Android disable space only for Edittext

Question

In my android application I need to disABLE Spacebar only. But I didn't find a solution for this problem. I need to disable space bar and when user enter space should not work, special characters, letters, digits and all other should work. What I tried is,

etPass.addTextChangedListener(new TextWatcher() {

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {
                // TODO Auto-generated method stub
                String str = s.toString();
                if(str.length() > 0 && str.contains(" "))
                {
                    etPass.setError("Space is not allowed");
                    etPass.setText("");
                }
            }

            @Override
            public void beforeTextChanged(CharSequence s, int start, int count,
                                          int after) {
                // TODO Auto-generated method stub

            }

            @Override
            public void afterTextChanged(Editable s) {
                // TODO Auto-generated method stub

            }
        });

But the problem here is once space comes whole text is deleting. I removed

etPass.setText("");

this line, so at that time error message is showing, but at that time user can still able to type space. But what I need is user shouldn't able to type the space.

This solution worked for me :

android:digits="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890"
android:inputType="textFilter"

Add it into edit text in the XML file
