做了个小程序，其中布局采用了gridview，代码如下：
public class HomeActivity extends Activity {
private TabHost mHomeTabhost;
private static final String HOME_TAG = "homedebug";
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.home);
try {
mHomeTabhost = (TabHost) this.findViewById(R.id.home_tabhost);
mHomeTabhost.setup();
Log.i(HOME_TAG, "这里");
mHomeTabhost.addTab(mHomeTabhost.newTabSpec("tab1")
.setIndicator(getResources().getString(R.string.category_title_hot))
.setContent(R.id.hot_tab));
mHomeTabhost.addTab(mHomeTabhost.newTabSpec("tab2")
.setIndicator(getResources().getString(R.string.category_title_jobSearch))
.setContent(R.id.job_tab));
mHomeTabhost.addTab(mHomeTabhost.newTabSpec("tab3")
.setIndicator(getResources().getString(R.string.category_title_career))
.setContent(R.id.article_tab));
}
catch(Exception exp) {
exp.printStackTrace();
Log.d("Exception", exp.getMessage())
}
ArrayList<HashMap<String, Object>> hotjob_list = fillList();
SimpleAdapter simAdapter = new SimpleAdapter(this, hotjob_list, R.layout.hotjob,
new String []{"company", "title"},
new int []{R.id.hotjob_company, R.id.hotjob_title});
GridView gridView = (GridView)findViewById(R.id.job_hot);
try {
gridView.setAdapter(simAdapter); //没有实例化的原因？
/*Log.i("绑定监测", "绑定完毕");*/
}
catch(Exception exp) {
exp.printStackTrace();
Log.d("gridview_Exception", exp.getMessage());
}
}
通过debug查看变量，simAdapter里面的数据填充应该是成功的，直至gridView.setAdapter(simAdapter)前程序运行正常。但是进入这一句后似乎主线程就被挂起了，无法往下执行，模拟器上的界面则停留在上一个Activity上，并一闪一闪的。
这是debug窗口的截图。
下面是logcat：

我看到这个提示threadid=1: still suspended after undo (sc=1 dc=1)，不断出现，似乎是主线程被挂起了。但是undo（sc =1 dc=1）不知道是什么意思，百度搜不到，真怪。
请各位XDJM指教，不胜感激！
------解决方案--------------------
出现了anr导致
建议LZ在这句话后面
private static final String HOME_TAG = "homedebug";
声明下private GridView gridView ;
然后onCreate 方法gridView = (GridView)findViewById(R.id.job_hot);
在来gridView.setAdapter(simAdapter);
