Question

我正在尝试在警告对话框中添加自定义单选按钮。现在我想添加监听器。我试图使用Radio组添加侦听器，但它显示空指针异常。这是我的代码。请如何添加监听器，我想在点击任何单选按钮

时关闭对话框

    final AlertDialog.Builder alt_bld = new AlertDialog.Builder(this);
    LayoutInflater eulaInflater = LayoutInflater.from(this);
    View eulaLayout = eulaInflater.inflate(R.layout.alertdialogcustom, null);
    alt_bld.setView(eulaLayout);
    RadioGroup rgroup = (RadioGroup)findViewById(R.id.group1);

我自己使用Dialog

得到它

     dialog.setContentView(R.layout.alertdialogcustom);
     dialog.setTitle("This is my custom dialog box");
     dialog.setCancelable(true);

     final RadioGroup rgroup = (RadioGroup)dialog.findViewById(R.id.group1);
     final RadioButton rbutton_series = (RadioButton) dialog.findViewById(R.id.option1);
     final RadioButton rbutton_overlay = (RadioButton) dialog.findViewById(R.id.option2);
    rgroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener()
