无法在 android api 23 上打开位置？

我使用了以下代码，请求许可的对话按预期显示。但当我点击“允许”时，它什么也没做。日志消息不会显示为好像未授予权限，因此我转到参数来验证位置是否为“打开”以及“关闭”。难道不是因为我授予应用程序访问我的位置的权限而应该打开它吗？ 如果我手动“打开”它，然后再次运行该应用程序，一旦它请求我的许可，它就会工作并显示日志消息，但这并不是请求权限（通过对话）来打开位置的全部意义（当它关闭）如果用户单击“允许”？ 难道我做错了什么 ？我应该提到我正在 api23 上运行该应用程序

是我的代码Oncreate:

 mApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();

 mApiClient.connect();

    // Create the LocationRequest object
        mLocationRequest = LocationRequest.create()
                .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
                .setInterval(10 * 1000)        // 10 seconds, in milliseconds
                .setFastestInterval(1 * 1000); // 1 second, in milliseconds

这是我的已连接 method:

    public void onConnected(@Nullable Bundle bundle) {
            //start the service
//checking and asking for permission

            if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
                if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
                    ActivityCompat.requestPermissions(this,
                            new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
                            MY_PERMISSION_ACCESS_FINE_LOCATION);
                }
                //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
                //                                          int[] grantResults)
                // to handle the case where the user grants the permission. See the documentation
                // for ActivityCompat#requestPermissions for more details.
                return;
            }
            Location location = LocationServices.FusedLocationApi.getLastLocation(mApiClient);

            if (location == null) {
                LocationServices.FusedLocationApi.requestLocationUpdates(mApiClient, mLocationRequest, this);

            } else {
                //If everything went fine lets get latitude and longitude
                currentLatitude = location.getLatitude();
                currentLongitude = location.getLongitude();
                Log.v("currentLatitude",currentLatitude + " WORKS " + currentLongitude + "");
            }

    }

试试这个代码：

private LocationCoord gps = null;
private static final int PERMISSION_REQUEST_CODE = 1;

在 OnCreate() 中：

//GPS Manage
    LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    boolean gps_enabled = false;
    boolean network_enabled = false;

    try {
        gps_enabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
    } catch (Exception ex) {
    }

    try {
        network_enabled = lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
    } catch (Exception ex) {
    }

    if (!gps_enabled && !network_enabled) {
        // notify user
        AlertDialog.Builder dialog = new AlertDialog.Builder(this);
        dialog.setMessage("Allow ImHere to access this device's location?");
        dialog.setPositiveButton("Allow", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface paramDialogInterface, int paramInt) {
                // TODO Auto-generated method stub
                Intent myIntent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                startActivity(myIntent);
                //get gps
            }
        });
        dialog.setNegativeButton("Deny", new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface paramDialogInterface, int paramInt) {
                // TODO Auto-generated method stub

            }
        });
        dialog.show();
    }

    gps = new LocationCoord(this);

@Override
protected void onStart() {
    super.onStart();

    // permission android 6.0
    if (!checkPermission()) {
        requestPermission();
    }

}


private boolean checkPermission(){
    int result = ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION);
    if (result == PackageManager.PERMISSION_GRANTED) return true;
    else return false;
}

private void requestPermission(){
    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, PERMISSION_REQUEST_CODE);
}

您需要对 Manifest.xml 具有此权限：

<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
