我試圖在我的下載管理器中實(shí)現(xiàn)暫停/恢復(fù)，我搜索網(wǎng)頁(yè)并閱讀幾篇文章，并根據(jù)他們修改代碼，但恢復(fù)似乎無(wú)法正常工作，任何想法？

if (!downloadPath.exists())

downloadPath.mkdirs();

if (outputFileCache.exists())

{

downloadedSize = outputFileCache.length();

connection.setAllowUserInteraction(true);

connection.setRequestProperty("Range", "bytes=" + downloadedSize + "-");

connection.setConnectTimeout(14000);

connection.connect();

input = new BufferedInputStream(connection.getInputStream());

output = new FileOutputStream(outputFileCache, true);

input.skip(downloadedSize); //Skip downloaded size

}

else

{

connection.setConnectTimeout(14000);

connection.connect();

input = new BufferedInputStream(url.openStream());

output = new FileOutputStream(outputFileCache);

}

fileLength = connection.getContentLength();

byte data[] = new byte[1024];

int count = 0;

int __progress = 0;

long total = downloadedSize;

while ((count = input.read(data)) != -1 && !this.isInterrupted())

{

total += count;

output.write(data, 0, count);

__progress = (int) (total * 100 / fileLength);

}

output.flush();

output.close();

input.close();
