我正在尝试从 Cbrceiver.class 传递一个名为“str”的字符串，该字符串将广播接收器扩展到活动 cbdata.java。但我无法传递该值，我也没有收到任何错误。谢谢。请帮帮我

删除 OnRecieve() 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)

告诉我天气它的工作与否

您可以尝试在 Cbdata 中创建类 Cbrceiver 的对象...例如。

Cbrceiver rec = 新的 Cbrceiver(this);

然后直接使用字符串作为rec.str
