启动程序，获取程序信息：
代码如下：
创建一个AppInfo类来表示应用程序
&pre name=&code& class=&java&&public class AppInfo {
public CharS// 程序名
public CharSequence packageN // 程序包名
I// 启动Intent
public D// 程序图标
* 设置启动该程序的Intent
final void setActivity(ComponentName className, int launchFlags) {
intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
intent.setComponent(className);
intent.setFlags(launchFlags);
创建程序列表的适配器：

做从未做的事，叫成长；做不愿做的事，叫改变；做不敢做的事，叫突破。在学习中成长，在正向里改变，在尝试时突破，给人生一次变好的机会。生命，要用智慧驾驭，用从容相随，用简单诠释，用自由概括，用快乐装饰，用希望照耀，用成功证明，用心灵体验，或许凡俗但真实，或许平庸但挚诚。
