简述
此天气数据源采用心知天气API(试用版)，免费版获取数据有限，简单只能获取普通的简单温度、湿度等，简单例如压力、简单云量、简单可见度等均获取不到，简单试用版相当于正式版，简单可以获取大部分数据，简单试用日期是简单14天。
首页不同城市天气页面之间的简单滑动采用的是ViewPager，编辑界面的简单搜索栏采用的是SearchView+ListView,其中城市数据源是统计到一个xml文件中；通过点击搜索匹配项，插入至SQLite数据库中，简单然后刷新当前天气子项，简单然后通过EventBus通知首页更新views页面。简单处于编辑状态时，删除子项，同样使用EventBus通知首页更新；更新主要是页面数量更新和下方指示器更新。

包括实况天气、逐24小时天气预、未来七天天气预报三部分数据
效果图
获取JSON数据
首先通过OKHttp使用get方式获取数据，不同的天气数据，传入不同的url，所以把请求作为公共方式，然后通过写一个回调接口，将数据源回调至外部。
public void Post(String url, HttpCallback callback){ OkHttpClient client = new OkHttpClient(); final Request request = new Request.Builder() .url(url) .get() .build(); client.newCall(request).enqueue(new Callback() { @Override public void onFailure(Call call, IOException e) { callback.onFailed(ErrorCodeParam.NetworkError); } @Override public void onResponse(Call call, Response response) throws IOException { int code = response.code(); if (code == 200){ String json = response.body().string(); callback.onResponse(json.toString()); }else { callback.onFailed(ErrorCodeParam.PostError); } } }); }URL请求
实况天气URL
具体方法参考官网
官网所展示的请求参数并不是需要所有都添加，例如语言都有默认想，一般不需要提交，在官网也有标注，此处传入key(心知天气API密钥)和城市(你所想获取天气预报的城市，可以是汉字)
/** * 获取当前实况天气*/ public String getNowUrl(String location) { HttpUrl.Builder builder = HttpUrl.parse(WeatherParam.NowWeatherURL).newBuilder(); builder.addQueryParameter("key",WeatherParam.weatherToken); builder.addQueryParameter("location",location); return builder.build().toString(); }逐24小时天气预报URL
具体参考官网
前两项参数与实况天气一致，第三个参数是你需要获取多少小时的天气预报数据，以当前时间为第一个小时；例如：你传入5个小时，你当时系统时间是9点，那么返回的第一个数据就是9点，第二个为10…第5个为13点；以此类推
/** * 获取24小时天气情况*/ public String getHourly24Url(String location,int hours) { HttpUrl.Builder builder = HttpUrl.parse(WeatherParam.Hourly24WeatherURL).newBuilder(); builder.addQueryParameter("key",WeatherParam.weatherToken); builder.addQueryParameter("location",location); builder.addQueryParameter("hours",hours+""); return builder.build().toString(); }未来七天天气预报URL
具体参考官网
第三个参数与逐小时天气预报的小时一致，以当前日期为第一天；请求天数好像最大为15天
/** * 获取未来七天天气预报情况*/ public String getFuture7Url(String location,int days) { HttpUrl.Builder builder = HttpUrl.parse(WeatherParam.Future7WeatherURL).newBuilder(); builder.addQueryParameter("key",WeatherParam.weatherToken); builder.addQueryParameter("location",location); builder.addQueryParameter("days",days+""); return builder.build().toString(); }解析JSON数据
解析实况天气数据
JSON数据格式在上文有提及，返回的数据较多，我们只需要关于天气的即可，地点可以不解析；此处将数据源解析成具体实体类，依旧通过回调接口，暴露给外部。
/** * 获取当前天气情况 */ fun getNowWeather(location: String,callback: WeatherCallback_now) { val url = HttpUtils.getInstance().getNowUrl(location) Log.d(TAG, "url = $url") HttpUtils.getInstance().Post(url, object : HttpCallback { override fun onFailed(ErrorCode: Int) { callback.onFailed(ErrorCode) } override fun onResponse(JSONData: String) { if (TextUtils.isEmpty(JSONData)) { callback.onFailed(0) return } Log.d(TAG, "now = $JSONData") try { val jsonObject = JSONObject(JSONData) val jsonArray = jsonObject.getJSONArray("results") val now = jsonArray.getJSONObject(0).getJSONObject("now") val time : String = jsonArray.getJSONObject(0).getString("last_update"); val bean : WRealTimeBean? = HttpUtils.getInstance().fromJson( now.toString(), WRealTimeBean::class.java ) if (bean != null) { bean.last_update = time bean.location = location; } callback.onSuccess(bean) } catch (e: JSONException) { e.printStackTrace() } } }) }解析逐小时天气预报
