ActionItemBadge：在actionbar上显示badge数字提示

RichardUmf 9年前

介绍：

一个方便你让你在actionbar上显示数字提示的库（这种效果称为badge ）。其实现原理是利用了menu菜单资源文件属性actionLayout

运行效果：

使用说明：

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"。

</tr> </tbody> </table> </div> </div>

activity中

重写onCreateOptionsMenu

1
2
3
4
5
</td>
<item
android:id= "@+id/item_samplebadge"
android:actionLayout= "@layout/menu_badge"
android:showAsAction= "always"
android:title= "@string/sample_1" />
</tr> </tbody> </table> </div> </div>

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：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
</td>
@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 ;
}
</tr> </tbody> </table> </div> </div>
