你好我的Android应用程序遇到问题当我点击按钮它停止按钮的功能是使用PutExtra从Edittexts获取数据并将数据和用户移动到另一个名为 Check_inf的类
这是Main类的xml代码：

答案 0 :(得分：0)
请编辑如下代码并重新提交logcat
EditText phone = (EditText) findViewById(R.id.phone);
String _phone = phone.getText().toString();
Log.i("Before", _phone);
int phone2 = Integer.parseInt(_phone);
Log.i("After", String.ValueOf(phone2));
答案 1 :(得分：0)
我建议你将它转换为JSON而不是ArrayList，以便更容易使用，这是你应该做什么
String json = new Gson().toJson(list);
然后将其添加到意图
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());
}
}
现在只需读取arrayList并返回代码
