java - 如何在弹出窗口中设置textview？

Question

我正在尝试在弹出窗口中设置 TextView ，并且进入 TextView 弹出窗口的字符串来自 SOAP Web 服务调用。我在 logCat 和 PopUp 弹出窗口中看到字符串消息，但由于某种原因，我无法设置 TextView 来显示我的消息。我缺少什么。

谢谢你。

Answer 1

用这个

txtViewPop =(TextView) promptsView.findViewById(R.id.txtMsgAll);
                       ^^^^^^^^^^^^

而不是

txtViewPop = (TextView)findViewById(R.id.txtMsgAll);
