Android中AlertDialog各种对话框的用法实例详解

 目标效果：

程序运行，显示图一的几个按钮，点击按钮分别显示图二到图六的对话框，点击对话框的某一项或者按钮，也会显示相应的吐司输出。

1.activity_main.xml页面存放五个按钮。

activity_main.xml页面：

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
tools:context=".mainactivity" > 
<button 
android:id="@+id/btnsure" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:layout_margintop="10dp" 
android:text="确认对话框"/> 
<button 
android:id="@+id/btnradio" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:layout_margintop="60dp" 
android:text="单选对话框"/> 
<button 
android:id="@+id/btncheck" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:layout_margintop="110dp" 
android:text="多选对话框"/> 
<button 
android:id="@+id/btnlist" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:layout_margintop="160dp" 
android:text="列表对话框"/> 
<button 
android:id="@+id/btnmy" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:layout_margintop="210dp" 
android:text="自定义对话框"/> 
</relativelayout> 

2.新建dialog.xml页面，作为最后一个自定义对话框的布局页面。

dialog.xml页面：

<?xml version="1.0" encoding="utf-8"?> 
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:orientation="vertical" > 
<linearlayout 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:orientation="horizontal" > 
<edittext 
android:id="@+id/edinput" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:layout_weight="2" > 
<requestfocus /> 
</edittext> 
<button 
android:id="@+id/btnok" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:layout_weight="1" 
android:text="确定" /> 
</linearlayout> 
<imageview 
android:id="@+id/ivpicture" 
android:layout_width="wrap_content" 
android:layout_height="280dp" 
android:src="@drawable/white" /> 
<textview 
android:id="@+id/textview1" 
android:layout_gravity="center" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:text="textview" /> 
</linearlayout> 

