"tab" + i : mPagerAdapter.getPageTitle(i).toString(); 30 | if(creator!=null){ 31 | addTab(creator.create(i), false); 32 | }else { 33 | addTab(newTab().setText(title),false); 34 | } 35 | } 36 | if (mViewPager != null && adapterCount > 0) { 37 | final int curItem = mViewPager.getCurrentItem(); 38 | if (curItem != getSelectedTabPosition() && curItem < getTabCount()) { 39 | selectTab(getTabAt(curItem)); 40 | } 41 | } 42 | } 43 | } 44 | ``` 45 | 46 | * 更改了官方的TabLayou的自定义view的使用策略（官方的自定义tabiten的样式是受限制的，要有固定id的`ImageView`和固定id的`TextView`），添加了新的接口 47 | 48 | ```java 49 | public interface OnCustomTabViewRenderListener { 50 | /** 51 | * 当需要tab的item需要自定义view的时候，通过这个接口方法通知视图渲染 52 | * 53 | * @param tab 54 | */ 55 | void onRender(VerticalTab tab); 56 | } 57 | ``` 58 | 59 | * `Tab`更换为`VerticalTab` 60 | 61 | * 修改实现的`TabView` 62 | 63 | 除此之外，逻辑基本保持与官方的TabLayout一致 64 | 65 | ### VerticalViewPager 66 | 67 | 垂直切换的`ViewPager`提供了两种常规方案： 68 | 69 | * 基于`ViewPager.PageTransformer`实现。会存在嵌套recyclerview的滑动冲突问题 70 | 71 | * 修改`ViewPager`的源码，做对应的修改。可以看这个项目[InfiniteCycleViewPager](https://github.com/Devlight/InfiniteCycleViewPager) 72 | 73 | ​ 74 | 75 | ## 方案使用 76 | 77 | 不管是`VerticalTabLayout`还是`VerticalViewPager`，两者的使用方法都与官方的使用API和方法一致。对于`VerticalTabLayout`存在的差异有 78 | 79 | * 不支持在xml文件中嵌套使用`TabItem`添加tab 80 | * `setupWithViewPager()`可以携带一个接口对象，用于自定义tab的视图 81 | * xml中支持定义的属性不同，详情可以参考`attrs.xml`当中的定义 82 | 83 | 具体可以参考demo 84 | 85 | ## 实现效果 86 | 87 | ![](/sample.gif) -------------------------------------------------------------------------------- /app/.gitignore: -------------------------------------------------------------------------------- 1 | /build 2 | -------------------------------------------------------------------------------- /app/build.gradle: -------------------------------------------------------------------------------- 1 | apply plugin: 'com.android.application' 2 | 3 | apply plugin: 'kotlin-android' 4 | 5 | apply plugin: 'kotlin-android-extensions' 6 | 7 | android { 8 | compileSdkVersion 26 9 | defaultConfig { 10 | applicationId "tech.easily.verticaltablayout" 11 | minSdkVersion 15 12 | targetSdkVersion 26 13 | versionCode 1 14 | versionName "1.0" 15 | testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 16 | } 17 | buildTypes { 18 | release { 19 | minifyEnabled false 20 | proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 21 | } 22 | } 23 | } 24 | 25 | dependencies { 26 | implementation fileTree(dir: 'libs', include: ['*.jar']) 27 | implementation"org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version" 28 | implementation 'com.android.support:appcompat-v7:26.1.0' 29 | implementation 'com.android.support.constraint:constraint-layout:1.0.2' 30 | testImplementation 'junit:junit:4.12' 31 | androidTestImplementation 'com.android.support.test:runner:1.0.1' 32 | androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1' 33 | implementation project(":lib") 34 | implementation 'com.android.support:recyclerview-v7:26.1.0' 35 | } 36 | -------------------------------------------------------------------------------- /app/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 *;
