如何登录Android的一个方法是什么？ [英] How to log a method in android?

问题描述

我想看到我的日志publishProgress（）调用下面的Asyncktask类。要查看是否它实际上是计算什么，而它的进展。因为它代表我有没有更新进度对话。

 公共字符串strAttachedFile =;
 公众持股量nTotalSize;
 公众持股量nUploadSize;
公共无效的send（）{        新Loadvid（）执行（）; //我们要求的AsyncTask
    }公共类Loadvid扩展的AsyncTask＆LT;字符串，整数，字符串＆GT; {            在preExecute保护无效（）{
            m_vwProgress.setMax（（INT）nTotalSize）;
            m_vwProgress.setMessage（上传，请稍候...）;
            m_vwProgress.setProgressStyle（ProgressDialog.STYLE_HORIZONTAL）;
                m_vwProgress.show（）;
            }
        }保护字符串doInBackground（字符串... PARAMS）{
            布尔m_bSuccess = TRUE;
            尝试
            {                MultipartEntity我=新MultipartEntity（）;                文件=的pFp新文件（strAttachedFile）;
                me.addPart（录像档案，新FileBody（PFP，视频/ 3GPP））;
                httppost.setEntity（箱）;
                //获取文件的总大小
                nTotalSize = pFp.length（）;                HTT presponse responsePOST = client.execute（httppost）;
                HttpEntity resEntity = responsePOST.getEntity（）;                为InputStream的InputStream = resEntity.getContent（）;
                StringBuilder的StringBuilder的=新的StringBuilder（）;
                字节的数据[] =新的字节[512];                而（（LEN = inputstream.read（数据））大于0）
                {
                    StringBuilder的结果= stringbuilder.append（新的String（数据，0，LEN））;
                     字符串s =将String.valueOf（结果）;
                     nUploadSize + = LEN;
                     publishProgress（（浮点）（nTotalSize / nUploadSize））;
                      字符串myString1 = Float.toString（（INT）nUploadSize）;
                     字符串myString2 = Float.toString（（INT）nTotalSize）;                     Log.i（上传SIZEEEEEEEE，myString1）;
                     Log.i（总SIZEEEEEEEE，myString2）;                }
                inputstream.close（）;            }赶上（例外五）{
                e.printStackTrace（）;
                m_bSuccess = FALSE;
            }            如果（m_bSuccess）{
                返回成功; //成功            }            返回null; //失败
        }保护无效onProgressUpdate（整数...值）{            如果（m_vwProgress！= NULL）{                m_vwProgress.setProgress（值[0]）;
                }
        }
        保护无效onPostExecute（字符串结果）{            super.onPostExecute（结果）;            如果（结果== NULL）{
                //失败
                如果（m_vwProgress！= NULL）
                    m_vwProgress.dismiss（）;                返回;
            }
            其他
            {
                //成功
                如果（m_vwProgress！= NULL）
                    m_vwProgress.dismiss（）;
            }
        }
 

解决方案

尝试匹配变量类型之间的 publishProgress ＆安培; onProgressUpdate 参数

 保护无效onProgressUpdate（浮动...值）
 

或

  publishProgress（（整数）（nTotalSize / nUploadSize）* 100）;
 

I am trying to see a log of my publishProgress() call in the Asyncktask class below. To see if it actually is calculating anything while it progresses. As it stands I have a progress dialogue that doesn't update.

 public String strAttachedFile = "";
 public float nTotalSize;
 public float nUploadSize;
public void Send(){

        new Loadvid().execute(); // our call for asynctask
    }

public class Loadvid extends AsyncTask <String,Integer,String>{

            protected void onPreExecute(){
            m_vwProgress.setMax((int)nTotalSize);
            m_vwProgress.setMessage("Uploading, Please wait...");
            m_vwProgress.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
                m_vwProgress.show();
            }
        }

protected String doInBackground(String... params) {


            boolean m_bSuccess = true; 
            try
            {

                MultipartEntity me = new MultipartEntity();

                File pFp = new File(strAttachedFile);
                me.addPart("videoFile", new FileBody(pFp, "video/3gpp"));
                httppost.setEntity(me);
                // get the total size of the file
                nTotalSize = pFp.length();

                HttpResponse responsePOST = client.execute(httppost);  
                HttpEntity resEntity = responsePOST.getEntity(); 

                InputStream inputstream = resEntity.getContent();
                StringBuilder stringbuilder = new StringBuilder();
                byte data [] = new byte[512]; 

                while ((len = inputstream.read(data))>0 )
                {
                    StringBuilder result= stringbuilder.append(new String(data, 0, len)); 
                     String s = String.valueOf(result);
                     nUploadSize += len;
                     publishProgress((float)(nTotalSize/nUploadSize));
                      String myString1 = Float.toString((int)nUploadSize);
                     String myString2 = Float.toString((int) nTotalSize);

                     Log.i("Upload SIZEEEEEEEE", myString1);
                     Log.i("Total SIZEEEEEEEE", myString2);

                }
                inputstream.close();

            }catch (Exception e) {
                e.printStackTrace();
                m_bSuccess = false; 
            }

            if(m_bSuccess){
                return "success";//Success

            }

            return null;//failed
        }

protected void onProgressUpdate(Integer... values) {

            if(m_vwProgress !=null){

                m_vwProgress.setProgress(values[0]);
                }
        }


        protected void onPostExecute(String result){

            super.onPostExecute(result);

            if(result==null){
                // failed
                if(m_vwProgress !=null)
                    m_vwProgress.dismiss();

                return;
            }
            else
            {
                //success
                if(m_vwProgress !=null)
                    m_vwProgress.dismiss();
            }
        }

解决方案

Try to match the variable types between publishProgress & onProgressUpdate parameters

protected void onProgressUpdate(float... values)

or

publishProgress((Integer)(nTotalSize/nUploadSize)*100);
