EditText 在textWatcher中监听的实现--及二个正则表达式

@Override
public void afterTextChanged(Editable s) {
// Log.w("linsen","after!!"+s);
if(s.length()>0){
final String str = s.toString();
if (!str.matches("^[0-9#*]+$")) {

mHandler.post(new Runnable() {

@Override
public void run() {
numtv.setText(str.replaceAll("[^0-9#*]", ""));
numtv.setSelection(mSelection);
}
});

}else{

}
}
}
