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();
