ActionItemBadge:在actionbar上显示badge数字提示

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"

<itemandroid:id="@+id/item_samplebadge"android:actionLayout="@layout/menu_badge"android:showAsAction="always"android:title="@string/sample_1"/>

 

activity中

重写onCreateOptionsMenu

 

@Overridepublic 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:

@Overridepublic 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);}
