问题描述

求大师解答？百度地图开发无法定位到我的位置

这是我的代码：

public class MainActivity extends ActionBarActivity {
private MapView mMapView;
private BaiduMap mBaiduMap;

private LocationClient mLocationClient;private MyLocatonListener mLocatonListener;private boolean isFirstIn=true;private Context context;private double mLatitude;private double mLongitude;@Overrideprotected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    requestWindowFeature(Window.FEATURE_NO_TITLE);  //在使用SDK各组件之前初始化context信息，传入ApplicationContext      //注意该方法要再setContentView方法之前实现      SDKInitializer.initialize(getApplicationContext());    setContentView(R.layout.activity_main);    this.context=this;    initView();    initLocation();}private void initLocation() {    // TODO Auto-generated method stub    //mLocationClient=new LocationClient(this);    mLocationClient = new LocationClient(getApplicationContext());     mLocatonListener=new MyLocatonListener();    mLocationClient.registerLocationListener(mLocatonListener);    LocationClientOption option=new LocationClientOption();    option.setCoorType(""bd09ll"");    option.setIsNeedAddress(true);    option.setOpenGps(true);    option.setScanSpan(1000);    mLocationClient.setLocOption(option);}private void initView() {    // TODO Auto-generated method stub    mMapView=(MapView) findViewById(R.id.id_bmapView);    mBaiduMap=mMapView.getMap();    MapStatusUpdate msu=MapStatusUpdateFactory.zoomTo(15.0f);    mBaiduMap.animateMapStatus(msu);}@Overrideprotected void onResume() {    // TODO Auto-generated method stub    super.onResume();    //在activity执行onResume时执行mMapView. onResume ()，实现地图生命周期管理      mMapView.onResume();}@Overrideprotected void onStart() {    // TODO Auto-generated method stub    super.onStart();    mBaiduMap.setMyLocationEnabled(true);    if(mLocationClient.isStarted()){        mLocationClient.start();    }}@Overrideprotected void onPause() {    // TODO Auto-generated method stub    super.onPause();     //在activity执行onPause时执行mMapView. onPause ()，实现地图生命周期管理      mMapView.onPause();  }@Overrideprotected void onStop() {    // TODO Auto-generated method stub    super.onStop();    mBaiduMap.setMyLocationEnabled(false);    mLocationClient.stop();}@Overrideprotected void onDestroy() {    // TODO Auto-generated method stub    super.onDestroy();     //在activity执行onDestroy时执行mMapView.onDestroy()，实现地图生命周期管理      mMapView.onDestroy();  }@Overridepublic boolean onCreateOptionsMenu(Menu menu) {    // Inflate the menu; this adds items to the action bar if it is present.    getMenuInflater().inflate(R.menu.main menu);    return true;}@Overridepublic boolean onOptionsItemSelected(MenuItem item) {    // Handle action bar item clicks here. The action bar will    // automatically handle clicks on the Home/Up button so long    // as you specify a parent activity in AndroidManifest.xml.    switch (item.getItemId()) {    case R.id.id_map_common:        mBaiduMap.setMapType(BaiduMap.MAP_TYPE_NORMAL);        break;    case R.id.id_map_site:        mBaiduMap.setMapType(BaiduMap.MAP_TYPE_SATELLITE);        break;    case R.id.id_map_traffic:        if(mBaiduMap.isTrafficEnabled()){            mBaiduMap.setTrafficEnabled(false);            item.setTitle(""实时交通（off）"");        }        else{            mBaiduMap.setTrafficEnabled(true);            item.setTitle(""实时交通（on）"");        }        break;    case R.id.id_map_location:        centerToMyLocation();        break;    default:        break;    }    return super.onOptionsItemSelected(item);}private void centerToMyLocation() {    LatLng latLng=new LatLng(mLatitude mLongitude);    MapStatusUpdate msu=MapStatusUpdateFactory.newLatLng(latLng);    mBaiduMap.animateMapStatus(msu);}public class MyLocatonListener implements BDLocationListener{    @Override    public void onReceiveLocation(BDLocation location) {        // TODO Auto-generated method stub        MyLocationData data=new MyLocationData.Builder()//        .accuracy(location.getRadius())//        .latitude(location.getLatitude())//        .longitude(location.getLongitude())//        .build();        mBaiduMap.setMyLocationData(data);        mLatitude=location.getLatitude();        mLongitude=location.getLongitude();        if(isFirstIn){            LatLng latLng=new LatLng(location.getLatitude() location.getLongitude());            MapStatusUpdate msu=MapStatusUpdateFactory.newLatLng(latLng);            mBaiduMap.animateMapStatus(msu);            isFirstIn=false;            Toast.makeText(context location.getAddrStr() Toast.LENGTH_SHORT).show();        }    }}
