Question

即使在切换标签后，我也试图让Recyclerview保持填充状态。我现在已经花了一段时间，尝试了几种方法，但都没有用。

MainActivity.java

 @Override
 protected void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Intent intent = getIntent();

    initTab
 }

 private void initTab(){

    //tab setup
    mTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);
    mTabHost.setup(MainActivity.this,getSupportFragmentManager(),android.R.id.tabcontent);

    ...

    mTabHost.addTab(mTabHost.newTabSpec("tab1").setIndicator(createTabView(icon_search, "search")),
            searchFragment.class, null);
    ...more tabs added...
    return;

片段

 private RecyclerView results;

 public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         final Bundle savedInstanceState){

    View v = inflater.inflate(R.layout.tab_search, container, false);
    results = (RecyclerView) v.findViewById(R.id.search_results);
    results.setHasFixedSize(true);

    LinearLayoutManager mLayoutManager = new LinearLayoutManager(getActivity());
    results.setLayoutManager(mLayoutManager);
    ScrollListener mScrollListener = new ScrollListener(mLayoutManager);
    results.setAdapter(searchResultsAdapter);
    results.addOnScrollListener(mScrollListener);

    return v;

我不能让mLayoutManager成为单身人士，否则我会从recyclerview那里得到错误

“LayoutManager已经附加到RecyclerView”

纵向模式已锁定且MainActivity未切换到其他活动

保持Recyclerview的标签更改
