菜单实现之PopupMenu

PopupMenu（弹出菜单）：点击view后在view下面弹出的菜单

实现方法：
1.创建popup_menu

        PopupMenu popupMenu = new PopupMenu(this, button);//button是popupMenu的宿主，也可以是其他任意view        popupMenu.getMenuInflater().inflate(R.menu.content_menu, popupMenu.getMenu());

2.弹出菜单

 public void clicked(View view) {     popupMenu.show();//需要在点击事件中弹出菜单}

3.监听popupMenu的点击事件

 popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {            @Override            public boolean onMenuItemClick(MenuItem item) {                return false;            }        });
