Custom Listview Adaptateur avec filtre Android

Question

Veuillez essayer d'implémenter un filtre sur ma listview. Mais chaque fois que le texte change, la liste disparaît.Veuillez m'aider Voici mes codes. La classe d'adaptateur.

package com.talagbe.schymn; 

import java.util.ArrayList; 

import android.content.Context; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.ArrayAdapter; 
import android.widget.TextView; 

public class HymnsAdapter extends ArrayAdapter<Hymns> { 
ArrayList<Hymns> hymnarray; 
Context context; 
LayoutInflater inflater; 
int Resource; 


public HymnsAdapter(Context context, int resource, ArrayList<Hymns> objects) { 
    super(context, resource, objects); 
    // TODO Auto-generated constructor stub 

    hymnarray=objects; 
    Resource= resource; 
    this.context=context; 
    inflater= (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE); 
} 


@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    // TODO Auto-generated method stub 
    ViewHolder holder; 
    if(convertView==null){ 

     convertView= inflater.inflate(Resource,null); 
     holder= new ViewHolder(); 
     holder.hymntitle= (TextView) convertView.findViewById(R.id.Hymn_title); 
     // holder.hymntext= (TextView) convertView.findViewById(R.id.Channel_name); 


     convertView.setTag(holder); 

    }else{ 
     holder=(ViewHolder)convertView.getTag(); 
    } 

    holder.hymntitle.setText(hymnarray.get(position).getTitle()); 
    //holder.hymntext.setText(hymnarray.get(position).getText()); 

    return convertView; 


} 


    static class ViewHolder{ 

    public TextView hymntitle; 
    public TextView hymntext; 

} 

} 

Voici l'autre classe dans laquelle j'essaie d'implémenter le filtre. J'ai un edittext, où je textChangeListener mettre en œuvre sur

Answer 1

Vous pouvez utiliser l'interface filtrables sur votre adaptateur, voir un bon exemple ci-dessous:

original source et voir d'autres exemple here

public class SearchableAdapter extends BaseAdapter implements Filterable { 

    private List<String>originalData = null; 
    private List<String>filteredData = null; 
    private LayoutInflater mInflater; 
    private ItemFilter mFilter = new ItemFilter(); 

    public SearchableAdapter(Context context, List<String> data) { 
     this.filteredData = data ; 
     this.originalData = data ; 
     mInflater = LayoutInflater.from(context); 
    } 

    public int getCount() { 
     return filteredData.size(); 
    } 

    public Object getItem(int position) { 
     return filteredData.get(position); 
    } 

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

    public View getView(int position, View convertView, ViewGroup parent) { 
     // A ViewHolder keeps references to children views to avoid unnecessary calls 
     // to findViewById() on each row. 
     ViewHolder holder; 

     // When convertView is not null, we can reuse it directly, there is no need 
     // to reinflate it. We only inflate a new View when the convertView supplied 
     // by ListView is null. 
     if (convertView == null) { 
      convertView = mInflater.inflate(R.layout.list_item, null); 

      // Creates a ViewHolder and store references to the two children views 
      // we want to bind data to. 
      holder = new ViewHolder(); 
      holder.text = (TextView) convertView.findViewById(R.id.list_view); 

      // Bind the data efficiently with the holder. 

      convertView.setTag(holder); 
     } else { 
      // Get the ViewHolder back to get fast access to the TextView 
      // and the ImageView. 
      holder = (ViewHolder) convertView.getTag(); 
     } 

     // If weren't re-ordering this you could rely on what you set last time 
     holder.text.setText(filteredData.get(position)); 

     return convertView; 
    } 

    static class ViewHolder { 
     TextView text; 
    } 

    public Filter getFilter() { 
     return mFilter; 
    } 

    private class ItemFilter extends Filter { 
     @Override 
     protected FilterResults performFiltering(CharSequence constraint) { 

      String filterString = constraint.toString().toLowerCase(); 

      FilterResults results = new FilterResults(); 

      final List<String> list = originalData; 

      int count = list.size(); 
      final ArrayList<String> nlist = new ArrayList<String>(count); 

