ArrayIndexOutofBoundException當第二個值是不存在的JSON解析

-1

我得到以下ArrayoutofBound例外：ArrayIndexOutofBoundException當第二個值是不存在的JSON解析

Process: com.lifeontrack, PID: 1379 
java.lang.ArrayIndexOutOfBoundsException: length=1; index=1

代碼：

String numberone = ""; 
String numbertwo = ""; 

JSONArray phoneArray = jsonObject.getJSONArray("phone"); 
JSONObject cit = phoneArray.getJSONObject(0); 
String phoneNumbers = ""; 
for (int count=1; count <= phoneArray.length(); count++) 
{ 
    if (phoneNumbers.length() == 0) 
     phoneNumbers += phoneArray.getJSONObject(count-1).getString("value"); 
    else 
     phoneNumbers += ","+ phoneArray.getJSONObject(count-1).getString("value"); 
} 

System.out.println("Phonenumbers" + phoneNumbers); 
String[] numbers = phoneNumbers.split(","); 
numberone = numbers[0]; 
numbertwo = numbers[1]; 

View.setText(numberone); 
View.setText(numbertwo); 

Button btn_home_phone_viewCg = ((Button) rootView.findViewById(R.id.btn_home_phone_viewCg)); 
btn_home_phone_viewCg.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     if(!Objects.equals(numberone, "")){ 
      Uri numberoneuri = Uri.parse("tel:"+numberone); 
      Intent callIntent = new Intent(Intent.ACTION_DIAL, numberoneuri); 
      startActivity(callIntent); 
     } 
    } 
}); 

Button btn_home_phone_viewCgtwo = ((Button) rootView.findViewById(R.id.btn_home_phone_viewCgtwo)); 
btn_home_phone_viewCgtwo.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     if(!Objects.equals(numbertwo, "")){ 
      Uri numbertwouri = Uri.parse("tel:"+numbertwo); 
      Intent callIntent = new Intent(Intent.ACTION_DIAL, numbertwouri); 
      startActivity(callIntent); 
     } 
    } 
});

當代碼運行輸出：Phonenumbers : 9784513234,9487516132 當代碼打破輸出：Phonenumbers : 9784513234,

我相信當String「numbertwo」沒有值的時候會發生這種情況，這可能嗎？如果是的話如何處理這種情況？

檢查你的JSON所得到的響應，bcoz WRT代碼它應該工作... –

一塊蛋糕。

if(numbers.length > 0){ 
    numberone = numbers[0]; 
} 

if(numbers.length > 1){ 
    numbertwo = numbers[1]; 
}

說明：

ArrayIndexOutOfBoundsException當您嘗試在該位置訪問值超出數組範圍的火災。

呃.... 。它的長度不是長度 – Denny

kek ..謝謝.... –

在JSON中，您應該將phonenumber作爲字符串或數組，因爲在JSON解析中，'read'會將下一個數字視爲JSON對象。電話號碼想：

phonenumber: {'onenumber','secondnumber'}

將解決ArrayIndexOutOfBound異常

JSONArray phoneArray = jsonObject.getJSONArray("phone"); 
    //loop your jsaonArray 
    for(int count=0; count<phoneArray.length(); count++){ 
     JSONObject cit = phoneArray.getJSONObject(count); 
     //do your stuff here 
    }
