今天来实现以下大众点评客户端的横向listview二级列表，先看一下样式。
 
这种横向的listview二级列表在手机软件上还不太常见，但是使用过平板的都应该知道，在平板上市比较常见的。可能是因为平板屏幕比较大，而且也能展现更多的内容。
下面来看一下我的实现步骤。
首先自定义一个listview，代码如下：
代码如下:

public class MyListView extends ListView implements Runnable {
private float mLastDownY = 0f;
private int mDistance = 0;
private int mStep = 10;
private boolean mPositive = false;
public MyListView (Context context, AttributeSet attrs) {
super(context, attrs);
}
public MyListView (Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public MyListView (Context context) {
super(context);
}
@Override
public boolean onTouchEvent(MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
if (mLastDownY == 0f && mDistance == 0) {
mLastDownY = event.getY();
return true;
}
break;
case MotionEvent.ACTION_CANCEL:
break;
case MotionEvent.ACTION_UP:
if (mDistance != 0) {
mStep = 1;
mPositive = (mDistance >= 0);
this.post(this);
return true;
}
mLastDownY = 0f;
mDistance = 0;
break;
case MotionEvent.ACTION_MOVE:
if (mLastDownY != 0f) {
mDistance = (int) (mLastDownY - event.getY());
if ((mDistance < 0 && getFirstVisiblePosition() == 0 && getChildAt(0).getTop() == 0) || (mDistance > 0 && getLastVisiblePosition() == getCount() - 1)) {
mDistance /= 2;
scrollTo(0, mDistance);
return true;
}
}
mDistance = 0;
break;
}
return super.onTouchEvent(event);
}
public void run() {
mDistance += mDistance > 0 ? -mStep : mStep;
scrollTo(0, mDistance);
if ((mPositive && mDistance = 0)) {
scrollTo(0, 0);
mDistance = 0;
mLastDownY = 0f;
return;
}
mStep += 1;
this.postDelayed(this, 10);
}
}

然后看一下xml的布局：
代码如下:










两个自定义的listview 横向布局，然后是父listview的适配器
代码如下:

public class MyAdapter extends BaseAdapter {
Context context;
LayoutInflater inflater;
String [] foods;
int last_item;
int [] images;
private int selectedPosition = -1;
public MyAdapter(Context context,String [] foods,int[] images){
this.context = context;
this.foods = foods;
this.images = images;
inflater=LayoutInflater.from(context);
}

@Override
public int getCount() {
// TODO Auto-generated method stub
return foods.length;
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
ViewHolder holder = null;
if(convertView==null){
convertView = inflater.inflate(R.layout.mylist_item, null);
holder = new ViewHolder();
holder.textView =(TextView)convertView.findViewById(R.id.textview);
holder.imageView =(ImageView)convertView.findViewById(R.id.imageview);
holder.layout=(LinearLayout)convertView.findViewById(R.id.colorlayout);
convertView.setTag(holder);
}
else{
holder=(ViewHolder)convertView.getTag();
}
// 设置选中效果
if(selectedPosition == position)
{
holder.textView.setTextColor(Color.BLUE);

holder.layout.setBackgroundColor(Color.LTGRAY);
} else {
holder.textView.setTextColor(Color.WHITE);
holder.layout.setBackgroundColor(Color.TRANSPARENT);
}

holder.textView.setText(foods[position]);
holder.textView.setTextColor(Color.BLACK);
holder.imageView.setBackgroundResource(images[position]);

return convertView;
}
public static class ViewHolder{
public TextView textView;
public ImageView imageView;
public LinearLayout layout;
}
public void setSelectedPosition(int position) {
selectedPosition = position;
}
}

对应的 item布局：
代码如下:








然后是子适配器代码：
代码如下:

public class SubAdapter extends BaseAdapter {

Context context;
LayoutInflater layoutInflater;
String[][] cities;
public int foodpoition;
public SubAdapter(Context context, String[][] cities,int position) {
this.context = context;
this.cities = cities;
layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
this.foodpoition = position;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return cities.length;
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return getItem(position);
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
ViewHolder viewHolder = null;
final int location=position;
if (convertView == null) {
convertView = layoutInflater.inflate(R.layout.sublist_item, null);
viewHolder = new ViewHolder();
viewHolder.textView = (TextView) convertView
.findViewById(R.id.textview1);
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
viewHolder.textView.setText(cities[foodpoition][position]);
viewHolder.textView.setTextColor(Color.BLACK);

return convertView;
}
public static class ViewHolder {
public TextView textView;
}
}

对应的xml布局：
代码如下:






最后看下主activity的实现代码
代码如下:

public class MainActivity extends Activity {
private MyListView listView;
private MyListView subListView;
private MyAdapter myAdapter;
private SubAdapter subAdapter;

