尝试在Android Studio中请求具有位置权限的对话框，但它不起作用

Question

I'm trying to request a dialog with the location permission to activate it, but I don't know how to do it exactly.. If you can help me, thanks.

This is my full code:

public class DialogEntrar extends BlurDialogFragment implements GoogleApiClient.OnConnectionFailedListener,
    GoogleApiClient.ConnectionCallbacks,
    LocationListener {
private static final String TAG = DialogEntrar.class.getSimpleName();
private SignInButton btnSignInGlg;

static GoogleApiClient apiClient;
private static final int RC_SIGN_IN = 1001;



private static final String LOGTAG = "android-localizacion";

private static final int PETICION_PERMISO_LOCALIZACION = 101;
private static final int PETICION_CONFIG_UBICACION = 201;

private ProgressDialog progressDialog;

private View v;

//Datos de usuario entrado
String personName;
String personGivenName;
String personFamilyName;
String personEmail;
String personId;
Uri personPhoto;

public DialogEntrar() {
}

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    return createLoginDialogo();
}

@Override
public void onDestroy() {
    super.onDestroy();
    apiClient.stopAutoManage((FragmentActivity) getActivity());
    apiClient.disconnect();
}

//Lo que sale una vez apretas el boton de jugar
private void showProgressDialog() {
    if (progressDialog == null) {
        progressDialog = new ProgressDialog(getActivity());
        progressDialog.setMessage(getResources().getString(R.string.Entrando));
        progressDialog.setIndeterminate(true);

    }
    progressDialog.show();
}

private void hideProgressDialog() {
    if (progressDialog != null && progressDialog.isShowing()) {
        progressDialog.hide();
    }
}

public AlertDialog createLoginDialogo() {

    //ROLLO DE LA API DE GOOGLE SIGN IN
    GoogleSignInOptions gso =
            new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                    .requestEmail()
                    .build();

    apiClient = new GoogleApiClient.Builder(getActivity())
            .enableAutoManage((FragmentActivity) getActivity(), this)
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso).addApi(LocationServices.API)
            .build();

It just, don't show the dialog and I don't know why.. If you can help me, thanks..

Answer 1

The method onConnected() is never called because you need to call it by using the method connect() .

public abstract void connect ()

Connects the client to Google Play services. This method returns immediately, and connects to the service in the background. If the connection is successful, onConnected(Bundle) is called and enqueued items are executed. On a failure, onConnectionFailed(ConnectionResult) is called.

If the client is already connected or connecting, this method does nothing.

For example in your code you need to include: apiClient.connect();

Start a manually managed connection:

In an activity context the best practice is to call connect() in your activity's onStart() method and disconnect() in your activity's onStop() method.
