之前实现过了天气预报的功能但是真的好丑真的只是实现功能所以上一篇博客也没有贴出图片这次相对于第一个首先是界面做了调整其次就是之前那个只能查看实时天气这个天气预报我还加入了未来天气
先看一下对比图
技术分享

因为这是给我杨凌一个闺蜜写的逗她开心也练练技术所以中间那部分是自己定义的一些话当然可以替换成穿衣建议什么的

不管之前那个天气预报这个重新来一遍
在你刚刚创建好这个项目的时候因为需要联网操作所以我们需要先导入网络包和在manifests文件中进行网络权限的申请
1 导入网络包


dependencies {
    compile fileTree(dir: ‘libs‘, include: [‘*.jar‘])
    testCompile ‘junit:junit:4.12‘
    compile ‘com.android.support:appcompat-v7:23.2.1‘
    compile files(‘libs/httpclient-4.4.1.jar‘)
    compile files(‘libs/httpcore-4.4.1.jar‘)
}

那个http的两个就是这次需要的网络包
要注意的是在加入网络包的同时我们还需要在上面加上这样一段代码

packagingOptions {//导入http包的时候必须要加的以下这段话
    exclude ‘META-INF/DEPENDENCIES.txt‘
    exclude ‘META-INF/LICENSE.txt‘
    exclude ‘META-INF/NOTICE.txt‘
    exclude ‘META-INF/NOTICE‘
    exclude ‘META-INF/LICENSE‘
    exclude ‘META-INF/DEPENDENCIES‘
    exclude ‘META-INF/notice.txt‘
    exclude ‘META-INF/license.txt‘
    exclude ‘META-INF/dependencies.txt‘
    exclude ‘META-INF/LGPL2.1‘
}

Manifests文件中是这样的
在application之外加上

<uses-permission android:name="android.permission.INTERNET"></uses-permission>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

基本准备工作就完成了这样在编码的工程中会减少很多错误

现在就开始要入手这个项目的第一个关键的部分就是layout
我的布局写的很烂基本都是最简单的控件组成的显示大部分用的TextView
先把代码贴上来因为id这个在后面有些不知道的还要查这个代码

<?xml version="1.0" encoding="utf-8"?>

*如果想直接用源码以上 over ，如果想知道怎么实现的
以下*
代码不是很长其中还有一些log 和system 都是我在调试过程中留下的太懒不想删掉了就留下了

来慢慢分解一下
我看程序喜欢从oncreat()开始
所以我们来一起看一下oncreat里面怎么走的然后再看用到了什么方法是什么功能

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Init();//初始化控件
        if(!isNetworkConnected())//检查手机是否有网络
        {


            Toast toast = Toast.makeText(getApplicationContext(), "宝宝你手机没有网", Toast.LENGTH_LONG);//显示时间较长
            toast.setGravity(Gravity.CENTER, 0, 0);// 居中显示
            toast.show();


        }
        swipeRefreshLayout.setColorSchemeResources(android.R.color.holo_blue_light, android.R.color.holo_red_light, android.R.color.holo_orange_light, android.R.color.holo_green_light);
        swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {

                                @Override
                        public void onRefresh() {
                                    Weather_Thread weather_thread =new Weather_Thread();
                                    Weather_now_Thread weather_now_thread = new Weather_now_Thread();
                                    new Thread(weather_thread).start();
                                    new Thread(weather_now_thread).start();
                                    handler = new Myhandler();
                                    handler_now = new Myhandler_now();
                                    swipeRefreshLayout.setRefreshing(false);
                                    // TODO Auto-generated method stub
                                    new Handler().postDelayed(new Runnable() {

                                        @Override
                                        public void run() {
                                            // TODO Auto-generated method stub
                                            swipeRefreshLayout.setRefreshing(false);
                                        }
                                    }, 10000);
                            }
                    });


//以上都是下拉刷新的不需要可以不要这段

        Weather_Thread weather_thread =new Weather_Thread();
        Weather_now_Thread weather_now_thread = new Weather_now_Thread();
        new Thread(weather_thread).start();
        new Thread(weather_now_thread).start();
        handler = new Myhandler();
        handler_now = new Myhandler_now();
        //以上是两个线程的开启 一个是实时天气一个是未来天气 
      //  一开始就可以查询数据显示 
      //下面这个是点击切换城市然后的点击事件 线程的那些和一开始一样只不过又更新了一次 

        change.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Weather_Thread weather_thread =new Weather_Thread();
                Weather_now_Thread weather_now_thread = new Weather_now_Thread();
                new Thread(weather_thread).start();
                new Thread(weather_now_thread).start();
                handler = new Myhandler();
                handler_now = new Myhandler_now();
            }
        });

