Question

我想在spinner选中的项目中创建alertDialog，并在alertDialog中添加EditText。感谢

        sh = (Spinner) view.findViewById(R.id.shield);
    ArrayAdapter<CharSequence> adaptera = ArrayAdapter.createFromResource(getActivity(),
            R.array.shield, android.R.layout.simple_spinner_item);
    adaptera.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    sh.setAdapter(adaptera);



    sh.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            sa = (String) sh.getSelectedItem();
            AlertDialog.Builder alertDialogBuildera = new AlertDialog.Builder(getActivity());
            alertDialogBuildera.setTitle("Your Title");
            alertDialogBuildera
                    .setMessage("Click yes to exit!")
                    .setCancelable(false)
                    .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int id) {
                            double sl = Double.valueOf(tc.getText().toString());
                                            getActivity().finish();
                        }
                    })
                    .setNegativeButton("No", new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int id) {
                            dialog.cancel();
                        }
                    });
            AlertDialog alertDialoga = alertDialogBuildera.create();
            if (sa.trim().equals("Lead")) {
                alertDialoga.show();
            } else
            if (sa.trim().equals("Steel")) {
                alertDialoga.show();
            }
        }
    });

它不起作用。如果我选择了项目，则会自动显示alertdialog。
