我正在尝试从https://android-arsenal.com/details/1/1375添加样式化的进度条

它说:

将特定存储库添加到构建文件中:

repositories {
   maven {
      url "https://jitpack.io"
   }
}

在构建文件中添加依赖项(不要忘记指定正确的限定符,通常是'aar'):

dependencies {
   compile 'com.github.akexorcist:Android-RoundCornerProgressBar:1.0.0'
}

好吧,我做到了... build.gradle(Project)

buildscript {
repositories {
    jcenter()
    maven {
      url "https://jitpack.io"
   }

}
  dependencies {
    classpath 'com.android.tools.build:gradle:1.1.0'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
  }
}

allprojects {
  repositories {
    jcenter()
  }
}

build.gradle(Module):apply plugin:'com.android.application'

android {compileSdkVersion 21 buildToolsVersion"21.1.2"

defaultConfig {
    applicationId "com.example.chaz.simsirl"
    minSdkVersion 15
    targetSdkVersion 21
    versionCode 1
    versionName …

因此，我正在尝试创建一个网站，您可以在其中输入名为 Info 的对象的标题和价格。当我输入标题和价格并按提交时，它被重定向到的页面显示“找不到 InfosController 的操作\'更新\'”。我希望它闪烁一条消息，通知用户对象已成功创建。有什么帮助吗？

控制器/infos_controller.rb

class InfosController < ApplicationController\n    def index\n    @info = Info.new\n  end\n\ndef create\n    @info = Info.new(params[:info])\n\nif @info.save\n    flash[:notice] = \'Object created successfully, thank you\'\n    render :index\n   else\n    flash[:notice] = \'Sorry! Object was not created successfully\'\n    render :new\n  end\nend\n  def update\n    @info = Info.find(params[:id])\n    if @info.update_attributes(params[:info])\n        # if update is successful\n    else \n        # if update is unsuccessful\n    end\n    redirect_to infos_path\nend\nend\n

视图/infos/index.html.erb

<h1>Please enter information about an Info object</h1>\n<%= form_for @info, url: {action: …
