我的应用程序有一个客户端数据列表视图。 listView中的每一行都将包含name，address，telNo等。我从webcall获取数据，然后使用要返回适配器的数据填充ArrayList。
当用户单击列表中的某行时，然后在适配器的onClick中，我获取电话号码并启动启动拨号器活动的意图。这一切都运作良好。
客户端的telno总是来自网络摄像头，但在视图中我有逻辑确定它是否显示。有些公司不希望显示客户编号，而其他公司则显示。
如何判断保存数字的TextView是否在运行时显示在视图中？我设置了一个标签，我传递给onclick，其中listView中的行已被点击，但我怎么能使用像
这样的东西if(Textview.isShown)
在onClick里面？我最终想要的是，如果文本视图显示保存数字，那么用户可以单击以拨打拨号器，否则拨号器将不拨号码（即使它出现在列表中，只是没有显示）。
先谢谢马特。

答案 0 :(得分：1)
您需要在列表项上单击
初始化textview @Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
TextView tv = (TextView)view.findViewById(R.textView1);
if (tv.getVisibility() == View.VISIBLE) {
// Its visible
} else {
// Either gone or invisible
}
}
});
点击项目后，您可以将视图作为onItemClick的参数。因此，使用视图对象初始化textview
TextView tv = (TextView)view.findViewById(R.textView1);
然后使用textview tv进行操作。
