android下拉刷新带自定义声音

来源：互联网发布：js 银行卡格式编辑：程序博客网时间：2024/05/14 18:06

写这篇文章时，我android开发已经半年多了，今天刚做完下拉刷新带声音，比如你R.raw导入的声音是某人唱的也可以哦，但是下拉刷新下声音不会太长就1.2秒的事呵呵。废话不说直接看代码！

public class LauncherActivity extends ListActivity {//主页面activity点击第一个listview进入下拉刷新滑动带声音的activity

public static final String[] options = { "下拉刷新滑动带声音", "ExpandableListView（QQ分组）", "GridView（下拉刷新出现格子数据）", "WebView", "ScrollView",
   "Horizontal ScrollView（左右侧滑）", "ViewPager", "ListView Fragment", "WebView Advanced", "ListView in ViewPager","学习","很重要" };
@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, options));
}

@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
Intent intent;

  switch (position) {
   default:
   case 0:
    intent = new Intent(this, PullToRefreshListActivity.class);
    break;
   case 1:
    intent = new Intent(this, PullToRefreshExpandableListActivity.class);
    break;
   case 2:
    intent = new Intent(this, PullToRefreshGridActivity.class);
    break;
   case 3:
    intent = new Intent(this, PullToRefreshWebViewActivity.class);
    break;
   case 4:
    intent = new Intent(this, PullToRefreshScrollViewActivity.class);
    break;
   case 5:
    intent = new Intent(this, PullToRefreshHorizontalScrollViewActivity.class);
    break;
   case 6:
    intent = new Intent(this, PullToRefreshViewPagerActivity.class);
    break;
   case 7:
    intent = new Intent(this, PullToRefreshListFragmentActivity.class);
    break;
   case 8:
    intent = new Intent(this, PullToRefreshWebView2Activity.class);
    break;
   case 9:
    intent = new Intent(this, PullToRefreshListInViewPagerActivity.class);
    break;
  }

startActivity(intent);
}

}

//看配置文件 simple_list_item_1.xml
