我正在尝试从Cbreceiver.class传递一个名为'str'的字符串，它将广播接收器扩展到活动cbdata.java.but我无法传递该值，我也没有收到任何错误。谢谢。帮助我请这个

删除OnReceive（）方法使用
@Override
protected void onNewIntent(Intent intent) {
Log.d("YourActivity", "onNewIntent is called!");
memberFieldString = intent.getStringExtra("KEY");
super.onNewIntent(intent);
} // End of onNewIntent(Intent intent)

Cbreceiver rec = new Cbreceiver（this）;
然后直接使用字符串作为rec.str
