API 小于 21 的 Tap 涟漪效应

Question

您好，我是 kotlin 的新手，我遇到了一个非常奇怪的问题。我有一个简单的 ListView 填充了一些子布局！ 我在 XML 中的 ListView 标记是：

          <ListView
            android:id="@+id/invoicesList"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:divider="@null"
            android:dividerHeight="0dp"/>

我的适配器是：

class InvoicesListAdapter(context: Context, activity: Activity, resource: Int, list: ArrayList<InvoicesListModel>) : ArrayAdapter<InvoicesListModel>(context, resource, list) {

    var list: ArrayList<InvoicesListModel> = list
    var activity: Activity? = null

    init {
        this.activity = activity
    }

    private class ViewHolder(row: View?) {
        var serviceName: BakcellTextViewNormal? = null
        var endirimValue: BakcellTextViewNormal? = null
        var miqdarValue: BakcellTextViewNormal? = null
        var vahidValue: BakcellTextViewNormal? = null
        var mablaqValue: BakcellTextViewNormal? = null
        var camiValue: BakcellTextViewNormal? = null

        init {
            this.serviceName = row?.findViewById(R.id.serviceValue)
            this.endirimValue = row?.findViewById(R.id.endirimValue)
            this.miqdarValue = row?.findViewById(R.id.miqdarValue)
            this.vahidValue = row?.findViewById(R.id.vahidValue)
            this.mablaqValue = row?.findViewById(R.id.mablaqValue)
            this.camiValue = row?.findViewById(R.id.camiValue)
        }//init ends
    }// class ViewHolder ends

    override fun getView(position: Int, convertView: View?, parent: ViewGroup): View {
        val view: View?
        val viewHolder: ViewHolder
        if (convertView == null) {
            val inflater = context?.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater
            view = inflater.inflate(R.layout.invoices_list_layout, null)
            viewHolder = ViewHolder(view)
            view?.tag = viewHolder
        } else {
            view = convertView
            viewHolder = view.tag as ViewHolder
        }

        var listModel = getItem(position)
        viewHolder.serviceName!!.text=listModel.serviceName
        viewHolder.miqdarValue!!.text=listModel.miqdarValue
        viewHolder.vahidValue!!.text=listModel.vahidValue
        viewHolder.mablaqValue!!.text=listModel.mablaqValue
        viewHolder.endirimValue!!.text=listModel.endirimValue
        viewHolder.camiValue!!.text=listModel.camiValue

        //send arrow click

        return view as View
    }//getview ends
}//class ends

我的适配器/ListView 项目布局是：

    <View

        android:layout_below="@+id/ripple"

        android:layout_marginRight="@dimen/_45sdp"
        android:background="@color/colorSeperator"></View>
</RelativeLayout>

问题是当我点击 id=ripple 的相对布局时，我想显示波纹！ 我知道我可以设置：

android:background="?android:attr/selectableItemBackground"
android:clickable="true"

关于所需的布局！ 但是，每当我在 id=ripple 的相对布局上注册任何点击侦听器时，它都会停止显示波纹效果！

我正在使用 Android 5.0 Lollipop 的 LG G3 上对其进行测试，我希望 Android 版本 19+ 的 Android 设备应该显示涟漪效应。

我必须使用

    android:background="?android:attr/selectableItemBackground"
    android:clickable="true"

为了显示连锁反应，有人可以帮我找出我做错了什么吗？提前致谢！

Answer 1

试试?attr/selectableItemBackgroundBorderless
