传递数据的话使用intent
Intent intent = new Intent(context, XXX.class);
intent.putExtra("XX",XX);
startActivity(intent);
至于设置坐标的话去看下百度地图的api把

谢谢这个传递数据我会用就是不知道怎么在地图里用
在oncreate方法里面 //定义经纬度:安徽商贸职业技术学院
        GeoPoint geoPoint = new GeoPoint((int) (31.294468 * 1E6),
                (int) (118.374291 * 1E6));
        //设置getPoint为中心点
此设置之前可以创建两个变量记录经纬度默认值就是你的实际坐标如果有传递过来经纬的话就使用传递过来没有就是默认的

嗯嗯谢谢很好的思路

Intent 回传不就好了把坐标传回来之后重新设置 GeoPoint 再调用地图的refresh（）函数刷新地图就行了

是的
我已经用intent把值传过来了而且也接收到了但是不知道为什么没效果呢

startActivity(intentSearchCity);
} else {
Toast.makeText(SearchCity.this, "请输入地址信息", Toast.LENGTH_SHORT)
.show();
}
}
}

上层楼SearchActivity中 36、37行贴错了是if (inputSearchCity_city.getText() != null
&& inputSearchCity_geocodekey.getText() != null)

调试易
