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>

这里写图片描述

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;import android.widget.TextView;import com.cavytech.wear2.R;/** * Created by LiBin on 2016/6/16. */public class CustomDialog extends Dialog {    public CustomDialog(Context context) {        super(context);    }    public CustomDialog(Context context, int theme) {        super(context, theme);    }    public static class Builder {        private Context context;        private String title;        private String message;        private String positiveButtonText;        private String negativeButtonText;        private View contentView;        private DialogInterface.OnClickListener positiveButtonClickListener;        private DialogInterface.OnClickListener negativeButtonClickListener;        public Builder(Context context) {            this.context = context;        }        public Builder setMessage(String message) {            this.message = message;            return this;        }        /**         * Set the Dialog message from resource         *         * @param         * @return         */        public Builder setMessage(int message) {            this.message = (String) context.getText(message);            return this;        }        /**         * Set the Dialog title from resource         *         * @param title         * @return         */        public Builder setTitle(int title) {            this.title = (String) context.getText(title);            return this;        }        /**         * Set the Dialog title from String         *         * @param title         * @return         */        public Builder setTitle(String title) {            this.title = title;            return this;        }        public Builder setContentView(View v) {            this.contentView = v;            return this;        }        /**         * Set the positive button resource and it's listener         *         * @param positiveButtonText         * @return         */        public Builder setPositiveButton(int positiveButtonText,                                         DialogInterface.OnClickListener listener) {            this.positiveButtonText = (String) context                    .getText(positiveButtonText);            this.positiveButtonClickListener = listener;            return this;        }        public Builder setPositiveButton(String positiveButtonText,                                         DialogInterface.OnClickListener listener) {            this.positiveButtonText = positiveButtonText;            this.positiveButtonClickListener = listener;            return this;        }        public Builder setNegativeButton(int negativeButtonText,                                         DialogInterface.OnClickListener listener) {            this.negativeButtonText = (String) context                    .getText(negativeButtonText);            this.negativeButtonClickListener = listener;            return this;        }        public Builder setNegativeButton(String negativeButtonText,                                         DialogInterface.OnClickListener listener) {            this.negativeButtonText = negativeButtonText;            this.negativeButtonClickListener = listener;            return this;        }        public CustomDialog create() {            LayoutInflater inflater = (LayoutInflater) context                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);            // instantiate the dialog with the custom Theme            final CustomDialog dialog = new CustomDialog(context, R.style.Dialog);            View layout = inflater.inflate(R.layout.dialog_normal_layout, null);            dialog.addContentView(layout, new LinearLayout.LayoutParams(                    LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));            // set the dialog title            ((TextView) layout.findViewById(R.id.title)).setText(title);            // set the confirm button            if (positiveButtonText != null) {                ((TextView) layout.findViewById(R.id.positiveTextView))                        .setText(positiveButtonText);                if (positiveButtonClickListener != null) {                    ((TextView) layout.findViewById(R.id.positiveTextView))                            .setOnClickListener(new View.OnClickListener() {                                public void onClick(View v) {                                    positiveButtonClickListener.onClick(dialog,                                            DialogInterface.BUTTON_POSITIVE);                                }                            });                }            } else {                // if no confirm button just set the visibility to GONE                layout.findViewById(R.id.positiveTextView).setVisibility(                        View.GONE);            }            // set the cancel button            if (negativeButtonText != null) {                ((TextView) layout.findViewById(R.id.negativeTextView))                        .setText(negativeButtonText);                if (negativeButtonClickListener != null) {                    ((TextView) layout.findViewById(R.id.negativeTextView))                            .setOnClickListener(new View.OnClickListener() {                                public void onClick(View v) {                                    negativeButtonClickListener.onClick(dialog,                                            DialogInterface.BUTTON_NEGATIVE);                                }                            });                }            } else {                // if no confirm button just set the visibility to GONE                layout.findViewById(R.id.negativeTextView).setVisibility(                        View.GONE);

           }            dialog.setContentView(layout);            return dialog;        }    }}
