我有20个按钮和GridView的Activity。 一键清除GridView和其他添加到GridView的不同值。 有时我按1-Add，2-Clear，3-Add但看到按钮清除被推（橙色）并执行1-Add，2-Add，3-Clear。 一些时间按钮清除变得长时间按，并且根本不回答，但其他按钮工作。 这怎么可能？ 我的活动：

答案 0 :(得分：0)
要解决此问题，甚至缩小问题范围，您需要重构代码。每次点击都会发生一系列事情，你可能会淹没点击。你是否在点击之间留出足够的时间？
另外，请考虑使方法通用，例如
if(i.getExtras().containsKey("Napitki"))
{
ArrayList<String> NapitkiList=new ArrayList<String>();
NapitkiList=i.getExtras().getStringArrayList("Napitki") ;
for(String item : NapitkiList)
{
String Art=Asortiment.GetArtByName(item);
String [] np=Asortiment.GetNamePriceByArt(Art);
ButtonOn (np[0],np[1]);
}
}
if(i.getExtras().containsKey("Zhevacki"))
{
ArrayList<String> ZhevackiList=new ArrayList<String>();
ZhevackiList=i.getExtras().getStringArrayList("Zhevacki") ;
for(String item : ZhevackiList)
{
String Art=Asortiment.GetArtByName(item);
String [] np=Asortiment.GetNamePriceByArt(Art);
ButtonOn (np[0],np[1]);
}
}
