一手遮天 AndroID - vIEw（d出类）: PopupMenu 样式示例如下:

/** * PopupMenu - d出式菜单 * * 本例会演示如何自定义 PopupMenu 的样式 * 需要通过 activity 的主题来指定 PopupMenu 的样式，参见 res/values/styles.xml 中的 Mytheme_MyPopupMenuStyle * * 注：如果觉得 PopupMenu 实现不了需求，就用 PopupWindow 吧 */package com.webabcd.androIDdemo.vIEw.flyout;import androIDx.appcompat.app.AppCompatActivity;import androID.os.Bundle;import androIDx.appcompat.Widget.PopupMenu;import androID.vIEw.MenuItem;import androID.vIEw.VIEw;import androID.Widget.button;import androID.Widget.Toast;import com.webabcd.androIDdemo.R;public class PopupMenuDemo2 extends AppCompatActivity {    private button mbutton1;    @OverrIDe    protected voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        // 指定 activity 的主题，用于修改 PopupMenu 的样式        settheme(R.style.Mytheme_MyPopupMenuStyle);        setContentVIEw(R.layout.activity_vIEw_flyout_popupmenudemo2);        mbutton1 = findVIEwByID(R.ID.button1);        sample();    }    private voID sample() {        mbutton1.setonClickListener(new VIEw.OnClickListener() {            @OverrIDe            public voID onClick(VIEw v) {                final PopupMenu popup = new PopupMenu(PopupMenuDemo2.this, mbutton1);                popup.getMenuInflater().inflate(R.menu.menu_vIEw_flyout_popupmenudemo2, popup.getMenu());                popup.setonMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {                    @OverrIDe                    public boolean onMenuItemClick(MenuItem item) {                        Toast.makeText(PopupMenuDemo2.this, String.format("ID:%d, Title:%s", item.getItemID(), item.getTitle()), Toast.LENGTH_SHORT).show();                        // 如果 item 数据来自 xml 的话，则可以通过此方式来判断用户点击的是哪个 item                        if (item.getItemID() == popup.getMenu().getItem(1).getItemID()) {                        }                        return true;                    }                });                popup.show();            }        });    }}
