【已解决】Android中再次遇到TabHost在addTab时挂掉：android.view.ViewRootImpl$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.

【问题】

之前已经遇到过一次，TabHost在addTab时挂掉：

【已解决】Android中用TabHost去addTab添加TAB结果出错：Unable to start activity ComponentInfo: android.content.res.Resources$NotFoundException: Resource ID #0×0

现在又遇到了：

mTabHost.addTab(singleTab);

时挂掉：

【解决过程】

1.后来自己摸索，改为：

（1）把之前的generateMainTabUI，去掉Thread

 private void generateMainTabUI(){
//	 Thread thread = new Thread(new Runnable() {
//
// @Override
// public void run() {
        ......
       mTabHost.addTab(singleTab); 
   }
// }}); 
//
//	 thread.start();
 }

（2）mHandler中正常去调用generateMainTabUI

 @SuppressLint("HandlerLeak")
 private Handler mHandler = new Handler() {
  public void handleMessage(Message msg) {
   switch (msg.what) {
   ......
   case MESSAGE_GEN_MAIN_TAB_UI:
    if(null != msg){
     generateMainTabUI();
    }
    break;
   ......

  };
 };

（3）onEvent中正常去发message，以使得后续可以正常自行到上面的handler

 @Override
 public void onEvent(String eventName, Object data, IEventResult result) {
  if (eventName.equals(EventName.BLLInitDeviceModelComplete)) {
   ......
   
   if(result.IsSuccess()){
    ......
    Message msg = new Message();
    msg.what = MESSAGE_GEN_MAIN_TAB_UI;
    msg.obj=deviceModel;
    mHandler.sendMessage(msg);
   }
   else{
    ......
   }
  }
  ......
 }

【总结】

大概的感觉是：

Handler中，本身是其他线程，不能再次new线程了，否则去处理UI的事情的时候，会由于新new出来的线程，不是原先的UI的线程，没有所属权，所以会导致挂掉。
