android - 显示未接 VOIP 呼叫的通知

Question

我没有找到这个问题的答案。我有一个 VOIP 应用程序。我可以在本地通话记录中添加有关未接来电的日志，但未显示通知。有没有办法让设备本机通话记录显示通知？我不想添加自己的通知，因为我想确保图标始终是本机呼叫日志应用程序将为其他呼叫显示的图标。

我找到了这个，但没有答案。我使用的代码类似于上一篇文章中显示的代码。

Answer 1

只是为了清楚起见：

您仍然可以添加自己的通知，但使用 android 系统内置图标 - 这些图标与内置电话应用程序使用的图标相同。例如：

    Notification notification = new Notification();
    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notification.icon = android.R.drawable.stat_notify_missed_call;

这样，您将始终显示特定 Android 操作系统版本特有的图标。

有关更多信息，请查看图标指南，尤其是在您的情况下 -状态栏图标。

Answer 2

如果您只是在通话记录数据库中添加一个条目，则不会显示通知。您需要添加您的通知。如果您不添加自己的通知，则只有在通话记录仍然存在的情况下，才会在电话启动时显示通知。

这是我的实现（主要是从android代码复制的）：

private static void showMissedCallNotification(Context context, final Contact contact) {
    notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    // display the first line of the notification:
    // 1 missed call: call name
    // more than 1 missed call: <number of calls> + "missed calls"
    int titleResId;
    String expandedText;
    numberMissedCalls++;
    if (numberMissedCalls == 1) {
        titleResId = R.string.notification_missedCallTitle;
        expandedText = contact.getDisplayName();
    } else {
        titleResId = R.string.notification_missedCallsTitle;
        expandedText = context.getString(R.string.notification_missedCallsMsg,
                numberMissedCalls);
    }
    final PendingIntent callLogIntent = createCallLogIntent(context);
    // make the notification
    int id = android.R.drawable.stat_notify_missed_call;
    String ticker = context.getString(R.string.notification_missedCallTicker, contact.getDisplayNumber());
    long currentTime = Platform.timeProvider().getTime();
    Notification note = new Notification(id, ticker, currentTime);
    note.setLatestEventInfo(context, context.getText(titleResId), expandedText, callLogIntent);
    note.flags |= Notification.FLAG_AUTO_CANCEL;
    // This intent will be called when the notification is dismissed.
    // It will take care of clearing the list of missed calls.
    note.deleteIntent = createClearMissedCallsIntent(context);

    //configureLedNotification(note);
    notificationManager.notify(MISSED_CALL_NOTIFICATION, note);
}

/**
 *  Returns an intent to be invoked when the missed call notification is clicked. 
 * @param context 
 */
private static PendingIntent createCallLogIntent(Context context) {
    Intent intent = new Intent(context, ClearMissedCallsService.class);
    intent.setAction(ClearMissedCallsService.ACTION_OPEN_CALL_LOGS);
    return PendingIntent.getService(context, 0, intent, 0);
}

/**
 *  Returns an intent to be invoked when the missed call notification is cleared. 
 * @param context 
 */
private static PendingIntent createClearMissedCallsIntent(Context context) {
    Intent intent = new Intent(context, ClearMissedCallsService.class);
    intent.setAction(ClearMissedCallsService.ACTION_CLEAR_MISSED_CALLS);
    return PendingIntent.getService(context, 0, intent, 0);
}

/*package */ static void cancelMissedCallNotification() {
    // reset the number of missed calls to 0.
    numberMissedCalls = 0;
    notificationManager.cancel(MISSED_CALL_NOTIFICATION);
}   

和：

/**
 * Handles the intent to clear the missed calls that is triggered when a notification is dismissed.
 */
public class ClearMissedCallsService extends IntentService {
    /** This action is used to clear missed calls. */
    public static final String ACTION_CLEAR_MISSED_CALLS = "com.android.phone.intent.CLEAR_MISSED_CALLS";
    public static final String ACTION_OPEN_CALL_LOGS = "com.android.phone.intent.OPEN_CALL_LOGS";
public ClearMissedCallsService() {
        super(ClearMissedCallsService.class.getSimpleName());
    }

    @Override
    public void onCreate() {
        super.onCreate();
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        // Clear the list of new missed calls.
        ContentValues values = new ContentValues();
        values.put(Calls.NEW, 0);
        StringBuilder where = new StringBuilder();
        where.append(Calls.NEW);
        where.append(" = 1 AND ");
        where.append(Calls.TYPE);
        where.append(" = ?");
        getContentResolver().update(Calls.CONTENT_URI, values, where.toString(),
                new String[]{ Integer.toString(Calls.MISSED_TYPE) });
        NativeCallLog.cancelMissedCallNotification();

        if (ACTION_OPEN_CALL_LOGS.equals(intent.getAction()))   {
            Intent intentOpenCallLogs = createOpenCallLogIntent();
            startActivity(intentOpenCallLogs);
        }

    }

    private static Intent createOpenCallLogIntent() {
        Intent intent = new Intent(Intent.ACTION_VIEW, null);
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intent.setType("vnd.android.cursor.dir/calls");
        return intent;
    }   

}    

您还需要在 AndroidManifest 中添加它

    <service
        android:exported="true"
        android:name="yourpackage.ClearMissedCallsService" >
        <intent-filter >
            <action android:name="com.android.phone.intent.CLEAR_MISSED_CALLS" />
        </intent-filter>
        <intent-filter >
            <action android:name="com.android.phone.intent.OPEN_CALL_LOGS" />
        </intent-filter>            
    </service>
