android - 如何刷新 ListView 控件；

Question

我在mMessageReceiver中修改了ListView控件的源数据，但是ListView控件还是显示旧行，如何刷新 mMessageReceiver 中的 ListView 控件？谢谢!

   private ListView lv; 

private BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        HandleRule.SaveFullRule(PublicPar.SharedRule);
        //I hope to refresh ListView control
    }
};


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.sms_main);  

    LocalBroadcastManager.getInstance(this).registerReceiver(mMessageReceiver,
              new IntentFilter(PublicPar.LocalBroadcastForRule));

    PublicPar.myContext=getApplicationContext();        
    lv = getListView(); 

        FillListView(); 
}

private void FillListView(){
    Cursor c=HandleRule.GetCursorOfAllRuleMain();       
    String[] cols=new String[] {"name"};
    int[] views=new int[]{R.id.mylisttext};
    SimpleCursorAdapter myAdapter=new SimpleCursorAdapter(this,R.layout.sms_simple_list_item_multiple_choice,c,cols,views);
    lv.setAdapter(myAdapter);
    lv.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);    
    SetCheckBoxStatus();
}

Answer 1

myAdapter..notifyDataSetChanged();
