我有一个通过
拨号的动作uri = Uri.parse("tel:" + address);
Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(uri);
PendingIntent pd = PendingIntent.getActivity(context, 0,intent,
PendingIntent.FLAG_UPDATE_CURRENT);
notif.addAction(R.drawable.ic_menu_call, "Call", pd);
但问题是我不知道
如何/何时调用NotificationManager的manager.cancel()
函数
以便在点击通话操作时解除通知!
答案 0 :(得分:0)
请参阅Android READ PHONE STATE? - 关于手机状态。
case TelephonyManager.CALL_STATE_RINGING:
notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.cancel(100); // cancel notification by ID
break;
//建立你的通知。
intent notificationIntent = new Intent(context,
YourPhoneActivity.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent = PendingIntent.getActivity(context, 0,
notificationIntent, 0);
Bitmap bm = BitmapFactory.decodeResource(context.getResources(),
iconLarge);
NotificationCompat.Builder builder = new NotificationCompat.Builder(
context).setSmallIcon(iconSmall).setLargeIcon(bm)
.setContentTitle(title).setContentText(message)
.setAutoCancel(false).setContentIntent(intent).setWhen(when)
.setTicker(message);
builder.getNotification();

我遇到了同样的情况,我设法通过创建一个广播接收器来解决它,该广播接收器在按下操作按钮时被调用。然后,广播接收器会收到一个意图,其中包含您要取消的通知ID和您要拨打的号码。
这是创建通知的代码:
NotificationManager notificationManager =
(NotificationManager)MyApplication.getAppContext().getSystemService(Context.NOTIFICATION_SERVICE);
//for some versions of android you may need to create a channel with the id you want
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel chan = new NotificationChannel("your_channel_id", "ChannelName", NotificationManager.IMPORTANCE_DEFAULT);
notificationManager.createNotificationChannel(chan);
}
Intent intent = new Intent(MyApplication.getAppContext(), ActionReciever.class);
intent.putExtra("phoNo", phoneNumber);
// num is the notification id
intent.putExtra("id", num);
PendingIntent myPendingIntent = PendingIntent.getBroadcast(
MyApplication.getAppContext(), 0, intent, PendingIntent.FLAG_UPDATE_CURRENT
);
Notification n = new NotificationCompat.Builder(MyApplication.getAppContext(),
"your_channel_id")
.setSmallIcon(R.drawable.app_pic)
.addAction(R.drawable.app_pic, "Dial now", myPendingIntent)
.setAutoCancel(true)
.build();
notificationManager.notify(num, n);
这是广播接收器代码,按下操作按钮时将被调用。此处收到的意图是我们在通知中准备的未决意图内的意图:
public class ActionReciever extends BroadcastReceiver {
@SuppressLint("MissingPermission")
@Override
public void onReceive(Context context, Intent intent) {
String phoneNumber = intent.getStringExtra("phoNo");
int id = intent.getIntExtra("id",0);
Intent i = new Intent(Intent.ACTION_DIAL);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.setData(Uri.parse("tel:" + phoneNumber));
NotificationManager notificationManager =
(NotificationManager) MyApplication.getAppContext().getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.cancel(id);
context.startActivity(i);
}
}
在应用标签中的应用清单中注册BroadcastReceiver
<receiver android:name=".ActionReciever" />
MyApplication是扩展默认Application的类,因此我可以在某个地方存储所需的上下文。
public class MyApplication extends Application {
private static Context context;
public void onCreate() {
super.onCreate();
MyApplication.context = getApplicationContext();
}
public static Context getAppContext() {
return MyApplication.context;
}
}
请注意,您需要更新清单才能运行MyApplication类:
android:name="com.example.yourpackage.MyApplication"
即使应用程序关闭且没有后台服务,此代码也可以正常工作。
