android升级后WIFI信号强度显示的问题

Question

获得信号强度，在android源码里面
在package/apps/Settings code里面，RadioInfo.java
  int signalDbm = mPhoneStateReceiver.getSignalStrengthDbm();  if (-1 == signalDbm) signalDbm = 0;  int signalAsu = mPhoneStateReceiver.getSignalStrength();  if (-1 == signalAsu) signalAsu = 0;

Answer 1

frameworks/base/services/java/com/android/server/status/StatusBarPolicy.java这个文件里面应该有你想要的，
private BroadcastReceiver mIntentReceiver = new BroadcastReceiver() {
   @Override
        public void onReceive(Context context, Intent intent) {
              ......
              else if (action.equals(WifiManager.NETWORK_STATE_CHANGED_ACTION) ||
                    action.equals(WifiManager.WIFI_STATE_CHANGED_ACTION) ||
                    action.equals(WifiManager.RSSI_CHANGED_ACTION)) {
                        updateWifi(intent);
               }
               ......
            }
    }
}
