如何在动作条中添加搜索查看，并从列表视图

Question

我实现列表视图搜索，现在我想在列表视图

这里实现搜索功能是我的代码

@Override 
public boolean onQueryTextSubmit(String query) { 
    return false; 
} 

@Override 
public boolean onQueryTextChange(String newText) { 
    return true; 
} 

如何能够做到在搜索列表-view.i我没有得到如何实现其他功能也经过搜索和更新列表

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    MenuInflater inflater = getMenuInflater(); 
    // Inflate menu to add items to action bar if it is present. 
    inflater.inflate(R.menu.menu_product_detail, menu); 
    // Associate searchable configuration with the SearchView 
    SearchManager searchManager = 
      (SearchManager) getSystemService(Context.SEARCH_SERVICE); 
    SearchView searchView = 
      (SearchView) menu.findItem(R.id.menu_search).getActionView(); 
    searchView.setSearchableInfo(
      searchManager.getSearchableInfo(getComponentName())); 
    searchView.getQuery(); 
    Log.v("Abhijit", "" + searchManager.QUERY.toString()); 
    searchView.setOnQueryTextListener(this); 
    return true; 
} 

如何能够做到在列表view.i搜索我没有得到如何实现其他功能先进而精湛也是经过搜索和更新列表

Answer 1

使用此代码：

<item 
    android:id="@+id/action_search" 
    android:icon="@android:drawable/ic_menu_search" 
    app:showAsAction="always" 
    app:actionViewClass="android.support.v7.widget.SearchView" 
    android:title="Search"/> 

活动文件：

public boolean onCreateOptionsMenu(Menu menu) { 
    MenuInflater menuInflater = getMenuInflater(); 
    menuInflater.inflate(R.menu.dashboard, menu); 

    MenuItem searchItem = menu.findItem(R.id.action_search); 

    SearchManager searchManager = (SearchManager) MainActivity.this.getSystemService(Context.SEARCH_SERVICE); 

    SearchView searchView = null; 
    if (searchItem != null) { 
     searchView = (SearchView) searchItem.getActionView(); 
    } 
    if (searchView != null) { 
     searchView.setSearchableInfo(searchManager.getSearchableInfo(MainActivity.this.getComponentName())); 
    } 
     return super.onCreateOptionsMenu(menu); 
} 

清单文件：

<meta-data 
     android:name="android.app.default_searchable" 
     android:value="com.apkgetter.SearchResultsActivity" /> 

     <activity 
      android:name="com.apkgetter.SearchResultsActivity" 
      android:label="@string/app_name" 
      android:launchMode="singleTop" > 
      <intent-filter> 
       <action android:name="android.intent.action.SEARCH" /> 
      </intent-filter> 
      <intent-filter> 
       <action android:name="android.intent.action.VIEW" /> 
      </intent-filter> 

      <meta-data 
       android:name="android.app.searchable" 
       android:resource="@xml/searchable" /> 
     </activity> 

搜索XML文件：

<?xml version="1.0" encoding="utf-8"?> 
<searchable xmlns:android="http://schemas.android.com/apk/res/android" 
    android:hint="@string/search_hint" 
    android:label="@string/app_name" /> 

实现可过滤的listview适配器根据搜索到的数据过滤列表。

这是您在适配器如何筛选：

public class FavouritesAdapter extends RecyclerView.Adapter<FavouritesAdapter.MyViewHolder> implements Filterable { 

    private ItemFilter mFilter = new ItemFilter(); 
    private ArrayList<ProductDetail> listItems, filterList; 
    private Context context; 

    public class MyViewHolder extends RecyclerView.ViewHolder { 

     public TextView textView; 

     public MyViewHolder(View view) { 
      super(view); 
      textView  = (TextView) view.findViewById(R.id.textView); 
     } 
    } 

    public FavouritesAdapter(Context context, List<ProductDetail> listItems) { 
     this.context = context; 
     this.listItems = listItems; 
     this.filterList = new ArrayList<ProductDetail>(); 
     // we copy the original list to the filter list and use it for setting row values 
     this.filterList.addAll(this.listItems); 
    } 

    @Override 
    public FavouritesAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item_favourites, parent, false); 

     return new FavouritesAdapter.MyViewHolder(itemView); 
    } 

    @Override 
    public void onBindViewHolder(FavouritesAdapter.MyViewHolder holder, int position) { 
     holder.textView.setText(filterList.get(position)); 
    } 

    // Clean all elements of the recycler 
    public void clear() { 
     filterList.clear(); 
     notifyDataSetChanged(); 
    } 

    // Add a list of items 
    public void addAll(List<ProductDetail> list) { 
     filterList.addAll(list); 
     notifyDataSetChanged(); 
    } 

    @Override 
    public int getItemCount() { 
     return (null != filterList ? filterList.size() : 0); 
    } 

    @Override 
    public Filter getFilter() { 
     return mFilter; 
    } 

    private class ItemFilter extends Filter { 

     @Override 
     protected FilterResults performFiltering(CharSequence constraint) { 

      final Calendar calendar = Calendar.getInstance(); 

      String filterString = constraint.toString().toLowerCase(); 

      FilterResults results = new FilterResults(); 

      final List<ProductDetail> list = listItems; 

      int count = list.size(); 
      final ArrayList<ProductDetail> nlist = new ArrayList<ProductDetail>(count); 

      String filterableString ; 

      for (int i = 0; i < count; i++) { 
       filterableString = list.get(i).getYourObject; // get Your Object against whom you want to compare the list 
       if (filterableString.toLowerCase().contains(filterString)) { 
        nlist.add(listItems.get(i)); 
       } 
      } 

      results.values = nlist; 
      results.count = nlist.size(); 

      return results; 
     } 

     @SuppressWarnings("unchecked") 
     @Override 
     protected void publishResults(CharSequence constraint, Filter.FilterResults results) { 
      filterList = (ArrayList<ProductDetail>) results.values; 
      notifyDataSetChanged(); 
     } 

    } 

} 

在你的活动：

adapter.getFilter().filter(searchedEditText.getText().toString());
