问题描述

我有一个 CoordinatorLayout，在 AppBarLayout 内有一个 Toolbar 和一个 TabLayout.此外，我在 CoordinatorLayout 内但在 ViewPager 之外有一个 ViewPager.

问题是 ViewPager 的 高度大于实际可用的高度，导致我的 Fragment 中的一些视图被剪切.

<?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"android:layout_width="match_parent"android:layout_height="match_parent"android:background="@color/lightGray"android:fitsSystemWindows="true"> 
 解决方案 
可能的 hack 可以是添加 与工具栏相同的底部边距，即 
?attr/actionBarSize .您甚至可以摆弄其他可能的 ui hacks 边距，以获得最佳结果.
I have a CoordinatorLayout with a Toolbar and a TabLayout inside the AppBarLayout. Additionally, I have a ViewPager inside the CoordinatorLayout but outside the ViewPager. 

The problem is that the ViewPager's height is bigger than what is actually available, resulting in some views from my Fragment being cut.
<?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"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/lightGray"
    android:fitsSystemWindows="true">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/app_bar_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar2"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            app:popupTheme="@style/AppTheme.PopupOverlay"
            app:layout_scrollFlags="scroll|enterAlways"/>

        <android.support.design.widget.TabLayout
            android:id="@+id/tabLayout"
            android:scrollbars="horizontal"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:fillViewport="false"/>

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

    <android.support.v4.view.ViewPager
        android:id="@+id/pager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

</android.support.design.widget.CoordinatorLayout>
And this what I mean when I say that the ViewPager has the wrong height.

  
 解决方案 
A possible hack can be adding same bottom margin as toolbar which is 

?attr/actionBarSize . You can even fiddle around with other possible ui hacks of margins to give you best result.
