本案例主要实现了ListView和ExpandableListView的侧滑删除操作功能
效果图：
ListView的Adapter类
private class SlideAdapter extends BaseAdapter {
private LayoutInflater mInflater;
SlideAdapter() {
super();
mInflater = getLayoutInflater();
}
@Override
public int getCount() {
return mMessageItems.size();
}
@Override
public Object getItem(int position) {
return mMessageItems.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
ZQView slideView = (ZQView) convertView;
if (slideView == null) {
View itemView = mInflater.inflate(R.layout.list_item, null);
slideView = new ZQView(ActivityListViewDelete.this);
slideView.setContentView(itemView);
holder = new ViewHolder(slideView);
slideView.setTag(holder);
} else {
holder = (ViewHolder) slideView.getTag();
}
MessageItem item = mMessageItems.get(position);
slideView.shrink();
holder.title.setText(item.title);
holder.time.setText(item.time);
holder.deleteHolder.setOnClickListener(ActivityListViewDelete.this);
return slideView;
}
}
public class MessageItem {
public String title;
public String msg;
public String time;
}
private static class ViewHolder {
public ImageView icon;
public TextView title;
public TextView time;
public ViewGroup deleteHolder;
ViewHolder(View view) {
icon = (ImageView) view.findViewById(R.id.icon);
title = (TextView) view.findViewById(R.id.title);
time = (TextView) view.findViewById(R.id.time);
deleteHolder = (ViewGroup) view.findViewById(R.id.holder);
}
}
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
Toast.makeText(this, "onItemClick position=" + position, Toast.LENGTH_LONG).show();
}
@Override
public void onClick(View v) {
if (v.getId() == R.id.holder) {
Toast.makeText(this, "删除操作", Toast.LENGTH_LONG).show();
}
}ExpandableListView的Adapter
private Context context;
private ListView listView;
List<UserInfo> list; public MyElvAdapter(Context context, ListView listView, List<UserInfo> list) {
super();
this.context = context;
this.listView = listView;
this.list=list;
} @Override
public Object getChild(int arg0, int arg1) {
// TODO Auto-generated method stub
return list.get(arg0).getDatas().get(arg1);
} @Override
public long getChildId(int arg0, int arg1) {
// TODO Auto-generated method stub
return 0;
} @Override
public View getChildView(final int groupPosition, final int position,
boolean arg2, View convertView, ViewGroup parent) { final ViewHolder1 viewHolder1;
if (convertView == null){
convertView = LayoutInflater.from(context).inflate(R.layout.item2,
null);
viewHolder1=new ViewHolder1(convertView);
convertView.setTag(viewHolder1); }else {
viewHolder1=(ViewHolder1)convertView.getTag();
}
new FrontViewToMove(viewHolder1.frontView, listView,200);
viewHolder1.button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
//删除事件，回调接口传参数
onClickDeleteListenter.onItemClick(v,groupPosition,position);
new FrontViewToMove(viewHolder1.frontView, listView,200).generateRevealAnimate(viewHolder1.frontView,0); }
});
viewHolder1.textView.setTextSize(20);
viewHolder1.textView.setTextColor(Color.DKGRAY);
viewHolder1.textView.setText(" " + list.get(groupPosition).getDatas().get(position).getName());
return convertView;
} class ViewHolder1 {
private TextView textView;
private View frontView;
private Button button;
public ViewHolder1(View view){
textView= (TextView) view.findViewById(R.id.text);
button = (Button) view.findViewById(R.id.btn_delete);
frontView = view.findViewById(R.id.id_front);
}
} // 删除接口回调方法
private OnClickDeleteListenter onClickDeleteListenter = null;
public void setOnClickDeleteListenter(OnClickDeleteListenter listener) {
this.onClickDeleteListenter = listener;
} @Override
public int getChildrenCount(int arg0) {
// TODO Auto-generated method stub
return (list!=null && list.size()>0)? list.get(arg0).getDatas().size() : 0;
} @Override
public Object getGroup(int arg0) {
// TODO Auto-generated method stub
return list.get(arg0);
} @Override
public int getGroupCount() {
// TODO Auto-generated method stub
return (list!=null && list.size()>0) ? list.size() : 0;
} @Override
public long getGroupId(int arg0) {
// TODO Auto-generated method stub
return 0;
} @Override
public View getGroupView(final int groupPosition, boolean isExpanded,
View convertView, ViewGroup parent) {
final ViewHolder viewHolder;
if (convertView ==null){
convertView = LayoutInflater.from(context).inflate(R.layout.item1,null);
viewHolder =new ViewHolder(convertView);
convertView.setTag(viewHolder);
}else {
viewHolder=(ViewHolder)convertView.getTag();
}
viewHolder.textView.setText("条目 " + list.get(groupPosition).getId());
viewHolder.textView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(context,"第一层点击操作",Toast.LENGTH_LONG).show();
}
});
return convertView;
} @Override
public boolean hasStableIds() {
// TODO Auto-generated method stub
return false;
} @Override
public boolean isChildSelectable(int arg0, int arg1) {
// TODO Auto-generated method stub
return false;
} class ViewHolder {
TextView textView;
public ViewHolder(View view){
textView= (TextView) view.findViewById(R.id.name);
}
}
注：更新修复侧滑删除报错。
