是所有在现代设备上的触摸屏,功能在硬件级别(如果软件支持它)?
如果不是如何检测触摸屏屏幕本身的方法是多点触摸的吗?

Are all touch-screens on modern devices multitouch capable on hardware level (if software supports it)?
If not than how to detect if touchscreen screen by itself is multitouch or not?

这在没有曾经创建的每个Android设备的情况下或多或少地没有规范表(在您考虑的任何时间范围内")。非常广泛地说,最近几年的主要制造商的设备通常会在某种程度上支持多点,但即使是设备之间的整体支持程度也会有所不同。
如果不是如何检测触摸屏屏幕的方法是 multitouch或不是?
这个的应用程序。我会说选择一个并尝试一下。如果您想尝试验证结果,请选择几个并尝试所有。

This is more or less impossible to answer without spec sheets for every Android device that has ever been created (within whatever timeframe you consider "modern"). Very broadly speaking, devices from major manufacturers over the last several years will typically support multitouch to some degree, but even that overall degree of support can vary between devices.

There are a bunch of apps for this. I'd say pick one and try it. If you want to try to verify the results, pick several and try them all.
如果要以编程方式检查,请检查通过PackAgeManager对象的系统功能,据我所知,我可以告诉我的设备。此方法没有提供确切的支持号码,而是如下分类:
取决于您的任务,这可能足够了,但是Gathrawn关于低级手机的评论让我担心,如果可以依赖于所有这些供应商在部署软件之前正确设置这些值。
除此之外,我目前不知道任何方式(但也想了解一个) - 除了您的用户在应用程序启动时,如果检测到的API级别小于11例如。
If you want to check programmatically, checking the system features via the PackageManager object works, as far as i can tell for my device. This method doesn't give the exact supported number, but rather a categorisation as follows:
Depending on your task as hand, this might be sufficient enough, however GAThrawn's comment regarding low-tier phones makes me worry if it can be relied on that all those vendors actually set those values correctly before deploying the software.
Other than that, i don't know any way currently (but would also like to learn about one) - apart from maybe having the users test their devices as your app starts up, when the detected api level is less than 11 for instance.
