Question

我需要在同步活动运行时更改进度对话框的内容它显示“同步数据” 当它完成后，它将进行另一个后台活动，并且仍然显示相同的文本，我想要的是在进入其他后台任务时更改文本？

protected void onPreExecute() {
        mDialog = ProgressDialog.show(viewContext, "", "Synchronizing Data",
                true);

    };

    /*
     * (non-Javadoc)
     * 
     * @see android.os.AsyncTask#doInBackground(Params[])
     */
    @Override
    protected Boolean doInBackground(Void... arg0) {
        if (type.contains("ferry")) {
            return SynchronizeRepositoryFerry(false);

        } else {
            boolean value = SynchronizeRepositories(false, initialSync);
            mDialog.setTitle("Loading Images");//FROM HERE I WANT TO CHANGE DIALOG

            com.jumbybay.businessobjects.User user = new com.jumbybay.businessobjects.User();
            DatabaseHelper dbHelper = new DatabaseHelper(viewContext);
            IUserRepository repository = dbHelper.getUserRepository();
            List<com.jumbybay.businessobjects.User> imageList;
            try {
                int id;
                String url = "http://i.zdnet.com/blogs/3-29-androids.jpg";
                imageList = repository.Retrieve();
                for (int i = 0; i < imageList.size(); i++) {
                    user = imageList.get(i);
                    // url = user.getPicture();
                    id = user.getId();
                    fetchImage fetch = new fetchImage();
                    fetch.savesd(id, url);

                }
            } catch (SQLException e) {
                // TODO Auto-generated catch block// url = user.getPicture();
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            return value;

        }

    }

    protected void onProgressUpdate(Integer... progress) {
        mDialog.setTitle("lOADING IMAGES...");

    }
    /*
     * (non-Javadoc)
     * 
     * @see android.os.AsyncTask#onPostExecute(java.lang.Object)
     */
    @Override
    protected void onPostExecute(Boolean result) {
        this.syncComplete = result;
        mDialog.dismiss();
        Intent intent = new Intent();
        intent.setClass(viewContext, classType);
        viewContext.startActivity(intent);
    }

你试过像这样使用它吗

mDialog.setTitle("Loading Images");
 mDialog.show();

如何在运行时更改进度对话框的内容？
