Android Judgment Screen Switch State mode summary _android

Android Judge screen switch status

Method one: Using System services

PowerManager pm= (PowerManager) Mcontext.getsystemservice (context.power_service);

    if (!pm.isscreenon ())
    {
      //quenching State
    }

Method Two: Use broadcast

The public class Screenreceiver extends Broadcastreceiver {




  @Override
  the public void onreceive Intent Intent) {




    if (intent.getaction (). Equals (Intent.action_screen_off)) {
      
//Receive a screen broadcast

    } else if ( Intent.getaction (). Equals (intent.action_screen_on)) {

//Receive quenching broadcast

    }}


  }
  

Registered broadcast
Screenreceiver sonbroadcastreciver=new screenreceiver ();
    Intentfilter recevierfilter=new intentfilter ();
    Recevierfilter.addaction (intent.action_screen_on);
    Recevierfilter.addaction (Intent.action_screen_off);
    Registerreceiver (Sonbroadcastreciver, recevierfilter);


Unregister
if (sonbroadcastreciver!=null)
    {
      unregisterreceiver (sonbroadcastreciver);
    }

Note: Both the screen and the quenching broadcast can only be received by dynamic registration.
