三級級聯關係的列表，上面是我專案做出來的效果圖，這個是單選的效果。

實現的思路：左邊這個是listView ,右邊是兩級的expandListView 

將這兩個view 動態放到viewpager裡面 設定好比例，剩下的就是處理點選聯動事件了。

大體程式碼如下：

activity中 放viewpager的xml

   <LinearLayout
                android:id="@+id/category_ll"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_above="@+id/button_ll"
                android:layout_below="@+id/title_ll"
                android:orientation="vertical"
                android:visibility="gone">


                <com.jky.mobile_gczjjc.widget.MyViewPager
                    android:id="@+id/category_viewpager"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:overScrollMode="never" />

            </LinearLayout>
 

target_first_parger.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/target_divider_color"
    android:orientation="vertical">

    <ListView
        android:id="@+id/target_first_lv"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:background="@color/white"
        android:cacheColorHint="@android:color/transparent"
        android:divider="@null"
        android:scrollbars="none" />

target_second_parger.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/target_divider_color"
    android:orientation="vertical">

    <ExpandableListView
        android:id="@+id/target_second_exl"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:background="@color/white"
        android:cacheColorHint="@android:color/transparent"
        android:divider="@null"
        android:groupIndicator="@null"
        android:scrollbars="none" />
</LinearLayout>
 

activity中 核心程式碼

   //一級
        mViewPager = findViewById(R.id.category_viewpager);
        LayoutInflater inflater = LayoutInflater.from(this);
        view1 = inflater.inflate(R.layout.target_first_parger, null);
        view2 = inflater.inflate(R.layout.target_second_parger, null);
        mFirstListView = view1.findViewById(R.id.target_first_lv);
        mSecondListView = view2.findViewById(R.id.target_second_exl);

        mFirstAdapter = new TargetCategoryFirstAdapter(this, firstBeans);
        mFirstAdapter.setSelectedBackgroundResource(R.drawable.select_white);//選中時
        mFirstAdapter.setHasDivider(false);
        mFirstAdapter.setNormalBackgroundResource(R.color.target_bg_gray);//未選中
        mFirstListView.setAdapter(mFirstAdapter);

        views.add(view1);
        views.add(view2);//載入了一二級選單
        mViewPager.setAdapter(new MyPagerAdapter(views));
