EditText 的 文本输入监听 TextWatcher使用方法

nickCon.addTextChangedListener(mtWatcher);

private class MyTextWatcher implements TextWatcher{
String beforeStr="";

/**  这个是每个字符改变前的  字符串*/
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
beforeStr=s+"";
Log.d(TAG, "beforeTe = "+beforeStr);

}

@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
Log.d(TAG, "onTextCh = "+s);

}

@Override
public void afterTextChanged(Editable s) {
Log.d(TAG, "Editable = "+s);
if (s.toString().equals(nickNameRes)) {
titleSave.setEnabled(false);
}else {
titleSave.setEnabled(true);
}
}

}
