这个库提供了一个简单方法来给 ActionBar-MenuItem 添加一个小徽章图标。
If you want to update the item itself you can do the required stuff in the onOptionsItemSelected method and call invalidateOptionsMenu() afterwards.
Include in your project
Using Maven
The ActionItemBadge Library is pushed to [Maven Central], so you just need to add the following dependency to yourbuild.gradle.
dependencies { compile('com.mikepenz:actionitembadge:2.5.5@aar') { transitive = true } }
If you want to use this library with the old ActionBar. Do the following.
dependencies { compile 'com.tundem.actionitembadge:library:1.2.0@aar' }
You use ActionbarSherlock? No problem there's now a SNAPSHOT release for ActionbarSherlock. Just do the following:
Add the SNAPSHOT repo to your repositories:
maven { url 'https://oss.sonatype.org/content/repositories/snapshots/' }
And the compile dependency
dependencies { compile 'com.tundem.actionitembadge:library-abs:1.2.0@aar' }
Usage
menu.xml
Create your menu.xml as you would do normally and add the app:actionLayout param. It is also a good idea to set showAsAction="always" (The badge can only be shown in the actionbar)
<menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" xmlns:app="http://schemas.android.com/apk/res-auto"> <item android:id="@+id/item_samplebadge" app:actionLayout="@layout/menu_badge" app:showAsAction="always" android:title="@string/sample_1"/> </menu>
Activity
Override the onCreateOptionsMenu method
@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), FontAwesome.Icon.faw_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; }
If you want to update the item itself you can do the required stuff in the onOptionsItemSelected method and call invalidateOptionsMenu() afterwards.
@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); }
