Question

我想在android应用kotlin的listview中添加文本和图像。我已经成功解析了listview中的文本，但是无法添加图像。我也正在获取图像的url，例如url / image.jpeg，但是不知道如何在override fun getView的imageview中添加图像。

代码：

  override fun getView(position: Int, convertView: View?, parent: ViewGroup?): View {

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

        val CallsingID = view.findViewById(R.id.callsign_id) as AppCompatTextView
        val StatusID = view.findViewById(R.id.airline_id) as AppCompatTextView
        val LogoAriline = view.findViewById(R.id.imageView) as ImageView


        // l have to add image here to get result 

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

        return view

}

Answer 1

var o = p.GetValue(this,null);
EventInfo eventInfo = t.GetEvent("CollectionChanged", BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance);

var handler = new Action<object, NotifyCollectionChangedEventArgs>((s, a) => { Console.WriteLine("Changed + " + this.TestInt.ToString()); });

Delegate del = Delegate.CreateDelegate(eventInfo.EventHandlerType, handler.Target, handler.Method);

eventInfo.AddEventHandler(o, del);

或另外实现Picasso http://square.github.io/picasso/

并使用：

LogoAriline.setImageResource(R.drawable.drawableName)

Answer 2

您可以使用Glide库

<sys/auxv_386.h>

Answer 3

我找到了解决方案，他的工作正常，没有任何错误。

Picasso.get().load(list[position].logo).into(LogoAriline)
