展开搜索视图后出现意外空间

Question

一开始，SeachView 工作正常。在我切换到另一个片段后，然后返回然后单击搜索图标。工具栏已经垂直延伸，如下图

代码sn-p

@Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        inflater.inflate(R.menu.main, menu);

        // Associate searchable configuration with the SearchView
        SearchManager searchManager = (SearchManager) getActivity().getSystemService(Context.SEARCH_SERVICE);
        searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
        searchView.setSearchableInfo(searchManager.getSearchableInfo(getActivity().getComponentName()));
        searchView.setMaxWidth(Integer.MAX_VALUE);

        // listening to search query text change
        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {
                // filter recycler view when query submitted
                adapter.getFilter().filter(query);

                return false;
            }

            @Override
            public boolean onQueryTextChange(String query) {
                // filter recycler view when text is changed
                stationAdapter.getFilter().filter(query);
                return false;
            }
        });
        super.onCreateOptionsMenu(menu, inflater);
    }

Answer 1

android:paddingStart="-16dp" //根据需要设置dp

这对于棒棒糖后的设备来说已经足够了。
