百度地图集成

第一步：在百度地图API开放平台下载需要用到的jar包

第二步：添加权限

<!-- 这个权限用于进行网络定位-->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<!-- 这个权限用于访问GPS定位-->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<!-- 用于访问wifi网络信息，wifi信息会用于进行网络定位-->
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<!-- 获取运营商信息，用于支持提供运营商信息相关的接口-->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<!-- 这个权限用于获取wifi的获取权限，wifi信息会用来进行网络定位-->
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/>
<!-- 用于读取手机当前的状态-->
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<!-- 写入扩展存储，向扩展卡写入数据，用于写入离线定位数据-->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<!-- 访问网络，网络定位需要上网-->
<uses-permission android:name="android.permission.INTERNET" />
<!-- SD卡读取权限，用户写入离线定位数据-->
<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/>
第三步：在清单文件的application中添加

<meta-data
    android:name="com.baidu.lbsapi.API_KEY"
    android:value="用户的AK值" />
如果是用于定位，还需要添加服务

<service
    android:name="com.baidu.location.f"
    android:enabled="true"
    android:process=":remote"/>
第四步：AndroidStudio用户需要在build.grade中添加

sourceSets {
    main {
        jniLibs.srcDirs = ['libs']
    }
}

布局文件配置：
<com.baidu.mapapi.map.MapView
    android:id="@+id/bmapView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />
代码（含定位）：

    // 定位相关
    LocationClient mLocClient;
    public MyLocationListenner myListener = new MyLocationListenner();
    boolean isFirstLoc = true; // 是否首次定位
    String str = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        SDKInitializer.initialize(getApplicationContext());
        setContentView(R.layout.activity_baidu_map);

        mMapView = (MapView) findViewById(R.id.bmapView);
        findViewById(R.id.placechoose_btn).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Bundle bundle = new Bundle();
                bundle.putString("地址", str);
                Intent intent = new Intent(BaiduMapActivity.this, GoodsActivity.class);
                intent.putExtras(bundle);
                startActivity(intent);
                finish();
            }
        });

        mBaiduMap = mMapView.getMap();

        mBaiduMap.setMapType(BaiduMap.MAP_TYPE_NORMAL);

        if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION)
                != PackageManager.PERMISSION_GRANTED
                || ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
                != PackageManager.PERMISSION_GRANTED) {
            //申请WRITE_EXTERNAL_STORAGE权限
            ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.ACCESS_COARSE_LOCATION,
                            Manifest.permission.ACCESS_FINE_LOCATION},
                    ACCESS_COARSE_LOCATION_REQUEST_CODE);
        } else {
            init();
        }





    }

    private void init() {
        // 开启定位图层
        mBaiduMap.setMyLocationEnabled(true);
        // 定位初始化
        mLocClient = new LocationClient(this);
        mLocClient.registerLocationListener(myListener);
        LocationClientOption option = new LocationClientOption();
        option.setLocationMode(LocationClientOption.LocationMode.Hight_Accuracy);//设置高精度定位模式
        option.setOpenGps(true); // 打开gps
        option.setCoorType("bd09ll"); // 设置坐标类型
        option.setScanSpan(1000);
        option.setIsNeedAddress(true);//反编译获得具体位置，只有网络定位才可以
        mLocClient.setLocOption(option);
        mLocClient.start();
    }


    /**
     * 定位SDK监听函数
     */
    public class MyLocationListenner implements BDLocationListener {

        @Override
        public void onReceiveLocation(BDLocation location) {
            // map view 销毁后不在处理新接收的位置
            if (location == null || mMapView == null) {
                return;
            }
            MyLocationData locData = new MyLocationData.Builder()
                    .accuracy(location.getRadius())
                    // 此处设置开发者获取到的方向信息，顺时针0-360

                LatLng ll = new LatLng(location.getLatitude(),
                        location.getLongitude());
                MapStatus.Builder builder = new MapStatus.Builder();
                builder.target(ll).zoom(18.0f);
                mBaiduMap.animateMapStatus(MapStatusUpdateFactory.newMapStatus(builder.build()));
            }
            if(location.getLocType() == BDLocation.TypeGpsLocation){
                str = location.getAddrStr();
            }else if(location.getLocType() == BDLocation.TypeNetWorkLocation){
                str = location.getAddrStr();
            }

        }

        public void onReceivePoi(BDLocation poiLocation) {
        }
    }
    @Override
    protected void onDestroy() {
        super.onDestroy();

        // 退出时销毁定位
        mLocClient.stop();
        // 关闭定位图层
        mBaiduMap.setMyLocationEnabled(false);
        //在activity执行onDestroy时执行mMapView.onDestroy()，实现地图生命周期管理
        mMapView.onDestroy();
        mMapView = null;
    }

    @Override

        super.onResume();
        //在activity执行onResume时执行mMapView. onResume ()，实现地图生命周期管理
        mMapView.onResume();
    }

    @Override

        super.onPause();
        //在activity执行onPause时执行mMapView. onPause ()，实现地图生命周期管理
        mMapView.onPause();
    }

}
好的，大功告成
