手动调用 onListItemCLick
我正在使用 ListView 和 SimpleAdapter。一旦数据填充到其中，我想设置列表中的第一项。这可以通过单击屏幕上的列表项来完成。我想在填充列表后直接调用该方法，这样当您看到 UI 时它已经完成了。我唯一的问题是从 ListView 获取视图。我注意到它的子项都是空的，但 SimpleAdapter 中有项目。当我尝试获取这些项目时，它们不是视图，并且我无法匹配方法调用，
protected void onListItemClick(ListView l, View v, int position, long id)
因为我无法获取正确的视图。任何帮助将不胜感激。
I am using a ListView with a SimpleAdapter. Once data is populated into it I would like to set the first item in the list. This can be done by clicking on the list item on the screen. I want to just call the method directly after I populate the list so that when you see the UI its already done. My only problem is getting the View from the ListView. I noticed its children are all null but the SimpleAdapter has items in it. When I try to get those items they are not Views and I am not able to match the method call of
protected void onListItemClick(ListView l, View v, int position, long id)
because I cant get the right View. Any help would be appreciated.

经过大量搜索后，解决方案不是进行手动调用，而是重写适配器 getView 方法。这样我就可以更改背景颜色，而不必手动调用
onListItemClick()After lots of searching the solution is not to make a manual call but to override the adapter getView method. That way I can change the background color and not have to manually call
onListItemClick()
