我有一个带有片段类的Tab布局，里面有一个listview和一个微调器。列表视图中的所有数据都是从我的数据库中填充的。 如何通过在我的微调器中选择按ID获取的项目来更改列表视图中的数据？
以下是我的JSON文件示例
{
"game_response": [{
"EID": "1",
"teamone": "RRR",
"teamtwo": "TTT",
"teamonepts": "69",
"teamtwopts": "61",
"e_name": "Basketball",
"e_gender": "Male"
}, {
"EID": "2",
"teamone": "AAA",
"teamtwo": "BBB",
"teamonepts": "61",
"teamtwopts": "52",
"e_name": "Basketball",
"e_gender": "Female"
}, {
"EID": "3",
"teamone": "CCC",
"teamtwo": "DDD",
"teamonepts": "56",
"teamtwopts": "38",
"e_name": "Football",
"e_gender": "Male"
}]
}
我的微调器中的每个数据的 EID是唯一ID 。当我选择＆＃34; Basketball Female＆＃34;时，如何才能在列表视图中显示来自EID 2的所有数据？来自我的微调器？
这是我的安卓代码
