解决Gradle依赖关系,不同一个库不同版本的兼容问题
问题分析
系统提示错误
我们在app的build.gradle文件看见一个报错。
原因是我们设置了v7的版本com.android.support:appcompat-v7:26.1.0,但是我们在引用第三方库的时候出现了报错。大致的意思就是我们使用的v7的库和我们的recyclerview的搭配版本不相同，这会使我们的版本不兼容。
分析gradle依赖
为了进一步验证,我们使用了gradle app:dependencies | log.txt 命令，对项目的编译时间和运行时间的依赖库进行查看。

上面的标识代表着不同的含义，我来解释下：
*号表示,gradle使用了相同版本或者另一个版本来作为依赖。->号,表示gradle将使用符号后面的版本作为依赖。
报错原因

可以看见，我们的bga-refreshlayout使用的recyclerview还是24.0.0,这就导致了我们的recyclerview的版本和当前的v7版本不兼容。
修复错误
思路
除bga-refreshlayout外,其余类库均统一版本库recyclerview的版本库。
- 统一gradle的
recyclerview版本。
implementation rootProject.ext.dependencies["recyclerview-v7"]
这里加入这段代码，项目中所有的引用库都会统一引用recyclerview。
- 配置
bga-refreshlayout使用自己的版本库。
implementation(rootProject.ext.dependencies["refreshlayout"]) {
exclude group: 'com.android.support'
}
命令检查

看上面的依赖，问题得以解决。
