android ScrollView无法在片段中工作

问题描述

我正在做一个项目，该项目用碎片包裹导航抽屉， 在我的主页片段页面上，我添加了此布局。要将额外的数据添加到viewpager，Linear Layout和Gridview中，请使用Java代码。 我的问题是，Scrollview无法在我的home_fragment中工作。（仅GridiView滚动的不是完整的片段活动）。 我曾尝试使用嵌套的scrollview，但它也无法正常工作。 我提供了如下的xml和java代码，

fragment_home.xml

<ScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:scrollbarSize="0dp"
    android:fillViewport="true"
    >

<RelativeLayout
        android:id="@+id/HomeFragmentRelativeLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        >

        <androidx.viewpager.widget.ViewPager
            android:id="@+id/viewPage"
            android:layout_width="match_parent"
            android:layout_height="200dp"
            android:layout_margin="5dp"
            />
        <LinearLayout
            android:id="@+id/SliderDots"
            android:layout_below="@+id/viewPage"
            android:orientation="horizontal"
            android:gravity="center_vertical|center_horizontal"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginBottom="5dp"/>

        <GridView
            android:id="@+id/simpleGridView"
            android:layout_below="@+id/SliderDots"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:padding="15dp"
            android:gravity="center"
            android:numColumns="2"
            android:layout_margin="5dp"
            android:verticalSpacing="15dp"
            android:horizontalSpacing="15dp"
            />
    </RelativeLayout>
</ScrollView>

谢谢。

解决方法

您不能直接应用滚动视图，我希望这会起作用

$(search_result).each(function(index,result) {   // Not working this  console.log(result.username); });
