      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,

      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

# RecyclerViewBanner
使用RecyclerView做的轮播图

### 前言
之前做的轮播图，对于十几个图片什么的能够满足，但是万一有几千张，几万张就容易造成内存泄露，使用RecyclerView做的轮播，可以利用它自身的复用机制，比较节省内存。所以这种方式感觉效果更好。

### 1.2.1版本更新内容
    1. 指示器Indicator相关属性前缀同一为“indicator”。
    2. 增加几个Indicator的相关属性：
        rvb_indicatorSize：单个Indicator元素的方形区域尺寸；
        rvb_indicatorSpace：两个Indicator元素的间距；
        rvb_indicatorMargin：Indicator距离外边框的间距；
        rvb_indicatorGravity：Indicator在广告栏内底部的相对位置。
	    rvb_autoPlaying：是否自动滚动，true自动滚动，false停止自动滚动

    3. 将BannerView和IndicatorView的ImageView替换为AppCompatImageView，这样在Fragment中也可使用Compat属性，如使用svg矢量图等。
    4. 可通过xml自由配置选中和未选中状态的资源，支持color, shape, png, svg，相当灵活。
    5. lib的build.gradle中改compile为provided，这样当app的build.gradle中的版本低于lib也不会报错。
   **注意：SnapHelper是support-compat:24.2.0才引入的，compile的编译版本必须高于24.2.0才可以**(是编译版本高于24.2.0，兼容其以下版本的，都可以使用，大家别理解错。)

![](https://github.com/loonggg/RecyclerViewBanner/blob/master/image/sss.gif?raw=true)

## 使用方法
### Step 1. Add the JitPack repository to your build file
Add it in your root build.gradle at the end of repositories:
```java
  allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
  }
```

### Step 2. Add the dependency
```java
   dependencies {
        implementation 'com.github.loonggg:RecyclerViewBanner:v1.2.3'
   }
 ```

### Step 3. There are a few xml attributes to customise the  RecyclerViewBanner

 * rvb_indicatorSelectedSrc 设置底部导航指示器或者点选中的样式
 * rvb_indicatorUnselectedSrc 设置底部导航指示器或者点未选中状态的样式
 * rvb_interval 设置轮播图滚动间隔时间
 * rvb_showIndicator 设置是否显示底部指示导航小圆点
 * rvb_indicatorSize 设置指示器的大小
 * rvb_indicatorSpace 设置轮播指示器的间隔
 * rvb_indicatorMargin 设置轮播指示器Indicator距离外边框的间距
 * rvb_indicatorGravity 设置底部轮播导航指示器的位置 [left，center，right]
 * rvb_autoPlaying：是否自动滚动，true自动滚动，false禁止自动滚动
