我有一个广播组,其中我有2个单选按钮

现在,如果选择单选按钮1,如果我点击相同的单选按钮(单选按钮1),则应该取消选中它.

它应该像切换一样工作.

使用以下方法以编程方式在警报框中显示单选按钮

 Private void SelectLanguageMethod(){


    // Strings to Show In Dialog with Radio Buttons
            final CharSequence[] items = {"English"," Spanish "};

            // Creating and Building the Dialog
            final AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setTitle("Select The Language");
            builder.setSingleChoiceItems(items, -1, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int item) {

            //Your code here

         }
            });
            levelDialog = builder.create();
            levelDialog.show();
        }
