摺疊狀態欄和底欄的工具欄問題。 Fitssystemwindows =「true」不起作用

Question

我無法讓我的CoordinatorLayout具有Collapsing工具欄和嵌套的ScrollView工作。

對CoordinatorLayout以外的任何其他設置fitssystemwindows =「true」不具有負面影響。 的應用主題具有屬性

<item name="android:windowTranslucentStatus">true</item> 

使狀態欄透明。

我的問題是： 1.圖像滾動得太慢，以至於半透明狀態欄採用藍色工具欄顏色（當工具欄不是100％展開時，ImageView是可見的）。

該系統的底酒吧是隱藏我NestedScrollView的一部分。

這是我的佈局：

<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.example.application.collapsingtoolbarexample.MainActivity"> 

<android.support.design.widget.AppBarLayout 
    android:layout_width="match_parent" 
    android:layout_height="250dp" 
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"> 

    <android.support.design.widget.CollapsingToolbarLayout 
     android:id="@+id/collapsing_toolbar" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     app:contentScrim="?attr/colorPrimary" 
     app:layout_scrollFlags="scroll|exitUntilCollapsed"> 

     <ImageView 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      android:src="@drawable/goslings" 
      android:scaleType="centerCrop" 
      app:layout_collapseMode="parallax" /> 

     <android.support.v7.widget.Toolbar 
      android:id="@+id/toolbar" 
      android:layout_width="match_parent" 
      android:layout_height="?attr/actionBarSize" 
      app:layout_collapseMode="pin"/> 

    </android.support.design.widget.CollapsingToolbarLayout> 

</android.support.design.widget.AppBarLayout> 

<android.support.v4.widget.NestedScrollView 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:background="#dfdddd" 
    app:layout_behavior="@string/appbar_scrolling_view_behavior"> 

    <LinearLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:orientation="vertical" 
     android:paddingTop="10dp" 
     > 

     <include layout="@layout/card_layout" /> 

     <include layout="@layout/card_layout" />

     <include layout="@layout/card_layout" /> 

     <include layout="@layout/card_layout" /> 

     <include layout="@layout/card_layout" /> 


    </LinearLayout> 

</android.support.v4.widget.NestedScrollView> 

Answer 1

您需要以適應系統的窗口（除了工具欄上的所有內容），還設置圖像不上高度CollapsingToolbar

android：fitsSystemWindows =「true」

所以最終的代碼將是

<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.example.application.collapsingtoolbarexample.MainActivity"> 

<android.support.design.widget.AppBarLayout 
    android:fitsSystemWindows="true" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"> 

    <android.support.design.widget.CollapsingToolbarLayout 
     android:id="@+id/collapsing_toolbar" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:fitsSystemWindows="true" 
     app:contentScrim="?attr/colorPrimary" 
     app:layout_scrollFlags="scroll|exitUntilCollapsed"> 

     <ImageView 
      android:layout_width="match_parent" 
      android:layout_height="250dp" 
      android:fitsSystemWindows="true" 
      android:src="@drawable/goslings" 
      android:scaleType="centerCrop" 
      app:layout_collapseMode="parallax" /> 

     <android.support.v7.widget.Toolbar 
      android:id="@+id/toolbar" 
      android:layout_width="match_parent" 
      android:layout_height="?attr/actionBarSize" 
      app:layout_collapseMode="pin"/> 

    </android.support.design.widget.CollapsingToolbarLayout> 

</android.support.design.widget.AppBarLayout> 

<android.support.v4.widget.NestedScrollView 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:background="#dfdddd" 
    app:layout_behavior="@string/appbar_scrolling_view_behavior"> 

    <LinearLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:orientation="vertical" 
     android:paddingTop="10dp" 
     > 

     <include layout="@layout/card_layout" /> 

     <include layout="@layout/card_layout" /> 

     <include layout="@layout/card_layout" /> 

     <include layout="@layout/card_layout" /> 

     <include layout="@layout/card_layout" /> 

     <include layout="@layout/card_layout" /> 

     <include layout="@layout/card_layout" /> 

     <include layout="@layout/card_layout" /> 

     <include layout="@layout/card_layout" /> 


    </LinearLayout> 

</android.support.v4.widget.NestedScrollView>
