在main.xml中

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:orientation="vertical" >

     <Button

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

</LinearLayout>

 

 

在MyDialogDemo.java程序中

package com.tarena.dialog;

 

import android.app.Activity;

import android.app.AlertDialog;

import android.app.Dialog;

import android.content.DialogInterface;

import android.os.Bundle;

import android.view.KeyEvent;

import android.view.LayoutInflater;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.ImageButton;

import android.widget.TextView;

 

public class MyDialogDemo extends Activity {

  private Button mybut = null ; // 定义按钮

  @Override

  public void onCreate(Bundle savedInstanceState) {

     super.onCreate(savedInstanceState);

     super.setContentView(R.layout.main); // 调用布局管理器

     this.mybut = (Button) super.findViewById(R.id.mybut) ;  // 取得按钮

     this.mybut.setOnClickListener(new OnClickListenerImpl()) ;  // 设置事件类

  }

  private class OnClickListenerImpl implements OnClickListener {

 

     public void onClick(View view) {

       LayoutInflater facotry = LayoutInflater.from(MyDialogDemo.this); //相当于界面的创建工厂

       View myview = facotry.inflate(R.layout.login, null);  //读取配置文件

       Dialog dialog = new AlertDialog.Builder(MyDialogDemo.this)

         .setIcon(R.drawable.ic_launcher)

         .setTitle("用户登录")

         .setPositiveButton("登录", new DialogInterface.OnClickListener() {

           

           public void onClick(DialogInterface dialog, int which) {

              }

         })

         .setNegativeButton("取消", new DialogInterface.OnClickListener() {

           public void onClick(DialogInterface dialog, int which) {

             

            }

         }).setView(myview).create() ; // 设置对话框

       dialog.show() ;

     }

    

  }

 

}
