连云港网站建设 连云港网站制作南宁seo团队哪家好

一、前言：这个代码也是借鉴别人写的，我也看不太懂。为了方便日后用到就用这篇文章记录一下。

二、代码展示

 /*** 禁止EditText输入空格** @param editText*/public static void setEditTextInhibitInputSpace(EditText editText) {editText.addTextChangedListener(new TextWatcher() {@Overridepublic void onTextChanged(CharSequence s, int start, int before,int count) {if (s.toString().contains(" ")) {String[] str = s.toString().split(" ");String str1 = "";for (int i = 0; i < str.length; i++) {str1 += str[i];}editText.setText(str1);editText.setSelection(start);}}@Overridepublic void beforeTextChanged(CharSequence s, int start, int count,int after) {}@Overridepublic void afterTextChanged(Editable s) {}});}/*** 禁止EditText输入特殊字符** @param editText*/public static void setEditTextInhibitInputSpeChat(EditText editText) {InputFilter filter = new InputFilter() {@Overridepublic CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {String speChat = "[`~!@#$%^&*()+=|{}':;',\\[\\].<>/?~！@#￥%……&*（）——+|{}【】‘；：”“’。，、？]";Pattern pattern = Pattern.compile(speChat);Matcher matcher = pattern.matcher(source.toString());if (matcher.find()) return "";else return null;}};editText.setFilters(new InputFilter[]{filter});}

三、总结：以上代码可以直接复用
