Android集成百度地图遇到地图不显示小蓝点的解决方法

1.集成百度地图SDK时，遇到了好几个问题？
1集成后，点击闪退报错是因为，没有同意隐私政策，造成了闪退
解决方法：需要在setContentView之前实现这两个方法
SDKInitializer.setAgreePrivacy(getApplicationContext(), true);

SDKInitializer.initialize(getApplicationContext());
2.集成地图功能，没有出现定位小蓝点的原因
是对Api不熟悉，在使用MapStatusUpdate方法 实现地图zoomTo的方法，造成了

mBaiduMap.animateMapStatus(update);
这个方法失效，导致没有定位到当前为止显示小蓝点
作为小白，也是花了大量的时间在百度上，而没有研究API使用方法，在出现问题时，切记要先看方法本身，实在解决不了的在进行百度
以下是完整实现
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.d(TAG, "onCreate: 百度地图SDK初始化");
SDKInitializer.setAgreePrivacy(getApplicationContext(), true);

    SDKInitializer.initialize(getApplicationContext());
    initLoc();
    setContentView(R.layout.activity_lbs_map);

    locText = (TextView) findViewById(R.id.position_text_view);
    mapView = (MapView)findViewById(R.id.map_view);
    mBaiduMap = mapView.getMap();
    mBaiduMap.setMyLocationEnabled(true);
    checkPermission();

}

private void checkPermission() {
    List<String> permissionList = new ArrayList<>();
    if (ContextCompat.checkSelfPermission(BDMapActivity.this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED){

    }

    if (ContextCompat.checkSelfPermission(BDMapActivity.this, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {

        permissionList.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);
    }
    if (!permissionList.isEmpty()) {
        String[] permissions = permissionList.toArray(new String[permissionList.size()]);
        ActivityCompat.requestPermissions(BDMapActivity.this, permissions, 1);
    }else {
        requestLocation();
    }
}



private void initLoc() {

    LocationClient.setAgreePrivacy(true);

    // 定位初始化
    try {
        mLocationClient = new LocationClient(this);
    } catch (Exception e) {
        e.printStackTrace();
    }

    if (mLocationClient != null){
        Log.d(TAG, "initLoc: 地图注册监听事件");
        mLocationClient.registerLocationListener(new MyLocationListener());
    }





}

private void requestLocation() {

    Log.d(TAG, "requestLocation: 开始定位");
    initLocation();

}

private void initLocation() {

    LocationClientOption option = new LocationClientOption();
    option.setScanSpan(5000);// 5秒更新一次位置信息
    option.setIsNeedAddress(true); // 返回地址信息
    option.setOpenGps(true);
    option.setCoorType("bd09ll");
    mLocationClient.setLocOption(option);
    
    // 开启地图定位图层
    mLocationClient.start();
    Log.d(TAG, "initLocation: 开启定位图层");
