功能介绍

实现了点击扫一扫跳转到微信扫一扫，支付宝扫一扫。
点击搜索地名，跳转百度地图，并语言播报
其中专享福利与附近车位分别是横向RecyclerView和竖向滑动RecyclerView
点击附近车位的任意子项可以直接根据子项上的地址直接导航(前提必须安装百度地图)

效果图如下：

首先判断是否声明权限

if (ContextCompat.checkSelfPermission( Function.this, Manifest.permission.ACCESS_FINE_LOCATION ) != PackageManager.PERMISSION_GRANTED) {
            PermissionList.add( Manifest.permission.ACCESS_FINE_LOCATION );
        }
        if (ContextCompat.checkSelfPermission( Function.this, Manifest.permission.READ_PHONE_STATE ) != PackageManager.PERMISSION_GRANTED) {
            PermissionList.add( Manifest.permission.READ_PHONE_STATE );
        }
        if (ContextCompat.checkSelfPermission( Function.this, Manifest.permission.WRITE_EXTERNAL_STORAGE ) != PackageManager.PERMISSION_GRANTED) {
            PermissionList.add( Manifest.permission.WRITE_EXTERNAL_STORAGE );
        }
        if (!PermissionList.isEmpty()) {
            String[] Permissions = PermissionList.toArray( new String[PermissionList.size()] );//转化为数组
            ActivityCompat.requestPermissions( Function.this, Permissions, 1 );//一次性申请权限
        } else {
            /*****************如果权限都已经声明，开始配置参数*****************/
            requestLocation();
        }

百度地图参数配置

 /*******************初始化百度地图各种参数*******************/
    private void initLocation() {

        LocationClientOption option = new LocationClientOption();
        option.setLocationMode(LocationClientOption.LocationMode.Hight_Accuracy);
        /**可选，设置定位模式，默认高精度LocationMode.Hight_Accuracy：高精度；
         * LocationMode. Battery_Saving：低功耗；LocationMode. Device_Sensors：仅使用设备；*/
        option.setCoorType("bd09ll");
        /**可选，设置返回经纬度坐标类型，默认gcj02gcj02：国测局坐标；bd09ll：百度经纬度坐标；bd09：百度墨卡托坐标；
         海外地区定位，无需设置坐标类型，统一返回wgs84类型坐标*/
        option.setScanSpan(3000);
        /**可选，设置发起定位请求的间隔，int类型，单位ms如果设置为0，则代表单次定位，即仅定位一次，默认为0如果设置非0，需设置1000ms以上才有效*/
        option.setOpenGps(true);
        /**可选，设置是否使用gps，默认false使用高精度和仅用设备两种定位模式的，参数必须设置为true*/
        option.setLocationNotify(true);
        /**可选，设置是否当GPS有效时按照1S/1次频率输出GPS结果，默认false*/
        option.setIgnoreKillProcess(false);
        /**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（建议）不杀死，即setIgnoreKillProcess(true)*/
        option.SetIgnoreCacheException(false);
        /**可选，设置是否收集Crash信息，默认收集，即参数为false*/
        option.setIsNeedAltitude(true);/**设置海拔高度*/
        option.setWifiCacheTimeOut(5 * 60 * 1000);
        /**可选，7.2版本新增能力如果设置了该接口，首次启动定位时，会先判断当前WiFi是否超出有效期，若超出有效期，会先重新扫描WiFi，然后定位*/
        option.setEnableSimulateGps(false);
        /**可选，设置是否需要过滤GPS仿真结果，默认需要，即参数为false*/
        option.setIsNeedAddress(true);
        /**可选，设置是否需要地址信息，默认不需要*/
        client.setLocOption(option);
        /**mLocationClient为第二步初始化过的LocationClient对象需将配置好的LocationClientOption对象，通过setLocOption方法传递给LocationClient对象使用*/
    }

