JSON，无法使用key显示所需信息！

Question

我正在使用 android 1.5，目前正在研究 JSON 相关的东西。我在字符串变量str中拥有此信息

{
"UserInfo":
    [
    {"LastName":"b","FirstName":"a","Gender":"Male","User: ":1},
    {"LastName":"b","FirstName":"a","Gender":"Male","User: ":2},
    {"LastName":"b","FirstName":"a","Gender":"Male","User: ":3}
    ]
}
{
"Info":
    [
    {"LastName":"d","FirstName":"c","Gender":"Male","User: ":5},
    {"LastName":"d","FirstName":"c","Gender":"Male","User: ":6},
    {"LastName":"d","FirstName":"c","Gender":"Male","User: ":7},
    {"LastName":"d","FirstName":"c","Gender":"Male","User: ":8},
    {"LastName":"d","FirstName":"c","Gender":"Male","User: ":9},
    ]
}

，我在str中拥有所有这些信息，现在通过使用键（即UserInfo和Info）我想使用信息来显示其所有元素。我该怎么做？ 谢谢！
