Android 监听屏幕唤醒和关闭的广播

亦余心之所善兮,虽九死其犹未悔。这篇文章主要讲述Android 监听屏幕唤醒和关闭的广播相关的知识,希望能为你提供帮助。
  今天希望应用程序的服务运行时,可以监听到屏幕的唤醒。继续百度学习法,连同监听闭幕关闭也一同学习了。
 
此种情况需要动态注册系统广播。在androidManifest.xml中静态注册的实际运行中无效。
 

private ScreenStatusReceiver mScreenStatusReceiver;

 
在需要的地方调用如下函数:
private void registSreenStatusReceiver() { mScreenStatusReceiver = new ScreenStatusReceiver(); IntentFilter screenStatusIF = new IntentFilter(); screenStatusIF.addAction(Intent.ACTION_SCREEN_ON); screenStatusIF.addAction(Intent.ACTION_SCREEN_OFF); registerReceiver(mScreenStatusReceiver, screenStatusIF); }

 
使用结束后,注销:
unregisterReceiver(mScreenStatusReceiver);

 
ScreenStatusReceiver类:
class ScreenStatusReceiver extends BroadcastReceiver { String SCREEN_ON = "android.intent.action.SCREEN_ON"; String SCREEN_OFF = "android.intent.action.SCREEN_OFF"; @Override public void onReceive(Context context, Intent intent) { if (SCREEN_ON.equals(intent.getAction())) { Log.w("ppp","ppp-屏幕亮了"); } else if (SCREEN_OFF.equals(intent.getAction())) {
Log.w("ppp","ppp-屏幕暗了"); } } }