步骤与实况天气雷同，区别在于逐小时天气预报返回的数组，所以回调接口，返回也是list数据
/** * 获取24小时天气情况 */ fun getHourly24Weather(location: String,callback: WeatherCallback_24H) { val url = HttpUtils.getInstance().getHourly24Url(location, 24) Log.d(TAG, "url = $url") HttpUtils.getInstance().Post(url, object : HttpCallback { override fun onFailed(ErrorCode: Int) { callback.onFailed(ErrorCode) } override fun onResponse(JSONData: String) { if (TextUtils.isEmpty(JSONData)) { callback.onFailed(0) return } Log.d(TAG, "hourlv24 = $JSONData") try { val jsonObject = JSONObject(JSONData) val jsonArray = jsonObject.getJSONArray("results") val hourly24 = jsonArray.getJSONObject(0).getJSONArray("hourly") val bean: MutableList? = HttpUtils.getInstance().fromListJson( hourly24.toString(), WHourly24Bean::class.java ) callback.onSuccess(bean) } catch (e: JSONException) { e.printStackTrace() } } }) } 解析未来七天天气预报
同样返回的是数组数据，完成数据解析并回调；值得注意的是，如果有存在重复的城市名称，返回的数据也是多份，例如请求的城市名称并不精准，本来想请求张家界的天气数据，但是只输入张家二字，系统后台会返回张家界和张家口的数据，所以我们默认取第一个数据源
/** * 获取未来七天天气情况（包括今天） */ fun getFuture7Weather(location: String,callback: WeatherCallback_7D) { val url = HttpUtils.getInstance().getFuture7Url(location, 7) Log.d(TAG, "url = $url") HttpUtils.getInstance().Post(url, object : HttpCallback { override fun onFailed(ErrorCode: Int) { callback.onFailed(ErrorCode) } override fun onResponse(JSONData: String) { if (TextUtils.isEmpty(JSONData)) { callback.onFailed(0) return } Log.d(TAG, "future7 = $JSONData") try { val jsonObject = JSONObject(JSONData) val jsonArray = jsonObject.getJSONArray("results") val future7 = jsonArray.getJSONObject(0).getJSONArray("daily") val bean: MutableList? = HttpUtils.getInstance().fromListJson( future7.toString(), WFuture7Bean::class.java ) callback.onSuccess(bean) } catch (e: JSONException) { e.printStackTrace() } } }) } 初始化天气详情页
获取当前位置
为了减轻app负重，并未采用高德、百度等API进行位置定位，采用原始的定位方式，使用网络方式进行定位
获取经纬度
获取位置信息需要动态申请位置权限
public String getLocationInfo() { if (ActivityCompat.checkSelfPermission(BaseApplication.context,Group_Location[0]) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(BaseApplication.context, Group_Location[1]) != PackageManager.PERMISSION_GRANTED) { Log.d(TAG, "Don't apply for these permission"); return null; } String strLocation = null; try { //获取系统的服务， locationManager = (LocationManager) BaseApplication.context.getSystemService(Context.LOCATION_SERVICE); //创建一个criteria对象 Criteria criteria = new Criteria(); criteria.setAccuracy(Criteria.ACCURACY_COARSE); //设置不需要获取海拔方向数据 criteria.setAltitudeRequired(false); criteria.setBearingRequired(false); //设置允许产生资费 criteria.setCostAllowed(true); //要求低耗电 criteria.setPowerRequirement(Criteria.POWER_LOW); String provider = locationManager.getBestProvider(criteria, true); Location location = locationManager.getLastKnownLocation(provider); if (location == null)return null; //strLocation = location.getLongitude()+","+location.getLatitude(); strLocation = convertAddress(BaseApplication.context, location.getLatitude(), location.getLongitude()); Log.d(TAG, "location is = " + strLocation); } catch (Exception e) { e.printStackTrace(); } return strLocation; }经纬度转为地理信息
