去掉长按遥控器power键后提示关机、飞行模式的弹窗

首先找到对应长短按power键的位置：

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

java 复制代码

private final Runnable mPowerLongPress = new Runnable() {
        @Override
        public void run() {
            // The context isn't read
            if (mLongPressOnPowerBehavior < 0) {
                mLongPressOnPowerBehavior = mContext.getResources().getInteger(
                        com.android.internal.R.integer.config_longPressOnPowerBehavior);
            }
            int resolvedBehavior = mLongPressOnPowerBehavior;
            if (FactoryTest.isLongPressOnPowerOffEnabled()) {
                resolvedBehavior = LONG_PRESS_POWER_SHUT_OFF_NO_CONFIRM;
            }
            switch (resolvedBehavior) {
            case LONG_PRESS_POWER_NOTHING:
                break;
            case LONG_PRESS_POWER_GLOBAL_ACTIONS:
                mPowerKeyHandled = true;
                //<!-- $_rbox_$_modify_$_huangjc -->
                if("true".equals(SystemProperties.get("persist.sys.realsleep"))){
                   showSleepDialog();
                } else {
                if (!performHapticFeedbackLw(null, HapticFeedbackConstants.LONG_PRESS, false)) {
                    performAuditoryFeedbackForAccessibilityIfNeed();
                }
                sendCloseSystemWindows(SYSTEM_DIALOG_REASON_GLOBAL_ACTIONS);
                showGlobalActionsDialog();
                }
                break;
            case LONG_PRESS_POWER_SHUT_OFF:
            case LONG_PRESS_POWER_SHUT_OFF_NO_CONFIRM:
                mPowerKeyHandled = true;
                performHapticFeedbackLw(null, HapticFeedbackConstants.LONG_PRESS, false);
                sendCloseSystemWindows(SYSTEM_DIALOG_REASON_GLOBAL_ACTIONS);
                mWindowManagerFuncs.shutdown(resolvedBehavior == LONG_PRESS_POWER_SHUT_OFF);
                break;
            }
        }
    };

其中case LONG_PRESS_POWER_GLOBAL_ACTIONS: 对应的是长按，而调用的方法showGlobalActionsDialog()就是处理弹窗的方法；

java 复制代码

   void showGlobalActionsDialog() {
        if (mGlobalActions == null) {
            mGlobalActions = new GlobalActions(mContext, mWindowManagerFuncs);
        }
        final boolean keyguardShowing = keyguardIsShowingTq();
        mGlobalActions.showDialog(keyguardShowing, isDeviceProvisioned());
        if (keyguardShowing) {
            // since it took two seconds of long press to bring this up,
            // poke the wake lock so they have some time to see the dialog.
            mPowerManager.userActivity(SystemClock.uptimeMillis(), false);
        }
    }

所以去掉showGlobalActionsDialog();就不会再有弹窗出现了；

如果要做短按power键使系统直接关机的这个功能，那么只需要在PhoneWindowManager.java中找到短按处理的代码，然后添加mWindowManagerFuncs.shutdown(true);就可以了。
