Android fragment + FragmentTabHost + viewpager switchover status not saved

Android fragment + FragmentTabHost + viewpager switchover status not saved

 

@ Author dujinyang

It is rare to have time to write a blog.

Although fragment is easy to use, I still think it has advantages and disadvantages.

Switching status is often said on the Internet, which has many problems,

There are many solutions.

The first common situation:

if(rootView == null)rootView = inflater.inflate(R.layout.fragment_home, container,false);ViewGroup parent = (ViewGroup) rootView.getParent(); if (parent != null)      parent.removeView(rootView); initView(rootView);  return rootView;

 

 

The second is LISTVIEW:

Similarly, in the listview adapter,

 

@ Overridepublic View getView (int position, View convertView, ViewGroup parent) {View view = convertView; if (view = null) {view = new TextView (getActivity (). getApplicationContext ();} (TextView) view ). setText (this is the + position + test data); (TextView) view ). setTextSize (20); return view ;}

 

 

 

The third estimate is that few people encounter:

After one afternoon, you need to add ViewPager + Tabhost + animation in the first option of the TAB due to the demand relationship,

In fact, it took a long time to find that the animation layer was not saved, but it was impossible to save the location because it was an image,

It has been tested for a long time.

OnPageSelected rewritten in OnPageChangeListener. In the switch selector, the animation layer output comes with arg0,

Add one more option for each tab, Which is saved as a location and cannot be located in the outer record because of a BUG. The original position is calculated based on the position of each tab, which solves the location information generated during sliding.

I hope it will be useful to you. If you have other problems, leave a message or add me Q.
