android - How to use EditText onTextChanged event when I press the number?

Question

I have an EditText with "text = 0.00". When I press the number 3, it should be like 0.03 and the second time when I press the number 5, the text should be 0.35. And 35.0, 35.09 like this. The EditText initially has the value of 0.00.

These are all done with the same EditText.

How do I achieve this? I have tried using addTextChangedListener() with TextWatcher().

You can also try this:

EditText searchTo = (EditText)findViewById(R.id.medittext);
searchTo.addTextChangedListener(new TextWatcher() {
    @Override
    public void afterTextChanged(Editable s) {
        // TODO Auto-generated method stub
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        // TODO Auto-generated method stub
    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        doSomething();
    } 
});