String cities[][] = new String[][] {
new String[] {"全部美食", "本帮江浙菜", "川菜", "粤菜", "湘菜","东北菜","台湾菜","新疆/清真","素菜","火锅","自助餐","小吃快餐","日本","韩国料理",
"东南亚菜","西餐","面包甜点","其他"},
new String[] {"全部休闲娱乐","咖啡厅","酒吧","茶馆","KTV","电影院","游乐游艺","公园","景点/郊游","洗浴","足浴按摩","文化艺术",
"DIY手工坊","桌球馆","桌面游戏","更多休闲娱乐"},
new String[] {"全部购物", "综合商场", "服饰鞋包", "运动户外","珠宝饰品","化妆品","数码家电","亲子购物","家居建材"
,"书店","书店","眼镜店","特色集市","更多购物场所","食品茶酒","超市/便利店","药店"},
new String[] {"全部休闲娱乐","咖啡厅","酒吧","茶馆","KTV","电影院","游乐游艺","公园","景点/郊游","洗浴","足浴按摩","文化艺术",
"DIY手工坊","桌球馆","桌面游戏","更多休闲娱乐"},
new String[] {"全","咖啡厅","酒吧","茶馆","KTV","游乐游艺","公园","景点/郊游","洗浴","足浴按摩","文化艺术",
"DIY手工坊","桌球馆","桌面游戏","更多休闲娱乐"},
new String[] {"全部","咖啡厅","酒吧","茶馆","电影院","游乐游艺","公园","景点/郊游","洗浴","足浴按摩","文化艺术",
"DIY手工坊","桌球馆","桌面游戏","更多休闲娱乐"},
new String[] {"全部休","咖啡厅","酒吧","茶馆","KTV","电影院","游乐游艺","公园","景点/郊游","洗浴","足浴按摩","文化艺术",

new String[] {"全部休闲","咖啡厅","酒吧","茶馆","KTV","电影院","游乐游艺","公园","景点/郊游","洗浴","足浴按摩","文化艺术",
"DIY手工坊","桌球馆","桌面游戏","更多休闲娱乐"},
new String[] {"全部休闲娱","咖啡厅","酒吧","茶馆","KTV","电影院","游乐游艺","公园","景点/郊游","洗浴","足浴按摩","文化艺术",
"DIY手工坊","桌球馆","桌面游戏"},
new String[] {"全部休闲娱乐","咖啡厅","酒吧","茶馆","KTV","电影院","游乐游艺","公园","景点/郊游","洗浴","足浴按摩","文化艺术",
"DIY手工坊","桌球馆","桌面游戏","更多休闲娱乐"},
new String[] {"全部休闲aaa","咖啡厅","酒吧","茶馆","KTV","电影院","游乐游艺","公园","景点/郊游","洗浴","足浴按摩","文化艺术",
"DIY手工坊","桌球馆","桌面游戏"},
};
String foods[] =new String []{"全部频道","美食","休闲娱乐","购物","酒店","丽人","运动健身","结婚","亲子","爱车","生活服务"};
int images[] = new int[]{R.drawable.ic_category_0,R.drawable.ic_category_10,R.drawable.ic_category_30,R.drawable.ic_category_20
,R.drawable.ic_category_60,R.drawable.ic_category_50,R.drawable.ic_category_45,R.drawable.ic_category_50,R.drawable.ic_category_70,
R.drawable.ic_category_65,R.drawable.ic_category_80};

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
init();
myAdapter=new MyAdapter(getApplicationContext(), foods, images);
listView.setAdapter(myAdapter);
selectDefult();
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView arg0, View arg1, int position,
long arg3) {
// TODO Auto-generated method stub
final int location=position;
myAdapter.setSelectedPosition(position);
myAdapter.notifyDataSetInvalidated();
subAdapter=new SubAdapter(getApplicationContext(), cities, position);
subListView.setAdapter(subAdapter);
subListView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView arg0, View arg1,
int position, long arg3) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), cities[location][position], Toast.LENGTH_SHORT).show();
}
});
}
});
}
private void init(){
listView=(MyListView) findViewById(R.id.listView);
subListView=(MyListView) findViewById(R.id.subListView);
}
private void selectDefult(){
final int location=0;
myAdapter.setSelectedPosition(0);
myAdapter.notifyDataSetInvalidated();
subAdapter=new SubAdapter(getApplicationContext(), cities, 0);
subListView.setAdapter(subAdapter);
subListView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView arg0, View arg1,
int position, long arg3) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), cities[location][position], Toast.LENGTH_SHORT).show();
}
});
}
}

默认我选中了第0个，下面看一下运行效果：
