Android androidx.SearchView 不工作

Question

我在我的项目中的 MaterialToolBar 中实现了 SearchView。 除了最后一步，一切正常。 当我在搜索栏中输入任何内容并单击键盘查找按钮时，它不会显示任何内容。 请帮忙。

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.cart_search_menu, menu);

        SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        SearchView searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();
        searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
        searchView.setMaxWidth(Integer.MAX_VALUE);
        
        SearchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {
                
                // your code
                
                return false;
            }

            @Override
            public boolean onQueryTextChange(String query) {
                // your code
                return false;
            }
        });
        return true;
    }

检查这个截图试试这个

在菜单文件中：

<item
    android:id="@+id/actionTenantSearch"
    android:icon="@drawable/ic_search"
    android:title="@string/search"
    app:showAsAction="ifRoom|collapseActionView"
    app:actionViewClass="androidx.appcompat.widget.SearchView"
    />

在 kotlin 文件中：

  private var searchItem : MenuItem? = null
override fun onCreateOptionsMenu(menu: Menu, inflater: MenuInflater) {
    inflater.inflate(R.menu.search_tenant_menu, menu)
    searchItem = menu.findItem(R.id.actionTenantSearch)

    val searchView = searchItem?.actionView as SearchView
    searchView.setOnQueryTextListener(object :
        SearchView.OnQueryTextListener {
        override fun onQueryTextSubmit(s: String): Boolean {
            CommonUtils.showToast(requireContext(), s)
            searchView.clearFocus()
            return true
        }

        override fun onQueryTextChange(s: String): Boolean {

            return true
        }
    })
    super.onCreateOptionsMenu(menu, inflater)
}

@vaibhav 您是否在列表视图或回收站视图中实现了可过滤的 class。 之后在您的搜索查询中调用该可过滤方法。 你会得到适当的 reault 像这样

公共 class 适配器名称扩展 RecyclerView.Adapter<ContactAdapter.MyViewHolder> 实现可过滤 {

}

CustomFilter 过滤器；

@Override
public Filter getFilter() {
    if (filter == null) {
        filter = new CustomFilter();
    }
    return filter;
}

class CustomFilter extends Filter {
    @Override
    protected FilterResults performFiltering(CharSequence constraint) {
        // TODO Auto-generated method stub
        FilterResults results = new FilterResults();
        if (constraint != null && constraint.length() > 0) {
            //CONSTARINT TO UPPER
            constraint = constraint.toString().toUpperCase();
            ArrayList<AllInOnetItem> filters = new ArrayList<AllInOnetItem>();
            //get specific items
            for (int i = 0; i < filterList.size(); i++) {
                if (filterList.get(i).getName().toUpperCase().contains(constraint)) {
                    AllInOnetItem p = new AllInOnetItem(filterList.get(i).getName(), filterList.get(i).getNumber(),filterList.get(i).getEmail());
                    filters.add(p);
                }
            }
            results.count = filters.size();
            results.values = filters;
        } else {
            results.count = filterList.size();
            results.values = filterList;
        }
        return results;
    }

    @Override
    protected void publishResults(CharSequence constraint, FilterResults results) {
        // TODO Auto-generated method stub
        allInOnetItems = (ArrayList<AllInOnetItem>) results.values;
        notifyDataSetChanged();
    }
}

之后我更改了代码行的顺序，它运行良好。

前：

super.onCreate(savedInstanceState);
Toolbar toolbar = findViewById(R.id.category1_toolbar);
setSupportActionBar(toolbar);
setContentView(R.layout.activity_product_list);

后：

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_product_list);
Toolbar toolbar = findViewById(R.id.category1_toolbar);
setSupportActionBar(toolbar);
