MTK 自定义按键添加广播

一、给自定义按键添加广播

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");
 
 
     
    //添加自定义按键广播----开始
    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;
      }
       
      //添加自定义按键广播----结束

        // myron add robot wakeup key
        if (keyCode == 0) {
            Intent myronIntent = new Intent();
            if(down) {
                myronIntent.setAction("com.yxrobot.KEY_DOWN");
            } else {
                myronIntent.setAction("com.yxrobo.KEY_UP")
            }
            myronIntent.putExtra("keycode", keycode);
            mContext.sendBroadcastAsUser(myronIntent, UserHandle, ALL);
        }
