Android监听蓝牙耳机的按键事件
一、本文测试环境：
1、使用Dacom M10蓝牙耳机
2、成功监测到“电话键”(音量键没有监测到)
3、参考资料
4、参考源码
二、一些说明
连接蓝牙耳机后，需打开如图所示的两个选项。
二、代码实现
@Overridepublic boolean onKeyDown(int keyCode, KeyEvent event) {printToast(parseKeyCode(keyCode));return true;}public String parseKeyCode(int keyCode) {String ret = "";switch (keyCode) {case KeyEvent.KEYCODE_POWER:// 监控/拦截/屏蔽电源键 这里拦截不了ret = "get Key KEYCODE_POWER(KeyCode:" + keyCode + ")";break;case KeyEvent.KEYCODE_RIGHT_BRACKET:// 监控/拦截/屏蔽返回键ret = "get Key KEYCODE_RIGHT_BRACKET";break;case KeyEvent.KEYCODE_MENU:// 监控/拦截菜单键ret = "get Key KEYCODE_MENU";break;case KeyEvent.KEYCODE_HOME:// 由于Home键为系统键，此处不能捕获ret = "get Key KEYCODE_HOME";break;case KeyEvent.KEYCODE_DPAD_UP:// 监控/拦截/屏蔽上方向键ret = "get Key KEYCODE_DPAD_UP";break;case KeyEvent.KEYCODE_DPAD_LEFT:// 监控/拦截/屏蔽左方向键ret = "get Key KEYCODE_DPAD_LEFT";break;case KeyEvent.KEYCODE_DPAD_RIGHT:// 监控/拦截/屏蔽右方向键ret = "get Key KEYCODE_DPAD_RIGHT";break;case KeyEvent.KEYCODE_DPAD_DOWN:// 监控/拦截/屏蔽下方向键ret = "get Key KEYCODE_DPAD_DOWN";break;case KeyEvent.KEYCODE_DPAD_CENTER:// 监控/拦截/屏蔽中方向键ret = "get Key KEYCODE_DPAD_CENTER";break;case KeyEvent.FLAG_KEEP_TOUCH_MODE:// 监控/拦截/屏蔽长按ret = "get Key FLAG_KEEP_TOUCH_MODE";break;case KeyEvent.KEYCODE_VOLUME_DOWN:// 监控/拦截/屏蔽下方向键ret = "get Key KEYCODE_VOLUME_DOWN(KeyCode:" + keyCode + ")";break;case KeyEvent.KEYCODE_VOLUME_UP:// 监控/拦截/屏蔽中方向键ret = "get Key KEYCODE_VOLUME_UP(KeyCode:" + keyCode + ")";break;case 220:// case KeyEvent.KEYCODE_BRIGHTNESS_DOWN:// 监控/拦截/屏蔽亮度减键ret = "get Key KEYCODE_BRIGHTNESS_DOWN(KeyCode:" + keyCode + ")";break;case 221:// case KeyEvent.KEYCODE_BRIGHTNESS_UP:// 监控/拦截/屏蔽亮度加键ret = "get Key KEYCODE_BRIGHTNESS_UP(KeyCode:" + keyCode + ")";break;case KeyEvent.KEYCODE_MEDIA_PLAY:ret = "get Key KEYCODE_MEDIA_PLAY(KeyCode:" + keyCode + ")";break;case KeyEvent.KEYCODE_MEDIA_PAUSE:ret = "get Key KEYCODE_MEDIA_PAUSE(KeyCode:" + keyCode + ")";break;case KeyEvent.KEYCODE_MEDIA_PREVIOUS:ret = "get Key KEYCODE_MEDIA_PREVIOUS(KeyCode:" + keyCode + ")";break;case KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE:ret = "get Key KEYCODE_MEDIA_PLAY_PAUSE(KeyCode:" + keyCode + ")";break;case KeyEvent.KEYCODE_MEDIA_NEXT:ret = "get Key KEYCODE_MEDIA_NEXT(KeyCode:" + keyCode + ")";break;default:ret = "keyCode: "+ keyCode+ " (http://developer.android.com/reference/android/view/KeyEvent.html)";break;}return ret;}public void printToast(String str) {tvShow.setText(str);}更多精彩资讯，请扫码关注。
