Answer 1

You need to add listeners to the EditTexts and Spinners.

For the EditTexts try this:

editText1.addTextChangedListener(new TextWatcher() {
    @Override
    public void afterTextChanged(Editable s) {
        // your code here
    }

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

    @Override    
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        // your code here
    }
});

And for the Spinners try this:

spinner1.setOnItemSelectedListener(new OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
        // your code here
    }

    @Override
    public void onNothingSelected(AdapterView<?> parentView) {
        // your code here
    }
}
