推荐答案

您可以使用 editText.setFilters(filter)将文本过滤器应用于 EditText ，因此使用的方法将如下所示:

You can apply text filter to your EditText by using editText.setFilters(filter), So the method used will be like the following:

text = (EditText) findViewById(R.id.text);
validate_text(text);

// the method validate_text that forces the user to a specific pattern
protected void validate_text(EditText text) {

    InputFilter[] filter = new InputFilter[1];
    filter[0] = new InputFilter() {

        @Override
        public CharSequence filter(CharSequence source, int start, int end,
                Spanned dest, int dstart, int dend) {

            if (end > start) {
                String destText = dest.toString();
                String resultingText = destText.substring(0, dstart)
                        + source.subSequence(start, end)
                        + destText.substring(dend);
                if (!resultingText
                        .matches("^\\d{1,10}(\\.(\\d{1,2})?)?")) {
                    return "";
                } 
            }

            return null;
        }
    };
    text.setFilters(filter);
}

这将迫使用户在输入数字后输入点"，并且将迫使他仅在点"之后输入两位".

This will force the user to enter "dot" after entering for digits, and will force him to enter only "two digits" after the "dot".
