I have created a filter listview where user will enter input via edittext and results are filtered in the listview. The code is running good but when ever i press Space button, results in the list view disappears. how can i add space in search input without dismissing the listview contents ?? Here is my current code : myListview.setTextFilterEnabled(true); edNearBy.addTextChangedListener(new TextWatcher() { public void onTextChanged(CharSequence s, int start, int before, int count) { // TODO Auto-generated method stub } public void beforeTextChanged(CharSequence s, int start, int count, int

In an application with shopping cart, I give the option to change the amount of items via an EditText which allows only numerical input. Everything works fine, except when the user changes the field and then presses the back key to hide the soft keyboard.

Thank you in advance for any responses. I am trying to have an EditText in my Android application which has different colours for different characters which are typed in.

I have some code where I need a "Create Account" button to be disabled if an editText field has less than 3 char in it. If the User enters 3 chars, then the button should enable itself so that it can be used. I have constructed the if else statement that disables the button if there are less than 3 char in the editText field, BUT on input, when the user inserts 3 char, it does not re-evaluate to see if the statement is true so the button of course stays disabled.

If the EditText is empty (i.e. there are no numbers entered) and I click the Button I have the a dialog saying: "The application has stopped unexpectedly. Please try again". Please help me. I want to show a window with some comments (for example "Insert numbers"), if the user does not write any numbers. How should I program the EditText field? How to solve this? Thanks a lot This is my onClick method: public void onClick(View v) { EditText
