Question

我想要我的应用程序可以同时下载多个文件并显示在通知区域中下载每个文件的过程我怎么能这样做？现在我下载文件时只能显示1个进程条。这里有文件notification_progress_layout.xml

<?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);

Answer 1

这样做：

创建一个内置LinearLayout的默认XML。
创建另一个内部带有ProgressBar的布局。
使用以下代码。

代码：

contentView = new RemoteViews(activity.getPackageName(), R.layout.notification_progress_main);
for (i=0; i<downloads.length;i++){
   contentView2 = new RemoteViews(activity.getPackageName(), R.layout.notification_progress_layout);
   contentView2.setProgressBar(R.id.status_progress, 100, 0, false); 
   contentView.addView(R.layout.linearid, contentView2);

}
notification.contentView = contentView;
notificationManager.notify(NOTIFICATION_ID,notification);

使用每次下载的正确值更改progressBar值。
