一、Dialog布局文件

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:clickable="true"
    android:orientation="vertical"
    android:padding="20.0dip" >

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:background="#ff7200"
        android:orientation="vertical" >

        <TextView
            android:id="@+id/title"
            android:textColor="#ffffff"
            android:textSize="20sp"
            android:layout_width="fill_parent"
            android:layout_height="50dp"
            android:gravity="center"
            android:text="自定义弹窗"
            android:visibility="visible" />

        <LinearLayout
            android:id="@+id/content"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:gravity="center" >


            <TextView
                android:background="#ffffff"
                android:id="@+id/message"
                android:textColor="#b8b8b8"
                android:textSize="16sp"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:gravity="left|center"
                android:lineSpacingMultiplier="1.5"
                android:paddingBottom="15.0dip"
                android:paddingLeft="20.0dip"
                android:paddingRight="20.0dip"
                android:paddingTop="15.0dip" />
        </LinearLayout>

        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="50dp"
            android:layout_gravity="bottom"
            android:background="#ffffff"
            android:gravity="center"
            android:orientation="horizontal" >

            <TextView
                android:layout_weight="1"
                android:id="@+id/positiveTextView"
                android:textColor="#b8b8b8"
                android:textSize="16sp"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:gravity="center"
                android:text="ok"
                android:clickable="true"/>

            <TextView
                android:layout_weight="1"
                android:id="@+id/negativeTextView"
                android:textColor="#ff9138"
                android:textSize="16sp"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:gravity="center"
                android:text="cancel"
                android:clickable="true"/>
        </LinearLayout>
    </LinearLayout>

</FrameLayout>

二、Style

 <style name="Dialog" parent="android:style/Theme.Dialog">
        <item name="android:background">#00000000</item>
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowIsFloating">true</item>
    </style>

三、MainActivity代码

 CustomDialog.Builder builder = new CustomDialog.Builder(MainActivity.this);
                builder.setMessage("这个就是自定义的提示框");
                builder.setTitle("提示");
                builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.dismiss();
                        //设置你的操作事项
                        Toast.makeText(MainActivity.this,"queding",Toast.LENGTH_SHORT).show();
                    }
                });

                builder.setNegativeButton("取消",
                        new android.content.DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int which) {
                                Toast.makeText(MainActivity.this,"queding",Toast.LENGTH_SHORT).show();
                                dialog.dismiss();
                            }
                        });

                builder.create().show();

四、自定义DialogClass

package com.cavytech.widget;

import android.app.Dialog;
import android.content.Context;
import android.content.DialogInterface;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.LinearLayout;

            return this;
        }

            return this;
        }

        public Builder setTitle(String title) {

            return this;
        }

        public Builder setContentView(View v) {
            this.contentView = v;
            return this;
        }

        /**

         */

            this.positiveButtonClickListener = listener;
            return this;
        }

        public Builder setPositiveButton(String positiveButtonText,
                                         DialogInterface.OnClickListener listener) {

                    .getText(negativeButtonText);

            return this;
        }
