Android UI设计: 仿QQ好友列表分组悬停，自定义Header，下拉刷新结合Demo

浏览数：27 / 时间：2015年06月11日

之前学习了Pulltorefresh，pinnedheaderexpanablelistview 但是结合起来还是有点麻烦的。尤其是像QQ这种。他不是单纯的第一个当做分组。他是分组上面还有几个按钮，还有搜索框，同时可以滑动，而且还可以悬停。想了试了好几种方法，都有BUG。最后用的一种方法。
1. pulltorefresh用的android.v4里面自带的，好像知乎也是
2. 悬停和分组用的网上的，然后我把第一个分组的样式改成了自定义的menu菜单，并且清空了child.这样看上去就像一个自定义layout和listview一起滑动。
3. 下面是样式图

整个部分是可以滑动的。

下拉刷新之后最上面会有一个彩色带。有点细。这是系统弄的效果

这是悬停效果，之前的自定义菜单被滑动上去了。
下面是核心代码，非常简洁

package com.android.activity;

import android.app.Activity;

import com.android.pinnedheader.PinnedHeaderExpandableListView;

public class MainActivity extends Activity{
    private PinnedHeaderExpandableListView explistview;
    private SwipeRefreshLayout swipeRefreshLayout;
    private String[][] childrenData = new String[10][10];
    private String[] groupData = new String[5];
    private int expandFlag = -1;//控制列表的展开  
    private MainAdapter adapter;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.layout_main);
        initView();
        initData();
    }

    /**

     */
    private void initView() {
        explistview = (PinnedHeaderExpandableListView)findViewById(R.id.explistview);
        swipeRefreshLayout = (SwipeRefreshLayout)findViewById(R.id.swipe_container);
        //设置刷新时动画的颜色，可以设置4个
        swipeRefreshLayout.setColorSchemeResources(android.R.color.holo_blue_light, android.R.color.holo_red_light, android.R.color.holo_orange_light, android.R.color.holo_green_light);
        swipeRefreshLayout.setOnRefreshListener(new OnRefreshListener() {

                      @Override
                      public void onRefresh() {
                         new Handler().postDelayed(new Runnable() {

                             @Override
                             public void run() {
                                 swipeRefreshLayout.setRefreshing(false);
                             }
                         }, 6000);
                     }
                 });
    }

    /**
     * 初始化数据
     */
    private void initData() {
        for(int i=0;i<5;i++){
            groupData[i] = " group "+i;
        }
        for(int i=1;i<5;i++){
            for(int j=0;j<10;j++){
                childrenData[i][j] = "qq "+j;
            }
        }
        //设置悬浮头部VIEW
        explistview.setHeaderView(View.inflate(MainActivity.this,R.layout.group,
                null));
        adapter = new MainAdapter(childrenData, groupData, getApplicationContext(),explistview);
        explistview.setAdapter(adapter);
        explistview.setOnChildClickListener(new OnChildClickListener() {

            @Override
            public boolean onChildClick(ExpandableListView parent, View v,
                    int groupPosition, int childPosition, long id) {
                Toast.makeText(MainActivity.this, "分组:"+groupData[groupPosition]+",好友:"+childrenData[groupPosition][childPosition], Toast.LENGTH_SHORT).show();
                return false;
            }
        });
    }
}

你需要做的就是设置监听器和传数据，记住数据第一组不会显示的，而且child必须为0个。
菜单样式和分组样式在这里getview设置。
