目前，我正在建立一个应用程序，将显示用户最近的预测。为了进行api调用，我必须提供经度和纬度作为参数。目前，我已经编写了一些关于获取语言度和经度的代码，但是我没有收到正确的数据。当我在mainactivity中编写这些方法时，首先，经度和纬度等于0.0，大约两秒钟后，它就能够获得正确的数据。我应该冻结应用程序直到locationmanage获得正确的数据，还是应该在其他地方调用这些方法？我应该给他们打电话吗？
正在检查权限

if (ContextCompat.checkSelfPermission(
            getApplicationContext(), Manifest.permission.INTERNET) == PackageManager.PERMISSION_GRANTED &&
            ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED &&
            ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
        mLocationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
        mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);

    } else {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            requestPermissions(new String[]{
                    Manifest.permission.INTERNET, Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION

            }, 1);
        }
    }
}

OnLocation已更改

@Override
public void onLocationChanged(@NonNull Location location) {
    mLatitude = location.getLatitude();
    mLongitude = location.getLongitude();

    Log.i(TAG, "onLocationChanged: "+mLatitude+" "+mLongitude);
}

在存储库中

public static double mLatitude = MainActivity.mLatitude;
public static double mLongitude = MainActivity.mLongitude;

public ForecastRepository(){
    mApi = RetrofitBuilder.makeCall();
}

public MutableLiveData<ForecastModel> testCall() {
    MutableLiveData<ForecastModel> data = new MutableLiveData<>();

    //TODO temporary values such as latitude/longitude in api call
    mApi.test(mLatitude, mLongitude, "metric", API_KEY).enqueue(new Callback<ForecastModel>() {
        @Override
        public void onResponse(Call<ForecastModel> call, Response<ForecastModel> response) {
            if (!response.isSuccessful()){
                Log.i(TAG, "onResponse: "+ response.code());
            }
            Log.i(TAG, "onResponse: successful "+mLatitude+" "+mLongitude);
            data.setValue(response.body());
        }

        @Override
        public void onFailure(Call<ForecastModel> call, Throwable t) {
            Log.i(TAG, "onFailure: "+t.getMessage());
        }
    });
    return data;
}
}