将经纬度转为具体地理信息，由于心知天气API需要提供城市级城市数据，所以我们只需要xx市数据即可
private String convertAddress(Context context, double latitude, double longitude) { Geocoder mGeocoder = new Geocoder(context, Locale.getDefault()); try { List mAddresses = mGeocoder.getFromLocation(latitude, longitude, 1); if (mAddresses != null && mAddresses.size() >0) { Address address = mAddresses.get(0); Log.d(TAG, "国家 is " + address.getCountryName()); Log.d(TAG, "省 is " + address.getAdminArea()); Log.d(TAG, "市 is " + address.getLocality()); Log.d(TAG, "区/县 is " + address.getSubLocality()); Log.d(TAG, "具体 is " + address.getFeatureName()); return address.getLocality(); } } catch (Exception e) { e.printStackTrace(); } return null; }页面初始化
详情页采用的是viewPager添加多个views实现页面滑动；
首先获取数据库内所有存储的城市名称，然后通过get模式获取天气的网络数据，然后填充到adapter中；需要注意的是获取的本地位置在整个app都较为特殊，与其他添加的城市数据存在差距，因为需要改变其显示状态，具体后文会提交，所以并未将此添加到数据库中。
private void initViewPager(){ dao = new Dao(this); locationList = dao.QueryAll(); location = LocationUtils.getInstance().getLocationInfo(); if (locationList == null || locationList.size() == 0){ locationList = new ArrayList<>(); locationList.add(location); }else { locationList.add(0,location); } for (int i = 0; i < locationList.size(); i++) { Message message = new Message(); message.what = WEATHER_Start; message.obj = locationList.get(i); handler.sendMessage(message); } adapter.notifyDataSetChanged(); }单个页面初始化，通过遍历，将所有页面进行填充；每个界面背景图片会根据心知天气返回天气状态发生变化，由于素材有限，只适配了较为常见的几种状态，例如：晴、多云、阴、雨、雪、雷
/** * viewPager页面添加，包括实况天气数据、预期24小时、预报7天*/ private void addView(String location){ View view = LayoutInflater.from(this).inflate(R.layout.activity_main,null,false); LinearLayout weatherLayout; TextView weatherLocation,weatherTemp,weatherStatus,weatherWindDirection,weatherWindSpeed,weatherCloud,weatherFellLikes,weatherHum,weatherVisibility,weatherPressure; RecyclerView weather7D,weather24H; weatherLayout = view.findViewById(R.id.mainLinearLayout); weatherLocation = view.findViewById(R.id.normal_city); weatherTemp = view.findViewById(R.id.normal_temp); weatherStatus = view.findViewById(R.id.normal_status); weatherWindDirection = view.findViewById(R.id.windDirection); weatherWindSpeed = view.findViewById(R.id.windSpeed); weatherCloud = view.findViewById(R.id.cloud); weatherFellLikes = view.findViewById(R.id.bodyTmp); weatherHum = view.findViewById(R.id.hum); weatherVisibility = view.findViewById(R.id.visibility); weatherPressure = view.findViewById(R.id.pressure); weather7D = view.findViewById(R.id.Recycler_7D); weather24H = view.findViewById(R.id.Recycler_24H); ListhourlyBeanList = new ArrayList<>(); ListdailyBeanList = new ArrayList<>(); weather24H.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false)); Weather24HAdapter adapter24H = new Weather24HAdapter(hourlyBeanList); weather24H.setAdapter(adapter24H); weather7D.