我正在尝试创建一个配置有几个文本视图、一个编辑文本、滚动视图和一个“确定”按钮的自定义对话框。由于某些原因，我无法正确对齐对话框中的“确定”按钮。

我创建对话框的代码如下：

      mLineupDialog=new Dialog(context,R.style.CustomDialogTheme);

           mLineupDialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN); 
           View view = LayoutInflater.from(context).inflate(R.layout.custom_dialog, null, false);
           rg = (RadioGroup) view.findViewById(R.id.radiogroup);
           RadioGroup.LayoutParams layoutParams = new RadioGroup.LayoutParams(
                           RadioGroup.LayoutParams.WRAP_CONTENT,
                           RadioGroup.LayoutParams.WRAP_CONTENT);

           for (int i = 0; i < lobjs.length; i++){
                   rb = new RadioButton(context);
                   rb.setText(lobjs[i].carrierName);               
                   rb.setId(i);
    //             rb.setTextColor
                   rg.addView(rb, layoutParams);
               }                  

           zipEntry.setText(mZipCode);  
           mPrefs.edit().putString(sharedZipEntry, mZipCode).commit();
     }             

       mLineupDialog.setContentView(view);            

       Button Ok =(Button)view.findViewById(R.id.lineupdialogButton);

我的布局文件如下：

        android:typeface="sans" >

        <!-- android:layout_weight="1" -->

    </Button>

</LinearLayout>

问题是“确定”按钮只是部分超出了对话框的底部边框。. 任何解决此问题的建议将不胜感激！谢谢！！