判断是否安装了百度地图，然后进行跳转搜索

/****************判断百度地图是否安装***************/
    public static boolean isBaiduMapInstalled(){
        return isInstallPackage(BAIDUMAPPACKAGE);
    }
    private static boolean isInstallPackage(String packageName) {
        return new File("/data/data/" + packageName).exists();
    }

跳转以及语言播报

 Search.setOnClickListener( new View.OnClickListener() {
         @Override
         public void onClick(View v) {
             //根据搜索栏搜索的地点，然后根据自身的经纬度，进行查询
             String EndAddress = SearchPlace.getText().toString();
             String SpeakContent = "本次导航从当前位置前往"+EndAddress;
             String Zeng = "警告警告检测到周围有曾大屁出现快疏散人群她要放屁了她要放屁了她要放屁了重要的事情说三遍";
             if (TTS != null && !TTS.isSpeaking()) {
                 TTS.setPitch(0.0f);// 设置音调，值越大声音越尖（女生），值越小则变成男声,1.0是常规
                 if (EndAddress.equals( "曾大屁" ))
                 {
                     TTS.speak(Zeng,TextToSpeech.QUEUE_FLUSH, null);
                 }else {
                     TTS.speak( SpeakContent, TextToSpeech.QUEUE_FLUSH, null );
                 }
             }else {
                 Toast.makeText( Function.this, "语音助手错误", Toast.LENGTH_LONG ).show();
             }
             if (isBaiduMapInstalled()) {
                 Navigation(EndAddress);
             } else {
                 // 未安装
                 Toast.makeText( Function.this, "您尚未安装百度地图", Toast.LENGTH_LONG ).show();
             }
         }
     } );
    }

语言播报类初始化

    /****************语音助手监听事件***************/
    class InitTTS implements TextToSpeech.OnInitListener{

        @Override
        public void onInit(int status) {
            if (status == TextToSpeech.SUCCESS) {
                int result = TTS.setLanguage( Locale.CHINA);
                if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED) {
                    Toast.makeText( Function.this, "数据丢失或不支持", Toast.LENGTH_SHORT).show();
                }
            }
        }

    }

接下来介绍跳转到微信扫一扫和支付宝扫一扫
首先判断本地是否安装了两个软件，然后进行跳转

 /****************监测是否安装了微信***************/
    public static boolean CheckWeiXinInstalled(Context context) {
        final PackageManager packageManager = context.getPackageManager();// 获取packagemanager
        List<PackageInfo> pinfo = packageManager.getInstalledPackages( 0 );// 获取所有已安装程序的包信息
        if (pinfo != null) {
            for (int i = 0; i < pinfo.size(); i++) {
                String pn = pinfo.get( i ).packageName;
                if (pn.equals( "com.tencent.mm" )) {
                    return true;
                }
            }
        }
        return false;
    }
    /****************监测支付宝是否安装***************/
    public static boolean CheckAliPayInstalled(Context context) {
        Uri uri = Uri.parse("alipays://platformapi/startApp");
        Intent intent = new Intent(Intent.ACTION_VIEW, uri);
        ComponentName componentName = intent.resolveActivity(context.getPackageManager());
        return componentName != null;
    }

/****************跳转到微信扫一扫***************/
    private void toWeiXinScan(Context context){
        try {
            Intent intent = Function.this.getPackageManager().getLaunchIntentForPackage( "com.tencent.mm" );
            intent.putExtra( "LauncherUI.From.Scaner.Shortcut", true );
            startActivity( intent );

        } catch (Exception e) {
            Toast.makeText( Function.this, "没有安装微信", Toast.LENGTH_SHORT ).show();
        }

    }
    /****************跳转到支付宝扫一扫***************/
    public static void toAliPayScan(Context context)
    {
        try
        {
            Uri uri = Uri.parse("alipayqr://platformapi/startapp?saId=10000007");
            Intent intent = new Intent(Intent.ACTION_VIEW, uri);
            context.startActivity(intent);

        } catch (Exception e)
        {
            Toast.makeText(context, "打开失败，请检查是否安装了支付宝", Toast.LENGTH_SHORT).show();
        }

    }
