final EditText edt = (EditText) findViewById(R.id.editText1);

    edt.setText("http://");
    Selection.setSelection(edt.getText(), edt.getText().length());


    edt.addTextChangedListener(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) {
                // TODO Auto-generated method stub

            }

            @Override
            public void afterTextChanged(Editable s) {
                if(!s.toString().startsWith("http://")){
                    edt.setText("http://");
