监听下载完成：
要想在下载完成后收到一个通知，需要注册一个Receiver来接收ACTION_DOWLOAD_COMPLETE广播。它将包含一个EXTRA_DOWNLOAD_ID extra，其中包含了已经完成下载的引用ID：
public void funclick(View view){
String serviceString = Context.DOWNLOAD_SERVICE;
DownloadManager downloadManager;
downloadManager = (DownloadManager)getSystemService(serviceString);
Uri uri = Uri.parse("http://img00.hc360.com/it/201206/201206121034589404.jpg");
DownloadManager.Request request = new Request(uri);
request.setAllowedNetworkTypes(Request.NETWORK_WIFI);
downloadManager.getRecommendedMaxBytesOverMobile(getApplicationContext());
final long myreference = downloadManager.enqueue(request);
IntentFilter filter = new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE );
BroadcastReceiver receiver = new BroadcastReceiver(){
@Override
public void onReceive(Context context, Intent intent) {
long reference = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID,-1);
if(reference == myreference){
//对下载的文件进行一些操作
}
}
};
registerReceiver(receiver, filter);
}
监听点击下载通知栏：
IntentFilter filter = new IntentFilter(DownloadManager.ACTION_NOTIFICATION_CLICKED);
BroadcastReceiver receiver = new BroadcastReceiver(){
@Override
public void onReceive(Context context, Intent intent) {
String extraID = DownloadManager.EXTRA_NOTIFICATION_CLICK_DOWNLOAD_IDS;
long[] references = intent.getLongArrayExtra(extraID);
for(long reference : references){
if(reference == myreference){
//对下载的文件进行一些操作
}
}
}
};
registerReceiver(receiver, filter);
