Android弹出信息框在点击百度地图时

如图：



我是在百度的demo上改的主要代码：

复制代码 package com.baidu.mapapi.demo; import java.util.ArrayList; import java.util.List; import android.content.Context; import android.content.Intent; import android.graphics.Canvas; import android.graphics.Color;

} app.mBMapMan.start(); // 如果使用地图SDK，请初始化地图Activity super.initMapActivity(app.mBMapMan); mMapView = (MapView) findViewById(R.id.bmapView); mMapView.setBuiltInZoomControls(true); // 设置在缩放动画过程中也显示overlay,默认为不绘制 mMapView.setDrawOverlayWhenZooming(true); GeoPoint point = new GeoPoint((int) (mLat1 * 1e6), (int) (mLon1 * 1e6)); mMapView.getController().setCenter(point); mMapView.getController().setZoom(17); // 添加ItemizedOverlay Drawable marker = getResources().getDrawable(R.drawable.iconmarka); // 得到需要标在地图上的资源 marker.setBounds(0, 0, marker.getIntrinsicWidth(), marker.getIntrinsicHeight()); // 为maker定义位置和边界 mMapView.getOverlays().add( new OverItemT(marker, this, mLat1, mLon1, temp)); // 添加ItemizedOverlay实例到mMapView initPopview();

} // 处理当点击事件 protected boolean onTap(int i) { setFocus(mGeoList.get(i)); MapView.LayoutParams geoLP = (MapView.LayoutParams) mContext.popView .getLayoutParams(); GeoPoint pt = mGeoList.get(i).getPoint(); mContext.mMapView.updateViewLayout(mContext.popView, new MapView.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, pt, MapView.LayoutParams.BOTTOM_CENTER)); mContext.popView.setVisibility(View.VISIBLE);

} }); return true; } @Override public boolean onTap(GeoPoint arg0, MapView arg1) { // TODO Auto-generated method stub return super.onTap(arg0, arg1); } }

整个包在附件中，记得自己申请key，好像这个弹出框也可以在谷歌地图上用。
