There are two methods to achieve your goal:

Method 1

Implement the GestureDetector.OnDoubleTapListener like this:

@Override
public boolean onSingleTapConfirmed(MotionEvent e) {
  return false; //Nothing
}

@Override
public boolean onDoubleTap(MotionEvent e) {
  //Indicates that this implementation has handled the double tap.
  return true;
}

@Override
public boolean onDoubleTapEvent(MotionEvent e) {
  //Indicates that this implementation has handled the double tap.
  return true;
}

and attach it to your GestureDetector like this:

gestureDetector.setOnDoubleTapListener(this);

Method 2

You can also use the WebSettings.setUseWideViewPort(false); and calculate the size of your view manually.

These methods should help you to achieve non-zoomable webviews that display everything.

public int getWindowWidth(Activity activity) {
  Display display = ((WindowManager) activity.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
  Point size = new Point();
  display.getSize(size);
  int width = size.x;
  return width;
}

public int getInitialScale(Activity activity, int websiteWidth) {
  return (getWindowWidth(activity) / websiteWidth) * 100;
}
