Java非法參數異常android

我遇到這種錯誤，搜索可能的資源後仍然無法正常工作。Java非法參數異常android

錯誤：

java.lang.IllegalArgumentException: View android.widget.ExpandableListView{416b0bc8 VFED.VC. ......ID 0,0-480,0 #7f080005 app:id/lvExp} is not a drawer

繼承人我的代碼：

ExpandableListAdapter listAdapter; 
ExpandableListView expListView; 
List<String> listDataHeader; 
private DrawerLayout drawer; 
private LinearLayout linear; 
Button btn; 

HashMap<String, List<String>> listDataChild; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    prepareListData(); 

    btn = (Button)findViewById(R.id.button1); 
    linear = (LinearLayout)findViewById(R.id.linear); 
    expListView = (ExpandableListView) findViewById(R.id.lvExp); 
    drawer = (DrawerLayout)findViewById(R.id.drawer_layout); 

    btn.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View arg0) { 
      // TODO Auto-generated method stub 
     if(!drawer.isDrawerOpen(expListView)) 
     { 
      drawer.openDrawer(expListView); 
     } 
     else 
     { 
      drawer.closeDrawer(expListView); 
     } 

     } 
    }); 

    // get the listview 


    // preparing list data 


    listAdapter = new ExpandableListAdapter(this, listDataHeader, listDataChild); 

    // setting list adapter 
    expListView.setAdapter(listAdapter);

你可以發佈你的logcat嗎？由於聲譽有限， – PSK

無法發佈logcat，謝謝 – user3243065

你在if(!drawer.isDrawerOpen(expListView)) expListView名單越來越例外是不是一個抽屜。這就是爲什麼你越來越java.lang.IllegalArgumentException:

試試這個post你會得到一些想法。欲瞭解更多信息link
