Android仿微信滑动弹出编辑、删除菜单效果、增加下拉刷新功能

如何为不同的list item呈现不同的菜单，本文实例就为大家介绍了android仿微信或qq滑动弹出编辑、删除菜单效果、增加下拉刷新等功能的实现，分享给大家供大家参考，具体内容如下

效果图：

1. 下载开源项目，并将其中的liberary导入到自己的项目中：

2. 使用swipemenulistview代替listview，在页面中布局：

<android.support.v4.widget.swiperefreshlayout 
 android:id="@+id/swiperefreshmusic" 
 android:layout_width="match_parent" 
 android:layout_height="wrap_content"> 
 
 <com.baoyz.swipemenulistview.swipemenulistview 
  android:id="@+id/listviewmusic" 
  android:layout_width="match_parent" 
  android:layout_height="match_parent" /> 
 
</android.support.v4.widget.swiperefreshlayout> 

 注： swiperefreshlayout主要是为了给该列表增加下拉刷新功能！

3. 为该listview创建适配器，与正常的实现并无二致：

public class musicadapter extends baseadapter { 
 
 private list<music> mdatas; 
 
 private context mcontext; 
 
 public musicadapter(list<music> mdatas, context mcontext) { 
  this.mdatas = mdatas; 
  this.mcontext = mcontext; 
 } 
 
 @override 
 public int getcount() { 
  return mdatas.size(); 
 } 
 
 @override 
 public music getitem(int position) { 
  return mdatas.get(position); 
 } 
 
 @override 
 public long getitemid(int position) { 
  return position; 
 } 
 
 @override 
 public view getview(int position, view convertview, viewgroup parent) { 
  if (convertview == null) { 
   convertview = view.inflate(mcontext, r.layout.list_item_music, null); 
   new viewholder(convertview); 
  } 
 
  viewholder holder = (viewholder) convertview.gettag(); 
 
  music music = mdatas.get(position); 
 
  holder.texttitle.settext(music.title); 
  holder.textdesc.settext(music.desc); 
 
  return convertview; 
 } 
 
 class viewholder { 
  textview texttitle; 
  textview textdesc; 
 
  public viewholder(view view) { 
   texttitle = (textview) view.findviewbyid(r.id.texttitle); 
   textdesc = (textview) view.findviewbyid(r.id.textdesc); 
   view.settag(this); 
  } 
 } 
} 

4. 为swipemenulistview实现adapter，并在之后，创建滑动菜单：

public class mainactivity extends appcompatactivity { 
 
 @viewinject(r.id.listviewmusic) 
 private swipemenulistview listviewmusic; 
 
 @viewinject(r.id.swiperefreshmusic) 
 private swiperefreshlayout swiperefreshmusic; 
 
 private list<music> musics; 
 
 private musicadapter musicadapter; 
 
 @override 
 protected void oncreate(bundle savedinstancestate) { 
  super.oncreate(savedinstancestate); 
  setcontentview(r.layout.activity_main); 
 
  x.view().inject(this); 
  musics = new arraylist<>(); 
 
  for (int i = 0; i < 4; i++) { 
 
   music music = new music(); 
   music.title = "上邪 : " + i; 
   music.desc = "我欲与君相知，长命无绝衰"; 
   musics.add(music); 
  } 
 
  musicadapter = new musicadapter(musics, this); 
  listviewmusic.setadapter(musicadapter); 
 
  swipemenucreator swipemenucreator = new swipemenucreator() { 
   @override 
   public void create(swipemenu menu) { 
    // create "edit" item 
    swipemenuitem edititem = new swipemenuitem( 
      getapplicationcontext()); 
    // set item background 
    edititem.setbackground(new colordrawable(color.rgb(0xc9, 0xc9, 
      0xce))); 
    // set item width 
    edititem.setwidth(dp2px(90)); 
    // set item title 
    edititem.settitle("编辑"); 
    // set item title fontsize 
    edititem.settitlesize(18); 
    // set item title font color 
    edititem.settitlecolor(color.white); 
    // add to menu 
    menu.addmenuitem(edititem); 
 
    // create "edit" item 
    swipemenuitem deleteitem = new swipemenuitem( 
      getapplicationcontext()); 
    // set item background 
    deleteitem.setbackground(new colordrawable(color.parsecolor("#ff0000"))); 
    // set item width 
    deleteitem.setwidth(dp2px(90)); 
    // set item title 
    deleteitem.settitle("删除"); 
    // set item title fontsize 
    deleteitem.settitlesize(18); 
    // set item title font color 
    deleteitem.settitlecolor(color.white); 
    // add to menu 
    menu.addmenuitem(deleteitem); 
   } 
  }; 
 
  listviewmusic.setmenucreator(swipemenucreator); 
 
  listviewmusic.setonmenuitemclicklistener(new swipemenulistview.onmenuitemclicklistener() { 
   @override 
   public boolean onmenuitemclick(int position, swipemenu menu, int index) { 
    switch (index) {// index即是操作menu添加的顺序 
     case 0: 
      toast.maketext(mainactivity.this, "编辑 : " + position, toast.length_short).show(); 
      break; 
     case 1: 
      toast.maketext(mainactivity.this, "删除 : " + position, toast.length_short).show(); 
      musics.remove(position); 
      musicadapter.notifydatasetchanged(); 
      break; 
    } 
 
    return false; 
   } 
  }); 
 
  swiperefreshmusic.setonrefreshlistener(new swiperefreshlayout.onrefreshlistener() { 
   @override 
   public void onrefresh() { 
 
    swiperefreshmusic.setrefreshing(true); 
    new handler().postdelayed(new runnable() { 
     @override 
     public void run() { 
 
      for (int i = 0; i < 4; i++) { 
 
       music music = new music(); 
       music.title = "无缘 : " + i; 
       music.desc = "风雨千山玉独行，天下倾心叹无缘"; 
       musics.add(music); 
      } 
      musicadapter.notifydatasetchanged(); 
 
      swiperefreshmusic.setrefreshing(false); 
     } 
    }, 2000); 
 
   } 
  }); 
 } 
 
 private int dp2px(int dp) { 
  return (int) typedvalue.applydimension(typedvalue.complex_unit_dip, dp, 
    getresources().getdisplaymetrics()); 
 } 
} 

注： 
  1. swipemenucreator是为了给该listitem创建菜单使用，需要实现该的接口中的create方法，在该方法中，可以*创建菜单项，比如删除、编辑，可以设置菜单的背景颜色，字体颜色大小等；
  2. 在创建swipemenucreator实例后，需为列表设置菜单：listviewmusic.setmenucreator(swipemenucreator);
  3. 通过设置swipemenulistview的setonmenuitemclicklistener方法，监听菜单的点击事件，通过onmenuitemclick(int position, swipemenu menu, int index)方法，对菜单事件进行处理；
  4. 通过设置swipemenulistview的setonrefreshlistener方法，为菜单添加下拉刷新功能！