      String filterableString ; 

      for (int i = 0; i < count; i++) { 
       filterableString = list.get(i); 
       if (filterableString.toLowerCase().contains(filterString)) { 
        nlist.add(filterableString); 
       } 
      } 

      results.values = nlist; 
      results.count = nlist.size(); 

      return results; 
     } 

     @SuppressWarnings("unchecked") 
     @Override 
     protected void publishResults(CharSequence constraint, FilterResults results) { 
      filteredData = (ArrayList<String>) results.values; 
      notifyDataSetChanged(); 
     } 

    } 
} 

//in your Activity or Fragment where of Adapter is instantiated : 

editTxt.addTextChangedListener(new TextWatcher() { 

    @Override 
    public void onTextChanged(CharSequence s, int start, int before, int count) { 
     System.out.println("Text ["+s+"]"); 

     mSearchableAdapter.getFilter().filter(s.toString());       
    } 

    @Override 
    public void beforeTextChanged(CharSequence s, int start, int count, 
      int after) { 

    } 

    @Override

vous pouvez trouver la classe d'adaptateur de liste personnalisée avec filtrable en utilisant le changement de texte dans le texte d'édition ...

créer une liste personnalisée classe d'adaptateur avec la mise en œuvre de filtrables:

private class CustomListAdapter extends BaseAdapter implements Filterable{ 

    private LayoutInflater inflater; 
    private ViewHolder holder; 
    private ItemFilter mFilter = new ItemFilter();

    }); 

Answer 4

Une chose que j'ai remarqué est que chaque fois que vous modifiez la liste (ajout d'éléments, par exemple), ainsi que le filtrage pour, puis à l'intérieur du @Override getView méthode, vous ne devez pas utiliser filteredData.get(position), car il déclenche une exception IndexOutOfBounds. Au lieu de cela, ce qui a fonctionné pour moi, utilisait la méthode getItem(position), qui appartient à la classe ArrayAdapter.

Answer 5

Vous devez d'abord créer l'EditText dans le fichier xml et affecter un ID, par exemple con_pag_etPesquisa. Après cela, nous allons créer deux listes, où l'une est la vue liste et l'autre pour recevoir le même contenu, mais restera comme une sauvegarde. Avant déplacer des objets à la liste d'abord les initialise le ci-dessous:

//Declaring 

public EditText etPesquisa; 

public ContasPagarAdapter adapterNormal; 

public List<ContasPagar> lstBkp; 

public List<ContasPagar> lstCp; 

//Within the onCreate method, type the following: 

etPesquisa = (EditText) findViewById(R.id.con_pag_etPesquisa); 

etPesquisa.addTextChangedListener(new TextWatcher(){ 

    @Override 
    public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3){ 
     filter(String.valueOf(cs)); 
    } 
    @Override 
    public void beforeTextChanged(CharSequence cs, int arg1, int arg2, int arg3){ 

    // TODO Auto-generated method stub 
    } 
    @Override 
    public void afterTextChanged(Editable e){ 

    } 

}); 

//Before moving objects to lists first initializes them as below: 

lstCp = new ArrayList<ContasPagar>(); 

lstBkp = new ArrayList<ContasPagar>(); 


//When you add objects to the main list, repeat the procedure also for bkp list, as follows: 

lstCp.add(cp); 

lstBkp.add(cp); 


//Now initializes the adapter and let the listener, as follows: 

adapterNormal = new ContasPagarAdapter(ContasPagarActivity.this, lstCp); 

lvContasPagar.setAdapter(adapterNormal); 
        lvContasPagar.setOnItemClickListener(verificaClickItemContasPagar(lstCp)); 


//Now create the methods inside actito filter the text entered by the user, as follows: 

public void filter(String charText){ 

    charText = charText.toLowerCase(); 

    lstCp.clear(); 

    if (charText.length() == 0){ 

     lstCp.addAll(lstBkp); 

     appendAddItem(lstBkp); 

    } 

    else { 

     for (int i = 0; i < lstBkp.size(); i++){ 

      if((lstBkp.get(i).getNome_lancamento() + " - " + String.valueOf(lstBkp.get(i).getCodigo())).toLowerCase().contains(charText)){ 

       lstCp.add(lstBkp.get(i)); 

      } 

     } 

     appendAddItem(lstCp); 
    } 
} 

private void appendAddItem(final List<ContasPagar> novaLista){ 
    runOnUiThread(new Runnable(){ 

     @Override 
      public void run(){ 
       adapterNormal.notifyDataSetChanged();    
      } 
     }); 
    } 

Answer 6

J'espère que ce sera utile pour les autres.

