Input Validator

Input validation and error displaying for any Android view that extends from a TextView. This library is born from frustration towards complex if statements and a desire to make form validation much, much easier.

What does the library do?

Wrap around any View extending from TextView
Allow multiple Validator objects to be attached.
When the View loses focus the input will be validated against the Validators
Display an error message if the input isn't successfully validated
- If the input is wrapped in a TextInputLayout it will be used to display the message
- If the input is not wrapped in a TextInputLayout the error will be shown in the inpput
- The above can be overriden using an OnValidationErrorListener which allows you to do whatever you want with the error received

InputValidator inputValidator = ValidateInputs.validate((TextInputEditText) findViewById(R.id.first_name));
 inputValidator.addValidator(new TextEmptyValidator());

By implementing the Validator object you can create your own validation methods.

public class TextEmptyValidator implements Validator {

@Override
  public boolean validate(String input) {

return !(input == null || input.isEmpty());

  
}

@Override
  public String getValidationMessage() {

return "The text view is empty.";
  
}

}

How to use

Add this to your gradle dependencies.

compile 'uk.co.jordanterry:InputValidator:0.3.0'

Great! If you notice anything that I could be doing better please create an issue and let me know.

I would also LOVE to know if anyone has any Validator ideas, the more the merrier.

okhttp-stats

OkHttp-Stats is an android library built on top of OkHttp3, which is responsible for intercepting all the network calls and for calculating network stats such as the average network speed of the user.

This is more of an analytical tool which can be used to track the success and error response logs.

Can be plugged in to any app which uses okhttp in their networking stack.

Ristretto

Espresso's consistency makes it really easy to learn.

Want to match a view with a specific id? Use withId(R.id.some_id). Need to match with a piece of text? Use withText(R.id.some_text) or withText("some text). Awesome, consistent and it's very clear what it is you are doing.

However...

After a few hours writing test code you'll find your code being a little bit too verbose. Not anymore.

Why should you need to explicitly specify that you are matching with some text if you are passing in some text as a parameter? Some for the view id, you can already see that it is a view id.

Ristretto allows you to write the same test code as you already write, but less verbose.

SpanEZ

Complete abstraction from the Spannable API. Forget about all the boiler plate code and all the Object what nonsense that you have to deal with when working with Spannable.

Eliminate setSpan calls by using all the provided methods trough the StyleEZ interface.
Chain multiple spans with a fluent style
By using both the ContentEZ and StyleEZ interface it removes unnecessary methods from the autocomplete form, and thus it removes clutter.
Allows different ways of adding content (String, String Resource and Formatted String)
By default it does INCLUSIVE_INCLUSIVE to all the spans
After calling any of the inclusive/exclusive methods, all the next methods will be using that flag until apply is called or another flag is used
You can create your own locator by extending the Locator interface
