從 API 16 開始, InputManager就成了一個公開的類別了, 可以通過如下方法獲得 InputManager:
InputManager im = (InputManager) getSystemService(Context.INPUT_SERVICE);
...
private synchronized void injectKeyEvent(KeyEvent event) {
Class[] paramTypes = new Class[2];
paramTypes[0] = InputEvent.class;
paramTypes[1] = Integer.TYPE;
InputManager im = (InputManager) getSystemService(Context.INPUT_SERVICE);
Object[] params = new Object[2];
params[0] = event;
params[1] = 0;
try {
Method injectKeyEvent = im.getClass().getMethod("injectInputEvent", paramTypes);
injectKeyEvent.invoke(im, params);
} catch (NoSuchMethodException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
...
INJECT_EVENTS

注意, 使用 injectInputEvent() 需要申明
android:name="android.permission.INJECT_EVENTS" 權限.
你可能還需要 system uid
android:sharedUserId="android.uid.system"

Fire Positive or Negative KeyCodes

public void onNative(int action, int keycode) {
event = new KeyEvent(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), action, keycode, 0);
injectKeyEvent(event);
}
...
Android 可以發射 (fire) 負的 KeyCodes; 它的 KeyCodes 是 32-bit integer (注意: 非 unsigned integer) ; 如果以 KeyCode MSB (Most Significant Bit) set/reset 來區分第1組與第2組設備, 以 KEYCODE_BUTTON_Z 為例, 則:
第1組: KEYCODE_BUTTON_Z
第2組: (KEYCODE_BUTTON_Z - 0x7fffffff - 1)
// JNI .cpp
...
if ((events & (1ULL <<codes[i].index)) != (lastEvents & (1ULL <<codes[i].index))) {
if ((events & (1ULL <<codes[i].index)) == (1ULL <<codes[i].index)) {
PortTwoEnv->CallVoidMethod(nativeObj, cachedmethodID, ACTION_UP, codes[i].code);
}
else {
PortTwoEnv->CallVoidMethod(nativeObj, cachedmethodID, ACTION_DOWN, codes[i].code);
};
}
...
...
// ACTIVITY .java
public class MainActivity extends Activity {
...
public boolean onKeyDown(int KeyCode, KeyEvent E) {
...
switch (KeyCode) {
case (KEYCODE_BUTTON_Z - 0x7fffffff - 1):
... //第2組
return true;
case KeyEvent.KEYCODE_BUTTON_Z:
... //第1組
return true;
}
return false;

/*
This routine is used for receive the uart specific characters and fire input key events accordingly.
So if this routine is used, the serial console must be disabled.
I. how to disable serial console?
1. In dts: bootargs = "mem=16M init=/sbin/init root=/dev/mtdblock3";
2. Mask the "ttyMk0" in target /etc/inittab
3. Add the following in target /etc/rc.local
if [ -x /usr/bin/fireUartKeys ]; then
/usr/bin/fireUartKeys &
fi
II. how to compile?
arm-linux-gnueabi-g++ fireUartKeys.cpp -o fireUartKeys -lpthread
