问题描述

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="http://schemas.android.com/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="http://schemas.android.com/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="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">

    <android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/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..
