我使用了獲取網絡status.I廣播接收器時,從另一個類的變量正在使用此代碼訪問使用廣播接收機
public class ConnectionChangeReceiver extends BroadcastReceiver
{
public Boolean networkStatus=false;
@Override
public void onReceive(Context context, Intent intent)
{
ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetInfo = connectivityManager.getActiveNetworkInfo();
NetworkInfo mobNetInfo = connectivityManager.getNetworkInfo( ConnectivityManager.TYPE_MOBILE);
Log.w("Network Status:",""+activeNetInfo);
if (activeNetInfo != null)
{
networkStatus=true;
Toast.makeText(context, "Active Network Type : " + activeNetInfo.getTypeName(), Toast.LENGTH_SHORT).show();
}
if(mobNetInfo != null)
{
networkStatus=true;
Toast.makeText(context, "Mobile Network Type : " + mobNetInfo.getTypeName(), Toast.LENGTH_SHORT).show();
}
}
但是你知道這是另一個類,我要訪問networkStatus
變量來自主要活動班。我可以怎樣做?
製作'static'變量並在'BroadcastReceiver'中訪問它....它有什麼問題? – 2014-09-24 10:16:36
您可以將其設爲公共靜態或通過sharedpreferences保存/檢索它 – santalu 2014-09-24 10:17:26
