根据上次的内容

1. 界面布局

weather_layout.

<??><LinearLayout ="http://schemas.android.com/apk/res/android"  android:layout_width="match_parent"  android:layout_height="match_parent"  android:orientation="vertical" >  <RelativeLayout    android:layout_width="match_parent"    android:layout_height="50dp"    android:background="#484E61" >    <Button      android:id="@+id/switch_city"      android:layout_width="30dp"      android:layout_height="30dp"      android:layout_centerVertical="true"      android:layout_marginLeft="10dp"      android:background="@drawable/home" />    <TextView      android:id="@+id/city_name"      android:layout_width="wrap_content"      android:layout_height="wrap_content"      android:layout_centerInParent="true"      android:textColor="#fff"      android:textSize="24sp" />    <Button      android:id="@+id/refresh_weather"      android:layout_width="30dp"      android:layout_height="30dp"      android:layout_alignParentRight="true"      android:layout_centerVertical="true"    android:layout_marginRight="10dp"    android:background="@drawable/refresh" />  </RelativeLayout>  <RelativeLayout    android:layout_width="match_parent"    android:layout_height="0dp"    android:layout_weight="1"    android:background="#27A5F9">    <TextView      android:id="@+id/publish_text"      android:layout_width="wrap_content"      android:layout_height="wrap_content"      android:layout_alignParentRight="true"      android:layout_marginRight="10dp"      android:layout_marginTop="10dp"      android:textColor="#FFF"      android:textSize="18sp" />    <LinearLayout      android:id="@+id/weather_info_layout"      android:layout_width="wrap_content"      android:layout_height="wrap_content"      android:layout_centerInParent="true"      android:orientation="vertical">      <TextView        android:id="@+id/current_date"        android:layout_width="wrap_content"        android:layout_height="40dp"        android:gravity="center"        android:textColor="#FFF"        android:textSize="18sp"        />      <TextView        android:id="@+id/weather_desp"        android:layout_width="wrap_content"        android:layout_height="60dp"        android:layout_gravity="center_horizontal"        android:gravity="center"        android:textColor="#FFF"        android:textSize="40sp" />      <LinearLayout        android:layout_width="wrap_content"        android:layout_height="60dp"        android:layout_gravity="center_horizontal"        android:orientation="horizontal">        <TextView          android:id="@+id/temp1"          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:layout_gravity="center_vertical"          android:textColor="#FFF"          android:textSize="40sp" />        <TextView          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:layout_gravity="center_vertical"          android:layout_marginLeft="10dp"          android:layout_marginRight="10dp"          android:text="~"          android:textColor="#FFF"          android:textSize="40sp" />        <TextView          android:id="@+id/temp2"          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:layout_gravity="center_vertical"          android:textColor="#FFF"          android:textSize="40sp" />      </LinearLayout>    </LinearLayout>  </RelativeLayout></LinearLayout>

2. 解析服务器返回的数据,存储到本地

Utility.java

import org.json.JSONException;import org.json.JSONObject;import java.text.SimpleDateFormat;import java.util.Date;import java.util.Locale;/** * Created by zps on 2015/9/12. */public class Utility {  public synchronized static boolean handleProvincesResponse(CoolWeatherDB coolWeatherDB, String response) {    //isEmpty用于判断""或null    if (!TextUtils.isEmpty(response)) {      String[] allProvinces = response.split(",");      if (allProvinces != null && allProvinces.length > 0) {        for (String p : allProvinces) {          //split分离,'\\|'传给正则就是"\|",表示对|进行转义,不作为特殊字符使用          String[] array = p.split("\\|");          Province province = new Province();          //数据格式为"代号|城市",故array[0]为代号          province.setProvinceCode(array[0]);          province.setProvinceName(array[1]);          coolWeatherDB.saveProvince(province);        }        return true;      }    }    return false;  }  public static boolean handleCitiesResponse(CoolWeatherDB coolWeatherDB,                        String response, int provinceId) {    if (!TextUtils.isEmpty(response)) {      String[] allCities = response.split(",");      if (allCities != null && allCities.length > 0) {        for (String c : allCities) {          String[] array = c.split("\\|");          City city = new City();          city.setCityCode(array[0]);          city.setCityName(array[1]);          city.setProvinceId(provinceId);          coolWeatherDB.saveCity(city);        }        return true;      }    }    return false;  }  public static boolean handleCountiesResponse(CoolWeatherDB coolWeatherDB,                         String response, int cityId) {    if (!TextUtils.isEmpty(response)) {      String[] allCounties = response.split(",");      if (allCounties != null && allCounties.length > 0) {        for (String c : allCounties) {          String[] array = c.split("\\|");          County county = new County();          county.setCountyCode(array[0]);          county.setCountyName(array[1]);          county.setCityId(cityId);          coolWeatherDB.saveCounty(county);        }        return true;      }    }    return false;  }  public static void handleWeatherResponse(Context context, String response) {    try {      JSONObject jsonObject = new JSONObject(response);      JSONObject weatherInfo = jsonObject.getJSONObject("weatherinfo");      String cityName = weatherInfo.getString("city");      String weatherCode = weatherInfo.getString("cityid");      String temp1 = weatherInfo.getString("temp1");      String temp2 = weatherInfo.getString("temp2");      String weatherDesp = weatherInfo.getString("weather");      String publishTime = weatherInfo.getString("ptime");      saveWeatherInfo(context, cityName, weatherCode, temp1, temp2,          weatherDesp, publishTime);    } catch (JSONException e) {      e.printStackTrace();    }  }  /**   * 将服务器返回的所有天气信息存储到SharedPreferences 文件中。   */  public static void saveWeatherInfo(Context context, String cityName,                    String weatherCode, String temp1, String temp2, String weatherDesp, String                        publishTime) {    SimpleDateFormat sdf = new SimpleDateFormat("yyyy 年M 月d 日",        Locale.CHINA);    Log.d("msg",temp1 );    SharedPreferences.Editor editor = PreferenceManager        .getDefaultSharedPreferences(context).edit();    editor.putBoolean("city_selected", true);    editor.putString("city_name", cityName);    editor.putString("weather_code", weatherCode);    editor.putString("temp1", temp1);    editor.putString("temp2", temp2);    editor.putString("weather_desp", weatherDesp);    editor.putString("publish_time", publishTime);    editor.putString("current_date", sdf.format(new Date()));    editor.commit();  }}

3. 创建一个活动界面(未完)
