位置.
Replaced LinearLayour with CoordinatorLayout as root for activity. As root element for content I've keep FrameLayout. Applied android:fitsSystemWindows="true" to CoordinatorLayout. This way, all content was slightly moved up and part of placed below the toolbar(you can see on image below - top elements are circle with + and - symbold. But on previous images there are text on the top.) Regarding bottom elements (buttons panel) - still placed below navigation bar but also slightly moved up. I've marked android:background="@color/red" to easier recognize position of this panel.
似乎,我们走对了路.我们所需要的-解决问题-为什么内容移动到工具栏下方.如果tolbar将成为顶部ui,则按钮将可见..
Seems, we are on the right way. All we need - to resolve problem - why content moved below the toolbar.. If tolbar will be top ui elemnt, buttons will be visible..
推荐答案
将 android:fitsSystemWindows ="true" 应用于根视图.
