基于Android的天气APP

功能

• 第一次打开APP引导页，缓冲加载
• 天气信息的显示
• 广告，推送
• 桌面小工具
• 新闻资讯的查看
• 蓝牙串口传输温度

Json数据分析

天气封装 在目录下新建com.weather.entity

网络请求

  //使用okhttp的封装进行请求
        HttpUtil.sendOkHttpRequest(weatherUrl, new Callback() {
            @Override
            public void onResponse(Call call, Response response) throws IOException {
                //这里有坑
                String responseText = response.body().string();

数据库 数据库只有两个重要的属性，城市名和json数据，目的是在无网络状态下从数据库直接获取json数据，解析后显示到界面上。

桌面小工具

//通过APPWIdgetTarget获取到Image控件
                 mAppWidgetTarget =new AppWidgetTarget(getApplicationContext(),mRemoteViews,R.id.appwiget_picture,mAppwidgetId);
                Glide.with(getApplicationContext()).load(weatherBean.getmNowWeatherBean().getmWeather_Pic()).asBitmap().into(mAppWidgetTarget);

蓝牙和单片机通信模块 单片机上使用的是DS18B20温度传感器，蓝牙是HC-05,通过串口进行温度传输。

界面

  //activity切换的淡入淡出效果
       overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);

//弱引用的使用
 private static class SwitchHandler extends Handler {
        private WeakReference<SplashActivity> mWeakReference;

        SwitchHandler(SplashActivity activity) {
            mWeakReference = new WeakReference<SplashActivity>(activity);
        }

        @Override
        public void handleMessage(Message msg) {
            SplashActivity activity = mWeakReference.get();
            if (activity != null) {
                WeatherActivity.launch(activity);
                activity.finish();
            }
        }
    }
