片段中的Android gridview无法滚动

问题描述 投票：0回答：1

我有一个名为products的页面。加载页面时，它显示productsfragment。这个片段有一个RecyclerView没有任何问题。在选择产品时，会打开一个新片段并显示产品价格片段列表。这个片段有一个RecyclerView，这里的滚动不起作用。

我尝试过gridview和cardview，但它们也没有滚动。我在滚动视图或嵌套滚动视图中尝试了gridview，它们也没有滚动。

这是我的片段与RecyclerView不滚动

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/sorderfragment_step1_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".Activities.OrderSelect.Fragments.ProductSingleOrder.SOrderFragment_Step1">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/gvProductPrices"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
</LinearLayout>

和我的RecyclerView项目视图

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="200dp"
    android:layout_height="200dp"
    android:gravity="center"
    android:maxHeight="200dp"
    android:minHeight="200dp"
    android:background="@layout/border2"
    android:padding="0dp"
    android:orientation="vertical">

    <TextView
        android:id="@+id/txtPriceName"
        android:layout_width="match_parent"
        android:layout_height="100dp"
        android:layout_marginBottom="8dp"
        android:layout_marginEnd="8dp"
        android:layout_marginRight="8dp"
        android:layout_marginTop="8dp"
        android:gravity="center"
        android:text="Kucuk Boy Whopper"
        android:textSize="30sp"
        android:textStyle="bold"
        app:layout_constraintBottom_toTopOf="@+id/constraintLayout4"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <android.support.constraint.ConstraintLayout
        android:id="@+id/constraintLayout4"
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:layout_marginBottom="8dp"
        android:layout_marginEnd="8dp"
        android:layout_marginRight="0dp"
        android:background="#000000"
        app:layout_constraintBottom_toTopOf="@+id/txtPrice"
        app:layout_constraintEnd_toEndOf="parent">

    </android.support.constraint.ConstraintLayout>

    <TextView
        android:id="@+id/txtPrice"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="4dp"
        android:layout_marginEnd="8dp"
        android:layout_marginRight="8dp"
        android:gravity="center"
        android:text="14.99"
        android:textColor="#000000"
        android:textSize="24sp"
        android:textStyle="bold"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent" />

</LinearLayout>

和我的适配器

class PriceAdapter(val priceList : List<ProductPrice>,
                   val context: Context) : RecyclerView.Adapter<ViewHolder>() {
    override fun onCreateViewHolder(p0: ViewGroup, p1: Int): ViewHolder {
        return ViewHolder(LayoutInflater.from(context).inflate(R.layout.gv_product_prices, p0, false))
    }

    override fun getItemCount(): Int {
        return priceList.size
    }

    override fun onBindViewHolder(p0: ViewHolder, p1: Int) {
        val price = priceList[p1]
        p0.txtPriceName.text = price.getDescription()
        p0.txtPriceName.isAllCaps = true
        p0.txtPrice.text = BaseHelper.getNumericStr(price.getPrice())
    }

}

class ViewHolder (view: View) : RecyclerView.ViewHolder(view) {
    val txtPriceName = view.txtPriceName!!
    val txtPrice = view.txtPrice!!
}

和我的片段代码

    class SOrderFragment_Step1 : Fragment() {
    private var _priceRepository = ProductPriceRepository(OrderRepository.orderSelect!!)
    private var priceAdapter: PriceAdapter? = null
    private var prices: List<ProductPrice>? = null

    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?,
                              savedInstanceState: Bundle?): View? {
        return inflater.inflate(R.layout.fragment_sorder_step1, container, false)
    }

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        configurePrices()
    }

    private fun configurePrices() {
        prices = _priceRepository.getPriceByProductId(OrderRepository.currentProduct!!.getId())
        gvProductPrices.layoutManager = GridLayoutManager(OrderRepository.orderSelect!!, 2)
        gvProductPrices.adapter = PriceAdapter(prices!!, this, OrderRepository.orderSelect!!)
    }

    fun priceSelect(price: ProductPrice) {
        Toast.makeText(OrderRepository.orderSelect!!, price.getDescription(), Toast.LENGTH_LONG).show()
    }

}

并且像这样改变片段

val manager = this.fragmentManager!!.beginTransaction()
            manager.setCustomAnimations(android.R.anim.fade_in, android.R.anim.fade_out)
            manager.replace(R.id.fragmentProductSteps, SOrderFragment_Step1(), "detailFragment").commit()

我该如何解决这个问题？

建议：为什么使用网格视图并将适配器设置为其他方法和常用方法。

这是使用Recycler视图并将其布局管理器设置为GridLayout管理器

单行以下将完成您的工作

recyclerView.setLayoutManager(new GridLayoutManager(this, numberOfColumns));
