Android如何键盘按键响应事件_安卓息屏如何拿到键盘的按压的值

测试代码及其说明如下：

/**
		 * Use with setDefaultKeyMode to launch the dialer during default key
		 * handling 将键盘所有的按键传递到拨号
		 */
		setDefaultKeyMode(DEFAULT_KEYS_DIALER);
		/**
		 * Use with setDefaultKeyMode to turn off default handling of keys.
		 * 直接丢弃，这种情况你把键盘按穿了也不会有系统理你
		 */
		setDefaultKeyMode(DEFAULT_KEYS_DISABLE);
		/**
		 * Use with setDefaultKeyMode to specify that unhandled keystrokes will
		 * start a global search (typically web search, but some platforms may
		 * define alternate methods for global search) 将键盘输入作为搜索内容，进行全局搜索
		 * 保证当前处于英文输入模式，可以通过呼出一个软键盘来改变当前输入模式。
		 */
		setDefaultKeyMode(DEFAULT_KEYS_SEARCH_GLOBAL);
		/**
		 * Use with setDefaultKeyMode to specify that unhandled keystrokes will
		 * start an application-defined search. (If the application or activity
		 * does not actually define a search, the the keys will be ignored.)
		 * 将键盘输入作为搜索内容，进行本地搜索，如果本地没有实现自定义搜索，则会被忽略.
		 */
		setDefaultKeyMode(DEFAULT_KEYS_SEARCH_LOCAL);
		/**
		 * Use with setDefaultKeyMode to execute a menu shortcut in default key
		 * handling. That is, the user does not need to hold down the menu key to execute
		 * menu shortcuts.
		 * 将键盘输入作为当前窗体上注册的快捷键，进行快捷键处理
		 */
		setDefaultKeyMode(DEFAULT_KEYS_SHORTCUT);
