WhatsApp似乎总是在后台运行时以高音量通知我,并且其中一位联系人(拥有自定义通知声音)出现。更改BroadcastReceiver for Notification中的输出音量以适应非流式首选项
我试图创建一个类似的效果。我想控制通知的音量。
我能找到的堆栈溢出的唯一例子是在这里this.
的不同之处在于:
- 我的背景是一个
BroadcastReceiver
- 我不是流媒体音乐,但使用基于通知声音在手机上可用的默认铃声列表(类似于WhatsApp)。
通知管理器基于getSystemService(Context.NOTIFICATION_SERVICE)
,因此通常用于流式传输的一些方法似乎不可用。
任何人都可以点亮一下。代码:
public class OnAlarmReceiver extends BroadcastReceiver {
private static final int NOTIFY_ME_ID=1337;
private static final String TAG = "OnAlarmReceiver";
@Override
public void onReceive(Context ctxt, Intent intent) {
Bundle bundle = intent.getExtras();
int itemId = bundle.getInt("itemId");
String itemTitle = bundle.getString("itemTitle");
int priority = bundle.getInt("priority");
long listId = bundle.getLong("listId");
String listTitle = bundle.getString("listTitle");
Toast.makeText(ctxt, "itemId: " + Integer.toString(itemId), Toast.LENGTH_LONG).show();
SharedPreferences prefs=PreferenceManager.getDefaultSharedPreferences(ctxt);
boolean useNotification=prefs.getBoolean("use_notification", true);
if (useNotification) {
NotificationManager mgr = (NotificationManager)ctxt.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification();
if (priority == 1) { // Display red icon
notification=new Notification(R.drawable.nuvola_apps_kwrite, itemTitle, System.currentTimeMillis());
} else { // Display blue icon
notification=new Notification(R.drawable.nuvola_apps_package_editors, itemTitle, System.currentTimeMillis());
}
Intent itemEditor = new Intent(ctxt, EditItem.class);
long lAlarmId = (long) (int) itemId;
itemEditor.putExtra(DbAdapter.KEY_ITEMS_ITEM_ID, lAlarmId);
itemEditor.putExtra("listId", listId);
itemEditor.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent i=PendingIntent.getActivity(ctxt, 0, itemEditor, PendingIntent.FLAG_UPDATE_CURRENT);
notification.setLatestEventInfo(ctxt, listTitle, itemTitle, i);
String notifyPreference = prefs.getString("notification_sound", "DEFAULT_RINGTONE_URI");
notification.sound = Uri.parse(notifyPreference);
if (priority == 1) {
notification.defaults |= Notification.DEFAULT_VIBRATE;
}
mgr.notify(itemId + NOTIFY_ME_ID, notification);
}
else {
Intent i=new Intent(ctxt, AlarmActivity.class);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
ctxt.startActivity(i);
}
}
}
