android mapview点击问题

[S529586243]

我的地图上有许多标记的点,点击每个点时会弹出一个view,当我第一次加载地图的时候显示所有的标记的点,这个时候点击任何点并且弹出view都是没问题的,这时我随便点击地图中的一个标记,弹出一个view,当我输入查询条件,显示部分标记点的时候,如果再点击地图上的任何位置,都会报错,

你在做操作的时候出错了，ArrayIndexOutOfBoundsException
你最好检查下你的操作代码，

感觉是不是资源加载太多出问题了，是不是弱引用

我晓得是索引越界问题,但是不知道为什么会越界,难道是我查询的时候没有清空什么东西吗?
弱弱的问一句:什么是"弱引用"

等我明天上班帮你解决，困了睡觉

同被此问题困扰 ，很郁闷的问题

[samking1124]

找到一个解决办法
private void doPopulate(){
setLastFocusedIndex(-1);
populate();
}
在原来调用populate()方法地方调用 目前测试未发现问题
