Android how to resize a text inside an EditText

I have an EditText. I would like to resize the text inside the EditText, if the length of the text is bigger than 10 for example.

How to do this?

Thank you. Appreciate!

You may prefer using a TextWatcher instead of an OnKeyListener (which obviously targets hardware keys) :

    final float size1 = 30, size2 = 15;

    final EditText edit = new EditText(this);
    edit.setTextSize(size1);

    edit.addTextChangedListener(new TextWatcher() {

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            if(s.length() > 10) {
                edit.setTextSize(size2);
            }
        }

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

        @Override
        public void afterTextChanged(Editable s) {
        }
    });

Please try:

if(myEditText.getText().toString().lenght() > 10)
{
        myEditText.setTextSize(6);
} 
else 
{
        myEditText.setTextSize(10);
}

This should do the trick :

final EditText et = (EditText) findViewById(R.id.editTextId);
et.setOnKeyListener(new OnKeyListener() {
    @Override
    public boolean onKey(View v, int keyCode, KeyEvent event) {
        if(et.getText().length()>10) {
            et.setTextSize(newValue);
        } else {
            et.setTextSize(oldValue);
        }
        return false;
    }
});