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false)); Weather7DAdapter adapter7D = new Weather7DAdapter(dailyBeanList); weather7D.setAdapter(adapter7D); viewList.add(view); titleList.add(location); adapter.notifyDataSetChanged(); weatherLocation.setText(location); JsonUtils.INSTANCE.getNowWeather(location, new WeatherCallback_now() { @Override public void onFailed(int ErrorCode) { } @Override public void onSuccess(WRealTimeBean bean) { if (bean != null){ runOnUiThread(()->{ weatherTemp.setText(bean.getTemperature() + "°");//温度 weatherStatus.setText(bean.getText());//天气状态 weatherWindSpeed.setText(bean.getWindSpeed() + "km/h");//风速 weatherWindDirection.setText(bean.getWindDirection()+bean.getWindDirectionDegree()+ "°");//风向 weatherCloud.setText(bean.getClouds() + "%");//云量 weatherFellLikes.setText(bean.getFeelsLike() + "°");//体感温度 weatherHum.setText(bean.getHumidity() + "%");//湿度 weatherVisibility.setText(bean.getVisibility() + "km");//可见度 weatherPressure.setText(bean.getPressure() + "mb");//气压 switch (bean.getText()){ case "晴":weatherLayout.setBackground(getDrawable(R.drawable.icon_bg_sunny));break; case "多云":weatherLayout.setBackground(getDrawable(R.drawable.icon_bg_cloudy));break; case "阴":weatherLayout.setBackground(getDrawable(R.drawable.icon_bg_cloudy));break; case "雨":weatherLayout.setBackground(getDrawable(R.drawable.icon_bg_big_rain));break; case "雪":weatherLayout.setBackground(getDrawable(R.drawable.icon_bg_snow));break; case "雷":weatherLayout.setBackground(getDrawable(R.drawable.icon_bg_thunder));break; } }); }else { Log.d(TAG,"bean is empty"); } } }); JsonUtils.INSTANCE.getFuture7Weather(location, new WeatherCallback_7D() { @Override public void onFailed(int ErrorCode) { } @Override public void onSuccess(ListbeanList) { if (beanList != null && beanList.size() >0){ if (dailyBeanList != null && dailyBeanList.size() >0){ dailyBeanList.clear(); } dailyBeanList.addAll(beanList); runOnUiThread(()->{ adapter7D.notifyDataSetChanged(); }); } } }); JsonUtils.INSTANCE.getHourly24Weather(location, new WeatherCallback_24H() { @Override public void onFailed(int ErrorCode) { } @Override public void onSuccess(ListbeanList) { if (beanList != null && beanList.size() >0){ if (hourlyBeanList != null && hourlyBeanList.size() >0){ hourlyBeanList.clear(); } hourlyBeanList.addAll(beanList); runOnUiThread(()->{ adapter24H.notifyDataSetChanged(); }); } } }); } ViewPager子页面编辑
view添加和删除都是通过EventBus进行监听，然后操作adapter完成操作
/** * 在城市页面进行数据添加或删除，使用EventBus进行监测*/ @Subscribe(threadMode = ThreadMode.MAIN,sticky = true) public void onEvent(LocationBusBean bean){ if (bean != null){ if (bean.getDeletePos() == -1){ addView(bean.getLocation()); updateIndicator(); }else { removeView(bean.getLocation()); } } }页面添加
此功能就是重复调用单个views初始化方法，然后使用adapter进行notify和更新指示器即可
页面删除
通过从天气编辑页面点击的城市子项，传过来的城市数据，然后与views存在的数据进行匹配，然后删除对应的界面
/** * 删除viewPager子项*/ private void removeView(String location){ int position = titleList.indexOf(location); if (position != -1){ viewList.remove(position); titleList.remove(position); adapter.notifyDataSetChanged(); } updateIndicator(); }指示器
