类名称：Input

Input介绍

[英]Interface to the input facilities. This allows polling the state of the keyboard, the touch screen and the accelerometer. On some backends (desktop, gwt, etc) the touch screen is replaced by mouse input. The accelerometer is of course not available on all backends.

Instead of polling for events, one can process all input events with an InputProcessor. You can set the InputProcessor via the #setInputProcessor(InputProcessor) method. It will be called before the ApplicationListener#render()method in each frame.

Keyboard keys are translated to the constants in Keys transparently on all systems. Do not use system specific key constants.

The class also offers methods to use (and test for the presence of) other input systems like vibration, compass, on-screen keyboards, and cursor capture. Support for simple input dialogs is also provided.
[中]与输入设备的接口。这允许轮询键盘、触摸屏和加速计的状态。在某些后端（桌面、gwt等），触摸屏被鼠标输入取代。当然，加速计并非在所有后端都可用。
可以使用InputProcessor处理所有输入事件，而不是轮询事件。您可以通过#setInputProcessor（InputProcessor）方法设置InputProcessor。它将在每个帧中的ApplicationListener#render（）方法之前调用。
在所有系统上，键盘键都透明地转换为键中的常量。不要使用系统特定的键常量。
该课程还提供了使用（和测试是否存在）其他输入系统的方法，如振动、指南针、屏幕键盘和光标捕捉。还提供了对简单输入对话框的支持。
