本文详细介绍了如何在Android应用中创建一个包含跳转和取消按钮的自定义对话框，通过调用`Dialog2()`虚函数来实现用户交互，并通过设置按钮的监听器来触发相应的操作，包括打开指定网页或取消操作。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

效果：
会弹出一个提示框，有跳转和取消两个钮。
点击取消以后，无任何操作。
点击前往以后，会调用浏览器打开指定网址。

在启动页oncreate中添加：
invoke-virtual {p0, v0}, L当前页面地址;->setContentView(I)V
#v0是当前页面在public中的数值，p0无所谓，L路径要与当前java路径保持一致

.line 16
invoke-virtual {p0}, L当前页面地址;->Dialog2()V
#p0不管，L路径要与当前java路径保持一致

在当前页面下添加虚函数（# virtual methods）：
.method public Dialog2()V
.locals 3

.prologue
.line 22
new-instance v0, Landroid/app/AlertDialog$Builder;

#v0=(UninitRef,Landroid/app/AlertDialog$Builder;);
invoke-direct {v0, p0}, Landroid/app/AlertDialog$Builder;-><init>(Landroid/content/Context;)V

.line 23
.local v0, "builder":Landroid/app/AlertDialog$Builder;
#v0=(Reference,Landroid/app/AlertDialog$Builder;);
const/4 v1, 0x0

#v1=(Null);
invoke-virtual {v0, v1}, Landroid/app/AlertDialog$Builder;->setIcon(Landroid/graphics/drawable/Drawable;)Landroid/app/AlertDialog$Builder;

.line 24
const-string v1, "\u6e29\u99a8\u63d0\u793a"

#v1=(Reference,Ljava/lang/String;);
invoke-virtual {v0, v1}, Landroid/app/AlertDialog$Builder;->setTitle(Ljava/lang/CharSequence;)Landroid/app/AlertDialog$Builder;

.line 25
const-string v1, "\u65e0\u63d0\u793a"

invoke-virtual {v0, v1}, Landroid/app/AlertDialog$Builder;->setMessage(Ljava/lang/CharSequence;)Landroid/app/AlertDialog$Builder;

.line 26
const-string v1, "\u524d\u5f80"

new-instance v2, L当前页面地址$跳转;

#v2=(UninitRef,L当前页面地址$跳转;);
invoke-direct {v2, p0}, L当前页面地址$跳转;-><init>(L当前页面地址;)V

#v2=(Reference,L当前页面地址$跳转;);
invoke-virtual {v0, v1, v2}, Landroid/app/AlertDialog$Builder;->setPositiveButton(Ljava/lang/CharSequence;Landroid/content/DialogInterface$OnClickListener;)Landroid/app/AlertDialog$Builder;

.line 39
const-string v1, "\u53d6\u6d88"

new-instance v2, L当前页面地址$取消;

#v2=(UninitRef,L当前页面地址$取消;);
invoke-direct {v2, p0}, L当前页面地址$取消;-><init>(L当前页面地址;)V

#v2=(Reference,L当前页面地址$取消;);
invoke-virtual {v0, v1, v2}, Landroid/app/AlertDialog$Builder;->setNegativeButton(Ljava/lang/CharSequence;Landroid/content/DialogInterface$OnClickListener;)Landroid/app/AlertDialog$Builder;

.line 47
invoke-virtual {v0}, Landroid/app/AlertDialog$Builder;->create()Landroid/app/AlertDialog;

move-result-object v1

invoke-virtual {v1}, Landroid/app/AlertDialog;->show()V

.line 48
return-void
.end method

在启动页目录插入两个新文件：
MainActivity$1.smali
MainActivity$2.smali
#如果出现重名，则递进

MainActivity$1.smali文件内容：
