textwatcher

What I want I have an EditText, where the user can enter a value, such as 10.40. Once the user is done editing I am formatting his input to a currency, for instance the above mentioned value would get formatted to $10.40 (in the case of Locale.US). And I display that result in the same EditText that the user previously edited. Problem Because I am going to format (i.e. modify) his input, I need to know when he's done (so my formatting does not interfer with his ongoing input). What I tried TextWatcher is not an option, since it fires on every single edit, hence when the user enters one, zero,

Instead of 5118710, it should be 511-8710 . I'd like to add a dash after the user the user inputted 3 digits already in the EditText. The maximum length of the EditText is 7 digits only. After I figured out the above problem, I've got stuck in coding again. When I already inputted 3 digits, it appends dash (that's what I'd like to happen) but my problem here is that the next 3 digits also appends dash (Like this: 511-871- ) ... Please help me with this. thanks! txt_HomeNo.addTextChangedListener(new TextWatcher() { @Override public void onTextChanged(CharSequence s, int start, int before, int

I use the TextWatcher for text change event.

In my Android application I need to implement a TextWatcher interface to implement onTextChanged . The problem I have is, I want to update the same EditText With some extra string. When I try to do this the program terminates. final EditText ET = (EditText) findViewById(R.id.editText1); ET.addTextChangedListener(new TextWatcher() { @Override public void onTextChanged(CharSequence s, int start, int before, int count) { try { ET.setText("***"+ s.toString()); ET.setSelection(s.length()); } catch(Exception e) { Log.v("State", e.getMessage()); } } @Override public void beforeTextChanged

I have an edittext, and a textwatcher that watches if SPACE arrived or not. If its a SPACE I would like to delete that instantly. Or if its a space I want to make sure it doesnt appear but indicate somehow (seterror, toast) for the user that space is not allowed. edittext.addTextChangedListener(new TextWatcher() { public void afterTextChanged(Editable s) { //---// } public void beforeTextChanged(CharSequence s, int start, int count, int after) {} public void onTextChanged(CharSequence s, int start, int before, int count) {} }); I cannot define onkeydown in the afterTextChaned method, since it

I have an annoying problem with TextWatcher. i've been searching the web but couldnt find anything. appreciate if someone could assist me. For some reason the calls to the TextWatcher events upon one text change are erratic. sometimes they are being triggered once (like they should be), sometimes twice, and sometimes 3 times. have no idea why, the whole thing is very straight forward. also sometimes the Editable parameter on afterTextChanged() returns empty values in toString() and length(). code is below: private TextWatcher mSearchAddressTextChangeListener = new TextWatcher() { @Override
