Answer 1

XMLで

：

<EditText 
     android:id="@+id/edit_blood_group" 
     style="@style/edit_text" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:hint="@string/msg_blood_group" 
     android:maxLength="3" 
     android:digits="aboABO+-"/> 

検証コードで

：のstrings.xml

あるいは

<string-array name="blood_groups"> 
     <item>O+</item> 
     <item>O-</item> 
     <item>A+</item> 
     <item>A-</item> 
     <item>B+</item> 
     <item>B-</item> 
     <item>AB+</item> 
     <item>AB-</item> 
    </string-array> 

で

public static boolean isBloodGroupValid(String bloodGroup, Context context){ 
     if(bloodGroup != null) { 
      String[] bloodGroups = context.getResources().getStringArray(R.array.blood_groups); 
      int len = bloodGroups.length; 
      for (int i = 0; i < len; i++) { 
       if(bloodGroup.equalsIgnoreCase(bloodGroups[i])) 
        return true; 
      } 
     }return false; 
    } 

、また前とスピナーを定義することができ配列からアイテムを取り込み、誰もそれがないようにする無効な値を入力できます。

例、年齢は18〜24歳の間にあるかどうかを確認するには：

public static boolean isDOBInRange(String dateStr) { 
     try { 
      Calendar calMin = Calendar.getInstance(); 
      calMin.add(Calendar.YEAR, -Constants.MAX_AGE_LIMIT); //24 
      Date dateStart = calMin.getTime(); 

      Calendar calMax = Calendar.getInstance(); 
      calMax.add(Calendar.YEAR, -Constants.MIN_AGE_LIMIT); //18 
      Date dateEnd = calMax.getTime(); 

      DateFormat format = new SimpleDateFormat("dd-MM-yyyy"); 
      Date date = format.parse(dateStr); 

      if (date != null && dateStart != null && dateEnd != null) { 
       if (date.after(dateStart) && date.before(dateEnd)) { 
        return true; 
       } else { 
        return false; 
       } 
      } 
      return false; 
     } catch (Exception e) { 
      return false; 
     } 
    }
