ListView控件与节头的问题 [英] ListView with section header problem
问题描述
你好我添加部分标题为我的ListView,还有网络上的一些方法。由于我使用simpleCursorAdapter来管理我的ListView,我采用了菲尔·博格尔的方法。 http://thebogles.com/blog/2010/02/科头换Android的列表视图/
Hi I'm adding section headers for my listView, there are few methods on the web. Since I'm using simpleCursorAdapter to manage my listView, I adopted phil bogle's method. http://thebogles.com/blog/2010/02/section-headers-for-android-listviews/
listAdapter.setViewBinder( new SimpleCursorAdapter.ViewBinder()
{
public boolean setViewValue(View view, Cursor cursor, int
columnIndex)
{
if (columnIndex == nDateIndex) {
if (isHeaderVisible(cursor)) {
view.setVisibility(View.VISIBLE);
prevDate = dateString;
((TextView) view).setText(dateString);
} else {
((TextView) view).setText("");
view.setVisibility(View.GONE);
}
return true;
}
return false;
}
});
这是LogCat中显示他们如何比较,而我向上滚动列表:
This is the LogCat shows how they compare while I scroll up the list:
09-06 11:06:43.460: INFO/System.out(563): Sun, 05 Sep 2010 11:41:53 (dateString)
09-06 11:06:43.460: INFO/System.out(563): Wed, 01 Sep 2010 21:58:06 (preDate)
09-06 11:06:43.460: INFO/System.out(563): 120.0 (record)
09-06 11:06:43.820: INFO/System.out(563): Sun, 05 Sep 2010 17:47:26 (dateString)
09-06 11:06:43.820: INFO/System.out(563): Sun, 05 Sep 2010 11:41:53 (preDate)
09-06 11:06:43.820: INFO/System.out(563): 112.0 (record)
正确的输出应该是:结果
孙,2010年9月5日结果
112结果
120
但是,当我向上滚动,则调用setViewValue第120和preDATE(显示以上)相比,它变成了:结果
孙,2010年9月5日结果
112结果
太阳,2010年9月5日结果
120
But when I scroll up, the setViewValue calls 120 first and compare with preDate(show above), it becomes:
Sun, 05 Sep 2010
112
Sun, 05 Sep 2010
120
那么,怎样才能让我创建固定头后段头?为什么滚动时setViewBinder被称为?对此有什么建议?谢谢!
So how can I make the section headers fixed after creating the headers? Why setViewBinder been called while scrolling? Any suggestions on this? Thanks!
推荐答案
您也可以看看这里很简单的项目:的 HTTP://$c$c.google.com/p/android-section-list/ 。灵感来自于iOS版的部分名单出来(出来,在iOS上的框)。
You might also take a look at very simple project here: http://code.google.com/p/android-section-list/. Inspiration came from iOS's section list (comes out of the box in iOS).
