Android的ExpandableListActivity和TabActivity在同一级别 [英] Android ExpandableListActivity and TabActivity in same Class

问题描述

我试图用ExpandableListActivity在我的计划，但我已经继承了班上TabActivity。我不能做多重继承，我需要在我的程序同时使用ExpandableListView和标签。
我检查了谷歌的code为ExpandableListView这里的http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/ExpandableList1.html.

I am trying to use the ExpandableListActivity in my program but I have already inherited the TabActivity in my class. I cannot do multiple inheritance and I need to use both the ExpandableListView and the Tabs in my program. I checked Google's code for the ExpandableListView here http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/ExpandableList1.html.

但在这里他们继承它，因为我已经继承了TabActivity在我的课，我不能做ExpandableListActivity。

But here they are inheriting the ExpandableListActivity which I cannot do as I have already inherited TabActivity in my class.

我知道我可以使用的ListView没有在我的类继承ListActivity。我可以做的ExpandableListView类也一样吗？如果是这样，那么任何人都可以请我提供任何样品code使用ExtendableListView没有继承的活动？

I am aware that I can use ListView without inheriting ListActivity in my class. Can I do the same for the ExpandableListView class also ? If so, then can anyone please provide me with any sample code to use ExtendableListView without inheriting the activity ?

推荐答案

您可以扩展ExpandableListView自定义视图，并使用它里面TabActivity。

You can have a custom view that extends ExpandableListView and use it inside the TabActivity.

可扩展列表视图

  public class CustomExpListView extends ExpandableListView{
          /** Your code **/
     }

托管选项卡主要活动

Main Activity that hosts the tabs

public class MyTabActivity extends TabActivity{
    private TabHost tabhost;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          tabHost = getTabHost();
          tabHost.addTab(tabHost
                .newTabSpec("Tab 1")
                .setIndicator("Tab 1",
                        this.getResources().getDrawable(
                                R.drawable.tab_icon))
                .setContent(new Intent(this, Tab1.class)));

      /** Further code**/
    }
  }

有关与EXP列表的标签XML布局文件（制表1）

XML Layout file for the tab with the exp list (Tab 1)

/**Other layout stuff goes here**/
<com.jmango.nexus.view.ProductListView
        android:layout_width="fill_parent"
                    android:layout_height="wrap_content" 
                    android:groupIndicator="@drawable/group_indicator"
        android:childIndicator="@drawable/child_indicator"
        android:cacheColorHint="#00000000" 
                    android:divider="#00BBFF"
                    android:childDivider="@android:drawable/divider_horizontal_dark"
        android:smoothScrollbar="true"
        android:id="@+id/exp_list_view"/>

在类的EXP列表标签

CustomExpListView custExpListView = (CustomExpListView) this
            .findViewById(R.id.exp_list_view);

您还可以延长监听器和自定义。

You can also extend the listeners and customize it.
