android 线程 弹出对话框


android 线程 弹出对话框



多线程,在线程中用handler实现弹出对话框

   Handler handler = new Handler()
{
public void handleMessage(Message paramMessage)
{
comm.showDialog("添加成功!", ShopAddActivity.this);
}
};



new Thread(){
    @Override
    public void run()
    {


handler.sendMessage(localMessage);

}.start();
                 

要用handler,否则会报错Can't create handler inside thread that has not called Looper.prepare() 因为在Android中不能在子线程中来刷新UI线程,而可以在子线程中添加hander来发送消息更新线程。
