安卓锁屏

android强制锁屏代码,Android监听锁屏、解锁、开屏功能代码

1、⾸先定义ScreenListener

;

astReceiver;

t;

;

Filter;

anager;

/**

*Createdby${zyj}on2016/6/21.

*/

publicclassScreenListener{

privateContextmContext;

privateScreenBroadcastReceivermScreenReceiver;

privateScreenStateListenermScreenStateListener;

publicScreenListener(Contextcontext){

mContext=context;

mScreenReceiver=newScreenBroadcastReceiver();

}

/**

*screen状态⼴播接收者

*/

privateclassScreenBroadcastReceiverextendsBroadcastReceiver{

privateStringaction=null;

@Override

publicvoidonReceive(Contextcontext,Intentintent){

action=ion();

if(_SCREEN_(action)){//开屏

enOn();

}elif(_SCREEN_(action)){//锁屏

enOff();

}elif(_USER_(action)){//解锁

Prent();

}

}

}

/**

*开始监听screen状态

*

*@paramlistener

*/

publicvoidbegin(ScreenStateListenerlistener){

mScreenStateListener=listener;

registerListener();

getScreenState();

}

/**

*获取screen状态

*/

privatevoidgetScreenState(){

PowerManagermanager=(PowerManager)mContext

.getSystemService(_SERVICE);

if(enOn()){

if(mScreenStateListener!=null){

enOn();

}

}el{

if(mScreenStateListener!=null){

enOff();

}

}

}

/**

*停⽌screen状态监听

*/

publicvoidunregisterListener(){

sterReceiver(mScreenReceiver);

}

/**

*启动screen状态⼴播接收器

*/

privatevoidregisterListener(){

IntentFilterfilter=newIntentFilter();

ion(_SCREEN_ON);

ion(_SCREEN_OFF);

ion(_USER_PRESENT);

erReceiver(mScreenReceiver,filter);

}

publicinterfaceScreenStateListener{//返回给调⽤者屏幕状态信息

publicvoidonScreenOn();

publicvoidonScreenOff();

publicvoidonUrPrent();

}

}

2、使⽤

;

patActivity;

;

;

publicclassMainActivityextendsAppCompatActivity{

privateScreenListenerscreenListener;

@Override

protectedvoidonCreate(BundlesavedInstanceState){

te(savedInstanceState);

tContentView(ty_main);

screenListener=newScreenListener();

(StateListener(){

@Override

publicvoidonScreenOn(){

xt(,"屏幕打开了",_SHORT).show();

}

@Override

publicvoidonScreenOff(){

xt(,"屏幕关闭了",_SHORT).show();

}

@Override

publicvoidonUrPrent(){

xt(,"解锁了",_SHORT).show();

}

});

}

}
