Just to add. If someone wants to implement a filled circle bubble, heres the code (name it bage_circle.xml):
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="ring"
android:useLevel="false"
android:thickness="9dp"
android:innerRadius="0dp"
>
<solid
android:color="#F00"
/>
<stroke
android:width="1dip"
android:color="#FFF" />
<padding
android:top="2dp"
android:bottom="2dp"/>
</shape>
You may have to adjust the thickness according to your need.
EDIT:
Here's the layout for button (name it badge_layout.xml):
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<com.joanzapata.iconify.widget.IconButton
android:layout_width="44dp"
android:layout_height="44dp"
android:textSize="24sp"
android:textColor="@color/white"
android:background="@drawable/action_bar_icon_bg"
android:id="@+id/badge_icon_button"/>
<TextView
android:id="@+id/badge_textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="@id/badge_icon_button"
android:layout_alignRight="@id/badge_icon_button"
android:layout_alignEnd="@id/badge_icon_button"
android:text="10"
android:paddingEnd="8dp"
android:paddingRight="8dp"
android:paddingLeft="8dp"
android:gravity="center"
android:textColor="#FFF"
android:textSize="11sp"
android:background="@drawable/badge_circle"/>
</RelativeLayout>
In Menu create item:
<item
android:id="@+id/menu_messages"
android:showAsAction="always"
android:actionLayout="@layout/badge_layout"/>
In onCreateOptionsMenu get reference to the Menu item:
itemMessages = menu.findItem(R.id.menu_messages);
badgeLayout = (RelativeLayout) itemMessages.getActionView();
itemMessagesBadgeTextView = (TextView) badgeLayout.findViewById(R.id.badge_textView);
itemMessagesBadgeTextView.setVisibility(View.GONE); // initially hidden
iconButtonMessages = (IconButton) badgeLayout.findViewById(R.id.badge_icon_button);
iconButtonMessages.setText("{fa-envelope}");
iconButtonMessages.setTextColor(getResources().getColor(R.color.action_bar_icon_color_disabled));
iconButtonMessages.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (HJSession.getSession().getSessionId() != null) {
Intent intent = new Intent(getThis(), HJActivityMessagesContexts.class);
startActivityForResult(intent, HJRequestCodes.kHJRequestCodeActivityMessages.ordinal());
} else {
showLoginActivity();
}
}
});
After receiving notification for messages, set the count:
itemMessagesBadgeTextView.setText("" + count);
itemMessagesBadgeTextView.setVisibility(View.VISIBLE);
iconButtonMessages.setTextColor(getResources().getColor(R.color.white));
This code uses Iconify-fontawesome.
