Android textchange listener
<p>what i want to do is, if text is null then not to call text change listener.</p>

<pre><code>public void afterTextChanged(Editable s) {
                if(et1.getText().toString().length() == 0){
                    et1.removeTextChangedListener(watcher);
                    et1.setText("");
                }
            }
</code></pre>

<p>This does not work why?</p>
