java.lang.IllegalArgumentException: Wrong state class, expecting View State but received class cn.etouch.ecalendar.waterfallview.StaggeredGridView$GridListSavedState instead. This usually happens when two views of different type have the same id in the same hierarchy. This view‘s id is id/refresh_gridView. Make sure other views do not use the same id.
按照Log的提示,是id起了冲突。但是我经过仔细查看XML布局文件,并没有起冲突的ID,事实上,在xml布局文件中经常有重名的id。网上还有一些说通过clean项目,这个也解决不了问题。
我遇到的情形是:FragmentA 中包括FragmentA1,FragmentA2,FragmentA3,FragementA3中有一个自定义的GridView,当A1,A2和A3之间切换时,程序就会崩溃,并报上述的错误。
id相同?确实可能是ID相同。因为,当A1,A2和A3切换的时候,将A3的gridView状态保存了,当然id也保存下来了。下次再切换到A3就可能出现id相同的情形。(不知道理解的对不对?)
这时候需要重写GridView中的onRestoreInstanceState函数:
默认:
@Override
protected void onRestoreInstanceState(Parcelable state) {
super.onRestoreInstanceState(state); }
修改为:
@Override
protected void onRestoreInstanceState(Parcelable state) {
try {
super.onRestoreInstanceState(state);
}catch (Exception e) {}
state=null;
}
再次运行程序,问题得到解决
