如果我们在 wifi 上，如何更新小部件

Question

我制作了一个小部件来检测连接是否为wifi问题是它仅在小部件启动时才检测到我，而我希望它在连接更改后立即检测到它，我进行了广播，但感觉它只工作一次当我希望它一直在听的时候

附上代码

    @Override
public void onReceive(Context context, Intent intent) {


    WifiManager wifiManager = (WifiManager)context.getApplicationContext().getSystemService(Context.WIFI_SERVICE);
    int state = wifiManager.getWifiState();
    String statusInfo = "Unknown";
    AppWidgetManager appWidgetManager = AppWidgetManager
            .getInstance(context);
    RemoteViews nom = new RemoteViews(context.getPackageName(),R.layout.testwidget);
    switch (state)  {

        case WifiManager.WIFI_STATE_DISABLED:
            statusInfo = "Disabled";

            nom.setTextViewText(R.id.textView, "Data");
            appWidgetManager.updateAppWidget(new ComponentName(context,
                    testwidget.class),nom);
            break;

        case WifiManager.WIFI_STATE_ENABLED:
            statusInfo = "Enabled";
            nom.setTextViewText(R.id.textView, "Wifi");
            appWidgetManager.updateAppWidget(new ComponentName(context,
                    testwidget.class),nom);
            break;

    }
}

我的清单

 <uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
