海兰!
我有一个Json对象:
HttpResponse responsePOST = client.execute(post);
HttpEntity resEntity = responsePOST.getEntity();
final JSONObject jObject = new JSONObject(EntityUtils.toString(resEntity));
Log.e("test", jObject.toString());
日志:
{"responseData":null,"responseStatus":200,"responseDetails":null}
码:
Log.e("test", String.valueOf(jObject.getInt("responseStatus")))`;
日志:
200
从Json获取Int:
if (jObject.getInt("responseStatus")== 200)
{
Toast toast ;
toast = Toast.makeText(getApplicationContext(), "OK", 500);
toast.show();
finish();
}
else
{
Log.e("else", "else");
//dismissDialog(DIALOG_LOADING);
if (jObject.getInt("responseStatus")== 500)
{
throw new Exception("Server Error");
}
else if (jObject.getInt("responseStatus")== 400)
{
throw new Exception("Wrong User/Password");
}
else
{
throw new Exception();
}
}
//pd.dismiss();
} catch (Exception e) {
Log.e("catch", "catch"); …海兰!
我的Thread.interrupt不起作用.
代码(我们是全球的):
//Call
us = new UpdateState(params, hup);
us.start();
//Interupt
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId()== R.id.stopthread)
{
Log.e("Kill", "Kill");
us.interrupt();
}
return super.onOptionsItemSelected(item);
}

我有一些初学者问题:
头文件和导航栏是否应在header.php中排除并使用echo打印出来？
应该在php中的echo中设计标签(如:)<a>1 Test test</a>或仅返回数据
我的主要问题是我不知道如何制作清晰的结构.在哪里做出正确的设计(在php中打印出来？)

我想在c#中创建一个cardgame.调试器总是抛出一个NullPointerException.但是var卡不是null(它在调试期间显示了一个值)问题必须在cards.add()中.
我的代码:
namespace Uno_Logic
{
class CardStack
{
private List<Card> cards;
public void Cardstack()
{
cards = new List<Card>();
}
public void fillCardstack ()
{
for (Card_Value value = Card_Value.One; value <= Card_Value.DrawTwo; value++)
{
for (Card_Colour colour = Card_Colour.Yellow; colour < Card_Colour.Black; colour++)
{
Card card = new Card(colour, value);
Card card2 = new Card(colour, value);
cards.Add(card); //**here throws the debugger the Exception**
cards.Add(card2);
}
}
}
}
}
请帮忙!
