一、給自定義按鍵添加廣播

修改PhoneWindowManager.java中的interceptKeyBeforeDispatching方法

/frameworks/base/policy/src/com/android/internal/policy/impl/PhoneWindowManager.java

@Override

public long interceptKeyBeforeDispatching(WindowState win, KeyEvent event, int policyFlags) {

final boolean keyguardOn = keyguardOn();

final int keyCode = event.getKeyCode();

final int repeatCount = event.getRepeatCount();

final int metaState = event.getMetaState();

final int flags = event.getFlags();

final boolean down = event.getAction() == KeyEvent.ACTION_DOWN;

final boolean canceled = event.isCanceled();

final boolean longPress = (flags & KeyEvent.FLAG_LONG_PRESS) != 0;

final boolean virtualKey = event.getDeviceId() == KeyCharacterMap.VIRTUAL_KEYBOARD;

final String isCitKeyTest=SystemProperties.get("persist.sys.startCitKeyTest");

//添加自定義按鍵廣播----開始

switch (keyCode)

{

case 135:

case 136:

case 137:

case 139:

{

if (repeatCount == 0) {

Intent myKeyIntent = new Intent();

if(down)

{

myKeyIntent.setAction("com.rscja.android.KEY_DOWN");

}

else

{

myKeyIntent.setAction("com.rscja.android.KEY_UP");

}

myKeyIntent.putExtra("keycode", keyCode);

mContext.sendBroadcastAsUser(myKeyIntent, UserHandle.ALL);

}

}

break;

}

//添加自定義按鍵廣播----結束

}

二、通過廣播給當前焦點輸入框賦值

修改InputMethodService.java中的onCreate()方法

/frameworks/base/core/java/android/inputmethodservice/InputMethodService.java
