问题描述
这是我当前正在使用的代码
This is the code I'm currently using
String iosjiUrl = "http://modapps.com/NotoCoji.ttf";
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(iosjiUrl));
request.setDescription("Sscrition");
request.setTitle("Somle");
// in order for this if to run, you must use the android 3.2 to compile your app
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
request.allowScanningByMediaScanner();
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
}
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "NotoColorji.ttf");
// get download service and enqueue file
DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
manager.enqueue(request);
我无法找到一种方法来等待文件下载.
I'm not able to find a way for me to wait until the file is downloaded.
我还试图弄清楚如何进行ASync,但无论如何都无法弄清楚=/
I also tried figuring out how to go about doing ASync but couldn't figure that out either =/
再次感谢!
推荐答案
使用 BroadcastReceiver
检测下载何时完成:
Use a BroadcastReceiver
to detect when the download finishes:
public class DownloadBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) {
//Show a notification
}
}
}
并将其注册在您的清单中
and register it in your manifest:
<receiver android:name=".DownloadBroadcastReceiver">
<intent-filter>
<action android:name="android.intent.action.DOWNLOAD_COMPLETE"/>
</intent-filter>
</receiver>
