Add the JitPack repository in your root build.gradle at the end of repositories: 13 | ```groovy 14 | allprojects { 15 | repositories { 16 | ... 17 | maven { url 'https://jitpack.io' } 18 | } 19 | } 20 | ``` 21 | Step 2. Add the dependency in your app build.gradle: 22 | ```groovy 23 | dependencies { 24 | // 其中latest-version类似 v1.0.3 25 | implementation 'com.github.yuruiyin:AppbarLayoutBehavior:latest-version' 26 | } 27 | ``` 28 | ### xml 29 | ```xml 30 | 38 | 39 | ...... 40 | 41 | 42 | ``` 43 | 44 | ### 混淆 45 | 若使用support库，则需要保证support库中的代码不被混淆，请在proguard-rules.pro中添加如下配置： 46 | ```proguard 47 | # 保留support下的所有类及内部类 48 | -keep class android.support.**{*;} 49 | -dontwarn android.support.v4.** 50 | # 保留继承support库的类 51 | -keep public class * extends android.support.v4.** 52 | -keep public class * extends android.support.v7.** 53 | -keep public class * extends android.support.annotation.** 54 | ``` 55 | 56 | 若已迁移到androidx，则需要添加如下配置: 57 | ```proguard 58 | -keep class com.google.android.material.** {*;} 59 | -keep class androidx.** {*;} 60 | -keep public class * extends androidx.** 61 | -keep interface androidx.** {*;} 62 | -dontwarn com.google.android.material.** 63 | -dontnote com.google.android.material.** 64 | -dontwarn androidx.** 65 | ``` 66 | 67 | ## 参考 68 | https://blog.csdn.net/vite_s/article/details/78901767 69 | -------------------------------------------------------------------------------- /appbarlayoutbehavior/.gitignore: -------------------------------------------------------------------------------- 1 | /build 2 | -------------------------------------------------------------------------------- /appbarlayoutbehavior/build.gradle: -------------------------------------------------------------------------------- 1 | apply plugin: 'com.android.library' 2 | apply plugin: 'com.github.dcendents.android-maven' 3 | 4 | group='com.github.yuruiyin' 5 | 6 | android { 7 | compileSdkVersion rootProject.ext.compileSdkVersion 8 | 9 | defaultConfig { 10 | minSdkVersion rootProject.ext.minSdkVersion 11 | buildToolsVersion rootProject.ext.buildToolsVersion 12 | targetSdkVersion rootProject.ext.targetSdkVersion 13 | versionCode 1 14 | versionName "1.0" 15 | 16 | testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" 17 | 18 | } 19 | 20 | buildTypes { 21 | release { 22 | minifyEnabled false 23 | proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 24 | } 25 | } 26 | 27 | } 28 | 29 | dependencies { 30 | implementation fileTree(dir: 'libs', include: ['*.jar']) 31 | 32 | implementation 'androidx.appcompat:appcompat:1.0.2' 33 | implementation 'com.google.android.material:material:1.0.0' 34 | testImplementation 'junit:junit:4.12' 35 | androidTestImplementation 'androidx.test:runner:1.2.0' 36 | androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0' 37 | } 38 | -------------------------------------------------------------------------------- /appbarlayoutbehavior/proguard-rules.pro: -------------------------------------------------------------------------------- 1 | # Add project specific ProGuard rules here. 2 | # You can control the set of applied configuration files using the 3 | # proguardFiles setting in build.gradle. 4 | # 5 | # For more details, see 6 | # http://developer.android.com/guide/developing/tools/proguard.html 7 | 8 | # If your project uses WebView with JS, uncomment the following 9 | # and specify the fully qualified class name to the JavaScript interface 10 | # class: 11 | #-keepclassmembers class fqcn.of.javascript.interface.for.webview { 12 | # public *;
