Android 从列表视图中筛选出系统包

如何在列表中使用此方法从列表中筛选出系统包

我目前有以下方法：

public static List<ApplicationInfo> getInstalledApplication(Context context) {
    PackageManager packageManager = context.getPackageManager();

    List<ApplicationInfo> apps = packageManager.getInstalledApplications(0);
    Collections.sort(apps, new ApplicationInfo.DisplayNameComparator(packageManager));
    return apps;
}

---

这将过滤掉系统包：

public static List<ApplicationInfo> getInstalledApplication(Context context) {
    PackageManager packageManager = context.getPackageManager();
    List<ApplicationInfo> apps = packageManager.getInstalledApplications(0);
    Collections.sort(apps, new ApplicationInfo.DisplayNameComparator(packageManager));
    Iterator<ApplicationInfo> it = apps.iterator();
    while (it.hasNext()) {
        ApplicationInfo ai = it.next();
        if ((ai.flags & ApplicationInfo.FLAG_SYSTEM) != 0) {
            it.remove();
        }
    }
    return apps;
}

公共静态列表getInstalledApplication（上下文）{
PackageManager PackageManager=context.getPackageManager（）；
列表应用程序=packageManager.GetInstalledApplication（0）；
Collections.sort（apps，新的ApplicationInfo.DisplayNameComparator（packageManager））；
Iterator it=apps.Iterator（）；
while（it.hasNext（））{
ApplicationInfo ai=it.next（）；
如果（（ai.flags&ApplicationInfo.FLAG\u系统）！=0）{
it.remove（）；
}
}
返回应用程序；
}

首先，三元运算符在那里是无用的。只需返回

（（ri.activityInfo.applicationInfo.flags和applicationInfo.FLAG\u系统）！=0

。所以你有这个方法…很好。问题是…？但是我需要返回系统包，但要返回我的集合。排序方法比较器只知道如何根据你定义的顺序进行排序。为什么不发布你试图删除这些项的完整代码？

public static List<ApplicationInfo> getInstalledApplication(Context context) {
    PackageManager packageManager = context.getPackageManager();
    List<ApplicationInfo> apps = packageManager.getInstalledApplications(0);
    Collections.sort(apps, new ApplicationInfo.DisplayNameComparator(packageManager));
    Iterator<ApplicationInfo> it = apps.iterator();
    while (it.hasNext()) {
        ApplicationInfo ai = it.next();
        if ((ai.flags & ApplicationInfo.FLAG_SYSTEM) != 0) {
            it.remove();
        }
    }
    return apps;
}
