アンドロイド：フィルタはcostumのGridViewのアダプタで動作していない

Question

私はGridViewのとのEditTextを持っているシンプルなアプリの願い事をしようとしていると私はのEditTextで入力すると、それはここで入力

をコードするGridViewをフィルタリング

class CostumAdapter extends ArrayAdapter<Personne> implements Filterable{ 
    Costumfilter filter; 
    ArrayList <Personne> filterlist; 
    ArrayList <Personne> items; 
    public CostumAdapter(Context context, ArrayList <Personne> items) { 
     super(context,R.layout.costum_row,items); 
     this.filterlist=items; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     LayoutInflater inflater = LayoutInflater.from(getContext()); 
     View costumview = inflater.inflate(R.layout.costum_row, parent, false); 
     Personne imed=getItem(position); 
     TextView mytext = (TextView) costumview.findViewById(R.id.mytext1); 
     mytext.setText(imed.firstname); 
     mytext.setBackgroundColor(getRandomColor()); 
     return costumview; 
    } 

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

    public int getRandomColor(){ 
     Random rnd = new Random(); 
     return Color.argb(255, rnd.nextInt(256), rnd.nextInt(256), rnd.nextInt(256)); 
    } 

    class Costumfilter extends Filter{ 

     @Override 
     protected FilterResults performFiltering(CharSequence constraint) { 
      FilterResults results = new FilterResults(); 
      if(constraint != null && constraint.length()!=0){ 
       constraint = constraint.toString().toLowerCase(); 
       ArrayList<Personne> filters =new ArrayList<Personne>(); 
       for (int i=0; i <filterlist.size();i++){ 
        //probleme peut etre ici 
        if (filterlist.get(i).firstname.toLowerCase().contains(constraint.toString().toLowerCase())){ 
         Personne p =new Personne(filterlist.get(i).firstname,filterlist.get(i).lastname,filterlist.get(i).number,filterlist.get(i).mail); 
         filters.add(p); 
        } 
        if (filterlist.get(i).firstname.toLowerCase().startsWith(constraint.toString().toLowerCase())){ 
         Personne p =new Personne(filterlist.get(i).firstname,filterlist.get(i).lastname,filterlist.get(i).number,filterlist.get(i).mail); 
         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) { 
      items=(ArrayList<Personne>) results.values; 
      notifyDataSetChanged(); 
     } 
    } 
} 

これは私のメインクラス

public class MainActivity extends AppCompatActivity { 

ArrayList<Personne> items = new ArrayList<Personne>(); 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    ActionBar actionBar= getSupportActionBar(); 
    actionBar.hide(); 

    EditText textfilter =(EditText) findViewById(R.id.textfilter); 

    items.add(new Personne("kabouya","imed","0553164597","haha95@live.fr")); 
    items.add(new Personne("Tazir","oussama","0654613257","oussamaMail@live.fr")); 
    items.add(new Personne("kabouya","imed","0553164597","haha95@live.fr")); 
    items.add(new Personne("Tazir","oussama","0654613257","oussamaMail@live.fr")); 
    items.add(new Personne("kabouya","imed","0553164597","haha95@live.fr")); 
    items.add(new Personne("Tazir","oussama","0654613257","oussamaMail@live.fr")); 
    items.add(new Personne("kabouya","imed","0553164597","haha95@live.fr")); 
    items.add(new Personne("Tazir","oussama","0654613257","oussamaMail@live.fr")); 

    final CostumAdapter adapter = new CostumAdapter(MainActivity.this, items); 

    GridView mygrid=(GridView)findViewById(R.id.mygrid); 
    mygrid.setAdapter(adapter); 
    mygrid.setTextFilterEnabled(true); 
    textfilter.addTextChangedListener(new TextWatcher() { 
     @Override 
     public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) { 

     } 

     @Override 
     public void onTextChanged(CharSequence ss, int i, int i1, int i2) { 
      adapter.getFilter().filter(ss.toString()); 
     } 

     @Override 
     public void afterTextChanged(Editable editable) { 

     } 
    }); 

    mygrid.setOnItemClickListener(
      new AdapterView.OnItemClickListener(){ 

       @Override 
       public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) { 
        String someone=String.valueOf(adapterView.getItemAtPosition(i).toString()); 
        AlertDialog.Builder mBuilder = new AlertDialog.Builder(MainActivity.this); 
        View mView = getLayoutInflater().inflate(R.layout.custom_dialog, null); 
        TextView textnum =(TextView) mView.findViewById(R.id.textnum); 
        TextView textmail =(TextView) mView.findViewById(R.id.textmail); 
        TextView maintext =(TextView) mView.findViewById(R.id.maintext); 
        maintext.setText(items.get(i).firstname.toString()+" "+items.get(i).lastname.toString()); 
        textnum.setText(items.get(i).number.toString()); 
        textmail.setText(items.get(i).mail.toString()); 
        mBuilder.setView(mView); 
        AlertDialog dialog = mBuilder.create(); 
        dialog.show(); 
       } 
      } 
    ); 
} 

が、これは学校のプロジェクトであり、それはそうplsは私を助けて期日を持っている:)

私は問題はあなたがオーバーライドしていないということだと思いますしたがって、アダプタは変更されていないリストからデータを取得しています。

は、これらの変更

public CostumAdapter(Context context, ArrayList <Personne> items) { 
    super(context,R.layout.costum_row,items); 
    this.filterlist = items; 
    this.items = items; //initially you want to show all items 
} 

... 

@Override 
public Personne getItem(int position) { 
    return items.get(position); 
} 

で試してみて、おそらくあなたも getCount()

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