3.mainactivity.java页面处理对话框的弹出及点击事件。

mainactivity.java页面：

package com.example.alertdialog; 
import android.os.bundle; 
import android.app.activity; 
import android.app.alertdialog; 
import android.content.dialoginterface; 
import android.view.layoutinflater; 
import android.view.menu; 
import android.view.view; 
import android.view.view.onclicklistener; 
import android.widget.button; 
import android.widget.toast; 
public class mainactivity extends activity implements onclicklistener { 
private button btnsure,btnradio,btncheck,btnlist,btnmy; 
private string[] sexlist={"男","女"};//单选列表 
private string[] likelist={"篮球","足球","打游戏","听音乐","看电影"};//多选列表 
private string[] itemlist={"项目经理","策划","测试","美工","程序员"};//列表 
@override 
protected void oncreate(bundle savedinstancestate) { 
super.oncreate(savedinstancestate); 
setcontentview(r.layout.activity_main); 
getid();//获取控件id 
click();//按钮绑定点击事件 
} 
/*获取控件id*/ 
private void getid() { 
btnsure = (button) findviewbyid(r.id.btnsure); 
btnradio=(button) findviewbyid(r.id.btnradio); 
btncheck=(button) findviewbyid(r.id.btncheck); 
btnlist=(button) findviewbyid(r.id.btnlist); 
btnmy=(button) findviewbyid(r.id.btnmy); 
} 
/*按钮绑定点击事件*/ 
private void click() { 
btnsure.setonclicklistener(this); 
btnradio.setonclicklistener(this); 
btncheck.setonclicklistener(this); 
btnlist.setonclicklistener(this); 
btnmy.setonclicklistener(this); 
} 
@override 
public boolean oncreateoptionsmenu(menu menu) { 
getmenuinflater().inflate(r.menu.main, menu); 
return true; 
} 
@override 
public void onclick(view view) { 
switch (view.getid()) { 
case r.id.btnsure: 
showdialog1();//确认对话框 
break; 
case r.id.btnradio: 
showdialog2();//单选对话框 
break; 
case r.id.btncheck: 
showdialog3();//多选对话框 
break; 
case r.id.btnlist: 
showdialog4(); 
break; 
case r.id.btnmy: 
showdialog5(); 
break; 
} 
} 
/*确认对话框*/ 
private void showdialog1() { 
alertdialog.builder builder=new alertdialog.builder(this); 
builder.settitle("确认对话框");//设置标题 
builder.seticon(r.drawable.ic_launcher);//设置图标 
builder.setmessage("确认对话框提示内容");//设置内容 
/*添加对话框中确定按钮和点击事件*/ 
builder.setpositivebutton("确定",new dialoginterface.onclicklistener() { 
@override 
public void onclick(dialoginterface arg0, int arg1) { 
toast.maketext(mainactivity.this,"点击了确定按钮",toast.length_short).show(); 
} 
}); 
/*添加对话框中取消按钮和点击事件*/ 
builder.setnegativebutton("取消",new dialoginterface.onclicklistener() { 
@override 
public void onclick(dialoginterface arg0, int arg1) { 
toast.maketext(mainactivity.this,"点击了取消按钮",toast.length_short).show(); 
} 
}); 
alertdialog dialog=builder.create();//获取dialog 
dialog.show();//显示对话框 
} 
/*单选对话框*/ 
private void showdialog2() { 
alertdialog.builder builder=new alertdialog.builder(this); 
builder.settitle("性别");//设置标题 
builder.seticon(r.drawable.ic_launcher);//设置图标 
/*参数一位单选列表文字，参数二为默认第几个选中（-1默认不选中），参数三是创建监听器*/ 
builder.setsinglechoiceitems(sexlist,-1,new dialoginterface.onclicklistener() { 
@override 
public void onclick(dialoginterface dialog, int which) { 
string sex=sexlist[which]; 
toast.maketext(mainactivity.this,"这个人性别为"+sex, toast.length_short).show(); 
} 
}); 
/*添加对话框中取消按钮点击事件*/ 
builder.setnegativebutton("取消",new dialoginterface.onclicklistener() { 
@override 
public void onclick(dialoginterface dialog, int which) { 
dialog.dismiss();//关闭对话框 
} 
}); 
alertdialog dialog=builder.create();//获取dialog 
dialog.show();//显示对话框 
} 
/*多选对话框*/ 
private void showdialog3() { 
alertdialog.builder builder=new alertdialog.builder(this); 
builder.settitle("爱好");//设置标题 
builder.seticon(r.drawable.ic_launcher);//设置图标 
/*参数同单选对话框一样，另外第二个参数默认不选中为null，而不是-1*/ 
builder.setmultichoiceitems(likelist,null,new dialoginterface.onmultichoiceclicklistener() { 
@override 
public void onclick(dialoginterface dialog, int which, boolean ischecked) { 
if(ischecked){ 
toast.maketext(mainactivity.this,"我喜欢"+likelist[which],toast.length_short).show(); 
}else{ 
toast.maketext(mainactivity.this,"我不喜欢"+likelist[which],toast.length_short).show(); 
} 
} 
}); 
/*添加对话框中取消按钮点击事件*/ 
builder.setnegativebutton("取消",new dialoginterface.onclicklistener() { 
@override 
public void onclick(dialoginterface dialog, int which) { 
dialog.dismiss();//关闭对话框 
} 
}); 
alertdialog dialog=builder.create();//获取dialog 
dialog.show();//显示对话框 
} 
/*列表对话框*/ 
private void showdialog4() { 
alertdialog.builder builder=new alertdialog.builder(this); 
builder.settitle("部门列表");//设置标题 
builder.seticon(r.drawable.ic_launcher);//设置图标 
builder.setitems(itemlist,new dialoginterface.onclicklistener() { 
@override 
public void onclick(dialoginterface dialog, int which) { 
toast.maketext(mainactivity.this,"我点击了"+itemlist[which],toast.length_short).show(); 
} 
}); 
alertdialog dialog=builder.create();//获取dialog 
dialog.show();//显示对话框 
} 
/*自定义对话框*/ 
private void showdialog5() { 
layoutinflater inflater=layoutinflater.from(this); 
view view=inflater.inflate(r.layout.dialog,null);//获取自定义布局 
alertdialog.builder builder=new alertdialog.builder(this); 
builder.settitle("自定义对话框");//设置标题 
builder.seticon(r.drawable.ic_launcher);//设置图标 
builder.setview(view);//设置自定义样式布局到对话框 
alertdialog dialog=builder.create();//获取dialog 
dialog.show();//显示对话框 
} 
}

4.运行就出现目标效果了。
