Android程序开发之ListView实现横向滚动(带表头与固定列)

问题背景：在做图表展示的时候，listview可以上下左右滑动，但最左边一列在向右滑动时，保持不变，表头在向下滑动时保持不变。

有用两个listview实现的，但测试过，好像有些问题

这个例子是通过（listview + horizontalscrollview）实现的

效果图：

 

activity代码

/** 
* 
* 带滑动表头与固定列的listview 
*/ 
public class hlistactivity extends activity{ 
private listview mlistview; 
//方便测试，直接写的public 
public horizontalscrollview mtouchview; 
//装入所有的hscrollview 
protected list<chscrollview> mhscrollviews =new arraylist<chscrollview>(); 
@override 
protected void oncreate(bundle savedinstancestate) { 
super.oncreate(savedinstancestate); 
setcontentview(r.layout.scroll); 
initviews(); 
} 
private void initviews() { 
list<map<string, string>> datas = new arraylist<map<string,string>>(); 
map<string, string> data = null; 
chscrollview headerscroll = (chscrollview) findviewbyid(r.id.item_scroll_title); 
//添加头滑动事件 
mhscrollviews.add(headerscroll); 
mlistview = (listview) findviewbyid(r.id.scroll_list); 
for(int i = 0; i < 100; i++) { 
data = new hashmap<string, string>(); 
data.put("title", "title_" + i); 
data.put("data_" + 1, "date_" + 1 + "_" +i ); 
data.put("data_" + 2, "date_" + 2 + "_" +i ); 
data.put("data_" + 3, "date_" + 3 + "_" +i ); 
data.put("data_" + 4, "date_" + 4 + "_" +i ); 
data.put("data_" + 5, "date_" + 5 + "_" +i ); 
data.put("data_" + 6, "date_" + 6 + "_" +i ); 
datas.add(data); 
} 
simpleadapter adapter = new scrolladapter(this, datas, r.layout.item 
, new string[] { "title", "data_1", "data_2", "data_3", "data_4", "data_5", "data_6", } 
, new int[] { r.id.item_title 
, r.id.item_data1 
, r.id.item_data2 
, r.id.item_data3 
, r.id.item_data4 
, r.id.item_data5 
, r.id.item_data6 }); 
mlistview.setadapter(adapter); 
} 
public void addhviews(final chscrollview hscrollview) { 
if(!mhscrollviews.isempty()) { 
int size = mhscrollviews.size(); 
chscrollview scrollview = mhscrollviews.get(size - 1); 
final int scrollx = scrollview.getscrollx(); 
//第一次满屏后，向下滑动，有一条数据在开始时未加入 
if(scrollx != 0) { 
mlistview.post(new runnable() { 
@override 
public void run() { 
//当listview刷新完成之后，把该条移动到最终位置 
hscrollview.scrollto(scrollx, 0); 
} 
}); 
} 
} 
mhscrollviews.add(hscrollview); 
} 
public void onscrollchanged(int l, int t, int oldl, int oldt){ 
for(chscrollview scrollview : mhscrollviews) { 
//防止重复滑动 
if(mtouchview != scrollview) 
scrollview.smoothscrollto(l, t); 
} 
} 
class scrolladapter extends simpleadapter { 
private list<? extends map<string, ?>> datas; 
private int res; 
private string[] from; 
private int[] to; 
private context context; 
public scrolladapter(context context, 
list<? extends map<string, ?>> data, int resource, 
string[] from, int[] to) { 
super(context, data, resource, from, to); 
this.context = context; 
this.datas = data; 
this.res = resource; 
this.from = from; 
this.to = to; 
} 
@override 
public view getview(int position, view convertview, viewgroup parent) { 
view v = convertview; 
if(v == null) { 
v = layoutinflater.from(context).inflate(res, null); 
//第一次初始化的时候装进来 
addhviews((chscrollview) v.findviewbyid(r.id.item_scroll)); 
view[] views = new view[to.length]; 
for(int i = 0; i < to.length; i++) { 
view tv = v.findviewbyid(to[i]);; 
tv.setonclicklistener(clicklistener); 
views[i] = tv; 
} 
v.settag(views); 
} 
view[] holders = (view[]) v.gettag(); 
int len = holders.length; 
for(int i = 0 ; i < len; i++) { 
((textview)holders[i]).settext(this.datas.get(position).get(from[i]).tostring()); 
} 
return v; 
} 
} 
//测试点击的事件 
protected view.onclicklistener clicklistener = new view.onclicklistener() { 
@override 
public void onclick(view v) { 
toast.maketext(hlistactivity.this, ((textview)v).gettext(), toast.length_short).show(); 
} 
}; 
} 

滑动view代码

/** 
* 滑动代码 
*/ 
public class chscrollview extends horizontalscrollview { 
hlistactivity activity; 
public chscrollview(context context, attributeset attrs, int defstyle) { 
super(context, attrs, defstyle); 
activity = (hlistactivity) context; 
} 
public chscrollview(context context, attributeset attrs) { 
super(context, attrs); 
activity = (hlistactivity) context; 
} 
public chscrollview(context context) { 
super(context); 
activity = (hlistactivity) context; 
} 
@override 
public boolean ontouchevent(motionevent ev) { 
//进行触摸赋值 
activity.mtouchview = this; 
return super.ontouchevent(ev); 
} 
@override 
protected void onscrollchanged(int l, int t, int oldl, int oldt) { 
//当当前的chscrollview被触摸时，滑动其它 
if(activity.mtouchview == this) { 
activity.onscrollchanged(l, t, oldl, oldt); 
}else{ 
super.onscrollchanged(l, t, oldl, oldt); 
} 
} 
}
