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"); } } }
