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

直接上源码

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:layout_height="wrap_content"     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_width="fill_parent"     android:layout_height="wrap_content"     android:text="PopUpWindow实现的dialog"     android:id="@+id/btn_popUpDia"/> </LinearLayout> 

以上是Android开发必知 九种对话框的实现方法,代码主要用AlertDialog生成的对话框,它的功能丰富、使用最广。
