问题描述

我开发一个在操作栏中搜索查看一个应用程序，我有问题，当我做到完美搜索的过滤器，但是当我preSS后退按钮它仍然呈现过滤数据，所以我的问题是什么是事件操作栏搜索视图后退按钮？

I have Develop an application that have search view in action bar and i got issue when i am do search its filter perfectly but when i am press back button its still showing filter data so my question is what is event of back button of Action Bar Search view.?

的搜索查看我的code是

My Code of Search View is

SearchView searchView = (SearchView) MenuItemCompat.getActionView(menu.findItem(Menus.SEARCH));
    searchView.setQueryHint(this.getString(R.string.search));
    editSearch = (EditText) searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text);
    editSearch.setHintTextColor(getResources().getColor(R.color.white));
    searchView.setOnQueryTextListener(OnQuerySearchView);


 private OnQueryTextListener OnQuerySearchView = new OnQueryTextListener() {

    @Override
    public boolean onQueryTextSubmit(String newText) {
        if (TextUtils.isEmpty(newText)) {
            listAllContact.clearTextFilter();
        } else {
            listAllContact.setFilterText(newText.toString());
        }
        return true;
    }

    @Override
    public boolean onQueryTextChange(String newText) {
        String text = editSearch.getText().toString()
                .toLowerCase(Locale.getDefault());
        adapter.filter(text);
        return true;
    }

};

在适配器过滤法

public void filter(String charText) {
    charText = charText.toLowerCase(Locale.getDefault());
    propertyList.clear();

    if (charText.length() == 0) {
       propertyList.addAll(arrayList);
    notifyDataSetChanged();

    } else {
        for (ContactProperty p : arrayList) {
            if (p.getFriendName().toLowerCase(Locale.getDefault())
                    .contains(charText)) {
                propertyList.add(p);
            }
        }
        notifyDataSetChanged();

    }

推荐答案

您可以将此作为添加监听器

You can add listener for this as :

MenuItem searchMenuItem = menu.findItem(R.id.menu_search);
    searchMenuItem.setOnActionExpandListener(new MenuItem.OnActionExpandListener() {

        @Override
        public boolean onMenuItemActionExpand(MenuItem item) {
            // Do whatever you need
            return true; // KEEP IT TO TRUE OR IT DOESN'T OPEN !!
        }

        @Override
        public boolean onMenuItemActionCollapse(MenuItem item) {
            // Do whatever you need
            return true; // OR FALSE IF YOU DIDN'T WANT IT TO CLOSE!
        }
    });
