Question

我正在使用okHttp 我的网址没问题但是当我在模拟器或真实设备上运行该应用程序时，它永远不会显示任何错误。但它没有记录天气数据。

Mainactivity.java

   package com.buckydroid.droidweather;

import android.app.DownloadManager;
import android.os.AsyncTask;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;

import java.io.IOException;

import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

public class MainActivity extends AppCompatActivity {
    public static String responsedata;
    private static final String TAG = "MainActivity";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        TextView text = (TextView)findViewById(R.id.text) ;

        new AsyncTask<Void, Void, String>()  {
            @Override
            protected String doInBackground(Void... params) {
                OkHttpClient client = new OkHttpClient();
                Request request = new Request.Builder().url("https://api.forecast.io/forecast/11f696255d54c7cea3d097a6338bbaed/37.8267,-122.423").build();
                try {

                    Response response = client.newCall(request).execute();

                    responsedata = response.body().toString();
                    Log.d(TAG,responsedata);
                    return  responsedata;
                } catch (IOException e) {
                    e.printStackTrace();
                }
                return responsedata;
            }
        }.execute();



    }
}

这个片段：

            Log.d(TAG,responsedata);
            responsedata = response.body().string();

它应该是相反的顺序接下来，您需要根据String来回doInBackground AsyncTask<Void, Void, String> 另外，常见的做法是扩展AsyncTask并使用自己的类。

无法在日志中查看天气数据
