注 ：前の質問で述べたように、指定されたJSON文字列は正しい形式である必要があります。つまり、各オブジェクト（ログイン、アカウント）のキーを持っているか、単一の配列（入力）にある必要があります。私は両方のオプションの解決策を提供しています。
初心者、私は2つの別々のメソッドを提供しているので、単一のJSON文字列の2つのオブジェクトまたはJSON配列の2つのオブジェクトのいずれかを構築する方法に応じて、着信JSON文字列を処理できます。
あなたはあなたの解決策を選ぶことができます:)
コードを試してみてください。さらにサポートが必要な場合はお知らせください。回答を受け入れてください。
オプション1：単一のJSON文字列内の2つのオブジェクト
{
"login":{
"error":false,
"user":{
"br_code":12,
"mem_id":13,
"username":"novalyn",
"email":"[email protected]",
"created_at":"2016-07-22 09:05:21"
}
},
"accounts":{
"error":false,
"sl_summ":[
{
"sl_desc":"PA : Savings Account",
"tr_date":"2015-08-17",
"actual_balance":"483.67",
"available_balance":"483.67"
},
{
"sl_desc":"PA : Savings - Cash Bond",
"tr_date":"2015-08-28",
"actual_balance":"10129.43",
"available_balance":"10129.43"
}
]
}
}
オプション2：単一のJSON配列文字列内の2つのオブジェクト
{
"input":[
{
"error":false,
"user":{
"br_code":12,
"mem_id":13,
"username":"novalyn",
"email":"[email protected]",
"created_at":"2016-07-22 09:05:21"
}
},
{
"error":false,
"sl_summ":[
{
"sl_desc":"PA : Savings Account",
"tr_date":"2015-08-17",
"actual_balance":"483.67",
"available_balance":"483.67"
},
{
"sl_desc":"PA : Savings - Cash Bond",
"tr_date":"2015-08-28",
"actual_balance":"10129.43",
"available_balance":"10129.43"
}

PHPコードを実行するために使用できるすべての内部PHPファイルにアクセスできないため、すべての関数呼び出しのほとんどを、サンプル応答ペイロードで共有されるハードコードされた値に置き換えました。これは、OPTION1形式でJSONオブジェクトを生成するためのコードです。
つまり、$ responseのすべてのサブ属性の前に["login"]と["accounts"]を追加して、正しいJSONオブジェクトにグループ化し、上記で解析できる2つのJSONオブジェクトを作成する必要があります。 android共有コード。
