使 activity 的片段像一页长页一样滚动

Question

我有一个 activity，它由垂直线性布局中的几个片段（全部包含列表视图）组成。现在，每个列表本身都是可滚动的，但我想要的是整个 activity 滚动，就好像所有内容都只是一个长页面。

我尝试在要添加片段的容器周围添加一个滚动视图，检查每一个似乎相关的属性，但无济于事。我怎样才能使这项工作？

activity 布局的

XML

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout (...)
    app:layout_behavior="@string/appbar_scrolling_view_behavior" >

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="center_horizontal"
        android:layout_alignParentEnd="true"
        android:layout_alignParentStart="true"
        android:fillViewport="true"
        android:touchscreenBlocksFocus="true"
        android:importantForAccessibility="yes">

        <LinearLayout
            android:id="@+id/fragment_container"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">
        </LinearLayout>

    </ScrollView>

</RelativeLayout>

Answer 1

public class ListViewForScrollView extends ListView {
    public ListViewForScrollView(Context context) {
        super(context);
    }

    public ListViewForScrollView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public ListViewForScrollView(Context context, AttributeSet attrs,
    int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    /**
     * rewrite this method to let listview be suitable for scrollview.
     * after that, you can use ListViewForScrollView in ScrollView
     */
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
    MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, expandSpec);
    }
}
