自定义XlistView(上拉加载，下拉刷新)控件

之前在博客里边讲了Android Studio自带的 下拉刷新控件，今天就把之前写过的自定义XlistView整理了一下，然后把代码贴出来。

首先肯定是先定义一个xml文件，代码如下:

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

    <com.example.administrator.xlistview.PullToRefreshView  android:id="@+id/main_pull_refresh_view_two" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" >
        <ListView  android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/listview_test" >
        </ListView>
    </com.example.administrator.xlistview.PullToRefreshView>

</LinearLayout>

接着就是在你的主界面里边进行整合，代码如下:

package com.example.administrator.stock_sell_storage_app;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ListView;
import com.example.administrator.dapter.DetailAdapter;
import com.example.administrator.xlistview.PullToRefreshView;
import com.lidroid.xutils.ViewUtils;
import com.lidroid.xutils.view.annotation.ViewInject;

public class DetailFragment extends Fragment implements PullToRefreshView.OnHeaderRefreshListener, PullToRefreshView.OnFooterRefreshListener {

    private View view;
    @ViewInject(R.id.listview_test)ListView listview_test;
    @ViewInject(R.id.main_pull_refresh_view_two)PullToRefreshView main_pull_refresh_view_two;
    DetailAdapter detailAdapter;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        view = inflater.inflate(R.layout.detai_fragment, container, false);
        ViewUtils.inject(this,view); //注入view和事件
        Instantiation();
        return view;

    }

    public void Instantiation(){

        main_pull_refresh_view_two.setOnHeaderRefreshListener(this);
        main_pull_refresh_view_two.setOnFooterRefreshListener(this);
        detailAdapter = new DetailAdapter(getActivity());
        listview_test.setAdapter(detailAdapter);


    }

    //上拉加载
    @Override
    public void onFooterRefresh(PullToRefreshView view) {
        main_pull_refresh_view_two.postDelayed(new Runnable() {
            //线程
            @Override
            public void run() {
                main_pull_refresh_view_two.onFooterRefreshComplete();
                //需要刷新的内容可以写在这里，比如网络请求
            }
        },1000);

    }

    //下拉刷新
    @Override
    public void onHeaderRefresh(PullToRefreshView view) {
        main_pull_refresh_view_two.postDelayed(new Runnable() {
            //线程
            @Override
            public void run() {
                main_pull_refresh_view_two.onHeaderRefreshComplete();
                //需要刷新的内容可以写在这里，比如网络请求
            }
        },1000);
    }

}

大家应该发现了在布局文件中的那个自定义控件，其实就是下边的这个东东……

OK!大家可以根据步骤把这几个类放在一个文件目录下。接下来还有一些相关的xml文件，我也一并贴在下边了。

xml(一) refresh_footer

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/pull_to_refresh_header" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@android:color/white" android:gravity="center" android:paddingBottom="10dip" android:paddingTop="10dip" >

xml(二) refresh_header

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/pull_to_refresh_header" android:background="@android:color/white" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center" android:paddingBottom="15dip" android:paddingTop="10dip" >

</RelativeLayout>

xml(三) xlistview_footer

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" >

    <RelativeLayout  android:id="@+id/xlistview_footer_content" android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="10dp" >

    </RelativeLayout>

</LinearLayout>

xml(四) xlistview_header

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="bottom" >

    <RelativeLayout  android:id="@+id/xlistview_header_content" android:layout_width="fill_parent" android:layout_height="60dp" >

        <LinearLayout  android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:gravity="center" android:orientation="vertical" android:id="@+id/xlistview_header_text">

            <TextView  android:id="@+id/xlistview_header_hint_textview" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/xlistview_header_hint_normal" />

            <LinearLayout  android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="3dp" >

                <TextView  android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/xlistview_header_last_time" android:textSize="12sp" />

                <TextView  android:id="@+id/xlistview_header_time" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="12sp" />
            </LinearLayout>
        </LinearLayout>

        <ImageView  android:id="@+id/xlistview_header_arrow" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignLeft="@id/xlistview_header_text" android:layout_centerVertical="true" android:layout_marginLeft="-35dp" android:src="@mipmap/xlistview_arrow" />

        <ProgressBar  android:id="@+id/xlistview_header_progressbar" android:layout_width="30dp" android:layout_height="30dp" android:layout_alignLeft="@id/xlistview_header_text" android:layout_centerVertical="true" android:layout_marginLeft="-40dp" android:visibility="invisible" />
    </RelativeLayout>

</LinearLayout>

好的，到了这里的话，基本上xml文件都来了，最后，再把一些资源文件也贴出来，包括里边用到的一些图片

    <!--XlistView-->
    <string name="pull_to_refresh_refreshing_label">刷新\u2026</string>
    <string name="pull_to_refresh_footer_release_label">松开后加载</string>
    <string name="pull_to_refresh_footer_refreshing_label">加载中\u2026</string>
    <string name="pull_to_refresh_release_label">松开后刷新</string>
    <string name="pull_to_refresh_footer_pull_label">上拉加载更多</string>
    <string name="pull_to_refresh_pull_label">下拉刷新</string>
    <string name="xlistview_header_hint_normal">下拉刷新</string>
    <string name="xlistview_header_hint_ready">松开刷新数据</string>
    <string name="xlistview_header_hint_loading">正在加载...</string>
    <string name="xlistview_header_last_time">上次更新时间：</string>
    <string name="xlistview_footer_hint_normal">查看更多</string>
    <string name="xlistview_footer_hint_ready">松开载入更多</string>

图片以及一些资源文件都贴上去了，到此处为止一个自定义的XlistView控件就实现了。把效果贴出来给他家看看，虽然是有点丑（- -）。

还是觉得有点丑…… 不过都是自定义的，大家可以按照自己的喜好来设计。
