禁用 Android 幼儿应用程序中的主页按钮?
我开发了一个应用程序,它是一个图片幻灯片放映,当您点击它们时,每个图片都会播放声音。这就像一本适合2-4岁孩子的图画书。
问题是,由于 Android 不会让您捕获按下主页按钮并基本上禁用它,因此当父母将手机交给孩子与无人看管(勇敢的父母)一起玩时,孩子可能会无意中退出应用程序,然后拨打电话或否则调整手机。
目前还有另外两个应用程序针对此问题提供了伪修复。这些应用程序是 Toddler Lock 和 ToddlePhone。我尝试联系这些应用程序的开发人员寻求一些指导,但他们不愿意透露任何信息,如果可以的话,但是这里有人有任何建议吗?
看起来这两个其他应用程序的作用就像主屏幕替换应用程序。当您在这些应用程序上启用“儿童防护模式”时,系统会提示用户选择要执行操作的应用程序,选项包括“Launcher、LauncherPro 等”。加上幼儿应用程序。然后,您必须将幼儿应用程序设置为默认应用程序,瞧,手机被“锁定”,并且在“解锁”手机时只能使用组合键或触摸屏幕的四个角等来“解锁”。您的正常主屏幕应用程序默认已恢复。下次启用“儿童安全模式”时,您甚至不必将幼儿应用程序设置为默认应用程序。
我读到这两个应用程序在三星手机上存在问题,它们可能会导致无限的崩溃和重启循环,需要恢复出厂设置才能修复。显然,这不是解决问题的理想解决方案,但它看起来是目前唯一可用的解决方案。
有人对如何实施“儿童安全模式”有任何想法吗?
I've developed and app that is a slide show of pictures which each play a sound when you tap them. It's like a picture book for ages 2-4.
The problem is, since android won't let you capture a home button press and essentially disable it, when parents give the phone to their child to play with unattended (brave parent), the child can inadvertenly exit the app and then make calls or otherwise tweak the phone.
There are two other apps that currently have a psuedo fix for this issue. The apps are Toddler Lock and ToddlePhone. I've tried contacting the developers of these apps for some guidance but they haven't been willing to disclose anything, which if fine, but does anyone here have any suggestions?
It looks like both of those other apps are acting like a home screen replacement app. When you enable the "childproof mode" on those apps the user is prompted to chose and app for the action and the choices are "Launcher, LauncherPro, etc." plus the toddler app. You then have to make the toddler app the default and voila, the phone is "locked" and can only be "unlocked" using a key combination or touching the four corners of the screen, etc. when you "unlock" the phone. your normal home screen app default restored. You don't even have to make the toddler app the default the next time you enable the "childproof mode".
I have read that these two apps have problems with Samsung phones and they can cause an an infinite crash-and-restart-loop that requires a factory reset to fix. Obviously this is not the ideal solution to the problem but it looks like the only one availiable at this point.
Does anyone have any ideas on how to implement a "childproof mode"?

我需要让幼儿锁定新的应用程序,并且不想使用启动器。
这是我所做的,您可以在 https://play.google.com/store/apps/details?id=com.justforkids.animalsounds" rel="noreferrer">https:/ /play.google.com/store/apps/details?id=com.justforkids.animalsounds
对于步骤 3,这里有更多详细信息:
创建覆盖布局,例如文件locked_overlay.xml:
在您的服务中显示或隐藏覆盖使用:
您将需要权限
I needed to have toddler lock in a new app, and did not want to use a launcher.
Here is what I did, you can see the app at https://play.google.com/store/apps/details?id=com.justforkids.animalsounds
For step 3, here are more details:
Create the overlay layout, for example file locked_overlay.xml:
In your service to show or hide the overlay use:
You will need the permission
我认为您关于更换主屏幕的看法是正确的。我知道幼儿锁不会覆盖主页按钮,因为(至少在我的 LG GW620 上)在幼儿锁中按住主页按钮会弹出 ALT-TAB 类型菜单 - 这往往会导致手机崩溃。
Android 开发网站上有一个主屏幕替换应用程序,带有源代码:

I think you're right regarding the home screen replacement. Toddler Lock I know doesn't override the home button, because (at least on my LG GW620) while in Toddle Lock holding the home button brings up the ALT-TAB type menu - which then tends to crash the phone.
There is a home screen replacement app available, with source code, on the android dev site:

EDIT: also, ADW.Launcher:

这适用于所有旧版本的 Android。但在 ICS 和 jelly bean 中不起作用,并且会导致应用程序崩溃
Edit:
This works in all older version of android. But will not work in ICS and jelly bean and will give you crash in app
对于 4.0 及更高版本,您可以避免 Android 安全限制并将您的应用程序设置为启动器。将其添加到您的清单文件中:
For versions 4.0 and above you can avoid Android security restrictions and set your app as a launcher. Add this to your manifest file:
我使用以下代码替换了默认主页启动器:
I replaced the Default Home launcher using the following code:
