当我点击gridview上的项目时，它应该显示我即将推出的游戏列表，但它会给我null listview ...为什么？
这是代码：
private View.OnClickListener getGamesByDate(final String[] date, final ListView luListView) {
return new View.OnClickListener() {
@Override
public void onClick(View v) {
// send post request to get game by date and Plyid
Log.e("DATE", date[0]+"-"+date[1]+"-"+date[2]);
String dt = date[0] + "-" + date[1] + "-" + date[2];
// 2016-02-18 the date in the hashmap of games
GameEvent gm = ViewUpcomingGmsAsyncTask.hashUpcoming.get(dt);
// ViewUpcomingGmsAsyncTask playerEvents = new ViewUpcomingGmsAsyncTask(new ProgressDialog(mContext), mContext,gridview );
Log.e("tabs",""+luListView);
ProgressDialog progress= new ProgressDialog(mContext);
/* GamesAdapter upcomingAdapter = new GamesAdapter(arrayLists,mContex,lvupcoming,3);
lvupcoming.setAdapter(upcomingAdapter);*/
new ViewUpcomingGmsAsyncTask(progress,mContext,luListView).execute();
// Log.e("tabs",""+luListView);
if (gm!=null){
Bundle mBundle = new Bundle();
mBundle.putSerializable("gm",gm);
GameDetailsFragment GameDetails=GameDetailsFragment.newInstance();
GameDetails.setArguments(mBundle);
mContext.getSupportFragmentManager().beginTransaction().replace(R.id.container,
GameDetails,"gmDetails").addToBackStack("gmDetails").commit();
}
}
};}

我想用gameevent的日期显示listview .... 任何人都可以找到这个问题的解决方案吗？