指示器是通过两个xml定义不同的圆，然后通过selector文件进行选择，使用一个LinearLayout控件作为指示器控件，通过传入的指示器个数，添加多个view，然后设置背景为selector文件，通过设置其enable属性，改变圆形状态
private void updateIndicator(){ binding.indicatorLayout.removeAllViews(); Listlist = dao.QueryAll(); /** * 因为有一个本地位置，所以需要+1*/ int size = 1; if (list != null){ size = list.size()+1; } for (int i = 0; i < size; i++) { View view = new View(this); view.setBackgroundResource(R.drawable.selector_indicator); view.setEnabled(false); LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(30,30); params.rightMargin = 15; params.leftMargin = 15; binding.indicatorLayout.addView(view,params); } } 天气编辑页
此页面功能包括searchView和listView匹配搜索、城市天津、城市天气简单版子项显示、天气子项编辑等功能
效果图
简版天气数据
此数据与天气详情页数据请求一致，只是数据更为简单，值得注意的是，从天气详情页传过来的城市，并不显示其具体名称，而是以我的位置代替，因为是子线程加载，获取的数据排列方式不一，所以在展示数据时，需要将本地数据一列移到到最前方。
获取数据并初始化
/** * 获取所以数据库中城市的天气*/ private void getWeatherData() { if (dao == null) { dao = new Dao(this); } beanList.clear();//防止数据重复 ListlocationList = dao.QueryAll(); if (locationList == null || locationList.size() == 0) { locationList = new ArrayList<>(); } if (locationList.size() >0) { String data = locationList.get(0); if (!data.equals(location)) { locationList.add(0, location); } }else { locationList.add(location); } for (int i = 0; i < locationList.size(); i++) { postWeather(locationList.get(i), locationList.size()); } } 子项删除
通过EventBus通知天气详情页进行更新
adapter.setDelItemClickListener(new LocationAdapter.OnWeatherItemsClickListener() { @Override public void onClickListener(int pos, String location) { beanList.remove(pos); dao.Delete(location); adapter.notifyDataSetChanged(); EventBus.getDefault().postSticky(new LocationBusBean(location, pos)); } });搜索
效果图
更改SearchView背景和字体样式
定义一个xml文件，然后在SearchView的background属性引用即可改变其背景
android:background="@drawable/searchview_bg"更改SearchView字体颜色，需要获取其内置的一个控件id，然后通过EditText进行改变即可，TextView也可以
/** * 更改searchView字体颜色 */ private void initSearchViewStyle() { EditText editText = (EditText) binding.searchView.findViewById(androidx.appcompat.R.id.search_src_text); if (editText != null) { editText.setTextColor(getColor(R.color.white)); editText.setHintTextColor(getColor(R.color.searchHintColor)); editText.setTextSize(14); SearchManager searchManager = (SearchManager) getSystemService(SEARCH_SERVICE); binding.searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName())); } else { Log.d("MoreLocationActivity", "empty"); } }搜索初始化
重点在于xml城市列表文件，然后采用默认的adapter作为适配

一开始那个提示黑框就比较呆，所以可以通过后面语句进行隐藏，因为搜索列表是覆盖简版天气子项的，所以当搜索列表显示时，天气简版隐藏，反之，亦然；
@Override public boolean onQueryTextSubmit(String query) { return false; } @Override public boolean onQueryTextChange(String newText) { if (TextUtils.isEmpty(newText)) { binding.locationList.clearTextFilter(); binding.locationList.setVisibility(View.GONE); } else { binding.locationList.setVisibility(View.VISIBLE); binding.locationList.setFilterText(newText); //隐藏黑框 binding.locationList.dispatchDisplayHint(View.INVISIBLE); } return true; }下载地址
