Question

我在我的应用中创建了带有选项卡的滑动视图，并使用listview作为我的数据json url。我的应用程序运行正常，但问题在于当我午餐应用程序空着活动时。

如下所示，这是java类，我在其中处理选项卡中的操作。

主要活动：

package com.iraqairoirt.iraqairports


import android.annotation.SuppressLint
import android.support.v7.widget.AppCompatTextView
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import android.widget.BaseAdapter

class ListAdapte (val context: fragment_Dep, val list: ArrayList<FlightShdu>): BaseAdapter() {

    @SuppressLint("ViewHolder")
    override fun getView(position: Int, convertView: View?, parent: ViewGroup?): View {

        val view : View = LayoutInflater.from(context.context).inflate(R.layout.row_layout,parent,false)

        val CallsingID = view.findViewById(R.id.callsign_id) as AppCompatTextView
        val StatusID = view.findViewById(R.id.status_id) as AppCompatTextView

        CallsingID.text = list[position].Callsign.toString()
        StatusID.text = list[position].Status

        return view
    }

    override fun getItem(position: Int): Any {
        return list [position]
    }

    override fun getItemId(position: Int): Long {
        return position.toLong()
    }

    override fun getCount(): Int {
        return list.size
    }
}

ListAdapte

<?php echo getBhQuery('search','JobOrder','isOpen:true','id,title,categories,dateAdded,externalCategoryID,employmentType,customText12', null, 10, '-dateAdded');?>

当我用ListView打开片段时有空白屏幕吗？

选项卡式活动Kotlin中未显示listview
