Question

我可以打开SearchView，但无论我尝试什么，我都无法恢复搜索内容......

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{
    inflater.inflate(R.menu.menu_phone_contacts_list, menu);
    MenuItem searchItem = menu.findItem(R.id.action_search);
    final SearchView searchView = (SearchView) searchItem.getActionView();
    searchView.setOnQueryTextListener(this);

    if (DataManager.get().getLastContactFilter() != null)
    {
        MenuItemCompat.expandActionView(searchItem);

       // Variant 1 - does not work:
       searchView.setQuery(DataManager.get().getLastContactFilter(), false);

       // Variant 2 - does not work either:
       searchView.post(new Runnable() {
           @Override
           public void run() {
               searchView.setQuery(DataManager.get().getLastContactFilter(), false);
           }
       });
    }

变体3正在恢复以下功能中的内容：

  @Override
public void onPrepareOptionsMenu (Menu menu)
{
    super.onPrepareOptionsMenu(menu);

    if (DataManager.get().getLastContactFilter() != null)
    {
        SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
        searchView.setQuery(DataManager.get().getLastContactFilter(), false);
    }
}

但没有变体确实有用......

Answer 1

使用静态MenuItemCompat方法获取SearchView

MenuItem searchItem = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
searchView.setQuery("myQueryText", false);

并检查xml项目菜单，它需要＆＃34; app＆＃34;前缀（与平台无关）

app:actionViewClass="android.support.v7.widget.SearchView"
