protectedvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.button_layuout);
finalIntentFilterfilter=newIntentFilter();
//屏幕灭屏广播
filter.addAction(Intent.ACTION_SCREEN_OFF);
//屏幕亮屏广播
filter.addAction(Intent.ACTION_SCREEN_ON);
//屏幕解锁广播
filter.addAction(Intent.ACTION_USER_PRESENT);
//当长按电源键弹出“关机”对话或者锁屏时系统会发出这个广播
//example：有时候会用到系统对话框，权限可能很高，会覆盖在锁屏界面或者“关机”对话框之上，
//所以监听这个广播，当收到时就隐藏自己的对话，如点击pad右下角部分弹出的对话框
