前两天学习了一下Android的特色--LBS(基于百度地图Android SDK)。有些坑还是得填下,避免以后用到时忘记了。

一 .申请API_KEY

1) :在这里注册并申请。注册之后出现应用列表

2)选择创建应用:下图所示

PS：SHA1找了我好久

按照书上面的，资料上看了，左侧选择项目目录类型project，打开右侧Gradle–>app–>android–>signingReport，发现，诶，怎么没有。。。。（黑人问号脸？？），突然发现左下角有个转换的键（左下标红的地方），一按。。。，答案出来了。

3)完成

创建完成，获得API_KEY。

二 .下载百度定位SDK

下载解压后得到libs文件夹

BaiduLBS_android.jar放在project目录下的app–>libs目录下，其他目录放在app–>main–>新建文件夹比如：jniLibs下

三 .使用百度地图

1） AndroidManifest.xml

添加如下权限

在Application标签中声明SERVICE组件,每个APP拥有自己单独的定位SERVICE

Android定位SDK4.2及之后版本需要在Mainfest.xml正确设置Accesskey（AK），如果设置错误将会导致定位和地理围栏服务无法正常使用。设置AK，在Application标签中加入

            //key:开发者申请的Key

2） 新建activity：LBSwithBaidu，LBSwithBaidu代码如下：

public class LBSwithBaidu extends AppCompatActivity {
         private TextView text;    private LocationClient client;    private  StringBuilder connrentPosition;    private MapView map;    private BaiduMap baidumap;    private boolean ismylocation=true;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        SDKInitializer.initialize(getApplicationContext());        client = new LocationClient(getApplicationContext());        client.registerLocationListener(new MylocationListener());        setContentView(R.layout.activity_lbswith_baidu);        text= (TextView) findViewById(R.id.textView_location);        map= (MapView) findViewById(R.id.mapwithbaidu);        baidumap=map.getMap();        baidumap.setMyLocationEnabled(true);        List
     
       permission = new ArrayList<>();        if (ContextCompat.checkSelfPermission(LBSwithBaidu.this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {            permission.add(Manifest.permission.ACCESS_FINE_LOCATION);        }        if (ContextCompat.checkSelfPermission(LBSwithBaidu.this, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {            permission.add(Manifest.permission.READ_PHONE_STATE);        }        if (ContextCompat.checkSelfPermission(LBSwithBaidu.this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {            permission.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);        }        if (!permission.isEmpty()) {            String[] permissions = permission.toArray(new String[permission.size()]);            ActivityCompat.requestPermissions(LBSwithBaidu.this, permissions, 1);        } else {            requestion();        }    }    private void requestion() {        initlocation();        client.start();    }    private void initlocation() {        LocationClientOption option=new LocationClientOption();        option.setIsNeedAddress(true);        option.setScanSpan(5000);        client.setLocOption(option);    }    @Override    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {        switch (requestCode) {            case 1:                if (grantResults.length > 0) {                    for(int result:grantResults){                        if(result!=PackageManager.PERMISSION_GRANTED){                            Toast.makeText(this, "必须同意权限", Toast.LENGTH_SHORT).show();                            finish();                            return;                        }                    }                    requestion();                }else {                    Toast.makeText(this, "发生错误", Toast.LENGTH_SHORT).show();                }                break;            default:        }    }    public void nagativato(BDLocation bdLocation) {        if (ismylocation) {            LatLng ll = new LatLng(bdLocation.getLatitude(), bdLocation.getLongitude());            Log.d("pipa",bdLocation.getLatitude()+"::"+ bdLocation.getLongitude());            MapStatusUpdate updata = MapStatusUpdateFactory.newLatLng(ll);            baidumap.animateMapStatus(updata);            updata = MapStatusUpdateFactory.zoomTo(16f);            baidumap.animateMapStatus(updata);            ismylocation = false;        }        MyLocationData.Builder loBuilder=new MyLocationData.Builder().latitude(bdLocation.getLatitude())                .longitude(bdLocation.getLongitude());        MyLocationData locationData=loBuilder.build();        baidumap.setMyLocationData(locationData);    }    public class MylocationListener implements BDLocationListener {
             @Override        public void onReceiveLocation(BDLocation bdLocation) {                                             if(bdLocation.getLocType()==BDLocation.TypeGpsLocation||bdLocation.getLocType()==BDLocation.TypeNetWorkLocation){                nagativato(bdLocation);            }            connrentPosition = new StringBuilder();            connrentPosition.append("纬度:").append(bdLocation.getLatitude()).append("\n");            connrentPosition.append("经度:").append(bdLocation.getLongitude()).append("\n");            connrentPosition.append("国家:").append(bdLocation.getCountry()).append("\n");            connrentPosition.append("省:").append(bdLocation.getProvince()).append("\n");            connrentPosition.append("市:").append(bdLocation.getCity()).append("\n");            connrentPosition.append("县:").append(bdLocation.getDistrict()).append("\n");            connrentPosition.append("街道:").append(bdLocation.getStreet()).append("\n");            connrentPosition.append("定位方式:");            if (bdLocation.getLocType() == BDLocation.TypeGpsLocation) {                connrentPosition.append("GPS");            } else if (bdLocation.getLocType() == BDLocation.TypeNetWorkLocation) {                connrentPosition.append("网络定位");            }            runOnUiThread(new Runnable() {                @Override                public void run() {                    text.setText(connrentPosition);                }            });        }        @Override        public void onConnectHotSpotMessage(String s, int i) {        }    }    @Override    protected void onResume() {        super.onResume();        map.onResume();    }    @Override    protected void onPause() {        super.onPause();        map.onPause();    }    @Override    protected void onDestroy() {        super.onDestroy();        client.stop();        map.onDestroy();        baidumap.setMyLocationEnabled(false);    }}
     

效果图：
