java我的Android应用程序强制停止

Question

您好，当我点击按钮时，我的安卓应用程序遇到了一个问题。它停止了按钮的功能是使用PutExtra从EditText获取数据，并将数据和用户移动到另一个名为Check_inf

这是主类的xml代码：

Answer 1

我建议您将其转换为JSON，而不是ArrayList，以便于使用，下面是您应该做的事情

String json = new Gson().toJson(list);

然后将其添加到意图中

intent.putExtra(key,json);

现在在第二个活动中，执行以下操作以返回原始arrayList

ArrayList<String> listdata = new ArrayList<String>();     
JSONArray jArray = (JSONArray)getIntent.getExtra().getString(key).toString(); 
if (jArray != null) { 
   for (int i=0;i<jArray.length();i++){ 
    listdata.add(jArray.get(i).toString());
   } 
} 

现在只需阅读arrayList并返回代码
