片段中的Android gridview无法滚动

标签： android gridview mobile kotlin

我有一页叫做产品。页面加载后显示产品碎片。这个片段有一个RecyclerView，没有任何问题。选择产品后，将打开一个新片段，并显示产品价格片段列表。该片段只有一个RecyclerView，无法在此处滚动。

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

这是我的RecyclerView片段，它没有滚动

<?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>

及其我的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()
    }

}

还有这样的片段更改

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()

如何解决此问题？

1 个答案:

答案 0 :(得分：3)

建议：为什么要使用网格视图并在有其他方法和常用方法的地方为其设置适配器。

将使用回收站视图并将其布局管理器设置为GridLayout管理器

单行下面将使您的工作完成

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