    最近无聊，写了一个天气挂件，再不写代码，就快荒废了~~~    不多说了，上源码：https://github.com/WanShenHere/WeatherWidget.git    ![效果图](http://img.blog.csdn.net/20160331104747809)    首先，考虑天气数据的来源。在网上找了半天，最后还是用的聚合数据的天气数据。![聚合数据API](http://img.blog.csdn.net/20160331100604230)     这是自己写的申请数据接口：

    public class HttpApi {    private static HttpUtils httpUtils = new HttpUtils();    public static void getJsonData(String cityName,            final OnHttpRequestCallBack<StatusBean> callBack) {        String url = Constant.URL;        url = url + "?cityname=" + cityName + "&key=" + Constant.APIKEY;        httpUtils.send(HttpMethod.GET, url, new RequestCallBack<String>() {            @Override            public void onFailure(HttpException arg0, String arg1) {                Log.e("API", "下载失败");            }            @Override            public void onSuccess(ResponseInfo<String> responseInfo) {                String result = responseInfo.result;                StatusBean statusBean = null;                try {                    statusBean = new Gson().fromJson(result, StatusBean.class);                    callBack.onSuccess(statusBean);                } catch (Exception e) {                    // TODO: handle exception                }            }        });    }}

这里是用的xutils 工具申请数据，使用了gson把数据解析成了StatusBean对象，方便使用。由于聚合数据提供的字符串数据较复杂，所以对应数据建立了比较多的Bean。我茫茫多的Bean

 得到了天气数据，现在还缺的就是定位了。这里使用的是百度定位api，具体流程网上都有，按百度api文档来写就可以了。 下面是写布局文件：

    <?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="wrap_content" >    <TextView        android:id="@+id/tv_time"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_alignParentLeft="true"        android:layout_alignParentTop="true"        android:text="11:24"        android:textSize="45sp" />    <TextView        android:id="@+id/tv_day"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_below="@id/tv_time"        android:text="3/17"        android:textSize="12sp" />    <TextView        android:id="@+id/tv_week"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_below="@id/tv_time"        android:layout_marginLeft="5dp"        android:layout_toRightOf="@id/tv_day"        android:text="周四"        android:textSize="12sp" />    <TextView        android:id="@+id/tv_city"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_alignRight="@id/tv_time"        android:layout_below="@id/tv_time"        android:text="深圳市"        android:textSize="12sp" />    <TextView        android:id="@+id/v_h"        android:layout_width="1dp"        android:layout_height="40dp"        android:layout_marginLeft="10dp"        android:layout_marginRight="10dp"        android:layout_marginTop="15dp"        android:layout_toRightOf="@id/tv_time"        android:background="#555" />    <ImageView        android:id="@+id/iv_pic"        android:layout_width="46dp"        android:layout_height="46dp"        android:layout_toRightOf="@id/v_h"        android:src="@drawable/ic_launcher" />    <TextView        android:id="@+id/tv_weather"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_alignBottom="@id/tv_city"        android:layout_alignLeft="@id/iv_pic"        android:text="阵雨 17°"        android:textSize="12sp" /></RelativeLayout>

