只要三個步驟就能夠輕松實現復雜繁瑣的表單驗證。

Steps

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

示例代碼

// 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

// Step 2: add validations
// support regex string or 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_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");

// 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();
    }
});
