在onActivityResult空意图演员 [英] Empty intent extras in onActivityResult

问题描述

我有两个活动。

第一第二调用是这样的：

First calls second like this:

Intent intent = new Intent(this, Second.class);
startActivityForResult(intent, 1);

在第二个返回数据：

Intent intent = new Intent();
intent.putExtra("a", "la-la-la");
setResult(RESULT_OK, intent);
finish();

和尝试收到第一项活动这个数据：

and trying to receive this data in first activity:

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

super.onActivityResult(requestCode, resultCode, data);

        if ((resultCode == Activity.RESULT_OK) && (currentTask != null)) {
            //Here is empty intent extas!!!

            Log.d("OrderActivity", "RESULT!!");
        }
    }

因此​​，请求code和响应code返回，但额外的意图是空??

So, request code and response code returned, but intent extra is empty..??

推荐答案

只是调用super.onFinish（前称此行）或任何你退出previous活动

Just call this lines before calling super.onFinish() or wherever you exit the previous activity

Intent intent = getIntent();
intent.putExtra("Date",dateSelected);
setResult(RESULT_OK, intent);
