नोट :जैसा कि पिछले प्रश्न में बताया गया है, दी गई JSON स्ट्रिंग को सही प्रारूप में होना चाहिए यानी या तो प्रत्येक ऑब्जेक्ट (लॉगिन, अकाउंट) के लिए एक कुंजी होनी चाहिए या उन्हें एक ही सरणी (इनपुट) में रखना चाहिए। मैं दोनों विकल्पों का समाधान दे रहा हूं।
नौसिखिया, मैं आपको 2 अलग-अलग तरीके प्रदान कर रहा हूं ताकि आप आने वाली JSON स्ट्रिंग को संभाल सकें, इस पर निर्भर करते हुए कि आप इसे कैसे बनाते हैं या तो सिंगल JSON स्ट्रिंग में 2 ऑब्जेक्ट या JSON सरणी में 2 ऑब्जेक्ट।
आप अपना समाधान चुन सकते हैं :)
कोड आज़माएं, अगर आपको और मदद चाहिए तो मुझे बताएं और जवाब स्वीकार करें।

"tr_date":"2015-08-28",

मेरे पास उन सभी आंतरिक PHP फ़ाइलों तक पहुंच नहीं है जिनका उपयोग मैं आपके PHP कोड को चलाने के लिए कर सकता हूं, इसलिए मैंने नमूना प्रतिक्रिया पेलोड में साझा किए गए हार्ड कोड वाले मानों के साथ सभी फ़ंक्शन कॉलों को बदल दिया। यहाँ OPTION1 प्रारूप में JSON ऑब्जेक्ट उत्पन्न करने के लिए कोड है।
संक्षेप में, आपको $response में सभी उप विशेषताओं के आगे ["लॉगिन"] और ["खाते"] जोड़ना होगा ताकि उन्हें सही JSON ऑब्जेक्ट में समूहीकृत किया जा सके और आपके पास दो JSON ऑब्जेक्ट होंगे जिन्हें ऊपर से पार्स किया जा सकता है एंड्रॉइड साझा कोड।
