ListView之侧滑删除

SwipeMenuListView 是一个为listview添加item侧滑菜单的开源库,项目地址:https://github.com/baoyongzhang/SwipeMenuListView

使用:

				list.remove(position);
				madapter.notifyDataSetChanged();
				break;
			}
				return <span style="color:#ff0000;">true</span>;//注意一定要返回true,表示处理了这次事件,不让事件传递下去
			}
		});
		mListView.setOnItemClickListener(new OnItemClickListener() {//设置ListView监听器

			@Override
			public void onItemClick(AdapterView<?> parent, View view,
					int position, long id) {
				Toast.makeText(getApplicationContext(), ""+position, 0).show();	
			}
		});
		mListView.setCloseInterpolator(new BounceInterpolator());//设置item的滑动动画
		mListView.setOpenInterpolator(new BounceInterpolator());
	
	}
	private int dp2px(int dp) {//dp转换为px
		return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dp,
				getResources().getDisplayMetrics());
	}
}
按照以上步骤,滑动删除的ListView就可以完美实现了。

假如你要实现滑动不同的item有不同的侧滑menu显示,可以这样实现:

1、在create()方法中,加个switch选择语句

SwipeMenuCreator creator = new SwipeMenuCreator() {
			@Override
			public void create(SwipeMenu menu) {
				// Create different menus depending on the view type
				switch (menu.getViewType()) {
				case 0:
					createMenu1(menu);
					break;
				case 1:
					createMenu2(menu);
					break;
				case 2:
					createMenu3(menu);
					break;
				}
			}

2、适配器继承BaseAdapter,实现其中两个方法:

class madapter extends BaseAdapter{
			@Override
			public int getViewTypeCount() {//设置item有几种类型
				return 2;
			}
			@Override
			public int getItemViewType(int position) {//定义item的类型
				return position%2;
			}

顺便补充一下android之interpolator的用法:

android:interpolator

 

   Interpolator 被用来修饰动画效果,定义动画的变化率,可以使存在的动画效果accelerated(加速),decelerated(减速),repeated(重复),bounced(弹跳)等。

  android中的文档内容如下:

ListView之侧滑删除_第1张图片

 AccelerateDecelerateInterpolator 在动画开始与结束的地方速率改变比较慢,在中间的时候加速

     AccelerateInterpolator  在动画开始的地方速率改变比较慢,然后开始加速

   AnticipateInterpolator 开始的时候向后然后向前甩

   AnticipateOvershootInterpolator 开始的时候向后然后向前甩一定值后返回最后的值

   BounceInterpolator   动画结束的时候弹起

   CycleInterpolator 动画循环播放特定的次数,速率改变沿着正弦曲线

   DecelerateInterpolator 在动画开始的地方快然后慢

     LinearInterpolator   以常量速率改变

     OvershootInterpolator    向前甩一定值后再回到原来位置


使用起来很简单,直接new对象使用,mListView.setCloseInterpolator(new BounceInterpolator());//设置item的滑动动画
