Android上加载视图添加到AysncTask [英] Android add a loading view to an AysncTask

问题描述

您好，我有一个AsyncTask的那wroks唯一的问题是屏幕是空白的，直到一切都已经加载，所以我创建了一个loadingcell视图但我想知道如何把它显示加载视图，直到一切都被加载。

在这里我都试过，但它不能正常工作

 公共类PostTask扩展的AsyncTask＆LT;无效，字符串，布尔值＆GT; {        @覆盖
        保护布尔doInBackground（虚空...... PARAMS）{
            布尔结果= FALSE;
            loadFixtures（）;
            publishProgress（进步）;
            loadResultsFeed（）;
            publishProgress（进步）;
            loadNewsFeed（）;
            publishProgress（进步）;
            返回结果;
        }
        保护无效onProgressUpdate（字符串...进度）{
            StringBuilder的海峡=新的StringBuilder（）;
                的for（int i = 1; I＆LT; progress.length;我++）{
                    str.append（进度[I] +）;                  loadingView = LayoutInflater.from（getBaseContext（））。膨胀（R.layout.loadingcell，
                         空值）;                }
        }            @覆盖
        保护无效onPostExecute（布尔结果）{
            super.onPostExecute（结果）;
            Log.v（BGThread，开始FILLIN数据）;
             FillData（）;
        }
    }
 

解决方案

 保护无效onPostExecute（布尔结果）{
        super.onPostExecute（结果）;
        Log.v（BGThread，开始FILLIN数据）;
         FillData（）;
     //隐藏你的看法此处＆lt; ---------
     //为前：
      progressbar.setVisibility（View.GONE）; ＆LT; ---------    }
 

Hi there i have an Asynctask that wroks only problem is the screen is blank until everything has loaded so i have created a loadingcell view but i'm wanting to know how to have it show the loading view until everything is loaded.

here what i have tried but it doesn't work

public class PostTask extends AsyncTask<Void, String, Boolean> {



        @Override
        protected Boolean doInBackground(Void... params) {
            boolean result = false;


            loadFixtures();
            publishProgress("progress");
            loadResultsFeed();
            publishProgress("progress");
            loadNewsFeed();
            publishProgress("progress");
            return result;
        }


        protected void onProgressUpdate(String... progress) {
            StringBuilder str = new StringBuilder();
                for (int i = 1; i < progress.length; i++) {
                    str.append(progress[i] + " ");

                  loadingView = LayoutInflater.from(getBaseContext()).inflate(R.layout.loadingcell,
                         null);

                }
        }

            @Override
        protected void onPostExecute(Boolean result) {
            super.onPostExecute(result);
            Log.v("BGThread", "begin fillin data");
             FillData();
        }
    }

解决方案

protected void onPostExecute(Boolean result) {
        super.onPostExecute(result);
        Log.v("BGThread", "begin fillin data");
         FillData();
     // hide your view here                                <---------
     // for ex:    
      progressbar.setVisibility(View.GONE);                <---------

    }