//完啦是不是很简单  其实主要的结构就是这样

初始化线程绑定 over！！
可是线程里面的操作是怎么样的呢

下来看一下线程里面的我们直接看未来天气因为里面解析了json数组所以来看一下代码

public class Weather_Thread implements  Runnable{
    public void run(){
        String first = "http://api.k780.com:88/?app=weather.future&weaid=";
        String city = search_city.getText().toString().trim();
        String last="&&appkey=18276&sign=3f3716462bb4ed68bd082761c3602509&format=json";
        String  Weather=getURLConnection(first+city+last);
        //注意上面这个是调用了一个网络访问返回一个String的方法 这个方法也是自己写的 作用就是 把接口传进去 返回这个接口得到的字符串

        Message msg1 = new Message();
        Bundle bundle1 = new Bundle();
        bundle1.putString("Weather", Weather);
        msg1.setData(bundle1);
        handler.sendMessage(msg1);
        //放在异步处理机制的handle里面可以把线程的消息信息什么的传递到主线程 因为我们得到消息之后是要改变UI的所以不能再在子线程中改变必须传递到主线程中这个传递过去的就是那个字符串 因为网络请求是一个耗时的操作 要放在线程中
     }
    }

传递到主线程里面之后剩下的就是json解析的部分了重点

 public class Myhandler extends Handler{
        public void handleMessage(Message msg){
            String Weather = msg.getData().getString("Weather");
            System.out.println("septa"+Weather);
            if(!Weather.equals("")){
                try {
                    JSONArray jsonObjs = new JSONObject(Weather).getJSONArray("result");
                   // int jsona = new JSONObject(Weather).getInt         ("success");
                   // System.out.println("septqqq"+jsona);
                        for (int i = 0; i < jsonObjs.length(); i++) {
                            JSONObject jsonOb0 = (JSONObject) jsonObjs.get(i);
                            if (i == 0) {
                                day_one.setText(jsonOb0.getString("week"));
                                image_one.setText(jsonOb0.getString("weather"));
                                high_one.setText(jsonOb0.getString("temp_high") + "°");
                                low_one.setText(jsonOb0.getString("temp_low") + "°");

                            }


                            if (i == 1) {
                                day_two.setText(jsonOb0.getString("week"));
                                image_two.setText(jsonOb0.getString("weather"));
                                high_two.setText(jsonOb0.getString("temp_high") + "°");
                                low_two.setText(jsonOb0.getString("temp_low") + "°");

                            }
                            if (i == 2) {
                                day_three.setText(jsonOb0.getString("week"));
                                image_three.setText(jsonOb0.getString("weather"));
                                high_three.setText(jsonOb0.getString("temp_high") + "°");
                                low_three.setText(jsonOb0.getString("temp_low") + "°");


                            }
                            if (i == 3) {
                                day_four.setText(jsonOb0.getString("week"));
                                image_four.setText(jsonOb0.getString("weather"));
                                high_four.setText(jsonOb0.getString("temp_high") + "°");
                                low_four.setText(jsonOb0.getString("temp_low") + "°");

                            }
                            if (i == 4) {
                                day_five.setText(jsonOb0.getString("week"));
                                image_five.setText(jsonOb0.getString("weather"));
                                high_five.setText(jsonOb0.getString("temp_high") + "°");
                                low_five.setText(jsonOb0.getString("temp_low") + "°");

                            }
                            if (i == 5) {
                                day_six.setText(jsonOb0.getString("week"));
                                image_six.setText(jsonOb0.getString("weather"));
                                high_six.setText(jsonOb0.getString("temp_high") + "°");
                                low_six.setText(jsonOb0.getString("temp_low") + "°");

                            }
                            if (i == 6) {
                                day_seven.setText(jsonOb0.getString("week"));
                                image_seven.setText(jsonOb0.getString("weather"));
                                high_seven.setText(jsonOb0.getString("temp_high") + "°");
                                low_seven.setText(jsonOb0.getString("temp_low") + "°");

                            }

                        }
                }catch (Exception e) {
                    e.printStackTrace();
                }


            }

        }
    }

json解析这部分我刚开始学所以估计说的也不很精准
就是通过他的键得到他的值这样的一个过程
然后根据json数组的长度用循环把数组的内容一个个取出来显示
就得到了未来天气

实时天气那部分和未来天气在线程这里的操作是一样的只是再解析的时候比解析数组要简单一些代码都在上面可以仔细看看
最后给出我用的接口
未来天气：
http://api.k780.com:88/?app=weather.future&weaid=1&&appkey=10003&sign=b59bc3ef6191eb9f747dd4e83c99f2a4&format=json
实时天气
http://api.k780.com:88/?app=weather.today&weaid=1&&appkey=10003&sign=b59bc3ef6191eb9f747dd4e83c99f2a4&format=json

差不多就这样了现在这个天气预报就完成了
下来准备把四大组件好好看一下基础
再重复一下四大组件
一、Activity
二、Service
三、Broadcast Receiver
四、Content Provider
学了肯定再来贴啊啊啊啊啊啊啊啊啊啊啊学习好难
可是难了才有成就感加油啊么么哒
肯定会越来越好的
