推荐答案

问题已解决.

在我们调用alert.show的地方初始化builder.create

Problem Solved.

Initialize the builder.create in the place where we call alert.show

var alertDialog:AlertDialog? = null
override fun onReceive(context: Context, arg1: Intent) {
    var dialogBuilder = AlertDialog.Builder(context).setTitle("Network Error !")
            .setCancelable(false)
            .setMessage("Check your internet connection...")

    if (isConnectedOrConnecting(context)) {
        //initializeDialog(context)
        alertDialog!!.dismiss()
        Log.i("Network","Alive")
    }else{
        alertDialog = dialogBuilder.create()
        alertDialog!!.show()
        Log.i("Network","Dead")
        //initializeDialog(context).create()
    }
}
