**RecyclerView.HORIZONTAL** (水平滑动)
**RecyclerView.VERTICAL** (垂直滑动)| 16 | |setScrollMode(int mode)|设置滚动模式:
**SCROLL_MODE_NORMAL** (普通模式)
**SCROLL_MODE_OVERFLOW** (允许溢出)
**SCROLL_MODE_LOOP** (无限循环)
| 17 | |setItemDirectionFixed(boolean isFixed)|设置Item是否保持垂直| 18 | |setAutoSelect(boolean isAutoSelect)|设置是否开启自动选中效果| 19 | |setAutoSelectFraction(float position)|设置自动选中的目标落点 (0~1)| 20 | |setFlingEnable(boolean enable)|设置惯性滚动是否开启| 21 | |setCacheCount(int count)|设置Item缓存个数| 22 | |setItemScaleRatio(float... ratios)|设置平滑缩放比例
**ratios**: 缩放比例， 数组长度必须是双数，
**偶数索引**表示要**缩放的比例**
**奇数索引**表示在**路径上的位置** (0~1)
奇数索引必须要递增，即越往后的数值应越大
例如：
**setItemScaleRatio(0.8, 0.5)**
表示在路径的50%处把Item缩放到原来的80%
**setItemScaleRatio(0, 0, 1, 0.5, 0, 1)**
表示在起点处的Item比例是原来的0%，在路径的50%处会恢复原样
到路径终点处会缩小到0%| 23 | |scrollToPosition(int position)|将目标Item滚动到自动选中的落点(setAutoSelectFraction)
例如 setAutoSelectFraction(0) 则滚动到Path的起点处
若为1，则滚动到路径终点处，0.6则路径的60%处 (默认: 0.5)| 24 | |smoothScrollToPosition(int position)|同上，此方法为平滑滚动，即选中时会播放动画
动画时长通过 setFixingAnimationDuration 方法来设置| 25 | |setFixingAnimationDuration(long duration)|设置自动选中后的选中动画时长| 26 | |setOnItemSelectedListener(Listener listener)|设置Item被选中后的监听器 (需开启自动选中才生效)| 27 | 28 | 29 | ### 使用示例： 30 | ```java 31 | mPathLayoutManager = new PathLayoutManager(path, itemOffset); 32 | mRecyclerView.setLayoutManager(mPathLayoutManager); 33 | ``` 34 | 35 | ### Demo下载: [app-debug.apk](https://github.com/wuyr/PathLayoutManager/raw/master/app-debug.apk) 36 | ### 库源码地址： https://github.com/Ifxcyr/PathLayoutManager 37 | 38 | ### 效果： 39 | ![preview](https://github.com/wuyr/PathLayoutManager/raw/master/previews/preview.gif) ![preview](https://github.com/wuyr/PathLayoutManager/raw/master/previews/preview2.gif) 40 | ![preview](https://github.com/wuyr/PathLayoutManager/raw/master/previews/preview3.gif) ![preview](https://github.com/wuyr/PathLayoutManager/raw/master/previews/preview4.gif) 41 | ![preview](https://github.com/wuyr/PathLayoutManager/raw/master/previews/preview7.gif) ![preview](https://github.com/wuyr/PathLayoutManager/raw/master/previews/preview8.gif) 42 | ![preview](https://github.com/wuyr/PathLayoutManager/raw/master/previews/preview5.gif) ![preview](https://github.com/wuyr/PathLayoutManager/raw/master/previews/preview6.gif) 43 | -------------------------------------------------------------------------------- /app-debug.apk: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/wuyr/PathLayoutManager/2e234b28b35bf323a14893e70245b8c20443286d/app-debug.apk -------------------------------------------------------------------------------- /app/.gitignore: -------------------------------------------------------------------------------- 1 | /build 2 | -------------------------------------------------------------------------------- /app/build.gradle: -------------------------------------------------------------------------------- 1 | apply plugin: 'com.android.application' 2 | 3 | android { 4 | compileSdkVersion 27 5 | defaultConfig { 6 | applicationId "com.wuyr.pathlayoutmanagertest" 7 | minSdkVersion 21 8 | targetSdkVersion 27 9 | versionCode 4 10 | versionName "1.3" 11 | testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 12 | } 13 | buildTypes { 14 | release { 15 | minifyEnabled false 16 | proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 17 | } 18 | } 19 | compileOptions { 20 | targetCompatibility 1.8 21 | sourceCompatibility 1.8 22 | } 23 | } 24 | 25 | dependencies { 26 | implementation fileTree(dir: 'libs', include: ['*.jar']) 27 | implementation 'com.android.support:appcompat-v7:27.1.1' 28 | implementation 'com.android.support:recyclerview-v7:27.1.1' 29 | implementation 'com.android.support:cardview-v7:27.1.1' 30 | implementation 'com.android.support.constraint:constraint-layout:1.1.3' 31 | testImplementation 'junit:junit:4.12' 32 | androidTestImplementation 'com.android.support.test:runner:1.0.2' 33 | androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2' 34 | 35 | implementation 'com.wuyr:pathlayoutmanager:1.0.3' 36 | } 37 | -------------------------------------------------------------------------------- /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 *;
