我有一个包含两个 RadioButtons 的 RadioGroup 的自定义对话框。选择的 RadioButton 确定要设置的字符串。当我做

 Toast.makeText(NewFile.this, checkedId, Toast.LENGTH_LONG)
                            .show();

无论选择哪个 RadioButton，它都会将 checkedId 显示为 false，并且只有第二种情况将 String 设置为正确的值。以下是我目前的代码：

AlertDialog.Builder customDialog = new AlertDialog.Builder(NewFile.this);
        LayoutInflater layoutInflater = (LayoutInflater) getApplicationContext()
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View view = layoutInflater.inflate(R.layout.jquery_dialog, null);
        final EditText idTxt = (EditText) view.findViewById(R.id.idName);
        final CheckBox headerChk = (CheckBox) view.findViewById(R.id.headerChk);
        final CheckBox footerChk = (CheckBox) view.findViewById(R.id.footerChk);
        final RadioGroup group = (RadioGroup) view
                .findViewById(R.id.jqmNavigation);
        customDialog.setView(idTxt);
        customDialog.setView(headerChk);
        customDialog.setView(footerChk);
        group.setOnCheckedChangeListener(new OnCheckedChangeListener() {

            @Override
            public void onCheckedChanged(RadioGroup group, int checkedId) {

                switch (checkedId) {
                case R.id.ol: // First RadioButton
                    Toast.makeText(NewFile.this, checkedId, Toast.LENGTH_LONG)
                            .show();
                    jqMobNavbar = "<div data-role=\"navbar\">\n" + "        <ol>\n"
                            + "         <li><a href=\"#\">Page 1</a></li>\n"
                            + "         <li><a href=\"#\">Page 2</a></li>\n"
                            + "         <li><a href=\"#\">Page 3</a></li>\n"
                            + "     <ol>\n" + " </div>\n";
                    break;
                case R.id.ul: // Second RadioButton
                    Toast.makeText(NewFile.this, checkedId, Toast.LENGTH_LONG)
                            .show();
                    jqMobNavbar = "<div data-role=\"navbar\">\n" + "        <ul>\n"
                            + "         <li><a href=\"#\">Page 1</a></li>\n"
                            + "         <li><a href=\"#\">Page 2</a></li>\n"
                            + "         <li><a href=\"#\">Page 3</a></li>\n"
                            + "     <ul>\n" + " </div>\n";
                    break;

                }

            }
        });

    </RadioGroup>

</LinearLayout>

我也试过

group.setOnCheckedChangeListener(new OnCheckedChangeListener() {

            @Override
            public void onCheckedChanged(RadioGroup group, int checkedId) {
                int radioButtonID = group.getCheckedRadioButtonId();
                View radioButton = group.findViewById(radioButtonID);
                int idx = group.indexOfChild(radioButton);
                switch (idx) {
                case 1:
                    Toast.makeText(NewFile.this, checkedId, Toast.LENGTH_LONG)
                            .show();
                    jqMobNavbar = "<div data-role=\"navbar\">\n" + "        <ol>\n"
                            + "         <li><a href=\"#\">Page 1</a></li>\n"
                            + "         <li><a href=\"#\">Page 2</a></li>\n"
                            + "         <li><a href=\"#\">Page 3</a></li>\n"
                            + "     <ol>\n" + " </div>\n";
                    break;
                case 2:
                    Toast.makeText(NewFile.this, checkedId, Toast.LENGTH_LONG)
                            .show();
                    jqMobNavbar = "<div data-role=\"navbar\">\n" + "        <ul>\n"
                            + "         <li><a href=\"#\">Page 1</a></li>\n"
                            + "         <li><a href=\"#\">Page 2</a></li>\n"
                            + "         <li><a href=\"#\">Page 3</a></li>\n"
                            + "     <ul>\n" + " </div>\n";
                    break;

                }

            }
        });

检查所选 RadioButton 值的正确方法是什么？

你是什​​么意思checkedId是假的？这是一个整数，不能为假。如果您的任何一个 case 语句都有效，这意味着 checkedId 是它应该是的 id 值。

如果您将第一个 RadioButton 设置为在 XML 中选中，则在按下另一个按钮之前不会调用您的任何案例。或者，您也可以 在每个按钮上设置：http: //developer.android.com/reference/android/widget/CompoundButton.OnCheckedChangeListener.html 。

它返回false是因为它是一个Integer. 尝试使用：

Toast.makeText(getApplicationContext(), Integer.toString(checkedId), Toast.LENGTH_SHORT).show();
