SystemUI 中去掉锁屏

1.SystemUI 中去掉锁屏

KeyguardViewMediator @mHandler

 /**
     * This handler will be associated with the policy thread, which will also
     * be the UI thread of the keyguard.  Since the apis of the policy, and therefore
     * this class, can be called by other threads, any action that directly
     * interacts with the keyguard ui should be posted to this handler, rather
     * than called directly.
     */
    private Handler mHandler = new Handler(Looper.myLooper(), null, true /*async*/) {
        @Override
        public void handleMessage(Message msg) {
            switch (msg.what) {
                case SHOW:
                    //Do not show keyguard by ybf
                   // handleShow((Bundle) msg.obj);
                    break;
                case HIDE:
                    handleHide();
                    break;
                case RESET:
                    handleReset();
                    break;
                case VERIFY_UNLOCK:
                    Trace.beginSection("KeyguardViewMediator#handleMessage VERIFY_UNLOCK");
                    handleVerifyUnlock();
                    Trace.endSection();
                    break;
            ''''  

                    }
                    break;

2. 如果想实现自己是锁屏界面，改动越小，越能达到自己的目的，最好。

个人认为，如果能够修改SystemUI方法，那最好就是重载handleShow()方法，在这个方法中实现我们自己的锁屏界面。例如通过Activity跳转，别忘了释放PARTIAL_WEAK_LOCK。

重载这个方法，可以最大程度的不影响Android系统逻辑
