Android 从具有按钮的ListView获取列表项的位置

我想在listView中单击该项。我在网上搜索了很多，找到了一些解决方案，其中使用扩展适配器类创建了一个新类，然后调用了getView（）方法，但它对我不起作用，因为我正在填充数据库中的数据。 我想我的文本视图也可以点击，但我被卡在按钮上，所以如果你可以帮助，那么请帮助我点击按钮和文本视图

这是我的listView xml，其中onClick=“navigateToMap”

您正试图使用getText（）从XML中指定的Textview获取文本。虽然这对于布局来说很好，但是一个列表视图将有许多-几十个，甚至数百个相同的文本视图，因为您将为每个列表项膨胀该视图。navigateToMap（）不知道要从哪个文本视图中提取

您应该使用onItemClickListener列出单击，并使用视图调用navigateToMap 点击了

大概是这样的：

 item.setOnItemClickListener(new OnItemClickListener() {
 public void onItemClick(AdapterView<?> parent, View view, int position, long id) {            

               navigateToMap(view)   // this passes the view you inflated and filled         
                                     //with data, bot just the XML that defines 
                                     //what it looks like

            }
     });

当我在navigate方法中执行此操作时，我没有得到getChildAt（）方法，如何获得position？当position变量调用此方法TextView txt1=（TextView）view.getChildAt（某些索引）时，我应该传递position变量吗
