Butterknife does not create anything in .apt_generated directory

由 心不动则不痛 提交于 2019-12-11 08:49:42
问题 I am trying to use Butterknife for injection, but I do not see any classes generated in the .apt_generated directory. I am using eclipse Kepler (service release 2) , enabled annotation processing in my project properties and defined the butterknife-5.0.0.jar as the annotation processor in the factory path. I have 2 views injected into a fragment for testing, and when I clean the project it is built but nothing is generated. Checking the log file and the error_log view I don't see anything

Exposing Member Variables with ButterKnife

问题 Curious question, I'm using ButterKnife and I just discovered you can't use in private methods because ButterKnife creates classes that use them. Doesn't that violates the principle of encapsulation? I mean, then your variables will be exposed to other classes as well, no? 回答1: You are totally right, using Butterknife violates the principle of encapsulation. Butterknife uses its own generated code to perform view look-ups. And those look-ups are done in separate class(-es) hence the fields

Butterknife 8.4.0 does not find views after re-running the app. It gets a NullPointerException

由 二次信任 提交于 2019-12-10 12:30:08
问题 After re-running the app in Android Studio Butterknife.bind(this) does not find the views anymore. The only reliable solution I found so far is by Cleaning/Rebuilding Project and run it again. Then it finds the views again until the next re-run. This is incredibly annoying so far and takes a minimum of two minutes for a rebuild. I have the following build.gradle android { compileSdkVersion 24 buildToolsVersion "25.0.0" defaultConfig { applicationId "xx" minSdkVersion 21 targetSdkVersion 24

关于模块化注意问题

模块化注意问题链接 这篇文章对模块化中的组件化说的很详细了,另外记录一下经常发生的问题: 模块化 某个library module R文件全部爆红无法编译; 因为模块化后, library中的R文件和application不是一样的,library的R文件不是静态常量; 并且还有一个问题就是 有多个R文件,比如kit library中一个基类使用了layout的R文件属于kit的,而xx library继承了这个基类使用的R文件又是另一个R文件,使用ButterKnife之类的框架可能会产生冲突; 解决方案有下面几种： 重新一个Gradle插件，生成一个R2.java文件，这个文件中各个id都是静态常量，这样就可以正常使用了。(ButterKnife就是使用此方式,但是个人使用感觉成本很高;) 使用Android系统提供的最原始的方式，直接用findViewById以及setOnClickListener方式。(这个可以,但是模块化项目就不推荐使用ButterKnife了) 设置项目支持Databinding，然后使用Binding中的对象，但是会增加不少方法数，同时Databinding也会有编译问题和学习成本，但是这些也是小问题，个人觉的问题不大。 来源： CSDN 作者： MrJarvisDong 链接： https://blog.csdn.net/MrJarvisDong

Android: 今日头条屏幕适配的原理？ 1：首先计算出 density，计算公式：当前设备屏幕总宽度（单位为像素）/ 设计图总宽度（单位为 dp) = densitydensity 的意思就是 1 dp 占当前设备多少像素计算density 的原因：在布局文件中填写的是什么单位，最后都会被转化为 px，系统就是通过上面的方法，将你在项目中任何地方填写的单位都转换为 px 但是，今日头条适配方案默认项目中只能以高或宽中的一个作为基准，来进行适配 简述Android中的加固和使用平台? 加固:防止代码反编译,提高代码安全性 加固三方平台,梆梆安全,360加固,爱加密等 区别:梆梆安全,360加固看不到项目中的类,爱加密看的到Java类,单看不到里面的方法实现体,效果比前面差一点点 加固的底层原理:第三方加固的应用会生成一个Apk,然后把你的APK读取出来,在封装到这个第三方应用的APK里面. 如何对APK瘦身? 1)使用混淆, 2)开启shrinkResourse(shrink-收缩),会将没有用到的图片变成一个像素点 3)删除无用的语言资源(删除国际化文件) 4)对于非透明的大图,使用JPG(没有透明度信息),代替PNG格式 5)使用tinypng进行图片压缩 6)使用webp图片格式,进一步压缩图片资源 7)使用第三方包时把用到的代码加到项目中来,避免引用整一个第三方库

问题 I have an Adapter that draws the layouts for my Navigation Drawer. My navigation drawer contains two inner xml files: One being the Header and the other being the Row .
