无法在android api23上打开位置?

问题描述

我使用了以下代码，请求许可的对话框按预期显示.但是当我单击允许"时，它什么也不做.日志消息似乎没有被授予权限，所以我去我的参数来验证位置是否打开"并且它是关闭".它不应该是因为我授予应用程序访问我的位置的权限吗?如果我手动将其打开"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，但并不是请求权限(通过对话)打开位置(当它关闭)如果用户点击允许"?难道我做错了什么 ?我应该提到我正在 api23 上运行应用程序

I have used the following code and the dialogue that asks for permission shows as expected. But when I click "allow" it doesn't do anything. The log message doesn't appear as if the permission wasn't granted so I went to my parameters to verify if location is "on" and it was "off". Wasn't it supposed to be on because I granted the app access to my location ? If I manually turn it "on" and then run the app again, once it asks for my permission, it works and shows the log message but isn't the whole point of asking for permissions (via dialogue) to turn on location (when it's off) if the user clicks "allow" ? Am I doing something wrong ? I should mention that I'm running the app on api23

是我的Oncreate中的代码:

 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 OnConnected 方法:

    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 + "");
            }

    }

推荐答案

试试这个代码:

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

在 OnCreate() 中:

In OnCreate():

//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);

<小时>

@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);
}

您将需要 Manifest.xml 的此权限:

You will need this permissions on the Manifest.xml:

<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" />
