android 判断EditText中输入的值是数字、字母还是汉字的方法

String text = edInput.getText().toString();       Pattern p = Pattern.compile("[0-9]*");        Matcher m = p.matcher(text);        if(m.matches() ){        Toast.makeText(Main.this,"输入的是数字", Toast.LENGTH_SHORT).show();        }        p=Pattern.compile("[a-zA-Z]");       m=p.matcher(text);       if(m.matches()){        Toast.makeText(Main.this,"输入的是字母", Toast.LENGTH_SHORT).show();       }       p=Pattern.compile("[\u4e00-\u9fa5]");       m=p.matcher(text);       if(m.matches()){        Toast.makeText(Main.this,"输入的是汉字", Toast.LENGTH_SHORT).show();       }
