第一阶段第五天冲刺

五一假期通过学习popupmenu实现了类似空间的弹出式选项菜单

private void showPopupMenu(View view,int position) {
    //view为当前menu显示相对于button的位置
    PopupMenu popupMenu = new PopupMenu(getContext(),view);
    popupMenu.getMenuInflater().inflate(R.menu.item,popupMenu.getMenu());
    popupMenu.show();
    popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
        @Override
        public boolean onMenuItemClick(MenuItem item) {
            switch(item.getItemId()){
                case R.id.add:
                    Toast.makeText(getContext(), "我点击了第"+position+"个item的添加", Toast.LENGTH_SHORT).show();
                    break;
            }
            return false;
        }
    });
    popupMenu.setOnDismissListener(new PopupMenu.OnDismissListener() {
        @Override
        public void onDismiss(PopupMenu menu) {

        }
    });
