How to check if there are spaces inside editText and fill them programmatically

Question

I want to check if there is a space or not between letters and add a space if there is or not, remove if there are to many. Is there an easy way to achieve this?

What I am currently doing checking for postcode however I want to add spaces if there is no spaces e.g. M11SS make it M1 1SS and delete starting spaces and ending spaces

if (a.isEmpty(txtJobPostcode)) {
    Toast.makeText(getContext(), "Please enter a postcode", Toast.LENGTH_LONG).show();
    return;
}
if(txtJobPostcode.getText().toString().matches("^[A-Z]{1,2}[0-9R][0-9A-Z]? [0-9][ABD-HJLNP-UW-Z]{2}$")){
    Log.d("NOTICE", String.valueOf(txtJobPostcode));
} 
else {
    Toast.makeText(getContext(), "Please enter a valid postcode", Toast.LENGTH_LONG).show();
    return;
}

Try to consider: TextWatcher class in Android sdk.

You can find the documentation by the link:
