There is an event on android called addTextChangedListener for the EditText with the methods afterTextChanged that will do an action when the text is changed, beforeTextChanged which will do an action before the text is changed and onTextChanged that will do a real-time action, and using the method of converting to $ post format https://stackoverflow.com/questions/2379221/java-currency-number-format you can make the following way:

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) {
        searchTo.setText(formatDecimal(Float.parseFloat(searchTo.getText())));
    } 
});

Method of conversion to cash:

public String formatDecimal(float number) {
  float epsilon = 0.004f; // 4 tenths of a cent
  if (Math.abs(Math.round(number) - number) < epsilon) {
     return String.format("%10.0f", number); // sdb
  } else {
     return String.format("%10.2f", number); // dj_segfault
  }
}
