Android disable space only for Edittext

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("");, 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