// put below code (method) in Adapter class 
public void filter(String charText) { 
    charText = charText.toLowerCase(Locale.getDefault()); 
    myList.clear(); 
    if (charText.length() == 0) { 
     myList.addAll(arraylist); 
    } 
    else 
    { 
     for (MyBean wp : arraylist) { 
      if (wp.getName().toLowerCase(Locale.getDefault()).contains(charText)) { 
       myList.add(wp); 
      } 
     } 
    } 
    notifyDataSetChanged(); 
} 

déclarent ci-dessous code dans la classe de l'adaptateur

private ArrayList<MyBean> myList; // for loading main list 
private ArrayList<MyBean> arraylist=null; // for loading filter data 

ci-dessous code dans l'adaptateur Constructor

this.arraylist = new ArrayList<MyBean>(); 
    this.arraylist.addAll(myList); 

et au-dessous du code dans votre classe d'activité

final EditText searchET = (EditText)findViewById(R.id.search_et); 
    // Capture Text in EditText 
    searchET.addTextChangedListener(new TextWatcher() { 

     @Override 
     public void afterTextChanged(Editable arg0) { 
      // TODO Auto-generated method stub 
      String text = searchET.getText().toString().toLowerCase(Locale.getDefault()); 
      adapter.filter(text); 
     } 

     @Override 
     public void beforeTextChanged(CharSequence arg0, int arg1, 
             int arg2, int arg3) { 
      // TODO Auto-generated method stub 
     } 

     @Override 
     public void onTextChanged(CharSequence arg0, int arg1, int arg2, 
            int arg3) { 
      // TODO Auto-generated method stub 
     } 
    }); 

Answer 7

Vous pouvez mettre en œuvre filtre de recherche dans listview de deux manières. 1. en utilisant searchview 2. en utilisant edittext.

1. Si yo voulez utiliser SearchView puis lire ici: searchview filter.

2. Si vous souhaitez utiliser edittext, lire ci-dessous.

J'ai pris référence à partir de: listview search filter android

extraits de code pour faire filtre avec edittext.

Première classe modèle créer MovieNames.java:

public class MovieNames { 
    private String movieName; 

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

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

} 

Créer un fichier 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> 

Marque classe ListViewAdapter.java:

import android.content.Context; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.BaseAdapter; 
import android.widget.TextView; 

import java.util.ArrayList; 
import java.util.Locale; 

public class ListViewAdapter extends BaseAdapter { 

    // Declare Variables 

    Context mContext; 
    LayoutInflater inflater; 
    private ArrayList<MovieNames> arraylist; 

    public ListViewAdapter(Context context, ArrayList<MovieNames> arraylist) { 
     mContext = context; 
     inflater = LayoutInflater.from(mContext); 
     this.arraylist = arraylist; 

    } 

    public class ViewHolder { 
     TextView name; 
    } 

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

    @Override 
    public MovieNames getItem(int position) { 
     return arraylist.get(position); 
    } 

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

    public View getView(final int position, View view, ViewGroup parent) { 
     final ViewHolder holder; 
     if (view == null) { 
      holder = new ViewHolder(); 
      view = inflater.inflate(R.layout.listview_item, null); 
      // Locate the TextViews in listview_item.xml 
      holder.name = (TextView) view.findViewById(R.id.name); 
      view.setTag(holder); 
     } else { 
      holder = (ViewHolder) view.getTag(); 
     } 
     // Set the results into TextViews 
     holder.name.setText(arraylist.get(position).getMovieName()); 
     return view; 
    }
