我想在模拟器中测试我的应用程序的可访问性(特别是 Talkback)，但模拟器中似乎缺少该选项.这是模拟器在辅助功能设置中的屏幕截图:
I want to test the accessibility of my app in emulator (particularly Talkback) but it seems that the option is missing in emulator. Here is the screen shot from the emulator in accessibility settings:
有两个选项 "ClockBack" 和 "QueryBack" 我在我的手机上找不到相同的 android 版本.这是我手机的无障碍设置截图:
There are two options "ClockBack" and "QueryBack" which I couldn't find on my phone with the same android version. Here is the screenshot of the accessibility setting of my phone:
我搜索了解 "ClockBack" 和 "QueryBack" 以查看它们是否是模拟器中 Talkback 的替代品，但我什么都找不到.
I searched to learn about "ClockBack" and "QueryBack" to see if they are replacement of Talkback in emulator but I couldn't find anything.
有谁知道ClockBack"和QueryBack"的功能是什么?还有更多关于如何在模拟器中启用Talkback?
Does any one know what is the functionality of "ClockBack" and "QueryBack"? And more over how to enable Talkback in emulator?
......
模拟器好像默认没有Talkback 所以下载"TalkBack" apk并将其安装在模拟器上，该选项已启用.
It seems that the emulator doesn't contain Talkback by default so after downloading "TalkBack" apk and install it on the emulator, the option has been enabled.
