android pop up menu

使用方法

res/menu下面新建 popup_menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" 
      xmlns:tools="http://schemas.android.com/tools">  
<item
     android:id="@+id/special_topic"  
     android:title="专题"/>  
 
    <item  
        android:id="@+id/elite"  
        android:title="精选"/>  
 
</menu>

在activity或者fragment中使用PopupMenu

       final  ImageButton moreMenu = (ImageButton)v.findViewById(R.id.more_menu);
        moreMenu.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v){
                   PopupMenu popup = new PopupMenu(getActivity(), moreMenu);
                    //Inflating the Popup using xml file
                    popup.getMenuInflater()
                        .inflate(R.menu.poupup_menu_home, popup.getMenu());
 
                    //registering popup with OnMenuItemClickListener
                    popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                        public boolean onMenuItemClick(MenuItem item) {
                  
                            return true;
                        }
                    });
 
                    popup.show(); //showing popup menu 
            }
        });

其中MoreMenu是一个按钮，由他触发PopupMenu的显示。
