这是我试图解析的json。
{ "data": {
"judul_push":"jdl",
"pesan_push":"Isi",
"image_push": "xxx.png",
"icon_kecil": "xxx.png",
"icon_besar": "xxx.png",
"is_background":true,
"tipe_push":1,
"timestamp":"27-10-2016 22:51:48",
"payload":{
"IMAGE_ID":"1",
"IMAGE_TYPE":"5",
"IMAGE_NAME":"SPLASH SCREEN",
"IMAGE_PATH":"xxx.png"
}
},
"to" : "fK2iL7Ptp9I:APA91bEFxlLyEIpr-vO2Fw3VoTOY6t-38EV_Thnn_SddL17nu7E1VcjZVEgpOAE7vEKn83Cxz3q9rXAapUq-00opHbuOrcw7AwPtFtyYAFb674olwttVLuQgCIByN-i_gJJy8z6rjUi7"
}
当我尝试解析JSON对象payload时，这是我的logcat错误。

有一个类似的问题，我从抱怨角色的地方删除了JSON数据，然后手动重新输入。不知怎的，我有一个隐藏的角色。希望这会有所帮助。

我找到了答案。
答案是，首先，如果Firebase向我们发送JSON数据和包含的任何JSON对象，我们需要将JSON数据解析为字符串，然后我们需要将JSON对象（有效负载）的字符串值转换为数据类型JSON对象。最后，我们可以在JSON对象（有效负载）中获取字符串值（image_id）。