    再就是按写widget的流程，要有WeatherService

public class WeatherService extends Service {    Timer timer;    StatusBean statusBean;    String cityname = null;    public LocationClient mLocationClient = null;    public BDLocationListener myListener = new MyLocationListener();    private SimpleDateFormat sdf = new SimpleDateFormat("HH:mm");    @Override    public IBinder onBind(Intent arg0) {        return null;    }    @Override    public void onCreate() {        super.onCreate();        mLocationClient = new LocationClient(getApplicationContext()); // 声明LocationClient类        mLocationClient.registerLocationListener(myListener);        initLocation();        mLocationClient.start();        timer = new Timer();        timer.schedule(new TimerTask() {            @Override            public void run() {                updateTime();            }        }, 0, 1000);    }    @Override    public void onDestroy() {        super.onDestroy();    }    private void updateTime() {        String time = sdf.format(new Date());        RemoteViews rv = new RemoteViews(getPackageName(), R.layout.widget);        rv.setTextViewText(R.id.tv_time, time);        AppWidgetManager manager = AppWidgetManager                .getInstance(getApplicationContext());        ComponentName cn = new ComponentName(getApplicationContext(),                WidgetProvider.class);        manager.updateAppWidget(cn, rv);    }    public class MyLocationListener implements BDLocationListener {        @Override        public void onReceiveLocation(BDLocation bdLocation) {            String cityname = bdLocation.getCity();            if (cityname == null) {                Log.e("cityname", "定位失败");                return;            }            initData(cityname);        }    }    private void initData(String cityname) {        HttpApi.getJsonData(cityname, new OnHttpRequestCallBack<StatusBean>() {            @Override            public void onSuccess(StatusBean result) {                statusBean = result;                Log.e("statusBean", statusBean.toString());                if (statusBean != null) {                    RealtimeBean realtime = statusBean.getResult().getData()                            .getRealtime();                    RemoteViews rv = new RemoteViews(getPackageName(),                            R.layout.widget);                    String date = realtime.getDate();                    String[] arr = date.split("-");                    String dayString = arr[1] + "/" + arr[2];                    Log.e("dayString", dayString);                    rv.setTextViewText(R.id.tv_day, dayString);                    String weekString = getWeek(realtime.getWeek());                    Log.e("weekString", weekString);                    rv.setTextViewText(R.id.tv_week, weekString);                    String weatherString = realtime.getWeather().getInfo()                            + "  " + realtime.getWeather().getTemperature()                            + "°";                    Log.e("weatherString", weatherString);                    rv.setTextViewText(R.id.tv_weather, weatherString);                    // String imageName = "pic" +                    // realtime.getWeather().getImg();                    int[] picId = { R.drawable.pic00, R.drawable.pic01,                            R.drawable.pic02, R.drawable.pic03,                            R.drawable.pic04, R.drawable.pic05,                            R.drawable.pic06, R.drawable.pic07,                            R.drawable.pic08, R.drawable.pic09,                            R.drawable.pic10, R.drawable.pic11,                            R.drawable.pic12, R.drawable.pic13,                            R.drawable.pic14, R.drawable.pic15,                            R.drawable.pic16, R.drawable.pic17,                            R.drawable.pic18, R.drawable.pic19,                            R.drawable.pic20, R.drawable.pic21,                            R.drawable.pic22, R.drawable.pic23,                            R.drawable.pic24, R.drawable.pic25,                            R.drawable.pic26, R.drawable.pic27,                            R.drawable.pic28, R.drawable.pic29,                            R.drawable.pic30, R.drawable.pic31,                            R.drawable.pic53, R.drawable.undefined };                    int imgInfo = Integer.parseInt(realtime.getWeather()                            .getImg());                    Log.e("imgInfo", "" + imgInfo);                    int imgId = picId[imgInfo];                    if (imgInfo == 53) {                        imgId = picId[picId.length - 2];                    }                    if (imgInfo < 0 || imgInfo > 53) {                        imgId = picId[picId.length - 1];                    }                    rv.setImageViewResource(R.id.iv_pic, imgId);                    AppWidgetManager manager = AppWidgetManager                            .getInstance(getApplicationContext());                    ComponentName cn = new ComponentName(                            getApplicationContext(), WidgetProvider.class);                    manager.updateAppWidget(cn, rv);                }            }            @Override            public void onFailure(HttpException exception, String errorString) {            }        });    }    public int getResource(String imageName) {        Context ctx = getBaseContext();        int resId = getResources().getIdentifier(imageName, "drawable",                ctx.getPackageName());        return resId;    }    private String getWeek(int weekNum) {        String weekString = "";        switch (weekNum) {        case 1:            weekString = "周一";            break;        case 2:            weekString = "周二";            break;        case 3:            weekString = "周三";            break;        case 4:            weekString = "周四";            break;        case 5:            weekString = "周五";            break;        case 6:            weekString = "周六";            break;        case 7:            weekString = "周日";            break;        default:            break;        }        return weekString;    }    private void initLocation() {        LocationClientOption option = new LocationClientOption();        option.setLocationMode(LocationMode.Battery_Saving);// 可选，默认高精度，设置定位模式，高精度，低功耗，仅设备        option.setCoorType("bd09ll");// 可选，默认gcj02，设置返回的定位结果坐标系        int span = 1000 * 3600;        option.setScanSpan(span);// 可选，默认0，即仅定位一次，设置发起定位请求的间隔需要大于等于1000ms才是有效的        option.setIsNeedAddress(true);// 可选，设置是否需要地址信息，默认不需要        option.setOpenGps(true);// 可选，默认false,设置是否使用gps        option.setLocationNotify(false);// 可选，默认false，设置是否当gps有效时按照1S1次频率输出GPS结果        option.setIsNeedLocationDescribe(false);// 可选，默认false，设置是否需要位置语义化结果，可以在BDLocation.getLocationDescribe里得到，结果类似于“在北京天安门附近”        option.setIsNeedLocationPoiList(false);// 可选，默认false，设置是否需要POI结果，可以在BDLocation.getPoiList里得到        option.setIgnoreKillProcess(false);// 可选，默认true，定位SDK内部是一个SERVICE，并放到了独立进程，设置是否在stop的时候杀死这个进程，默认不杀死        option.SetIgnoreCacheException(false);// 可选，默认false，设置是否收集CRASH信息，默认收集        option.setEnableSimulateGps(false);// 可选，默认false，设置是否需要过滤gps仿真结果，默认需要        mLocationClient.setLocOption(option);    }}

和WidgetProvider

public class WidgetProvider extends AppWidgetProvider {    @Override    public void onDeleted(Context context, int[] appWidgetIds) {        // TODO Auto-generated method stub        super.onDeleted(context, appWidgetIds);        // widget被从屏幕移除        context.stopService(new Intent(context, WeatherService.class));    }    @Override    public void onDisabled(Context context) {        // TODO Auto-generated method stub        super.onDisabled(context);        // 最后一个widget被从屏幕移除时执行    }    @Override    public void onEnabled(Context context) {        // TODO Auto-generated method stub        super.onEnabled(context);        // 第一个widget添加到屏幕上执行        context.startService(new Intent(context, WeatherService.class));    }    @Override    public void onUpdate(Context context, AppWidgetManager appWidgetManager,            int[] appWidgetIds) {        // TODO Auto-generated method stub        super.onUpdate(context, appWidgetManager, appWidgetIds);        // 刷新widget        // remoteView 和 AppWidgetManager    }    @Override    public void onReceive(Context context, Intent intent) {        // TODO Auto-generated method stub        super.onReceive(context, intent);    }}

      ok，大功告成。
