Here is my own code which i have written up till now. I am trying to
implement onDoubleTap() zoom in function in my application. My code is as
follows. LEt me know where is the problem ? and if possible please add the
correct code for double tap zoom in function.
public class Maps extends MapActivity implements OnGestureListener,
OnDoubleTapListener{
private GestureDetector detector;
MapView mapView;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//MapViewer mapViewer = new MapViewer(null, null);
mapView = (MapView) findViewById(R.id.mapview);
detector = new GestureDetector(this,this);
mapView.setBuiltInZoomControls(true);
}
@Override
protected boolean isRouteDisplayed() {
return false;
}
public boolean onDoubleTap(MotionEvent e) {
// TODO Auto-generated method stub
mapView.getController().zoomIn();
return false;
}
public boolean onDoubleTapEvent(MotionEvent e) {
// TODO Auto-generated method stub
return false;
}
public boolean onSingleTapConfirmed(MotionEvent e) {
// TODO Auto-generated method stub
return false;
}
public boolean onDown(MotionEvent e) {
// TODO Auto-generated method stub
return false;
}
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
float velocityY) {
// TODO Auto-generated method stub
return false;
}
public void onLongPress(MotionEvent e) {
// TODO Auto-generated method stub
}
public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX,
float distanceY) {
// TODO Auto-generated method stub
return false;
}
public void onShowPress(MotionEvent e) {
// TODO Auto-generated method stub
}
public boolean onSingleTapUp(MotionEvent e) {
// TODO Auto-generated method stub
return false;
}
}
