A simple library which can be used to validate edittext in android for empty values.

GRADLE :-

Add it in your root build.gradle at the end of repositories:

allprojects {
	repositories {
			maven { url 'https://jitpack.io' 
			}
		     }
	      }

Add it in your app build.gradle at the end of repositories:

dependencies {
	        implementation 'com.github.manishSharmaJmd:Validator:1.5'
	     }

How to use it :-

Step 1 :- Call Validator.attachValidator(EditText[] editTextAr, TextWatcher textWatcher, View.OnFocusChangeListener onFocusChangeListener)

editTextAr = Array of Edittext that required validation.
textWatcher = Pass TextWatcher callback for lookup text change.
onFocusChangeListener = Pass OnFocusChangeListener callback to get focus info.

Setup 2 :- Check for success result Validator.isValidated()

Advanced Usage :-

Step 1 :-

Inject into Activity. It will pick all edittext automatically.

Validator.injectActivity(Activity activity,  TextWatcher textWatcher,  View.OnFocusChangeListener onFocusChangeListener);
 

Inject into Fragment. It will pick all edittext automatically.

Validator.injectFragment(Fragment fragment,  TextWatcher textWatcher,  View.OnFocusChangeListener onFocusChangeListener)

Setup 2 :-

Check for success result Validator.isValidated()

To change error style, Pass resource id like this :-

Validator.setErrorResource(int resId)
