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.
