Android顶部三个TabLayout,滑动到某条目，就会切换到相应的TabLayout

先上效果图 凑合看：

xml布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">
    <android.support.design.widget.TabLayout
        android:id="@+id/tb"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <android.support.design.widget.TabItem
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"

            android:text="baby" />

        <android.support.design.widget.TabItem
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"

            android:layout_height="wrap_content"
            android:text="detail" />
    </android.support.design.widget.TabLayout>
    <ListView

        android:layout_height="match_parent"
        android:id="@+id/lv"
        />
</LinearLayout>

MainActivity中：

        }
        initView();

    }

适配器：

public class CustomAdapter extends BaseAdapter {
    private ArrayList<String> list = new ArrayList<>();
    private Context context;

    public CustomAdapter(ArrayList<String> list, Context context) {
        this.list = list;
        this.context = context;
    }

    @Override
    public int getCount() {
        return list.size();
    }

    @Override
    public Object getItem(int position) {
        return list.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder viewHolder = null;
        if (convertView == null) {
            convertView = LayoutInflater.from(context).inflate(R.layout.item, null);
            viewHolder = new ViewHolder(convertView);
            convertView.setTag(viewHolder);
        }else {
            viewHolder = (ViewHolder)convertView.getTag();
        }
        viewHolder.tv.setText(list.get(position));
        return convertView;
    }

    public static class ViewHolder {
        public View rootView;
        public TextView tv;

        public ViewHolder(View rootView) {
            this.rootView = rootView;
            this.tv = (TextView) rootView.findViewById(R.id.tv);
        }
    }
}
