Detecting if screen can send touch events or not on Android?

How do I detect whether or not the screen on an android device is a touchscreen?

I don't want to force the user to "press here" and see if I get an event, I'd like to detect it without asking the user to do开发者_JAVA技巧 anything.

You can use the hasSystemFeature method of the PackageManager class to check for FEATURE_TOUCHSCREEN
