android中EditText输入框处理一些特殊符号

如下代码是禁止EditText输入一些特殊符号

public class EditTextInputFilter {
    /**
     * 禁止EditText输入空格
     *
     * @param editText
     */
    public static void setEditTextInhibitInputSpace(EditText editText) {
        InputFilter filter = new InputFilter() {
            @Override
            public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
                if (source.equals(" ")) {
                    return "";
                } else {
                    return null;
                }
            }
        };
        editText.setFilters(new InputFilter[]{filter});
    }

    /**
     * 禁止EditText输入特殊字符
     *
     * @param editText
     */
    public static void setEditTextInhibitInputSpeChat(EditText editText) {

        InputFilter filter = new InputFilter() {
            @Override
            public 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});
    }
}
