OkHttpClient client;

client = new OkHttpClient.Builder()
        .connectTimeout(5, TimeUnit.SECONDS)
        .writeTimeout(5, TimeUnit.SECONDS)
        .readTimeout(5, TimeUnit.SECONDS)
        .build();

Request request22 = new Request.Builder()
        .url("http://www.goo.com/")
        .build();

Utils.myLog("-begin-");
Response response = null;
try {
    response = client.newCall(request22).execute();
    if (response.isSuccessful()) {
        Utils.myLog("-donw-");
    }
} catch (Exception e) {
    e.printStackTrace();
    Utils.myLog("-error-" + e.toString());
}

这是我的代码，我将超时设置为5秒，但是在“开始”之后仍然需要20秒才能收到“错误unknownhostexception”？为什么我的代码没用？我看了OKHTTP的源代码，默认超时是10秒（如果我是对的），我很困惑。

任何人都可以提供帮助，我非常感谢您。

我如何循环这个JSON：

[{
    "X": "54.6000621",
    "Y": "45.8360411",
    "Dates": [{
        "Date": "2000\/04\/26",
        "Time": "12:13:45"
    }, {
        "Date": "2000\/04\/26",
        "Time": "13:13:45"
    }, {
        "Date": "2000\/04\/26",
        "Time": "14:13:12"
    }, {
        "Date": "2000\/04\/26",
        "Time": "15:13:10"
    }, {

请有人帮我处理导航抽屉中的碎片,由于某种原因我无法让他们工作,所有代码看起来都正确.

这是源代码的链接.

我已经解析了一些XML数据Asynctask并将其打印在日志中,但每当我尝试将ArrayList数据复制到我的Activity中时,它总是保持为空.

这是代码,

public class MainActivity extends AppCompatActivity {

   static ArrayList<NewsItems>myData=new ArrayList<>();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ReadRss readRss = new ReadRss(this);
        readRss.execute();
       Log.d("TAG", String.valueOf(myData.size()));//This stays empty
    }


    public static void getData(ArrayList<NewsItems>items){
        for (int i=0; i<items.size(); i++){
            myData.add(items.get(i));
        }
    }
    class ReadRss extends AsyncTask<Void, Void, Void>{

         ArrayList<NewsItems>feedItems = new ArrayList<>();
        Context context;
        String address = "http://www.thedailystar.net/frontpage/rss.xml";
        ProgressDialog progressDialog;
        URL url;

        public ReadRss(Context context) {
            this.context = context;
            progressDialog = new ProgressDialog(context);
            progressDialog.setMessage("Loading..."); …

我无法覆盖onCreateDialog()方法Fragment.但它允许我覆盖Activity.

@Override
protected Dialog onCreateDialog(int id) {
    if (id == 999) {
        return new DatePickerDialog(this, myDateListener, year, month, day);
    }
    return null;
}
