public class MainActivity extends Activity {
    	public void onCreate(Bundle savedInstanceState) {
    		super.onCreate(savedInstanceState);
    	}
    
    	@Override
    	protected void onStart() {
    		super.onStart();
    		StringBuilder serviceInfo = new StringBuilder();
    		ActivityManager manager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
    		List<RunningServiceInfo> services = manager.getRunningServices(100);// 获得正在运行的服务列表
    		for (Iterator<RunningServiceInfo> it = services.iterator(); it
    				.hasNext();) {
    			RunningServiceInfo info = it.next();
    			// 获得一个服务的详细信息并保存到StringBuilder
    			serviceInfo.append("activeSince: " + formatData(info.activeSince)
    					+ "\n");
    			serviceInfo.append("clientCount: " + info.clientCount + "\n");
    			serviceInfo.append("clientLabel: " + info.clientLabel + "\n");
    			serviceInfo.append("clientPackage: " + info.clientPackage + "\n");
    			serviceInfo.append("crashCount: " + info.crashCount + "\n");
    			serviceInfo.append("flags: " + info.flags + "\n");
    			serviceInfo.append("foreground: " + info.foreground + "\n");
    			serviceInfo.append("lastActivityTime: "
    					+ formatData(info.lastActivityTime) + "\n");
    			serviceInfo.append("pid: " + info.pid + "\n");
    			serviceInfo.append("process: " + info.process + "\n");
    			serviceInfo.append("restarting: " + formatData(info.restarting)

    			serviceInfo.append("\n");
    		}
    
    		ScrollView scrollView = new ScrollView(this);// 创建滚动视图
    		TextView textView = new TextView(this);// 创建文本视图
    		textView.setBackgroundColor(Color.BLACK);// 设置文本颜色
    		textView.setTextSize(25);// 设置字体大小
    		textView.setText(serviceInfo.toString());// 设置文本内容
    		scrollView.addView(textView);// 将文本视图增加到滚动视图
    		setContentView(scrollView);// 显示滚动视图
    	}
    
    	private static String formatData(long data) {// 用于格式化时间
    		SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    		return format.format(new Date(data));
    	}
    }
