So implementieren Sie die Suchfunktionalität für benutzerdefinierte Listenansicht

Question

Ich habe die Suchleiste in meine App eingefügt, aber ich kann keine Suche nach den Listenansichtselementen durchführen ... Der Bearbeitungstext nimmt zwar Eingaben vor, führt jedoch keine Suche durch.

hier ist mein Code:

MainActivity.java

import android.os.Bundle; 
import android.support.v7.app.AppCompatActivity; 
import android.view.View; 
import android.widget.AdapterView;

import android.widget.ListView; 

public class first extends AppCompatActivity { 
EditText inputSearch; 
private ListView listView; 
private String[] names = {"प्रार्थना", "सुखकर्ता दु:खहर्ता", "गजानना श्रीगणराया", "येई हो विठ्ठले", "लवथवती विक्राळा", "दुर्गे दुर्घट भारी", "आरती ज्ञानराजा", 
     "हे भोळ्या शंकरा", "ओवाळू", "मंगेशा महारूद्रा", "आला गणराया", "शेंदुर लाल चढायो", "एकदंता", "कर्पूर गौरा", "हे गजवधना", "प्रथमेश्वरा", "जयदेवा हे साईनाथा",

       startActivityForResult(myIntent, 0); 
      } 
      if (position == 18) {

       startActivityForResult(myIntent, 0); 
      } 
     } 
    }); 
} 
} 

hier ist der Code für CustomList.java

public class CustomList extends ArrayAdapter<String> { 
    private String[] names; 
    private Integer[] imageid; 
    private Activity context; 

    public CustomList(Activity context, String[] names, Integer[] imageid) { 
     super(context,R.layout.list_layout,names); 
     this.context = context; 
     this.names = names; 
     this.imageid = imageid; 

    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     LayoutInflater inflater = context.getLayoutInflater(); 
     View listViewItem = inflater.inflate(R.layout.list_layout, null, true); 
     TextView textViewName = (TextView) listViewItem.findViewById(R.id.textViewName); 
     ImageView image = (ImageView) listViewItem.findViewById(R.id.imageView); 
     textViewName.setText(names[position]); 
     image.setImageResource(imageid[position]); 
     return listViewItem; 
    } 
}

Ich denke, es nicht um eine Suche macht, weil man nichts tun mit dem EditText. Was Sie tun können:

1. Stellen Sie einen "Text geändert" Hörer (EditText des addTextChangedListener() -Methode) in OnCreate()
2. in OnTextChanged() Sie können den Text erhalten, die auf dem Eingang ist
3. Update die Daten entsprechend (z. B. names.contains() -Methode)
4. die Daten an die ListView übergeben und notifyDataSetChanged() aufrufen. Oder erstellen Sie die Liste mit den neuen Daten neu.
