Android 判斷當前的介面是否是桌面的方法

判斷當前介面是否是桌面：

public boolean isHome() {
        String packname = "";
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            List<UsageStats> queryUsageStats = getUsageStats();
            if (queryUsageStats != null && !queryUsageStats.isEmpty()) {
                UsageStats recentStats = null;
                for (UsageStats usageStats : queryUsageStats) {
                    if (recentStats == null
                            || recentStats.getLastTimeUsed() < usageStats.getLastTimeUsed()) {
                        recentStats = usageStats;
                    }
                }
                packname = recentStats.getPackageName();
            }
        } else {
            List<RunningTaskInfo> rti = mAManager.getRunningTasks(1);
            packname = rti.get(0).topActivity.getPackageName();
        }
        return getHomes().contains(packname);
    }

獲得屬於桌面的應用的應用包名稱：

private List<String> getHomes() {
        List<String> names = new ArrayList<String>();
        PackageManager packageManager = BaseApp.APP.getPackageManager();
        // 屬性
        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;
    }
