1.确认驱动中的键值定义
kernel-3.18/include/uapi/linux/input.h
#define KEY_F13 183
驱动中会上报KEY_F13,对应键值就是183,驱动上报的键值android层会映射成android Keycode
2.*.kl文件中添加键值
/frameworks/base/data/keyboards/Generic.kl
key 183 F13
/frameworks/base/data/keyboards/qwerty.kl
key 183 F13
3.定义键值映射
/frameworks/native/include/input/InputEventLabels.h
数组中添加
static const InputEventLabel KEYCODES[] = {
…..
DEFINE_KEYCODE(F13),
}
/frameworks/native/include/android/keycodes.h
enum {
….
AKEYCODE_F13 = 280
}
4.
/frameworks/base/core/java/android/view/KeyEvent.java
public class KeyEvent extends InputEvent implements Parcelable {
……
public static final int KEYCODE_F13 = 280;
}
/frameworks/base/core/res/res/values/attrs.xml
<enum name=”KEYCODE_F13″ value=”280″/>
5.mtk中的定义(current.txt)(根据具体项目添加)
frameworks/base/api/current.txt
field public static final int KEYCODE_F13 = 266;
