仿抽屉式的ListView-StickyListHeadersListView的使用

来源：互联网发布：牛人的工作效率知乎编辑：程序博客网时间：2024/06/01 11:23

1.首先 gradel

compile 'se.emilsjolander:stickylistheaders:x.x.x'

用最新版本号代替x.x.x ,我这里使用的是 2.1.1

2.Adapter

public class MyAdapter extends BaseAdapter implements StickyListHeadersAdapter {    private String[] countries={"上海","上海","上海","上海","上海","上海","上海","上海","北京","北京","北京","北京","北京","北京","北京","深圳","深圳","深圳","深圳","广州","广州","广州","广州","合肥","大连","耒阳","耒阳","耒阳","耒阳","长沙","湖南","湖南","湖南","湖南","益阳","张家界","欣欣","刘德华","张学友"};    private LayoutInflater inflater;    public MyAdapter(Context context) {        inflater = LayoutInflater.from(context);    }    @Override    public int getCount() {        return countries.length;    }    @Override    public Object getItem(int position) {        return countries[position];    }    @Override    public long getItemId(int position) {        return position;    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {        ViewHolder holder;        if (convertView == null) {            holder = new ViewHolder();            convertView = inflater.inflate(R.layout.test_list_item_layout, parent, false);            holder.text = (TextView) convertView.findViewById(R.id.text);            convertView.setTag(holder);        } else {            holder = (ViewHolder) convertView.getTag();        }        holder.text.setText(countries[position]);        return convertView;    }    @Override    public View getHeaderView(int position, View convertView, ViewGroup parent) {        HeaderViewHolder holder;        if (convertView == null) {            holder = new HeaderViewHolder();            convertView = inflater.inflate(R.layout.header, parent, false);            holder.text = (TextView) convertView.findViewById(R.id.text1);            convertView.setTag(holder);        } else {            holder = (HeaderViewHolder) convertView.getTag();        }        //set header text as first char in name        String headerText = "" + countries[position].subSequence(0, 1).charAt(0);        holder.text.setText(headerText);        return convertView;    }    @Override    public long getHeaderId(int position) {        //return the first character of the country as ID because this is what headers are based upon        return countries[position].subSequence(0, 1).charAt(0);    }    class HeaderViewHolder {        TextView text;    }    class ViewHolder {        TextView text;    }

3.xml

header.xml<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:background="@drawable/header_selector" >    <TextView        android:id="@+id/text1"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_gravity="start|left"        android:padding="5dp"        android:textColor="@android:color/white"        android:textSize="17sp"        android:textStyle="bold" /></RelativeLayout>
test_list_item_layout.xml

<TextView xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@+id/text"    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:layout_gravity="center_vertical"    android:paddingBottom="20dp"    android:paddingTop="20dp"/>
3.在activity中调用
 StickyListHeadersListView stickyList = (StickyListHeadersListView) findViewById(R.id.list);        MyAdapter adapter = new MyAdapter(this);        stickyList.setAdapter(adapter);
