问题描述

使用下载管理器下载文件在Android中，我需要为everydownloaded文件运行一个命令，但是我的接收器不工作，如果我把10files下载，它只是返回最后下载的文件标题IM，为什么呢？

 广播接收器接收器=新的广播接收器（）{
    @覆盖
    公共无效的onReceive（上下文的背景下，意图意图）{
        字符串行动= intent.getAction（）;
        如果（DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals（动作））{            长downloadId = intent.getLongExtra（
                    DownloadManager.EXTRA_DOWNLOAD_ID，0）;
            查询查询=新的Query（）;
            query.setFilterById（排队）;
            光标C = dmAndroid.query（查询）;
            如果（c.moveToFirst（））{
                //Log.d(\"ainfo，c.getString（c.getColumnIndex（标题）））; - ＆GT; STIL返回刚刚过去的
                / *
                INT I = 0;
                 而（ⅰ＆下; c.getColumnCount（））{Log.d（AINFO，
                 c.getColumnName（I）+ - + I + - + c.getString（ⅰ））;
                 我++; }
                * /
                INT参数：columnIndex = C
                        .getColumnIndex（DownloadManager.COLUMN_STATUS）;                如果（DownloadManager.STATUS_SUCCESSFUL == c审核
                        .getInt（参数：columnIndex））{//如果我把这里仍然只返回上次下载
                    字符串uriString中= C
                            .getString（三
                                    .getColumnIndex（DownloadManager.COLUMN_LOCAL_URI））;                    如果（downloadId == c.getInt（0））{
                        Log.d（AINFO，c.getString（c.getColumnIndex（标题）））; //一样，刚刚过去的下载文件标题
                    }
                }
            }        }
    }
};

你有没有在Android清单文件注册您的广播接收器。

im using DownloadManager to download files in android, and i need to run a command for everydownloaded file, but my receiver is not working, if i put 10files to download, it just return the LAST downloaded file title, why?

BroadcastReceiver receiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) {

            long downloadId = intent.getLongExtra(
                    DownloadManager.EXTRA_DOWNLOAD_ID, 0);
            Query query = new Query();
            query.setFilterById(enqueue);
            Cursor c = dmAndroid.query(query);
            if (c.moveToFirst()) {
                //Log.d("ainfo", c.getString(c.getColumnIndex("title"))); -> stil return just the last
                /*
                int i = 0;
                 while(i < c.getColumnCount()) { Log.d("ainfo",
                 c.getColumnName(i) + "-" + i + "-" + c.getString(i));
                 i++; }
                */
                int columnIndex = c
                        .getColumnIndex(DownloadManager.COLUMN_STATUS);

                if (DownloadManager.STATUS_SUCCESSFUL == c
                        .getInt(columnIndex)) {

// if i put here still return the last download only
                    String uriString = c
                            .getString(c
                                    .getColumnIndex(DownloadManager.COLUMN_LOCAL_URI));

                    if (downloadId == c.getInt(0)) {
                        Log.d("ainfo", c.getString(c.getColumnIndex("title"))); //same, just the last download file title


                    }
                }


            }

        }
    }
};
