Never mind. Figured it out.
EditText txtInput = (EditText) findViewById(R.id.txtInput);
txtInput.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable edt) {
String temp = edt.toString();
int posDot = temp.indexOf(".");
if (posDot <= 0) return;
if (temp.length() - posDot - 1 > 2)
{
edt.delete(posDot + 3, posDot + 4);
}
}
public void beforeTextChanged(CharSequence arg0, int
arg1, int
arg2, int arg3) {}
public void onTextChanged(CharSequence arg0, int arg1,
int arg2,
int arg3) {}
});
