解决方案如下:

主线程建Handler

private class  MainHandler  extends Handler{

/**

* Subclasses must implement this to receive messages.

*/

public void handleMessage(Message msg) {

switch(msg.what){

case 1:

btnRight.setVisibility(View.INVISIBLE);

btnRight.setText("");

break;

default:

break;

}

}

}

Message msg = new Message();

msg.what = 0;

mainHandler.sendMessage(msg);

这样就ok了
