android 百度地图 搜索跳转

一共有两个Activity ,第一个Activity显示地图,实现定位当前地址并输出在第一个页面的EditText里,第二个Activity是搜索页面,搜索框是EditText,ListView显示搜索结果,使用百度地图建议搜索功能。比如搜索一个万达广场,点击搜索结果后希望在第一个Activity的地图上显示当前定位地址和到万达广场的路线规划,就是起点和终点显示出来。
(这里需要起点自动获取,因为地图已经实现自动定位当前地址了,不要那种既要输入起点,又要输入终点,最后还得要点击一下确定,才会显示结果的那种无语的操作体验,整个软件是没有一个Bundle按钮的,只需要item)
现在的问题是点击第二个页面ListView里面的搜索结果万达广场,跳转到第一个页面之后没有任何反应。
谢谢各位大神哥哥姐姐~

第一个activity里有在oncreate()或者onNewIntent()对传进来的intent做处理吗,或者你是用startactivityforresult 的话要实现onActivityResult方法

qq_41202319 我里面的intent纯属瞎写,完全不懂。。

qq_41202319 嗯,使用的就是intent进行跳转传送数据,startActivityForResult也写了,就是不知道具体的代码怎么实现,你一句话就说中了,就是不知道怎么传送,还有要怎么接收,总是调不对

最好贴贴代码,才能看出问题所在

switch (requestCode){
case RESULT_OK:
Bundle bundle=data.getExtras();
String str=bundle.getString("backData");
Toast.makeText(MainActivity.this, str,Toast.LENGTH_LONG).show();
break;

    default:
        break;
}


    这段代码上面的requestCode改成resultCode,requestCode是你startActivityForResult发过的请求码
    ,不是返回过来的结果码,你这里requestCode写的1,返回过来的resultCode是result_ok=-1,所以会没跑那段代码
