Android搜索選項不起作用？

Question

自定義列表視圖中的android搜索功能不起作用。 RestListModel是我的模型名稱。

1. 這是我的上ManActivity代碼：

import android.support.v7.widget.SearchView; 

    private List<RestListModel> rdataList; 
    private ListView listView; 
    private CustomListAdapter adapter; 
    SearchView search; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.quick_list); 
     rdataList = new ArrayList<RestListModel>(); 
     listView = (ListView) findViewById(R.id.rrlist); 
     adapter = new CustomListAdapter(this, rdataList); 
     listView.setAdapter(adapter); 
     listView.setTextFilterEnabled(true); 
    } 
    // on create finished here 

    public boolean onCreateOptionsMenu(Menu menu) { 
     getMenuInflater().inflate(R.menu.menutosearch, menu); 

     final MenuItem myActionMenuItem = menu.findItem(R.id.action_search); 

     search = (SearchView) myActionMenuItem.getActionView(); 

     //*** setOnQueryTextListener *** 
     search.setOnQueryTextListener(new SearchView.OnQueryTextListener() { 

      @Override 
      public boolean onQueryTextSubmit(String query) { 
       // TODO Auto-generated method stub 

       return false; 
      } 

      @Override 
      public boolean onQueryTextChange(String newText) { 
       // TODO Auto-generated method stub 
       adapter.filter(newText); 
       return false; 
      } 
     }); 
     return true; 
    } 

適配器類：

public class CustomListAdapter extends BaseAdapter { 
     private Activity activity; 
     private LayoutInflater inflater; 
     private List<RestListModel> rItems=null; 
     private ArrayList<RestListModel> arraylist; 

     public CustomListAdapter(Activity activity, List<RestListModel> restItems) { 
      this.activity = activity; 
      this.rItems = restItems; 
      this.arraylist = new ArrayList<RestListModel>(); 
      this.arraylist.addAll(rItems); 
     } 

     /// I think something is wrong here 



     @Override 
     public int getCount() { 
      return rItems.size(); 

     } 

     @Override 
     public Object getItem(int location) { 
      return rItems.get(location); 
     } 

     @Override 
     public long getItemId(int position) { 
      return position; 
     } 



     @Override 
     public View getView(int position, View convertView, ViewGroup parent) { 

      convertView.setOnClickListener(new View.OnClickListener() { 

       public void onClick(View v) { 

       } 
      }); 

      return convertView; 
     } 

     // this is the actually filter Filter method. 
     public void filter(String charText) { 
      charText = charText.toLowerCase(Locale.getDefault()); 
      rItems.clear(); 
      if (charText.length() == 0) { 
       rItems.addAll(arraylist); 
      } else { 
       for (RestListModel wp : arraylist) { 
        if (wp.getName().toLowerCase(Locale.getDefault()) 
          .contains(charText)) { 
         rItems.add(wp); 
        } 
       } 
      } 
      notifyDataSetChanged(); 
     } 
    } 

Answer 1

變化CustomListAdapter這樣的：

public class CustomListAdapter extends BaseAdapter { 
    ... 

    public CustomListAdapter(Activity activity, List<Movie> movieItems) { 
     this.activity = activity; 
     this.movieItems= new ArrayList<>(movieItems); 
     this.arraylist = new ArrayList<>(movieItems); 
    } 

    ... 

    public void add(Movie movie) { 
     movieItems.add(movie); 
     arraylist.add(movie); 
    } 
} 

並添加這樣的：

public void onResponse(JSONArray response) { 
    ... 
     // adding movie to movies array 
     adapter.add(movie); 
    ... 
}

您正在僅與一個陣列比較與字符串。我需要添加具有三個不同字符串字段的模型。

public CustomListAdapter(Activity activity, List<RestListModel> restItems) { 
     this.activity = activity; 
     this.rItems = restItems; 
     this.arraylist = new ArrayList<RestListModel>(); 
     this.arraylist.addAll(rItems); 
    }
