Android 监听屏幕唤醒和关闭的广播

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");

            }

        }

    }
