   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();  
     }
