推荐答案

您必须创建自定义对话框

Yo have to create custom dialog

import android.app.Dialog;
import android.content.Context;

public class CustomDialog extends Dialog 
{

public CustomDialog(Context context) 
{
    super(context);
    setContentView(R.layout.dialog);
}

}

创建dialog.xml文件.根据您的要求进行设计.

create dialog.xml file. design according to your requirment.
