试试这个。

您不能使用 ACTION_DATE_CHANGED，因为它是私有 android 操作，因此您需要创建自定义操作。

 <receiver
            android:name=".MyReceiver"
            android:exported="false">
            <intent-filter>
                <action android:name="${applicationId}.receiver.RECEIVE_MESSAGE_ACTION" />
            </intent-filter>
        </receiver>

那么您需要先注册您的 activity 才能使用它。通常，我放在 onCreate 方法中。

private fun registerReceiver(){
        val filter = IntentFilter()
        filter.addAction(MyReceiver.RECEIVE_MESSAGE_ACTION)

        val customReceiver = MyReceiver()
        registerReceiver(customReceiver, filter)
    }

当您打电话分享您的消息时，请使用以下代码。

companion object {
        const val RECEIVE_MESSAGE_ACTION = "${BuildConfig.APPLICATION_ID}.receiver.RECEIVE_MESSAGE_ACTION"
    }

private fun callCustomBroadcast(message: String) {
        val intent = Intent(RECEIVE_MESSAGE_ACTION)
        intent.putExtra("mymessage", message)
        sendBroadcast(intent)
    }
