通过按钮显示隐藏listview中的数据

由显示到隐藏进行页面的转换的时候会调用原页面的onResume()方法，该情况下在onResume()中显示数据

@Overrideprotected void onResume() {// TODO Auto-generated method stubsuper.onResume();new Thread() {public void run() {mSystemList = new ArrayList<AppInfo>();mSdcardList = new ArrayList<AppInfo>();mInfoList = AppInfoProvider.getAppInfoList(getApplicationContext());for (AppInfo info : mInfoList) {if (info.isSystem()) {mSystemList.add(info);} else {mSdcardList.add(info);}}mSystemListSize = mSystemList.size();mSdcardListSize = mSdcardList.size();mHandler.sendEmptyMessage(0);};}.start();}
