最终显示效果
，利用经纬度对通过url跳转百度地图
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
Uri uri = Uri.parse("http://api.map.baidu.com/geocoder?location="+
DatasStatistics.getLatLng().latitude+","+DatasStatistics.getLatLng().longitude+"&coord_type=bd09ll&output=html&src=webapp.baidu.openAPIdemo");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);
}
});
