#AwesomeValidation

##Introduction Implement validation for Android within only 3 steps. Developers should focus on their awesome code, and let the library do the boilerplate. And what's more, this could help keep your layout file clean.

##Steps

1. Declare validation style;
2. Add validations;
3. Set a point when to trigger validation.

##Sample code

// Step 1: designate a style
AwesomeValidation mAwesomeValidation = new AwesomeValidation(BASIC);
// or
AwesomeValidation mAwesomeValidation = new AwesomeValidation(COLORATION);
mAwesomeValidation.setColor(Color.YELLOW);  // optional, default color is RED if not set
// or
AwesomeValidation mAwesomeValidation = new AwesomeValidation(UNDERLABEL);
mAwesomeValidation.setContext(this);  // mandatory for UNDERLABEL style
// or
AwesomeValidation mAwesomeValidation = new AwesomeValidation(TEXT_INPUT_LAYOUT);

// Step 2: add validations
// support regex string, java.util.regex.Pattern and Guava#Range
// you can pass resource or string
mAwesomeValidation.addValidation(activity, R.id.edt_name, "[a-zA-Z\\s]+", R.string.err_name);
mAwesomeValidation.addValidation(activity, R.id.edt_tel, RegexTemplate.TELEPHONE, R.string.err_tel);
mAwesomeValidation.addValidation(activity, R.id.edt_email, android.util.Patterns.EMAIL_ADDRESS, R.string.err_email);
mAwesomeValidation.addValidation(activity, R.id.edt_year, Range.closed(1900, Calendar.getInstance().get(Calendar.YEAR)), R.string.err_year);
mAwesomeValidation.addValidation(activity, R.id.edt_height, Range.closed(0.0f, 2.72f), R.string.err_height);
// or
mAwesomeValidation.addValidation(editText, "regex", "Error info");

// to validate TextInputLayout, pass the TextInputLayout, not the embedded EditText
AwesomeValidation mAwesomeValidation = new AwesomeValidation(TEXT_INPUT_LAYOUT);
mAwesomeValidation.addValidation(activity, R.id.til_email, Patterns.EMAIL_ADDRESS, R.string.err_email);

// to validate the confirmation of another field
String regexPassword = "(?=.*[a-z])(?=.*[A-Z])(?=.*[\\d])(?=.*[~`!@#\\$%\\^&\\*\\(\\)\\-_\\+=\\{\\}\\[\\]\\|\\;:\"<>,./\\?]).{8,}";
mAwesomeValidation.addValidation(activity, R.id.edt_password, regexPassword, R.string.err_password);
// to validate a confirmation field (don't validate any rule other than confirmation on confirmation field)
mAwesomeValidation.addValidation(activity, R.id.edt_password_confirmation, R.id.edt_password, R.string.err_password_confirmation);

// Step 3: set a trigger
findViewById(R.id.btn_done).setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        mAwesomeValidation.validate();
    }
});

// Optional: remove validation failure information
findViewById(R.id.btn_clr).setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        mAwesomeValidation.clear();
    }
});

##Import as dependency For Gradle it's so easy: just add below compile line to your module's build.gradle (it's available on JCenter).

dependencies {
    compile 'com.basgeekball:awesome-validation:2.0'
}
