大佬教程收集整理的这篇文章主要介绍了如何获取android中的屏幕锁定广播，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
public void onReceive(Context context,Intent intent) { Log.d("XYZ","Screen ON/OFF"); Toast.makeText(context,"screen",10000).show(); if(intent.getAction().equals(Intent.ACTION_SCREEN_ON)) { ....... } }
在活动中,我已注册广播,如 –
屏幕是我的广播接收器的对象
IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON); filter.addAction(Intent.ACTION_SCREEN_OFF); mContext.registerReceiver(screen,filter);
startservice(new Intent(MainActivity.this,updateservice.class));
public class updateservice extends service { BroadcastReceiver mReceiver; public static int countOn = 0; public static int countOff = 0; @Override public void onCreate() { super.onCreate(); // register receiver that handles screen on and screen off logic Log.i("updateservice","Started"); IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON); filter.addAction(Intent.ACTION_SCREEN_OFF); filter.addAction(Intent.ACTION_ANSWER); mReceiver = new MyReceiver(); registerReceiver(mReceiver,filter); } @Override public void onDestroy() { unregisterReceiver(mReceiver); Log.i("onDestroy Reciever","Called"); super.onDestroy(); } @Override public int onStartCommand(Intent intent,int flags,int startId) { // TODO Auto-generated method stub Boolean screenOn = intent.getBooleanExtra("screen_state",falsE); if (!screenOn) { Log.i("screenON","Called"); Log.i("viaservice","CountOn =" + countOn); Toast.makeText(getApplicationContext(),"Awake",Toast.LENGTH_LONG) .show(); } else { Log.i("screenOFF","CountOff =" + countOff); } return START_STICKY; } @Override public IBinder onBind(Intent intent) { // TODO Auto-generated method stub return null; } }
接收器类
public class MyReceiver extends BroadcastReceiver { private Boolean screenOff; @Override public void onReceive(Context context,Intent intent) { if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) { screenOff = true; // Log.i("via Receiver","Normal ScreenOFF" ); } else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) { screenOff = false; } else if(intent.getAction().equals(Intent.ACTION_ANSWER)) { } Intent i = new Intent(context,updateservice.class); i.putExtra("screen_state",screenOff); context.startservice(i); } }
