This is a simple form validation in Android. This library will help for required form. Thank you for developer : alimodares2003

The simplest way to add reactive validation to your app.


in your application, there are fields that must be validated. When the number of validation rules becomes greater than 1, to control the display of errors in the fields becomes difficult.


Separate your validation logic by S in SOLID, into own classes. After that, attach validation rules to your fields and combine validation results for change some ui states (ex. change visibility of button)

Convalida is a simple, lightweight and powerful field validation library for Android.

Validation library for use individual validation and with views.

Simple and light library to do validate observable fields with MVVM for android

Each ValidatedObservableField work like ObservableField, but it have 3 observables properties:

  • valid - boolean true if ALL Rules are valid
  • errorMessage - contains NULL or errorMessage from first invalid Rule

Rules are validated one by one (the order is important), the first invalid Rule will break the chain and set errorMessage. Rules are validated onPropertyChange. You can create your own rules using Rule interface. You can use single Rule or many by RuleCommand.
