實現listview滑動刪除功能
http://www.devstore.cn/code/info/579.html

首先設置listView.setOnTouchListener(onTouchListener);

    
listView = (ListView) findViewById(R.id.listView);
listView.setOnItemClickListener(onItemClickListener);
listView.setOnTouchListener(onTouchListener);

然后實現onTouchListener

    
View.OnTouchListener onTouchListener = new View.OnTouchListener() {
		float x, y, ux, uy;
		@Override
		public boolean onTouch(View v, MotionEvent event) {
			// TODO Auto-generated method stub
			switch (event.getAction()) {
			case MotionEvent.ACTION_DOWN:
				x = event.getX();
				y = event.getY();
				break;
			case MotionEvent.ACTION_UP:
				ux = event.getX();
				uy = event.getY();
				index = ((ListView)v).pointToPosition((int) x, (int) y);//item的position
				int p2 = ((ListView)v).pointToPosition((int) ux, (int) uy);
				if (index == p2 && Math.abs(x - ux) > 20) {
					notifyDataSetChanged();
				}
				return false;
			}

			return false;
		}

	};

最后在Adapter中如下實現：

    
class ListViewAdapter extends BaseAdapter {



		public ListViewAdapter() {
		}

		@Override
		public int getCount() {
			// TODO Auto-generated method stub
			return orders.size();
		}

		@Override
		public Object getItem(int position) {
			// TODO Auto-generated method stub
			return orders.get(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
			ViewHodler hodler;
			if (convertView == null) {
				hodler = new ViewHodler();
				convertView = LayoutInflater.from(context).inflate(R.layout.simple_item_4_for_my_order, null);
				hodler.item_0 = (TextView) convertView.findViewById(R.id.item_0);
				hodler.item_1 = (TextView) convertView.findViewById(R.id.item_1);
				hodler.item_2 = (TextView) convertView.findViewById(R.id.item_2);
				hodler.item_3 = (Button) convertView.findViewById(R.id.item_3);
				hodler.item_4 = (TextView) convertView.findViewById(R.id.item_4);
				convertView.setTag(hodler);
			} else {
				hodler = (ViewHodler) convertView.getTag();
			}
			final Order instance = orders.get(position);

			hodler.item_0.setText(instance.getStoreName());
			hodler.item_1.setText("$"+instance.getPaidAmt()+" for "+instance.getMenuNum()+" items");
			hodler.item_2.setText(instance.getCreateTime());

			if(position==index){
				if(hodler.item_3.getVisibility()==View.VISIBLE){
					hodler.item_3.setVisibility(View.GONE);
					doAnimation(context, hodler.item_3, R.anim.push_right_out);
				}else{
					hodler.item_3.setVisibility(View.VISIBLE);
					doAnimation(context, hodler.item_3, R.anim.push_right_in);
				}
				
					hodler.item_3.setText("Delete");
					hodler.item_3.setOnClickListener(new View.OnClickListener(){
						@Override
						public void onClick(View v) {
							App.order=instance;
							startCommand(context, handler, App.COMMAND_DELETE_ORDER);
						}
					});
				
			}else{
				hodler.item_3.setVisibility(View.GONE);
			}

			
			return convertView;
		}

		class ViewHodler {
			TextView item_0;
			TextView item_1;
			TextView item_2;
			Button item_3;
			TextView item_4;
		}

	}
