`KeyEvent` 是Android 中用于表示按键事件的类。
每个按键都有一个唯一的键码（KeyCode），而`KeyEvent` 就用于描述这些按键事件的信息。
以下是一些常见的Android 键码及其对应的键值表：1. **数字键：**- `KeyEvent.KEYCODE_0` 到`KeyEvent.KEYCODE_9`2. **字母键：**- `KeyEvent.KEYCODE_A` 到`KeyEvent.KEYCODE_Z`3. **功能键：**- `KeyEvent.KEYCODE_F1` 到`KeyEvent.KEYCODE_F12`4. **控制键：**- `KeyEvent.KEYCODE_ENTER` - 回车键- `KeyEvent.KEYCODE_DEL` - 删除键- `KeyEvent.KEYCODE_ESCAPE` - 换码键（Esc键）- `KeyEvent.KEYCODE_TAB` - Tab键- `KeyEvent.KEYCODE_SPACE` - 空格键5. **方向键：**- `KeyEvent.KEYCODE_DPAD_UP` - 方向上键- `KeyEvent.KEYCODE_DPAD_DOWN` - 方向下键- `KeyEvent.KEYCODE_DPAD_LEFT` - 方向左键- `KeyEvent.KEYCODE_DPAD_RIGHT` - 方向右键6. **功能键：**- `KeyEvent.KEYCODE_HOME` - Home键- `KeyEvent.KEYCODE_BACK` - 返回键- `KeyEvent.KEYCODE_MENU` - 菜单键- `KeyEvent.KEYCODE_POWER` - 电源键7. **音量键：**- `KeyEvent.KEYCODE_VOLUME_UP` - 音量增加键- `KeyEvent.KEYCODE_VOLUME_DOWN` - 音量减小键8. **其他常见键：**- `KeyEvent.KEYCODE_MEDIA_PLAY` - 媒体播放键- `KeyEvent.KEYCODE_MEDIA_STOP` - 媒体停止键- `KeyEvent.KEYCODE_CAMERA` - 相机键- `KeyEvent.KEYCODE_CALL` - 拨号键- `KeyEvent.KEYCODE_ENDCALL` - 挂机键这只是一小部分可能用到的键码。

ConstantsgetAction() value: the key has been pressed down.getAction() value: multiple duplicate key events have occurred in a row, or a complex string is being delivered.getAction() value: the key has been released.When associated with up key events, this indicates that the key press has been canceled.Set when a key event has FLAG_CANCELED set because a long press action was executed while it was down.This mask is used for compatibility, to identify enter keys that are coming from an IME whose enter key has been auto-labelled "next" or "done".Set when a key event has been synthesized to implement default behavior for an event that the application did not handle.This mask is set if an event was known to come from a trusted part of the system.This mask is set if we don't want the key event to cause us to leave touch mode.This flag is set for the first key repeat that occurs after the long press timeout.This mask is set if the key event was generated by a software keyboard.Set for ACTION_UP when this event's key code is still being tracked from its initial down.This key event was generated by a virtual (on-screen) hard key area.This mask is set if the device woke because of this key event.Key code constant: '0' key.Key code constant: '1' key.Key code constant: '2' key.Key code constant: '3' key.Key code constant: 3D Mode key.Key code constant: '4' key.Key code constant: '5' key.Key code constant: '6' key.Key code constant: '7' key.Key code constant: '8' key.Key code constant: '9' key.Key code constant: 'A' key.Key code constant: Left Alt modifier key.Key code constant: Right Alt modifier key.Key code constant: ''' (apostrophe) key.Key code constant: App switch key.Key code constant: Assist key.Key code constant: '@' key.Key code constant: A/V Receiver input key.Key code constant: A/V Receiver power key.Key code constant: 'B' key.Key code constant: Back key.Key code constant: '\' key.Key code constant: Bookmark key.Key code constant: Break / Pause key.Key code constant: Generic Game Pad Button #1.Key code constant: Generic Game Pad Button #10.Key code constant: Generic Game Pad Button #11.Key code constant: Generic Game Pad Button #12.Key code constant: Generic Game Pad Button #13.Key code constant: Generic Game Pad Button #14.Key code constant: Generic Game Pad Button #15.Key code constant: Generic Game Pad Button #16.Key code constant: Generic Game Pad Button #2.
