kayboard隐藏了editText，但是当键盘隐藏时，editText会出现在屏幕中间。与要求完全相反。我知道主要问题是我的自定义布局。请告诉我这个customlayout有什么问题。如果我用relativeLayoot替换customLayout，一切正常。但我必须使用这种布局。请帮我。

Answer 2

将所有视图都设为scrollview

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
         <LinearLayout
        android:id="@+id/title_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

        <include layout="@layout/header_layout" />
    </LinearLayout>       
     ..... 
    </RelativeLayout>
</ScrollView>

Answer 3

将整个相对布局包装在ScrollView内。

也

请注意，scrollview只能有1个子视图

这将是你最外层的相关布局。
