Answer 1

Eine XML Datei in res/menu/menu.xml:

<?xml version="1.0" encoding="utf-8"?> 
<menu xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto"> 
    <item 
     app:actionViewClass="android.support.v7.widget.SearchView" 
     android:id="@+id/search_menu" 
     android:title="" 
     android:icon="@mipmap/ic_search" 
     app:showAsAction="ifRoom|collapseActionView"/> 
</menu> 

Dann fügen Sie diese zu Ihrem Fragment

onCreate

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setHasOptionsMenu(true); 
} 

onCreateOptionsMenu

@Override 
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) { 
    inflater.inflate(R.menu.menu, menu); 
    MenuItem item = menu.findItem(R.id.search_menu); 
    SearchView searchView = (SearchView) MenuItemCompat.getActionView(item); 
    searchView.setQueryHint("hit text"); 
    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() { 
     @Override 
     public boolean onQueryTextChange(String newText) { 
      //define your adapter as global 
      adapter.getFilter().filter(newText); 

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

    super.onCreateOptionsMenu(menu, inflater); 
} 

Konvertieren Sie Ihre String-Array Arraylist, lassen Sie dann Ihre Adapter Geräte Filterable

class MyAdapter extends BaseAdapter implements Filterable{} 

Wenn Sie wissen nicht, wie in diesem example

Und schließlich überschreiben aussehen zu konvertieren getFilter in Adapter basierend auf, was Sie brauchen:

@Override 
public Filter getFilter() { 
Filter filter = new Filter() { 
    @Override 
    protected void publishResults(CharSequence constraint, FilterResults results) { 
    } 
    @Override 
    protected FilterResults performFiltering(CharSequence constraint) { 
     FilterResults results = new FilterResults(); 
     // Implement your logic here 
     return results; 
    } 

    }; 
    return filter; 
}
