搜索查看我的自定義適配器

Question

我試圖讓該適配器搜索視圖：

public class NotesAdapter extends BaseAdapter implements Filterable { 
/** 
* Wrapper para notas. Util para cambiar el fondo de los item seleccionados. 
*/ 
Paint paint = new Paint(); 
public static final String KEY_TITLE = "title"; 
public static final String KEY_BODY = "body"; 
public static final String KEY_CATID = "id"; 
private static final String DATABASE_TABLE = "notes_schema-v%s.sql"; 
private SQLiteDatabase mDb; 
private ArrayList<NotesAdapter.NoteViewWrapper> notesData; 
public Context context; 


public void notifyDataSetChanged() { 
    super.notifyDataSetChanged(); 
} 

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

public static class NoteViewWrapper { 

    private final Note note; 
    private boolean isSelected; 

    /** 
    * Contruye un nuevo NoteWrapper con la nota dada. 
    * 
    * @param note una nota. 
    */ 
    public NoteViewWrapper(Note note) { 
     this.note = note; 
    } 

    public Note getNote() { 
     return note; 
    } 

    public void setSelected(boolean isSelected) { 
     this.isSelected = isSelected; 
    } 
} 

private static final DateFormat DATETIME_FORMAT = DateFormat.getDateTimeInstance(DateFormat.MEDIUM, DateFormat.MEDIUM); 

private final List<NoteViewWrapper> data; 

/** 
* Constructor. 
* 
* @param data la lista de notas a usar como fuente de datos para este adaptador. 
*/ 
public NotesAdapter(List<NoteViewWrapper> data) { 
    this.data = data; 
} 

/** 
* @return cuantos datos hay en la lista de notas. 
*/ 
@Override 
public int getCount() { 
    return data.size(); 
} 

/** 
* @param position la posición de la nota que se quiere 
* @return la nota en la posición dada. 
*/ 
@Override 
public NoteViewWrapper getItem(int position) { 
    return data.get(position); 
} 

/** 
* @param position una posición 
* @return la misma posición dada 
*/ 
@Override 
public long getItemId(int position) { 
    return position; 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    ViewHolder holder; 
    if (convertView == null) { // inflar componente visual 
     convertView = LayoutInflater.from(parent.getContext()).inflate(R.layout.notes_row, parent, false); 
     //CardView cardsView = (CardView) convertView.findViewById(R.id.note_cardboard); 
     holder = new ViewHolder(convertView); 
     convertView.setTag(holder); 

    } else holder = (ViewHolder) convertView.getTag(); // ya existe, solo es reciclarlo 
    // Inicializa la vista con los datos de la nota 
    NoteViewWrapper noteViewWrapper = data.get(position); 
    holder.noteIdText.setText(String.valueOf(noteViewWrapper.note.getId())); 
    holder.noteTitleText.setText(noteViewWrapper.note.getTitle()); 
    // se la nota è più di 80 caratteri"..." 
    holder.noteContentText.setText(noteViewWrapper.note.getContent().length() >= 80 ? noteViewWrapper.note.getContent().substring(0, 80).concat("...") : noteViewWrapper.note.getContent()); 
    holder.noteDateText.setText(DATETIME_FORMAT.format(noteViewWrapper.note.getUpdatedAt())); 
    // Cambia il colore se la nota è cliccata 
    if (noteViewWrapper.isSelected) { 
     CardView cardsView = (CardView) convertView.findViewById(R.id.note_cardboard); 
     // sfondo grigio quando nota selezionata 
     cardsView.setCardBackgroundColor(Color.parseColor("#cacaca")); 
     //cardsView.setCardBackgroundColor(R.drawable.statelist_item_background); 
     //cardsView.setBackgroundResource(R.drawable.selected_note); 
     //holder.parent.setBackgroundColor(parent.getContext().getResources().getColor(R.color.selected_note)); 
     //LinearLayout.LayoutParams imageLayoutParams = new LinearLayout.LayoutParams(
     // LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT); 

    } else { 
     CardView cardsView = (CardView) convertView.findViewById(R.id.note_cardboard); 
     // sfondo bianco quando nota non selezionata 
     cardsView.setCardBackgroundColor(Color.WHITE); 
     //holder.parent.setBackgroundColor(parent.getContext().getResources().getColor(android.R.color.transparent)); 
    } 
    return convertView; 
} 


/** 
* Almacena componentes visuales para acceso rápido sin necesidad de buscarlos muy seguido. 
*/ 
private static class ViewHolder { 

    private TextView noteIdText; 
    private TextView noteTitleText; 
    private TextView noteContentText; 
    private TextView noteDateText; 

    private View parent; 

    /** 
    * Constructor. Encuentra todas los componentes visuales en el componente padre dado. 
    * 
    * @param parent un componente visual. 
    */ 
    private ViewHolder(View parent) { 
     this.parent = parent; 
     noteIdText = (TextView) parent.findViewById(R.id.note_id); 
     noteTitleText = (TextView) parent.findViewById(R.id.note_title); 
     noteContentText = (TextView) parent.findViewById(R.id.note_content); 
     noteDateText = (TextView) parent.findViewById(R.id.note_date); 
    } 
}} 

我很新，我不知道我該怎麼辦呢？所以我不能做到這一點。 任何人都可以幫助我嗎？

目前我有：

 searchView.setOnQueryTextListener(new MaterialSearchView.OnQueryTextListener() { 
     @Override 
     public boolean onQueryTextSubmit(String query) { 

      return false; 
     } 

     @Override 
     public boolean onQueryTextChange(String newText) { 

      return false; 
     } 
    }); 

    searchView.setOnSearchViewListener(new MaterialSearchView.SearchViewListener() { 
     @Override 
     public void onSearchViewShown() { 
      //Do some magic 
     } 

     @Override 
     public void onSearchViewClosed() { 
      //Do some magic 
     } 
    });

請添加像適配器類過濾器（字符串SEARCHTEXT）的公共方法;

private ArrayList<NotesAdapter.NoteViewWrapper> notesData; 

使這些ArrayList的

副本添加的所有項目從您的搜索查看onQueryTextChaged（複製ArrayList的

public void filter(String charItem) { 
    String searchItem = charItem.toLowerCase(Locale.getDefault); 
    notesData.remove(); 
    if(searchItem.length()<0){ 
    notesData.addAll(copyList); 
    } else{ 
    for(myItem item : copyList){ 
     if(item.name.contines(searchItem){ 
     notesData.add(item); 
     } 
    } 
    notifyDatasetChanged(); 
} 

調用這些函數）{}方法，並傳遞價值。
