問題描述

我使用了以下代碼，請求許可的對話框按預期顯示.但是當我單擊允許"時，它什么也不做.日志消息似乎沒有被授予權限，所以我去我的參數來驗證位置是否打開"并且它是關閉".它不應該是因為我授予應用程序訪問我的位置的權限嗎?如果我手動將其打開"然后再次運行該應用程序，一旦它請求我的許可，它就會工作并顯示日志消息，但并不是請求權限(通過對話)打開位置(當它關閉)如果用戶點擊允許"?難道我做錯了什么 ?我應該提到我正在 api23 上運行應用程序

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中的代碼:

 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

這是我的 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 + "");
            }

    }

推薦答案

試試這個代碼:

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);

<小時>

@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);
}

您將需要 Manifest.xml 的此權限:

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" />
