按照正常方式创建一个menu.xml ，同事需要添加actionLayout，为了总是让这个菜单项显示出来，添加上showAsAction="always"。
<item android:id="@+id/item_samplebadge" android:actionLayout="@layout/menu_badge" android:showAsAction="always" android:title="@string/sample_1"/>
activity中
重写onCreateOptionsMenu
@Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); //you can add some logic (hide it if the count == 0) if(badgeCount > 0) { ActionItemBadge.update(this, menu.findItem(R.id.item_samplebadge), Iconify.IconValue.fa_android, ActionItemBadge.BadgeStyle.DARKGREY, badgeCount); } else{ ActionItemBadge.hide(menu.findItem(R.id.item_samplebadge)); } //If you want to add your ActionItem programmatically you can do this too. You do the following: new ActionItemBadge.Add().act(this).menu(menu).title(R.string.sample_2).itemDetails(0, SAMPLE2_ID, 1).showAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS).build(ActionItemBadge.BadgeStyle.BLUE_LARGE, 1); return true; }
如果你想在用户点击菜单项之后重新更新badge显示的数目，那么在onOptionsItemSelected中调用invalidateOptionsMenu方法：
@Override public boolean onOptionsItemSelected(MenuItem item) { int id = item.getItemId(); if(id == R.id.item_samplebadge) { Toast.makeText(this, R.string.sample_3, Toast.LENGTH_SHORT).show(); badgeCount--; invalidateOptionsMenu(); return true; } else if(id == SAMPLE2_ID) { Toast.makeText(this, R.string.sample_4, Toast.LENGTH_SHORT).show(); } return super.onOptionsItemSelected(item); }
