来自 HomeActivity 我正在尝试从 CreateProfileActivity 获取结果。这是我开始 Activity 的方法

Intent createProfile = new Intent(this, CreatePreacherActivity.class);
startActivityForResult(createProfile, 1);

这里是HomeActivity中onActivityResult方法的实现:

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {


        if (requestCode == 1)
        {

            Log.d("DEV","HomeActivity is reciving data");
            if (resultCode == RESULT_OK)
            {

                // this code here execute at the second call
                // but why there are two calls when i just call setResult once???

                User user = new User();

                String[] userInfo = data.getStringArrayExtra("preacher");

                //parsing and saving and database code...

                Log.d("DEV","HomeActivity data received->"+user);

                CurrentUser.set(this, user);
                fillCurrentUserInforms();
            }

            // if while searching for the preacher list
            // and none was found on database. Then tell the user
            // to create a new profile
            else if (resultCode == RESULT_CANCELED)
            {
                Intent createPreacherIntent = new Intent( this, CreatePreacherActivity.class );
                startActivityForResult(createPreacherIntent,1);
            }
        }

当我完成并在 CreateProfileActivity 中按 save 时，这是我将数据发送回 HomeActivity 的操作:

**private void createProfile()
{
   // some parsing and inserting the new data code..
    User u = new User();
    u.setName(newPreacher.getName());
    u.setLastName(newPreacher.getLastName());
    u.setId(newPreacher.getId());
    u.setSex(newPreacher.getSex());
    CurrentUser.set(this,u);
    if (getParent() == null)
    {
        setResult(RESULT_OK,createPreacherDataIntent(newPreacher));
    }
    else
    {
        getParent().setResult(RESULT_OK,createPreacherDataIntent(newPreacher));
    }
    Log.d("DEV","Exiting from CreatePreacherActivity");
    finish();
}**

setResult 方法是在 CreateProfileActivity 上调用一次，但由于某些未知原因，当数据到达 HomeActivity.onActivityResult 方法时，执行了两次。第一个结果为 requestCode = 0，第二个结果为 requestCode = 1。之后，HomeActivity.onActivityResult 被执行，CreateProfileActivity 再次出现，因为第一次调用 requestCode 为 0。

那为什么onActivityResult执行了两次？？

什么是第一次调用 0 然后第二次调用 1？

注意:我已阅读以下问题以查看我是否做错了什么但我可以看到它:

Android onActivityResult is always 0

fragments startActivityForResult always return resultCode 0 and intent null on callback onActivityResult

And more..

更新:

这是我的 list

最佳答案

删除

super.onActivityResult(requestCode, resultCode, data);

来自您 Activity 的 onActivityResult 方法。
