无法调用类android

Question

我有使用onClickListener的代码，我试图调用类NetCheck，但是像http://prntscr.com/blgi94这样的错误。当我尝试将类NetCheck放在外部onClickListener时，在此行http://prntscr.com/blginf中获取错误。我不知道如何解决它。有人可以帮帮我吗？

我的代码

premi.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg0) {
            // get prompts.xml view
            LayoutInflater li = LayoutInflater.from(context);
            View promptsView = li.inflate(R.layout.update, null);
            AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
                    context);
            // set prompts.xml to alertdialog builder
            alertDialogBuilder.setView(promptsView);
            final EditText userInput = (EditText) promptsView
                    .findViewById(R.id.editTextDialogUserInput);
            userInput.setText(cash.getText());
            // set dialog message
            alertDialogBuilder
                    .setCancelable(false)
                    .setPositiveButton("OK",
                            new DialogInterface.OnClickListener() {

                                    // get user input and set it to result
                                    // edit text
