add item at the List listview android

Question

Aquí hay un ejemplo que presenta los valores dinámicos getviewview de list1. Ahora me gustaría agregar el artículo en la posición final (por fin). El texto no sobrescribe el elemento cuando lo insertamos. Será paginación del artículo. Por favor, alguien me ayude?

package com.list.viewer; 

import android.app.Activity; 
import android.content.Context; 
import android.os.Bundle; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.AbsListView; 
import android.widget.BaseAdapter; 
import android.widget.Button; 
import android.widget.ListView; 
import android.widget.TextView; 

/** http://www.android-codes-examples.blogspot.com/ */ 
public class ListViewExample extends Activity { 

    private String[] list1 = { "Icon", "Icon Creator", "Image", "Image Creator" }; 

    private ListView lister1; 

    Button btn_add; 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
     lister1 = (ListView) findViewById(R.id.ListView1); 
    btn_add =(Button)findViewById(R.id.btn_add); 
    String[] list2 = { "nikunj", "patel", "hi", "this" }; 
    ItemsAdapter itemsAdapter = new ItemsAdapter(ListViewExample.this, 
      R.layout.list, list2); 
    lister1.setAdapter(itemsAdapter); 
    btn_add.setOnClickListener(new View.OnClickListener() { 
     public void onClick(View v) { 
      // Perform action on click 
      String[] list2 = { "nikunj", "patel", "hi", "this" }; 
      ItemsAdapter itemsAdapter = new ItemsAdapter(ListViewExample.this, 
        R.layout.list, list2); 
      lister1.setAdapter(itemsAdapter); 

     } 
    }); 

     /*lister1.setOnItemClickListener(new OnItemClickListener() { 

      @Override 
      public void onItemClick(AdapterView<?> arg0, View arg1, 
        int positon, long arg3) { 
       String[] lister = null; 
       switch (positon) { 
       case 0: 
        lister = list21; 
        break; 
       case 1: 
        lister = list22; 
        break; 
       case 2: 
        lister = list23; 
        break; 
       case 3: 
        lister = list24; 
        break; 
       default: 
        lister = list21; 
       } 
       lister2.setAdapter(new ArrayAdapter<String>(
         ListViewExample.this, 
         android.R.layout.simple_list_item_1, lister)); 
      } 
     });*/ 
    } 

    private class ItemsAdapter extends BaseAdapter { 
     String[] items; 

     public ItemsAdapter(Context context, int textViewResourceId, 
       String[] items) { 
      this.items = items; 
     } 

     @Override 
     public View getView(final int position, View convertView, 
       ViewGroup parent) { 
      System.out.println("position is "+position); 
      TextView mDescription; 
      View view = convertView; 
      //ImageView image; 
      if (view == null) { 
       LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
       view = vi.inflate(R.layout.list, null); 
      } 
      if(position == 3) 
      { 
       mDescription = (TextView) view.findViewById(R.id.desc); 
       mDescription.setText(items[position]); 
      }else 
      { 
       mDescription = (TextView) view.findViewById(R.id.desc); 
       mDescription.setText(items[position]); 

      } 
      //image = (ImageView) view.findViewById(R.id.image); 

      //image.setBackgroundResource(R.id.image); 
      return view; 
     } 

     public int getCount() { 
      return items.length; 
     } 

     public Object getItem(int position) { 
      return position; 
     } 

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

Answer 1

Se puede añadir un "Pie de página" que siempre se mostrará en la parte inferior de su lista:

View footerView = getLayoutInflater().inflate(R.layout.footer_layout, lister1, false); 
lister1.addFooterView(footerView); 

Answer 2

Al añadir un nuevo elemento en su dataSource va a actualizar el adaptador por

itemsAdapter.notifyDataSetChanged();
