Android在清单上滑动

Question

有没有人有一个简单的ListActivity示例，该示例在列中显示Textviews，当您从左向右滑动时，会在新视图中看到该行？这就是说编辑该行的数据或显示该行的更多详细信息。请不要引用代码幕府将军或其他网站，因为我已经用Google搜索过，也没有看到这个答案。

Answer 1

这是一个非常简化的版本，它使用两个侦听器（onTouch用于滑动检测，onClickIem用于项目单击检测）使用isSwipe标志停止onClickItemListener，直到其确认不是滑动在检测到点击不是第一次刷卡的情况下&nbsp; &nbsp; &nbsp; &nbsp; listView.setOnItemClickListener(new OnItemClickListener() {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; @Override&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if(!isSwipe)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; adapter.increase(arg2);&nbsp;
