  android 开发常出现类似的错误。

  原因是：View控件的操作只能在主线程操作。 如果改成在其他线程中处理就会报上面的错误。

  eg:

new Thread(){
				public void run() {
					Message msgMessage = xHandler.obtainMessage(what);
					xHandler.sendMessage(msgMessage);
                                        testView.setVisibility(View.GONE);
				}
			}.start();
