activity传值 onActivityResult的使用

第一步

Intent in=new Intent(context, WUserListDialog.class);
startActivityForResult(in,0);

第二步在WUserListDialog中 传值

Intent ins=new Intent();
ins.putExtra("username",list.get(i).getUsername());
ins.putExtra("cellphone",list.get(i).getCellphone());
setResult(1,ins);
finish();

第三步 在context（activity）中接受

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if(data!=null&requestCode==0){
        chs_wuser.setText(data.getStringExtra("username")+" -- "+data.getStringExtra("cellphone"));
        physicist_class=data.getStringExtra("cellphone");
    }
}
