Android Custom Open Source Library EasyView implementation details

Configure EasyView

This is a simple and convenient Android custom View library. I have always had an idea to create an open source library. Now this idea has been implemented. If you have any custom Views you need to put forward, you may not necessarily adopt them. If you are reasonable, you will not be able to adopt them. If the time period is not guaranteed, we must do what we can and be more down-to-earth.

1. Project or Configuration

The code has been pushed toMavenCentral(),existAndroid Studio 4.2In future versions, use it when creating a project by default.MavenCentral(), notjcenter()。

If it is the previous version, it needs to berepositories{}Added in closuremavenCentral()The difference is that the old version of Android Studio is in the projectAdded in, and the new version is engineeringAdded inIf you have already added, do not add it repeatedly.

repositories {
    ...
    mavenCentral()
}

2. Use module configuration

For example, inappUsed in the module, open the app module,existdependencies{}Just add it under the closure, remember toSync Now。

dependencies {
    implementation ':easyview:1.0.2'
}
