Question

我有一个listview withcin活动，当有人点击时在listview中的项目上，我想要开始一个类型的活动 TabActivity。

关于它为什么不起作用的任何想法？

    list.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            JobListRowData item = jobListAdapter.getItem(position);
                Intent myIntent = new Intent(view.getContext(), EventsTabs.class);                  
                startActivity(myIntent);
            }  }    });


    public class EventsTabs extends TabActivity {
    private TabHost mTabHost;

    @Override 
    public void onCreate(Bundle savedInstanceState) {  
      setContentView(R.layout.event_main);
      Resources res = getResources(); 
      TabHost tabHost = getTabHost();  
      TabHost.TabSpec spec;  
      Intent intent;  
      intent = new Intent().setClass(this, EventsTabs.class);    
      spec = tabHost.newTabSpec("artists").setIndicator("Artists", res.getDrawable(R.drawable.icon)).setContent(intent);    
      tabHost.addTab(spec);    
      intent = new Intent().setClass(this, EventsTabs.class);    
      spec = tabHost.newTabSpec("albums").setIndicator("Albums",res.getDrawable(R.drawable.icon)).setContent(intent);
      tabHost.addTab(spec);    
      intent = new Intent().setClass(this, EventsTabs.class);    
      spec = tabHost.newTabSpec("songs").setIndicator("Songs", res.getDrawable(R.drawable.icon)).setContent(intent);
      tabHost.addTab(spec);    
      tabHost.setup(); 
     }  

    }

出于某种原因，我得到了： 12-06 13：37：47.607：ERROR / AndroidRuntime（346）：引起：java.lang.IllegalStateException：在创建包含组之前，无法添加活动。

尝试将此添加到您的代码中..

 LocalActivityManager mlam = new LocalActivityManager(this, false);

  mlam.dispatchCreate(savedInstanceState);
  tabHost.setup(mlam );

编辑：你应该在向它添加标签之前设置tabhost ..

您应该首先调用设置......

TabHost tabHost = getTabHost();  
  TabHost.TabSpec spec;  
   tabHost.setup(); //Move set up here

  Intent intent;  
  intent = new Intent().setClass(this, EventsTabs.class);    
  spec = tabHost.newTabSpec("artists").setIndicator("Artists", res.getDrawable(R.drawable.icon)).setContent(intent);    
  tabHost.addTab(spec);    
  intent = new Intent().setClass(this, EventsTabs.class);    
  spec = tabHost.newTabSpec("albums").setIndicator("Albums",res.getDrawable(R.drawable.icon)).setContent(intent);
  tabHost.addTab(spec);    
  intent = new Intent().setClass(this, EventsTabs.class);    
  spec = tabHost.newTabSpec("songs").setIndicator("Songs", res.getDrawable(R.drawable.icon)).setContent(intent);
  tabHost.addTab(spec);
