Android ScreenLockReceiver监听锁屏功能示例
本文实例讲述了AndroidScreenLockReceiver监听锁屏功能。分享给大家供大家参考，具体如下：
监听屏幕锁屏状态（注册接受者--执行业务--注销接受者）
publicclassAppLockServiceextendsService{
privateActivityManageram;
privateKeyguardManagerkeyguardManager;
privateLockScreenReceiverreceiver;
@Override
publicvoidonCreate(){
//TODOAuto-generatedmethodstub
super.onCreate();
am=(ActivityManager)getSystemService(Context.ACTIVITY_SERVICE);
keyguardManager=(KeyguardManager)getSystemService(Context.KEYGUARD_SERVICE);
//注册锁屏广播接收者
IntentFilterfilter=newIntentFilter();
filter.addAction(Intent.ACTION_SCREEN_OFF);
receiver=newLockScreenReceiver();
registerReceiver(receiver,filter);
newThread(){
publicvoidrun(){
//一直在监听锁屏动作，一旦监听到，便执行操作
while(true){
booleanisLockScreen=keyguardManager.inKeyguardRestrictedInputMode();
/**此处可作相应操作*/
}
};
}.start();
}
privatefinalclassLockScreenReceiverextendsBroadcastReceiver{
@Override
publicvoidonReceive(Contextcontext,Intentintent){
tempAppLocks.clear();
}
}
@Override
publicvoidonDestroy(){
super.onDestroy();
//取消锁屏的广播监听
unregisterReceiver(receiver);
}
}
希望本文所述对大家Android程序设计有所帮助。
