Android线程切换问题？

功能：主活动中有一个百度MapView控件，在这个控件里显示现在的位置。
出现的BUG：MapView有  一定概率  不显示当前位置，而是显示默认的地图位置（天安门）一番鼓捣之后有如下发现：
     当BDLocationListener继承类的方法
             onReceiverLocation（DBLocation bdLocation） {
                      runOnUiThread（new Runnable {
                               public void run(){
                                     //逻辑
                               }
                      }）；
             }
          改成如下实现方式时
             
             onReceiverLocation（BDLocation bdLocation） {
                   //逻辑
            }
            这个BUG只出现了一次，我反复测试了几十次main_layout中只有一个<com.baicu.map.MapView/>控件，代码略
