SearchView In ListView o niestandardowym adapterze

Question

Faceci Potrzebuję pomocy. Próbowałem implementować SearchView w moim projekcie. Ale mój projekt zawiera listę z niestandardowym adapterem do niej podłączonym. Miejsca ale wszystkie przykłady realizowane przy użyciu arrayadapter..Lets że mam klasę Employee i zawiera imię i wiek fields..How aby filtrować pracowników przy użyciu tylko ich nazwa ..

public class MainActivity extends Activity implements SearchView.OnQueryTextListener 
{ 
SearchView mSearchView; 
ListView mListView; 
//String mStrings[]= {"abc","def","efg","ghi","ijk","apple","agxhsdgc","abbbcc"}; 
ArrayList<Employee> emp_list=null; 
EmployeeAdapter emp_adapter=null; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     mSearchView=(SearchView) findViewById(R.id.searchView1); 
     mListView=(ListView) findViewById(R.id.listView1); 

     emp_list=new ArrayList<Employee>(); 
     emp_list.add(new Employee("ABC", 24)); 
     emp_list.add(new Employee("ACB", 24)); 
     emp_list.add(new Employee("BVF", 28)); 
     emp_list.add(new Employee("BRT", 28)); 
     emp_list.add(new Employee("ANM", 23)); 

     emp_adapter=new EmployeeAdapter(MainActivity.this, emp_list); 
     mListView.setAdapter(emp_adapter); 

//  mListView.setAdapter(new ArrayAdapter<String>(this, 
//    android.R.layout.simple_list_item_1, 
//    mStrings)); 
     mListView.setTextFilterEnabled(true); 
     setupSearchView(); 


    } 
    private void setupSearchView() 
    { 
      mSearchView.setIconifiedByDefault(false); 
      mSearchView.setOnQueryTextListener(this); 
      mSearchView.setSubmitButtonEnabled(true); 
      mSearchView.setQueryHint("Search Here"); 
     } 

     @Override 
     public boolean onQueryTextChange(String newText) 
     { 

      if (TextUtils.isEmpty(newText.toString())) { 
       mListView.clearTextFilter(); 
      } else { 
       mListView.setFilterText(newText.toString()); 
      } 
      return true; 
     } 

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


    } 

i to jest mój klasa adaptera, która rozszerza BaseAdapter ..

public class EmployeeAdapter extends BaseAdapter { 

    Context ctx; 
    ArrayList<Employee> emp_list; 
    LayoutInflater linf=null; 
    EmployeeHolder holder=null; 






    public EmployeeAdapter(Context ctx, ArrayList<Employee> emp_list) { 
     super(); 
     this.ctx = ctx; 
     this.emp_list = emp_list; 
     linf=(LayoutInflater) ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    } 

    public class EmployeeHolder 
    { 
     TextView name; 
     TextView age; 

    } 



    @Override 
    public int getCount() { 
     // TODO Auto-generated method stub 
     return emp_list.size(); 
    } 

    @Override 
    public Object getItem(int position) { 
     // TODO Auto-generated method stub 
     return emp_list.get(position); 
    } 

    @Override 
    public long getItemId(int position) { 
     // TODO Auto-generated method stub 
     return position; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     // TODO Auto-generated method stub 

     if(convertView==null) 
     { 
      convertView=linf.inflate(R.layout.row, parent, false); 
      holder=new EmployeeHolder(); 
      holder.name=(TextView) convertView.findViewById(R.id.name); 
      holder.age=(TextView) convertView.findViewById(R.id.age); 

      convertView.setTag(holder); 
     } 
     else 
     { 
      holder=(EmployeeHolder) convertView.getTag(); 
     } 

     Employee e=(Employee) getItem(position); 


     holder.name.setText(e.getName()); 
     holder.age.setText(String.valueOf(e.getAge())); 

     return convertView; 

    } 

} 

Th anks w Advance ..

Answer 2

Dobra odpowiedź jest tam, ale nadal istnieją pewne problemy (błędne stanowisko podczas onclick, serchview nakładka tekstowa), jak wspomniano w sekcji komentarza, więc możesz to również zrobić, postępując zgodnie z instrukcjami ing drogę

Reference, aby uzyskać więcej informacji: searchview listview android

Ja testowałem go i nie znaleźć żadnego problemu tak daleko, jeśli znajdziesz dowolny, proszę podać w sekcji komentarzy.

klasa Model: MovieNames.java

public class MovieNames { 
    private String movieName; 

    public MovieNames(String movieName) { 
     this.movieName = movieName; 
    } 

    public String getAnimalName() { 
     return this.movieName; 
    } 

} 

2: file listview_item.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:padding="10dp"> 


    <TextView 
     android:id="@+id/name" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" /> 

</RelativeLayout>
