android ListActivity

摘要: ListActivity

今天看Android-PullToRefresh的源代码，先从它的例子看到LauncherActivity继承了ListActivity，以前只接触过Activity，瞬间觉得自己渺小啦，

在onCreate中将item的内容加入，使用setListAdapter并设置List的格式

setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, options));

第一个参数是对象，第二个参数是list的样式，第三个是List的内容。

点击是List返回的方法

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);
}

这有掌握一个知识点。。。。加油
