Question

我正在尝试调用另一个文件的过程。到目前为止，我得到的结果是一个错误：

test.p

GeoQueryDataEventListener

sumWords.p

public class GeofireActivity extends AppCompatActivity {

    private static final String LOG_TAG = GeofireActivity.class.getSimpleName();

    private DatabaseReference refBase     = null;
    private DatabaseReference refLocation = null;
    private DatabaseReference refUser     = null;

    private GeoFire geoFire = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.setContentView(R.layout.fragment_geofire);
        this.setReferences();
    }

    private void setReferences() {
        this.refBase = FirebaseDatabase.getInstance().getReference();
        this.refUser = refBase.child("users");
        this.refLocation = refBase.child("locations");
        this.geoFire = new GeoFire(this.refLocation);
    }

    private void searchNearby(double latitude, double longitude, double radius) {
        this.searchNearby(new GeoLocation(latitude, longitude), radius);
    }

    private void searchNearby(GeoLocation location, double radius) {

        GeoQuery geoQuery = this.geoFire.queryAtLocation(location, radius);
        geoQuery.addGeoQueryEventListener(new GeoQueryEventListener() {

            @Override
            public void onKeyEntered(String key, GeoLocation location) {

                String loc = String.valueOf(location.latitude) + ", " + String.valueOf(location.longitude);
                Log.d(LOG_TAG, "onKeyEntered: " + key + " @ " + loc);

                /* once the key is known, one can lookup the associated record */
                refUser.child(key).addListenerForSingleValueEvent(new ValueEventListener() {

                    @Override
                    public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
                        Log.d(LOG_TAG, "onDataChange: " + dataSnapshot.toString());
                    }

                    @Override
                    public void onCancelled(@NonNull DatabaseError firebaseError) {
                        Log.e(LOG_TAG, "onCancelled: " + firebaseError.getMessage());
                    }
                });
            }

            @Override
            public void onKeyExited(String key) {
                Log.d(LOG_TAG, "onKeyExited: " + key);
            }

            @Override
            public void onKeyMoved(String key, GeoLocation location) {
                Log.d(LOG_TAG, "onKeyMoved: " + key);
            }

            @Override
            public void onGeoQueryReady() {
                Log.d(LOG_TAG, "onGeoQueryReady");
            }

            @Override
            public void onGeoQueryError(DatabaseError error) {
                Log.e(LOG_TAG, "onGeoQueryError" + error.getMessage());
            }
        });
    }
}

test.p将参数传递给了sumWords.p，它没有任何要求。（1005）

Answer 1

您已经在“ sumWords.p”中创建了一个内部过程“ sumWords”。 sumWords.p确实不需要参数。

更改sumWords.p并删除行PROCEDURE sumWords:和END PROCEDURE.

那样，sumWords.p需要参数。

或更改呼叫者：

DEFINE VARIABLE hSumWords AS HANDLE NO-UNDO.

RUN sumWords.p PERSISTENT SET hSumWords. 

RUN sumWords IN hSumWords (INPUT "Hello", INPUT "World", OUTPUT tmp).

DELETE OBJECT hSumWords.
