前言
相信用过工具类的各位仁兄都觉得工具类好用，本人不才，今天斗胆拿出一个自己感觉还行的的工具类。
1、Activity控制类
public class ActivityCollector{ //activity集合 public static List<Activity> mActList = new ArrayList<Activity>(); /** * 添加Activity * * @param activity */ public static void addActivity(Activity activity){ mActList.add.add(activity); } } /** * 移除Activity */ public static void removeActivity(Activity activity) { mActList.remove(activity); } /** * 退出 */ public static void finishAll() { for (Activity activity : mActList) { if (!activity.isFinishing()) { activity.finish(); } } }}2、应用市场管理类
public class MarketUtils { // 360手机助手 public static final String MARKET = "com.qihoo.appstore"; // 淘宝手机助手 public static final String MARKET_TAOBAO = "com.taobao.appcenter"; // 应用宝 public static final String MARKET_QQDOWNLOADER = "com.tencent.Android.qqdownloader"; // 安卓市场 public static final String MARKET_HIAPK = "com.hiapk.marketpho"; // 安智市场 public static final String MARKET_GOAPK = "cn.goapk.market"; // 包名 public static final String APP_PACKAGE_NAME = "com.*.*"; public MarketUtils() { throw new AssertionError();} /** * 跳转到应用市场 * * @param appPkg * ：上传到应用市场上app的包名,不是本项目的包名 * @param marketPkg * ：应用市场的包名 */ public static void goToMarket(Context context, String packageName) { Uri uri = Uri.parse("market://details?id=" + packageName); Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri); try { context.startActivity(goToMarket); } catch (ActivityNotFoundException e) { }} /** * 启动App * * @param context */ public static void launchapp(Context context) { // 判断是否安装过App，否则去市场下载 if (isAppInstalled(context, APP_PACKAGE_NAME)) { context.startActivity(context.getPackageManager() .getLaunchIntentForPackage(APP_PACKAGE_NAME)); } else { goToMarket(context, APP_PACKAGE_NAME); }} /** * 检测某个应用是否安装 * * @param context * @param packageName * @return */ public static boolean isAppInstalled(Context context, String packageName) { try { context.getPackageManager().getPackageInfo(packageName, 0); return true; } catch (NameNotFoundException e) { return false; }} /** * 判断市场是否存在的方法 * * @param context * @param packageName * 应用市场包名 * @return true or false */ public static boolean isAvilible(Context context, String packageName) { final PackageManager packageManager = context.getPackageManager();// 获取packagemanager List<PackageInfo> packageInfo = packageManager.getInstalledPackages(0);// 获取所有已安装程序的包信息 List<String> NameList = new ArrayList<String>();// 用于存储所有已安装程序的包名 // 从packageInfo中取出包名，放入NameList中 if (packageInfo != null) { for (int i = 0; i < packageInfo.size(); i++) { String pn = packageInfo.get(i).packageName; NameList.add(pn); } } return NameList.contains(packageName);// 判断pName中是否有目标程序的包名，有TRUE，没有FALSE} }3、Toast工具类（不建议使用）
