尽管在onProgressupdate中添加了项目，我仍然获得null arraylist ＆＃34; rev_arr＆＃34; 。 我在publishprogress方法中传递了String。 但它没有用。 为了方便起见，我没有在这里写入import语句。
这是我的代码 -

public String revmovieJsonStr;
public ArrayList<String > rev_arr = new ArrayList<String>();
public det_movFragment() {

This movie was awesome, and I think it can stand as a testimonial piece towards the capabilities that Christopher Pratt has. He nailed it. The graphics were awesome, the supporting cast did great and the t rex saved the child in me. 10\5 stars, four thumbs up, and I hope that star wars episode VII doesn't disappoint,
07-03 22:35:03.050 21092-21645/jindal5.mayank.popular_movies_14ce10032_gsc E/mayank﹕ Overall action packed movie... But there should be more puzzles in the climax... But I really love the movie.... Excellent...
