      }

现在我试着去拥有它，因此列表显示

地址 城市，省

我能得到它的工作我的其他名单，但我没有与这一个运气。我曾尝试添加一个字符串，如下所示

String[] ct_listinfo = (ct_address + "\n" + ct_city + ", " + ct_province); 

，改变

setListAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,ct_address)); 

到

setListAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,ct_listinfo)); 

，但是这并不能帮助我失去了什么？

Answer 1

您试图连接字符串数组而不是字符串。您需要分别连接每个字符串：

String[] ct_listinfo=new String[jArray.length()]; 

for(int i=0;i<jArray.length();i++){ 
    // all your code 
    ct_listinfo[i] = new String (ct_address[i] + "\n" + ct_city[i] + ", " + ct_province[i]); 
}
