android 利用线程刷新UI方法

新建线程
new Thread(new Runnable()

线程方法：
public void run()

private void setAddWidgetEnabled(boolean enabled,boolean iscomplete) {
        mbtn_contactin_begin.setEnabled(enabled);
        if (iscomplete) {
            new Thread(new Runnable() {
                public void run() {
                    runOnUiThread(new Runnable() {
                        public void run() {

                            mbtn_contactin_begin
                                    .setText(getString(R.string.aio_ime_action_label));
                            mbtn_contactin_begin.setEnabled(false);
                        }
                    });
                }
            }).start();
        }

    }      

 注意：runOnUiThread是activity.runOnUiThread,并非Context.runOnUiThread.
