我想我的應用程序,可以同時下載多個文件,並顯示在通知區域下載每個文件的過程 我該怎麼做?現在我只能顯示1個進程欄當我下載文件。 這裏提交notification_progress_layout.xmlandroid通知擴大視圖與多個進程欄
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="5dp">
<ImageView android:id="@+id/status_icon"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_alignParentLeft="true"
android:layout_marginRight="10dp"
android:src="@drawable/icon_download1"/>
<RelativeLayout android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_toRightOf="@id/status_icon">
<TextView android:id="@+id/status_text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
/>
<ProgressBar android:id="@+id/status_progress"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@id/status_text"
android:indeterminate="false"
android:indeterminateOnly="false"
style="?android:attr/progressBarStyleHorizontal" />
</RelativeLayout>
和nofitication文件
Intent notificationIntent = new Intent();
PendingIntent contentIntent = PendingIntent.getActivity(activity, 0, notificationIntent, 0);
notificationManager = (NotificationManager) activity.getSystemService(Context.NOTIFICATION_SERVICE);
notification = new Notification(R.drawable.icon_download1, "Downloading...", System.currentTimeMillis());
contentView = new RemoteViews(activity.getPackageName(), R.layout.notification_progress_layout);
contentView.setProgressBar(R.id.status_progress, 100, 0, false);
contentView.setTextViewText(R.id.status_text,"Downloading...");
notification.flags = notification.flags| Notification.FLAG_ONGOING_EVENT;
notification.contentView = contentView;
notification.contentIntent = contentIntent;
notificationManager.notify(NOTIFICATION_ID,notification);
我認爲它只適用於4.1中引入的消耗性通知。搜索BigContentView以獲取有關如何執行此操作的示例。 – Teovald
