Android开发必知 九种对话框的实现方法

在开发过程中，与用户交互式免不了会用到对话框以实现更好的用户体验，所以掌握几种对话框的实现方法还是非常有必要的。在看具体实例之前先对AlertDialog做一个简单介绍。AlertDialog是功能最丰富、实践应用最广的对话框，它可以生成各种内容的对话框。但实际上AlertDialog生成的对话框总体可分为以下4个区域：图标区、标题区、内容区、按钮区。

这里总结了九种对话框的实现方法，有需要的朋友可以来学习下了

除了popupwindow实现稍微麻烦一点，其他形似都相对简单，熟悉2便即可

布局，就是一堆的button

<?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" >
  <TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="各种Dialog合集" />
  <Button
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="普通Dialog"
    android:id="@+id/btn_diaNormal"/>
  <Button
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="多按钮Dialog"
    android:id="@+id/btn_diaMulti"/>
  <Button
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="列表Dialog"
    android:id="@+id/btn_diaList"/>
  <Button
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="单项选择Dialog"
    android:id="@+id/btn_diaSigChos"/>
  <Button
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="多项选择Dialog"
    android:id="@+id/btn_diaMultiChos"/>
  <Button
    android:layout_width="fill_parent"

    android:text="进度条Dialog"
    android:id="@+id/btn_diaReadProcess"/>
  <Button
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="读取中Dialog"
    android:id="@+id/btn_diaProcess"/>
  <Button
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="自定义Dialog"
    android:id="@+id/btn_diaCustom"/>
  <Button

    android:layout_height="wrap_content"
    android:text="PopUpWindow实现的dialog"
