如何插入表中的數據，而無需刷新它

Question

我已在安卓下面的程序使用ListActivity：

package com.infy.dataloaderdemo; 

import java.util.ArrayList; 

import android.app.ListActivity; 
import android.database.Cursor; 
import android.os.Bundle; 
import android.provider.Browser; 
import android.util.Log; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.ArrayAdapter; 
import android.widget.Button; 
import android.widget.EditText; 
import android.widget.ListView; 
import android.widget.SimpleCursorAdapter; 

public class DataLoaderOfDataBase extends ListActivity { 
    /** Called when the activity is first created. */ 
    ListView listView; 
    ArrayList<String> arrayList=new ArrayList<String>(); 
    Cursor mCursor; 
    Button mButton; 
    EditText e; 
    public static final String KEY_ROWID = "_id"; 
    public static final String KEY_ISBN = "isbn"; 

    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.dataloaderlist); 


    } 


     @Override 
    protected void onStart() { 
     // TODO Auto-generated method stub 
     super.onStart(); 

     mButton=(Button)findViewById(R.id.push); 
     mButton.setOnClickListener(new OnClickListener(){ 

      @Override 
      public void onClick(View v) { 
       // TODO Auto-generated method stub 

       pushDataInList(); 

      } 

     }); 
    } 

    public void pushDataInList(){ 
     String[] displayFields = new String[] {KEY_ROWID,KEY_ISBN}; 

     int[] displayViews = new int[] { android.R.id.text1,android.R.id.text2 }; 

     // Cursor cur = managedQuery(android.provider.Browser.BOOKMARKS_URI,projection, null, null, null); 
     DBAdapter dbAdapter=new DBAdapter(this); 

     long l=dbAdapter.insertTitle("new"); 
     Log.e("l", ""+l); 
     Cursor cur=null; 


     //cur=dbAdapter.getTitle(2); 
     cur = dbAdapter.getAllTitles(); 

     int i=cur.getCount(); 
     Log.e("c", ""+i); 
     setListAdapter(new SimpleCursorAdapter(this,android.R.layout.simple_list_item_2,cur,displayFields,displayViews)); 


    } 

} 

每當我添加一個數據，整個名單得到更新。有沒有什麼方法可以在List中添加數據而不刷新它？

Answer 1

撥打setNotifyOnChange與false停止自動通知，然後再開始向列表中添加數據。完成後，再次撥打電話true。
