您的JSON本身是错误的，请尝试为您的JSONArray提供密钥，

{
"data": [{
    "transaction_name": "total_fare",
    "unit": "Rs",
    "label": "Bill Amount",
    "value": 250,
    "additional_details": "4 Rides"
}, {
    "transaction_name": "incentives",
    "label": "Incentives",
    "value": 50,
    "additional_details": ""
}, {
    "transaction_name": "fees",
    "label": "Fees",
    "value": -20,
    "additional_details": "Rs 5 on each ride"
}, {
    "transaction_name": "device_deduction",
    "label": "Device Deduction",
    "value": -20,
    "additional_details": ""
}, {
    "transaction_name": "tax",
    "label": "Device Deduction",
    "value": -20,
    "additional_details": ""
}, {
    "transaction_name": "device_deduction",
    "label": "Device Deduction",
    "value": -20,
    "additional_details": ""
}],
"footer": {
    "transaction_name": "total_earning_net",
    "label": "Total Earnings",
    "value": 200,
    "additional_details": "Rounding Off"
  }

}

如果json字符串没有键名，则无法使用Gson解析json
