我正在使用DownloadManager
从我的Android应用程序从Web服务器下载文件到设备外部存储。我需要在完成此下载时启动另一个功能。我的文件下载代码如下:
String url = "http://192.168.1.105/download/file.ext";
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "files.ext");
DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
final long downloadId = manager.enqueue(request);
请建议如何获得onDownloadComplete

您可以将ACTION_DOWNLOAD_COMPLETE与BroadcastReceiver
一起使用public class DonwloadCompleteReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// get complete download id
long completeDownloadId = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, -1);
// to do here
}
}

我在DownloadManager.ACTION_DOWNLOAD_COMPLETE broadcast receiver receiving same download id more than once with different download statuses in Android发现了我的回答 我的代码是这样的:
private boolean downloadComplete(long downloadId){
DownloadManager dMgr = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
Cursor c= dMgr.query(new DownloadManager.Query().setFilterById(downloadId));
if(c.moveToFirst()){
int status = c.getInt(c.getColumnIndex(DownloadManager.COLUMN_STATUS));
if(status == DownloadManager.STATUS_SUCCESSFUL){
return true; //Download completed, celebrate
}else{
int reason = c.getInt(c.getColumnIndex(DownloadManager.COLUMN_REASON));
Log.d(TAG, "Download not correct, status [" + status + "] reason [" + reason + "]");
return false;
}
}
return false;
}

public class myAwesomeClass extends Activity{
public void onButtonClicked(View view){
if (dummy has row){
//do something
//and proceed to next row
}
