Android 我想根据选中的radiobutton传递意图值，只有在用户单击按钮后，这里才是我的代码

如何根据选中的单选按钮传递intent值，intent应仅在单击按钮后启动，并且应根据swith case语句传递值这是我的代码请帮助我

在RadioGroup按钮的OnClickListener中使用以下选项

AlertDialogBuilder voteBuilder = new AlertDialogBuilder(baseContext);

        final Context context = voteBuilder.getThemeContext();

        voteBuilder.setTitle("Vote");

        LayoutInflater inflater = voteBuilder.getLayoutInflater();

        View viewVote = inflater.inflate(R.layout.eip_vote_popup, null, false);

        TextView qsnText = (TextView) viewVote.findViewById(R.id.textPollingQuestion);
        qsnText.setText(description + "?");

        final RadioButton radioPositive = (RadioButton) viewVote.findViewById(R.id.radioPositive);
        final RadioButton radioNegative = (RadioButton) viewVote.findViewById(R.id.radioNegative);

        if (pollType.equals("AD")) {
            radioPositive.setText("Agree");
            radioNegative.setText("Disagree");
        } else {
            radioPositive.setText("Yes");
            radioNegative.setText("No");
        }

        voteBuilder.setView(viewVote);

        voteBuilder.setNegativeButton("Cancel", null);
        voteBuilder.setPositiveButton("Vote", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {

            }
        });
        voteBuilder.setCancelable(true);

        final AlertDialog dialog = voteBuilder.show();
        dialog.setCanceledOnTouchOutside(true);

        dialog.getButton(AlertDialog.BUTTON_POSITIVE).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                if (!radioPositive.isChecked() && !radioNegative.isChecked()) {
                    Toast.makeText(context, "Select your opinion", Toast.LENGTH_SHORT).show();
                    return;
                }

                //EIPService service = new EIPService(context);
                //service.SaveUserPoll(pollingId, radioPositive.isChecked());
                dialog.dismiss();
            }
        });

您调用的不是服务，而是必要的意图。不要使用切换情况，有时会出现问题。

将意向实例设置为全局，然后单击按钮将该对象传递给

startActivity（Intent）
