    setContentView(R.layout.activity_main);

    et=(EditText) findViewById(R.id.et);

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count,
                int after) {

        public void onTextChanged(CharSequence s, int start, int before,
                int count) {
        }
        @Override
        public void afterTextChanged(Editable s) {
            et.removeTextChangedListener(tw);
            et.setText(Math.random()+"");//add your logic here 
            et.addTextChangedListener(tw);
        }};
        et.addTextChangedListener(tw);
}
