我搜索了很多内容,但我找不到关于两个暂停和恢复按钮的解决方案。
我使用的是 this code this
但我不知道如何实现暂停和恢复功能,并设置我的暂停和恢复按钮onclick事件:

pausebtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            stopdownload(); AND resumedownload(); <------
        }
    });


提前谢谢。

停止下载电话

downloadTask.cancel(false);

要支持恢复下载,您可以使用Resume http file download in java中的代码:

HttpURLConnection connection = (HttpURLConnection) url.openConnection();
if(ISSUE_DOWNLOAD_STATUS.intValue()==ECMConstant.ECM_DOWNLOADING){
    File file=new File(DESTINATION_PATH);
    if(file.exists()){
         downloaded = (int) file.length();
         connection.setRequestProperty("Range", "bytes="+(file.length())+"-");
    }
}else{
    connection.setRequestProperty("Range", "bytes=" + downloaded + "-");
}
connection.setDoInput(true);
connection.setDoOutput(true);
progressBar.setMax(connection.getContentLength());
in = new BufferedInputStream(connection.getInputStream());
fos=(downloaded==0)? new FileOutputStream(DESTINATION_PATH): new FileOutputStream(DESTINATION_PATH,true);
bout = new BufferedOutputStream(fos, 1024);
byte[] data = new byte[1024];
int x = 0;
while ((x = in.read(data, 0, 1024)) >= 0) {
    bout.write(data, 0, x);
     downloaded += x;
     progressBar.setProgress(downloaded);
}
