Viewpage的.setCurrentItem 导致UI线程的执行阻塞问题 广告轮播 数据加载后填充viewpagerAdapter

问题：

出现exception：Only the original thread that created a view hierarchy can touch its views.

执行U阻塞I的问题，现在想实现一个Viewpager自动轮播功能，并且是先去服务器端取得数据后再onPostExecute(String result) 

但是图片轮播的指示器的小圆点导致了一点加载问题。导致问题出现的地方是：

<span style="white-space:pre"></span>int maxIndex = Integer.MAX_VALUE / 2;        if (radioButtonID != null)        viewPager.setCurrentItem(maxIndex - (maxIndex % radioButtonID.length));//默认在中间，使用户看不到边界        else         viewPager.setCurrentItem(maxIndex);//默认在中间，使用户看不到边界

这一块不能再AsyncTask 的onPostExecute(String result) 方法中执行，必须执行在Activity的onCreate方法中

解决方法：

<span style="white-space:pre"></span>@Overrideprotected void onCreate(Bundle arg0) {super.onCreate(arg0);setContentView(R.layout.correcting_shopsgoods_detail);String per_data = null;String fdProdId,fdProdShortId;<span style="color:#ff6666;">initSlideViewPager();</span>isFirstCome = false;if (httpResult == null) {         per_data = getIntent().getExtras().getString("per_data");                if (per_data == null) return;                try {fdProdId = new JSONObject(per_data).getString("fdProdId");fdProdShortId = new JSONObject(per_data).getString("fdProdShortId");} catch (JSONException e) {return;}                String uris[] = new String[]{        Properties.SERVER_URL_TEST + "/api.ashx?method=Product.Detail&id=" + fdProdId + "&data=null&",        Properties.SERVER_URL_TEST + "/api.ashx?method=Store.Detail&id=" + fdProdShortId + "&data=null&"/*,        Properties.SERVER_URL_TEST + "/api.ashx?method=Store.Detail&id=" + fdProdShortId*/        };        String keys[] = new String[] {    "Product.Detail",        "Store.Detail1"/*,        "Store.Detail2"*/        };                mTaskList = new ArrayList<LoadDataAsyncTask>();          for (int i=0 ; i<keys.length ;i++) {        LoadDataAsyncTask task = new LoadDataAsyncTask(uris[i],keys[i]);mTaskList.add(task);   task.executeOnExecutor(FULL_TASK_EXECUTOR);}}}

<span style="white-space:pre"></span>/** * 这个模块不在oncreat方法中执行，会导致阻塞线程 * */private void initSlideViewPager() {viewPager = (SlideViewPager) findViewById(R.id.slide_viewpager);int maxIndex = Integer.MAX_VALUE / 2;        if (radioButtonID != null)        viewPager.setCurrentItem(maxIndex - (maxIndex % radioButtonID.length));//默认在中间，使用户看不到边界        else         viewPager.setCurrentItem(maxIndex);//默认在中间，使用户看不到边界}
