Answer 1

Create anim folder in resources and then create file named shake.xml and paste the below code

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromXDelta="0" android:toXDelta="10" android:duration="1000"
    android:interpolator="@anim/cycle_7" />

and another file cycle_7.xml

<?xml version="1.0" encoding="utf-8"?>
<cycleInterpolator xmlns:android="http://schemas.android.com/apk/res/android" android:cycles="7" />

and then in your java file

if(invalid)//check your input
{
   Animation shake = AnimationUtils.loadAnimation(Login.this, R.anim.shake);
   editText.startAnimation(shake);
}

Answer 2

If anyone is looking for a method to do what @ Priya suggested programatically, then you can try this.

public TranslateAnimation shakeError() {
        TranslateAnimation shake = new TranslateAnimation(0, 10, 0, 0);
        shake.setDuration(500);
        shake.setInterpolator(new CycleInterpolator(7));
        return shake;
}

And then:

myEditText.startAnimation(shakeError());

For vibrate use the following code.

Vibrator vibe = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);

Then, in the OnTextChanged Listener method use the following code.

vibe.vibrate(50); // 50 is time in ms

And don't forget you need to add the permission to the manifest (after the </application> tag):

<uses-permission android:name="android.permission.VIBRATE" />

Create shake.xml under anim folder

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:fromXDelta="-10"
        android:toXDelta="10"
        android:repeatCount="5"
        android:repeatMode="reverse"
        android:interpolator="@android:anim/linear_interpolator"
        android:duration="70" />
</set>

After this add animation for button. I wrote this code in Kotlin for simplicity.

button.setOnClickListener {
      button.startAnimation(AnimationUtils.loadAnimation(context, R.anim.shake)
}

You should add this listener to EditText for your desired validation,

editText.addTextChangedListener(new  TextWatcher() {

            public void onTextChanged(CharSequence s, int start, int before, int count) {
            // Write your logic here
                    if(condition satisfy)
                    // call vibrate();  
            }
            public void beforeTextChanged(CharSequence s, int start, int count,
                    int after) {
            }
            public void afterTextChanged(Editable s) {

            }
        });



        public void vibrate()
        {
                Vibrator vibrate= (Vibrator)context.getSystemService(Context.VIBRATOR_SERVICE) ;
                           vibrate.vibrate(50);
        }

Answer 6

here is code for Kotlin

private fun vibrator() {
    vibrator = getSystemService(Context.VIBRATOR_SERVICE) as Vibrator?
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        vibrator!!.vibrate(
            VibrationEffect.createOneShot(
                500,
                VibrationEffect.DEFAULT_AMPLITUDE
            )
        )
    } else {
        //deprecated in API 26
        vibrator!!.vibrate(500)
    }
}
