textwatcher

I would like to begin by saying I have little to no android experience, this is my first ever project within android and my teacher isn't quite teaching, so I apologize for any excessive ignorance. To explain before I go any further: The goal of my app is essentially the ability to bank how many hours you have spent doing certain activities, record the times, and then display them in graphs. What I'm currently working on is creating text fields that will allow the user to type in how many hours they spent in each activity and then add them up to total hours spent, and I want this to be done

I am having a problem with setError() on EditText . When an activity is opened, it checks if certain fields are empty and sets error message on them if true. However, the exclamation mark icon is only displayed in case I write some text in field and then delete it. If I lose focus on that field, the icon will disappear again. Both fields Naam and Telefonnumer have this validation. I use Android 2.2.2 SDK and the application is run on Nexus 7 with latest updates. I have Util class: public class Util { private static String TAG = "Util Class"; public static boolean editTextIsEmpty(EditText

I need to detect text changes in an EditText. I've tried TextWatcher, but it doesn't work in a way I would expect it to. Take the onTextChanged method: public void onTextChanged( CharSequence s, int start, int before, int count ) Say I have the text "John" in already in the EditText. If press another key, "e", s will be "Johne", start will be 0, before will be 4, and count will be 5. The way I would expect this method to work would be the difference between what the EditText previously was, and what it's about to become. So I would expect: s = "Johne" start = 4 // inserting character at index

I have a handler that is a TextWatcher and i dont know how to get the View that has changed text. Here is my handler: TextWatcher handler = new TextWatcher() { @Override public void onTextChanged(CharSequence s, int start, int before, int count) { // TODO Auto-generated method stub } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { oldText = s.toString(); } @Override public void afterTextChanged(Editable s) { //v.setText("afterTextChanged"); } }; Note the commented part, that is what i want, to get the View from the EditText that has triggered the

I am working on a android app and I have an EditText where user can input numbers. I want to format the number using different currency formats (say ##,##,###) and I want to do it on the fly, ie when user enter each digit(not when enter is pressed). I googled around, and came across TextWatcher which I first found promising, but it turned out to be an absolute pain. I am debugging my code on a HTC Desire phone which only has a soft keyboard. Now I want to get a callback when user press numbers (0 to 9) , del (backspace) key and enter key. From my testing I found these (atleast on my phone) 1)
