Question

我在清单文件中添加了一些像AACTION_POWER_CONNECTED的迭代，我希望在连接充电器时获得通知。这是我的代码。

    public class AwesomeReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Toast.makeText(context, "Inside onReceive", Toast.LENGTH_LONG).show();
        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context);
        mBuilder.setSmallIcon(R.drawable.ic_launcher);
        mBuilder.setContentTitle("This is A Notification");
        mBuilder.build();

    }
}

每次连接充电器但未收到通知时，我都会收到Toast。由于我是Android的新手，我不知道如何实现这一目标。

试试这段代码：

public class AwesomeReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Toast.makeText(context, "Inside onReceive", Toast.LENGTH_LONG).show();
        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context);
        mBuilder.setSmallIcon(R.drawable.ic_launcher);
        mBuilder.setContentTitle("This is A Notification");

        NotificationManager mNotificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        mNotificationManager.notify(mId, mBuilder.build());
    }
}

其实你创建了Notification对象但从未解雇它:) 因此，您只需要与notify()保持联系。
