因為年前的工作中用到了百度地圖的定位 導航功能，然后又去翻閱了百度sdk相關的api后進行開發，現在對其進行一些整理，方便后面遇到相關開發時使用。
開發之前，先進行準備工作，在百度地圖的開發者網站上下載相關的sdk，導入AS中的libs文件中，然后創建jniLibs的文件夾，將其相關的文件復制進去后，引用即可，然后申請百度地圖相關的key秘鑰，導入相關的權限，根據百度官方的流程進行即可。
首先先在xml文件中引入百度的圖view
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_main" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.example.l.mapdemo.MainActivity"> <com.baidu.mapapi.map.MapView android:id="@+id/mv" android:layout_width="fill_parent" android:layout_height="fill_parent" android:clickable="true" /></RelativeLayout>其進行開發之前 必須先初始化sdk的個組件，如果是多次引用的話，也可以將其抽取成base類進行使用//在使用SDK各組件之前初始化context信息，傳入applicationContext //注意該方法要再setContentView方法之前實現 SDKInitializer.initialize(getApplicationContext()); setContentView(R.layout.activity_main);將百度地圖生命周期與activity的進行綁定
@Override PRotected void onDestroy() { super.onDestroy(); mMapView.onDestroy(); } @Override protected void onResume() { super.onResume(); mMapView.onResume(); } @Override protected void onPause() { super.onPause(); mMapView.onPause(); } @Override protected void onStart() { super.onStart(); mBaiduMap.setMyLocationEnabled(true); if (!mLocationClient.isStarted()) { mLocationClient.start(); } } @Override protected void onStop() { super.onStop(); mLocationClient.stop(); }首先進行定位的開發
定位相關的公共類
//定位相關 private LocationClient mLocationClient = null; private boolean isFristLocation = true;根據百度sdk提供的官方文檔可以看到 其定位相關的類如下private void initLocation() { mLocationClient = new LocationClient(getApplicationContext()); //聲明LocationClient類 initLocationOps(); //注冊監聽函數 mLocationClient.registerLocationListener(new BDLocationListener() { @Override public void onReceiveLocation(BDLocation location) { //mapview 銷毀后不再處理新的接收位置 if (location == null || mMapView == null) return; //構造定位數據 MyLocationData locData = new MyLocationData.Builder() .accuracy(location.getRadius()) //此處設置開發者獲取到的方向信息 .latitude(location.getLatitude()) .longitude(location.getLongitude()).build(); //設置定位數據 mBaiduMap.setMyLocationData(locData); //第一次定位時，將地圖位置移動到當前位置 LatLng ll = new LatLng(location.getLatitude(), location.getLongitude()); mLastLocationData = ll; if (isFristLocation) { isFristLocation = false; MapStatusUpdate u = MapStatusUpdateFactory.newLatLng(ll); mBaiduMap.animateMapStatus(u); } } }); }private void initLocationOps() { LocationClientOption option = new LocationClientOption(); option.setLocationMode(LocationClientOption.LocationMode.Hight_Accuracy );//可選，默認高精度，設置定位模式，高精度，低功耗，僅設備 option.setCoorType("bd09ll");//可選，默認gcj02，設置返回的定位結果坐標系 int span = 1000; option.setScanSpan(span);//可選，默認0，即僅定位一次，設置發起定位請求的間隔需要大于等于1000ms才是有效的 option.setIsNeedAddress(true);//可選，設置是否需要地址信息，默認不需要 option.setOpenGps(true);//可選，默認false,設置是否使用gps option.setLocationNotify(true);//可選，默認false，設置是否當GPS有效時按照1S/1次頻率輸出GPS結果 option.setIsNeedLocationDescribe(true);//可選，默認false，設置是否需要位置語義化結果，可以在BDLocation.getLocationDescribe里得到，結果類似于“在北京天安門附近” option.setIsNeedLocationPoiList(true);//可選，默認false，設置是否需要POI結果，可以在BDLocation.getPoiList里得到 option.setIgnoreKillProcess(false);//可選，默認true，定位SDK內部是一個SERVICE，并放到了獨立進程，設置是否在stop的時候殺死這個進程，默認不殺死 option.SetIgnoreCacheException(false);//可選，默認false，設置是否收集CRASH信息，默認收集 option.setEnableSimulateGps(false);//可選，默認false，設置是否需要過濾GPS仿真結果，默認需要 mLocationClient.setLocOption(option); }定位相關基本完成。導航相關代碼:在百度提供的官方demo中找到BNDemoGuideActivity類，這是導航相關的類，將其復制進自己的工程，改掉一些報紅的類即可
