android：inputType =“textPersonName”允许所有类型的文本输入

Question

我在我的一个AutoCompleteTextViews中使用上面的属性，但是我也可以输入特殊字符和数字。需要建议将输入类型限制为仅字母，没有数字或特殊字符。

Answer 1

EditText state = (EditText) findViewById(R.id.txtState);

                Pattern ps = Pattern.compile("^[a-zA-Z ]+$");
                Matcher ms = ps.matcher(state.getText().toString());
                boolean bs = ms.matches();
                if (bs == false) {
                    if (ErrorMessage.contains("invalid"))
                        ErrorMessage = ErrorMessage + "state,";
                    else
                        ErrorMessage = ErrorMessage + "invalid state,";

试试这个。它完美地为我服务。

EditText editText = (EditText) findViewById(R.id.editText);

editText.setFilters(new InputFilter[]{alphabetFilter, new InputFilter.LengthFilter(10)});

private InputFilter alphabetFilter = new InputFilter() { @Override public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) { for (int k = start; k < end; k++) { if (!Character.isLetter(source.charAt(k))) { return ""; } } return null; } };
