百度地图申请KEY，定位和获取周边热点

百度地图申请key一 打包：1.先用android studio 生成 key.store2.点击Build–Generate Signed APK…3.create new…4.输入E:\key.store5.输入密码6.key下的Alias中输入key7.输入key的密码8.Certificate中输入。。随便输入，点OK完成9.返回来，输入密码。key alias中输入刚刚的key10.下一步二 获取SHA1 的值1.打开Android Studio的Tools->Open Terminal…2.定位到key.store 所在的位置3.输入命令：keytool -v -list -keystore key.store4.输入密码/**百度地图定位配置*/1.到官方下载这两个包armeabi/liblocSDK5.solocSDK_5.0.jar 导入lib里面2.AndroidManifest.xml配置文件的<application> 中配置 <service>和 <meta-data> <service android:name="com.baidu.location.f" android:enabled="true" android:process=":remote" > <intent-filter> <action android:name="com.baidu.location.service_v2.2" > </action> </intent-filter> </service><!–配置key–> <meta-data android:name="com.baidu.lbsapi.API_KEY" android:value="VRMNc7QoiSM5ar5at5g3lRQD" /> 3.在build.gradle中的android{}中配置//定位要的配置以下代码 sourceSets { main { res.srcDirs = [‘src/main/res’, ‘src/main/res/values-zhccccc’] assets.srcDirs = [‘src/main/assets’, ‘src/main/assets/2’] jni.srcDirs = [‘src/main/jni’, ‘src/main/jni/’] jniLibs.srcDirs = [‘libs’] } }4.代码中添加定位控件和监听a.定义变量 /**定位控件*/ LocationClient mLocClient; /**定位监听*/ public MyLocationListenner myListener;b.初始化 public void initdingwei(){// 定位初始化myListener = new MyLocationListenner();mLocClient = new LocationClient(this);mLocClient.registerLocationListener(myListener);LocationClientOption option = new LocationClientOption();option.setOpenGps(true);// 打开gpsoption.setCoorType("bd09ll"); // 设置坐标类型option.setScanSpan(2000); // 设置扫描间隔，，单位是毫秒option.setIsNeedAddress(true);// 设置是否需要地址信息，默认为无地址mLocClient.setLocOption(option);mLocClient.start();}c.设置监听器 /*** 定位SDK监听函数*/public class MyLocationListenner implements BDLocationListener {@Overridepublic void onReceiveLocation(BDLocation location) {if (location == null) return;Log.i(TAG, "SDK监听函数11–>" + location.getLatitude() + " " + location.getLongitude() + " " + location.getCity());}public void onReceivePoi(BDLocation poiLocation) {}}d.在需要定位的时候调用initdingwei()方法/**百度地图接口之获取周边热点*/ /*** 查询周边* * ak=您的密钥&* output=json&* query=%E9%93%B6%E8%A1%8C&* page_size=10&* page_num=0&* scope=1&* location=39.915,116.404&* radius=2000*/public void getdata() {HttpUtils http = new HttpUtils();RequestParams params = new RequestParams();try {params.addBodyParameter("query", URLEncoder.encode("银行", "UTF-8"));//params.addBodyParameter("location", URLEncoder.encode("29", "UTF-8")+"."+URLEncoder.encode("531831", "UTF-8")+","+URLEncoder.encode("106", "UTF-8")+"."+URLEncoder.encode("531831", "UTF-8"));//"29.531831,106.576501");params.addBodyParameter("radius", "2000");params.addBodyParameter("output", "json");params.addBodyParameter("ak", "VRMNc7QoiSM5ar5at5g3lRQD");params.addBodyParameter("scope", "1");params.addBodyParameter("page_size", "10");params.addBodyParameter("page_num", "0");params.addBodyParameter("mcode", "DA:4C:B6:A9:55:62:1D:AD:12:29:DD:7B:69:31:67:47:C5:B2:4E:E1;szj.com.ditu");http.send(HttpRequest.HttpMethod.POST,//"?ak=VRMNc7QoiSM5ar5at5g3lRQD&output=json&query=%E9%93%B6%E8%A1%8C&page_size=10&page_num=0&scope=1&location=29.531831,106.576501&radius=2000&mcode==DA:4C:B6:A9:55:62:1D:AD:12:29:DD:7B:69:31:67:47:C5:B2:4E:E1;szj.com.ditu","?ak=VRMNc7QoiSM5ar5at5g3lRQD&output=json&query=" + URLEncoder.encode("餐馆", "UTF-8")+URLEncoder.encode("$", "UTF-8")+URLEncoder.encode("银行", "UTF-8") + "&page_size=20&page_num=0&scope=1&location="+URLEncoder.encode(latitude, "UTF-8")+","+URLEncoder.encode(longitude, "UTF-8")+"&radius=2000&mcode==DA:4C:B6:A9:55:62:1D:AD:12:29:DD:7B:69:31:67:47:C5:B2:4E:E1;szj.com.ditu",params,new RequestCallBack<String>() {@Overridepublic void onStart() {}@Overridepublic void onLoading(long total, long current, boolean isUploading) {}@Overridepublic void onSuccess(ResponseInfo<String> responseInfo) {String Data = responseInfo.result.toString();try {JSONObject jsonObject = new JSONObject(Data.toString());if (jsonObject.getInt("status") == 0 && "ok".equals(jsonObject.getString("message"))) {JSONArray jsonArray = jsonObject.getJSONArray("results");ArrayList<Address> data;Gson gson = new Gson();Type type = new TypeToken<ArrayList<Address>>() {}.getType();data = gson.fromJson(jsonArray.toString(), type);adapter.setData(data);adapter.notifyDataSetChanged();}} catch (Exception e) {}}@Overridepublic void onFailure(HttpException error, String msg) {Toast.makeText(context, "连接服务器失败，请检查网络后重试~", Toast.LENGTH_SHORT).show();}});} catch (Exception e) {}}
