Question

我在我的手机中使用mapbox来获取当前位置，但有时它会显示标记，而在logcat中它显示为java.lang.IllegalStateException：GoogleApiClient尚未连接。

注意当我在logcat中单击该行时，它将转到此代码

@Override
    public void onConnected(@Nullable Bundle bundle) {

            if (ActivityCompat.checkSelfPermission(getApplicationContext(), android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getApplicationContext(), android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

                return;
            }
            if (mGoogleApiClient != null) {
                mGoogleApiClient.connect();
            }
            LocationServices.FusedLocationApi.requestLocationUpdates(
                    mGoogleApiClient,
                    REQUEST,
                    this);  // LocationListener

    }

这是我的java代码：

public class ClockInDetails extends Fragment implements GoogleApiClient.ConnectionCallbacks,GoogleApiClient.OnConnectionFailedListener, LocationListener {
    private MapboxMap mMapBoxMap;
    private GoogleApiClient mGoogleApiClient = null;
    private LatLng gs_var_mLatLng;
    private MarkerOptions mMarker;
LocationRequest mLocationRequest;
    protected void createLocationRequest() {
        mLocationRequest = new LocationRequest();
        mLocationRequest.setInterval(5000);
        mLocationRequest.setFastestInterval(5000);
        mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    }
    private static final LocationRequest REQUEST = LocationRequest.create()
            .setInterval(5000)
            .setFastestInterval(5000)
            .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    public ClockInDetails() {
        // Required empty public constructor
    }
    public static boolean isGPSEnabled = false;
    public static boolean isNetworkEnabled = false;
@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.fragment_clock_in_details, container, false);
        try {
            gs_mapView = (MapView)view.findViewById(R.id.gs_mapView);
            //to check gps is enabled or not

            gs_mapView.onCreate(savedInstanceState);
            //mapbox view to display current locations by calling buildgooglepaiclient
            gs_mapView.getMapAsync(new OnMapReadyCallback() {
                @Override
                public void onMapReady(MapboxMap mapboxMap) {
                    mMapBoxMap = mapboxMap;
                    buildGoogleApiClient();
                    mapboxMap.setMyLocationEnabled(true);

                }
            });
            locationManager = (LocationManager) getContext().getSystemService(LOCATION_SERVICE);
            isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);

            if (!isGPSEnabled && !isNetworkEnabled) {
                final Dialog dialog = new Dialog(getContext());
                dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
                dialog.setCancelable(false);
                dialog.setContentView(R.layout.layout_confirmation);

                tv_alert_Message.setText("GPS has been disabled in your device. Please enable it?");

                Button btn_cancel = (Button) dialog.findViewById(R.id.cancel);


                btn_cancel.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        dialog.dismiss();
                    }
                });

                btn_submit.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        Intent callGPSSettingIntent = new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                        getContext().startActivity(callGPSSettingIntent);


                        buildGoogleApiClient();

                        dialog.dismiss();
                    }

            // other 'case' lines to check for other
            // permissions this app might request
        }
    }

}

我不知道为什么它没有显示，即使该位置已开启，我已连接googleApiClient中的onStart()，onResume()，但为什么它显示未连接.Marker不是在地图上显示。请帮我一个人。在Android 4.4中我有一个警告来检查gps是否启用弹出窗口没有显示。请帮助我，我做了什么错误，但有时候标记它显示如何？

在应用mGoogleApiClient.connect（）之前;你应该添加一个空检查，即你的代码应该是这样的：

if(mGoogleApiClient!=null)
     mGoogleApiClient.connect();

java.lang.IllegalStateException：GoogleApiClient尚未连接。在地图页面不正确
