android "Only the original thread that created a view hierarchy can touch its v"
android在新的线程中操作view时出现的异常如题， 可以用如下操作解决。

final Handler mHandler = new Handler() {public void handleMessage(Message msg) {super.handleMessage(msg);//update your view function}};           new Thread( new Runnable() {            public void run() {              //download data function            mHandler.sendMessage(mHandler.obtainMessage());             } }).start();
