判断当前界面是否是桌面整体思路

通过ActivityManager获知topActivity的包名
通过PackageManager和桌面Intent(Category_HOME,ACTION_MAIN)查询到所有桌面应用的包名
看步骤2的列表中是否含有步骤1的包名，是则为桌面，否则不是

/***判断当前界面是否为桌面*/private boolean isHome() {        ActivityManager mActivityManager = (ActivityManager)  getSystemService(Context.ACTIVITY_SERVICE);        List<RunningTaskInfo> rti = mActivityManager.getRunningTasks(1);        return getHomes().contains(rti.get(0).topActivity.getPackageName());    }/*** 获得属于桌面的应用的应用包名称* * @return 返回包含所有包名的字符串列表*/private List<String> getHomes() {        List<String> names = new ArrayList<String>();        PackageManager packageManager = this.getPackageManager();        Intent intent = new Intent(Intent.ACTION_MAIN);        intent.addCategory(Intent.CATEGORY_HOME);        List<ResolveInfo> resolveInfo = packageManager.queryIntentActivities(intent,                PackageManager.MATCH_DEFAULT_ONLY);        for (ResolveInfo ri : resolveInfo) {            names.add(ri.activityInfo.packageName);        }        return names;    }
