我试图在asynctask中使用json解析加载数据，但加载不正确有时没有得到完整的数据有时是说android.os.main线程我尝试了很多次，但我仍然遇到了问题我把我的代码&此处为logcat

您从FlightListBack$4.onClick调用JsonParser.getJSONFromUrl(您在此处添加的匿名点击监听器：buttontime.setOnClickListener(new OnClickListener{..})
在这个JsonParser.getJSONFromUrl中，您执行一个http请求，然后在主线程(或UI线程)上运行，因为它是从onClick()启动的。您应该重新构造代码以在工作线程上执行http请求(例如，使用AsyncTask)，就像在另一种情况下调用JsonParser.getJSONFromUrl.一样
在onCreate()中添加此代码；方法，然后再执行AsynckTask
StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
.detectDiskReads()
.detectDiskWrites()
.detectNetwork() // or .detectAll() for all detectable problems
.penaltyLog()
.build());
StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
.detectLeakedSqlLiteObjects()
.detectLeakedClosableObjects()
.penaltyLog()
.penaltyDeath()
.build());
但请记住，这段代码对开发阶段很有帮助，您必须删除它，并且在生产阶段不要使用任何网络操作。
