高德地图搜索提示获取信息回传activity刷新ui(二)
提示：扫一扫查出行【扫一扫了解最新限行尾号】
复制提示
应用场景：
在主activity中点击进入到另一个activity搜索提示，获取经纬度，点确定返回到主activity，虽然说需求很奇葩，但是遇到了没办法。。
主要包含两部分，搜索提示+activity回退携带信息刷新主acitivity.
1>搜索提示 代码中贴到
2>activity进入到另一个activity，在另一个activity进行操作获取数据之后，回到到activity刷新页面：
主activity里面点击：
Intent intent = new Intent(MainActivity.this,
SearchActivity.class);
startActivityForResult(intent, 0);//相当于addFlag
根据对生命周期的理解，重写
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
try {
if (data != null) {//获取子activity put的数据
String str = data.getStringExtra("addressName");
mAddress.setText(str);
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
=======
另一个activity里面：
/**
* 向主activity携带的地址信息
*/
Intent intent = new Intent(SearchActivity.this,
MainActivity.class);
intent.putExtra("addressName", str);//自己放数据
setResult(RESULT_OK, intent);
finish();

注意修改key,有错误还望指正，谢谢。
