我正在做我的毕业论文，我必须做一个 Android 应用程序，它会在谷歌地图上显示我的位置（我已经做过），当我点击大学中的一些图钉时，会弹出一些建筑物的信息，如果我可以的话我单击它们，它们将重定向到一个 url。我已经用 Toast 完成了它，但它并没有满足我的需求。我已经搜索并发现 NooYawk 弹出。这是我的代码，如果有人可以提供帮助，我将不胜感激。ps 我是业余的

public class TGpsActivity extends MapActivity {

弹出菜单的代码更多，但我不想显示 l

@Override
protected boolean onTap(int i) {
  OverlayItem item=getItem(i);
  GeoPoint geo=item.getPoint();
  Point pt=map.getProjection().toPixels(geo, null);

  View view=panel.getView();

  ((TextView)view.findViewById(R.id.latitude))
    .setText(String.valueOf(geo.getLatitudeE6()/1000000.0));
  ((TextView)view.findViewById(R.id.longitude))
    .setText(String.valueOf(geo.getLongitudeE6()/1000000.0));
  ((TextView)view.findViewById(R.id.x))
                          .setText(String.valueOf(pt.x));
  ((TextView)view.findViewById(R.id.y))
                          .setText(String.valueOf(pt.y));

  panel.show(pt.y*2>map.getHeight());

  return(true);
}

@Override
public int size() {
  return(items.size());}}
class PopupPanel {
View popup;
boolean isVisible=false;

PopupPanel(int layout) {
  ViewGroup parent=(ViewGroup)map.getParent();

  popup=getLayoutInflater().inflate(layout, parent, false);

  popup.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
      hide();
    }
  });
}

View getView() {
  return(popup);
}

void show(boolean alignTop) {
  RelativeLayout.LayoutParams lp=new RelativeLayout.LayoutParams(
        RelativeLayout.LayoutParams.WRAP_CONTENT,
        RelativeLayout.LayoutParams.WRAP_CONTENT
  );

  if (alignTop) {
    lp.addRule(RelativeLayout.ALIGN_PARENT_TOP);
    lp.setMargins(0, 20, 0, 0);
  }
  else {
    lp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
    lp.setMargins(0, 0, 0, 60);
  }

  hide();

  ((ViewGroup)map.getParent()).addView(popup, lp);
  isVisible=true;
}

void hide() {
  if (isVisible) {
    isVisible=false;
    ((ViewGroup)popup.getParent()).removeView(popup);
  }
}

尝试在您的位置上添加一个 OnTouchListener 并使用 Layout Inflator 显示带有您想要显示的信息的自定义布局。
