ViewPage+ListView效果

   使用ViewPage+ListView做出如下图的效果:



   设计思路如下：

   1. 一个总的fragment作为父，三个选项分别也是fragment， 父类布局：

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/common_title_bg"
        android:orientation="horizontal">

        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="4"
            android:layout_marginTop="10dp"
            android:layout_marginBottom="10dp"
            android:layout_marginLeft="15dp"
            android:layout_marginRight="15dp"
            android:orientation="horizontal"
            android:background="@drawable/bg_city_search_selector">

            <ImageView
                android:layout_width="wrap_content"
                android:layout_height="match_parent"
                android:layout_marginLeft="15dp"
                android:src="@drawable/common_search_icon" />

            <EditText
                android:id="@+id/main_hall_search_txt"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="4"
                android:textSize="15sp"
                android:maxLength="15"
                android:singleLine="true"
                style="@style/common_edit_hint_drawable_style"
                android:paddingTop="10dp"
                android:paddingBottom="10dp"
                android:inputType="textNoSuggestions"
                android:hint="输入开发商名称" />

            <ImageView
                android:id="@+id/main_hall_search_delete_img"
                android:layout_width="wrap_content"
                android:layout_height="match_parent"
                style="@style/right_icon_class"
                android:clickable="true"
                android:src="@drawable/input_right_delete_icon"/>
        </LinearLayout>

        <RelativeLayout
            android:id="@+id/main_hall_cancel_lyt"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:clickable="true"
            android:gravity="center">

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                style="@style/top_text_big"
                android:text="@string/common_cancel"/>
        </RelativeLayout>
    </LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="@dimen/main_hall_title_height"
        android:background="@color/xwhite"
        android:orientation="horizontal">

        <RelativeLayout
            android:id="@+id/main_hall_search_lyt_0"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:clickable="true"
            android:gravity="center">

            <TextView
                android:id="@+id/main_hall_txt_0"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                style="@style/main_hall_search_title"
                android:text="综合"/>

            <ImageView
                android:id="@+id/main_hall_img_0"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                style="@style/main_hall_select_style" />
        </RelativeLayout>

        <View
            android:layout_width="1dp"
            android:layout_height="match_parent"
            style="@style/middle_separate_horizontal_style_10"/>

        <RelativeLayout
            android:id="@+id/main_hall_search_lyt_1"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:clickable="true">

            <TextView
                android:id="@+id/main_hall_txt_1"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                style="@style/main_hall_search_title"
                android:text="好评"/>

            <ImageView
                android:id="@+id/main_hall_img_1"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:visibility="invisible"
                style="@style/main_hall_select_style" />
        </RelativeLayout>

        <View
            android:layout_width="1dp"
            android:layout_height="match_parent"
            style="@style/middle_separate_horizontal_style_10"/>

        <RelativeLayout
            android:id="@+id/main_hall_search_lyt_2"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:clickable="true">

            <TextView
                android:id="@+id/main_hall_txt_2"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                style="@style/main_hall_search_title"
                android:text="砍价次数"/>

            <ImageView
                android:id="@+id/main_hall_img_2"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:visibility="invisible"
                style="@style/main_hall_select_style" />
        </RelativeLayout>
    </LinearLayout>

    <View
        android:layout_width="match_parent"
        android:layout_height="1dp"
        style="@style/middle_separate"/>

    <android.support.v4.view.ViewPager
        android:id="@+id/main_hall_search_viewpage"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" />

    2. 父类里面自定义了adapter，继承了FragmentStatePagerAdapter

public class LocalFragmentAdapter<T> extends FragmentStatePagerAdapter {

    private List<T> list;

    private Activity activity;

    public LocalFragmentAdapter(Fragment fm, List<T> list, Activity activity) {
        super(fm.getFragmentManager());
        this.list = list;
        this.activity = activity;
    }

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

    @Override
    public Fragment getItem(int i) {
        return (Fragment)list.get(i);
    }

    //用于刷新数据使用， 获取的查询字段放入缓存变量里面
    public void setSearchAndPosition(int currentPageIndex, Editable searchWord) {
        //用于刷新数据
        Fragment fragment = getItem(currentPageIndex);
        if (!TextUtils.isEmpty(searchWord)) {
            User.myself.mainHallSearchWord = searchWord.toString();
        } else {
            User.myself.mainHallSearchWord = null;
        }
        fragment.onResume();
        super.notifyDataSetChanged();
    }
}

    3. 父类代码

        //页面滚动
        main_hall_search_viewpage.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
            @Override
            public void onPageScrolled(int i, float v, int i1) {
            }

            @Override
            public void onPageSelected(int position) {
                changeSelect(position);
                fragmentAdapter.setSearchAndPosition(currentPageIndex, main_hall_search_txt.getText());
            }

            @Override
            public void onPageScrollStateChanged(int i) {
            }
        });


        //搜索字段
        main_hall_search_txt.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
            }

            @Override
            public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
            }

            @Override
            public void afterTextChanged(Editable editable) {
                fragmentAdapter.setSearchAndPosition(currentPageIndex, editable);
            }
        });

    4. 用于展示的三个子fragment使用LISTVIEW就可以， 配合适配器或自己定义的适配器


    注意：如果在每一个item里面还嵌套的有listview的话， 如针对某一个ITEM的多条回复
这个时候ITEM的焦点会被listview获取，有可能出现点item无响应的情况，需要在根目录下加：

android:descendantFocusability="blocksDescendants"
