【问题】
之前已经遇到过一次，TabHost在addTab时挂掉：
现在又遇到了：
1 | 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
1 2 3 4 5 6 7 8 9 10 11 12 | 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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | @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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | @Overridepublic 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。
