我有一个 Asynctask，它应该使用 onProgressUpdate 将 Rowlayout 添加到 Scrollingview 内的 Tablelayout。在 Asynctask 工作期间，行被添加到 tablelayout 并且一切都很好。但是在 Asynctask 工作期间，尽管我看到添加的行，但我无法滚动 Scrollview。如果 Asynctask 完成，我只能滚动。

异步任务

  private class DownloadWebPageTask extends AsyncTask<Integer, String, String> 
  {
    @Override
    protected String doInBackground(Integer... params) {        
        Integer k = 0;
        for(int i = 0; i < 100; i++)
        {
            if(i == 80)
            {
                System.out.println("Debug Breakpoint");
            }
            publishProgress("hey");
        }       
        return k.toString();
    }
    @Override
    protected void onProgressUpdate(String... ProduktListe)
    {
        writeSomeThing();
    }
    @Override
    protected void onPostExecute(String result) 
    {             

    }   
  }

创建行

  public void writeSomeThing() 
  {     
            //make here breakpoint
            MainActivity context = this;


            TableLayout searchBody = (TableLayout) context.findViewById(R.id.tableLayout);

            LayoutInflater inflater = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);

            TableRow rowView = (TableRow)inflater.inflate(R.layout.reintuding, null);

            searchBody.addView(rowView);    
  }
