Android BGABadgeView：BGABadgeImageView以及BGABadgeRelativeLayout（4）



Android BGABadgeView：BGABadgeImageView以及BGABadgeRelativeLayout（4）

在附录文章5,6,7的基础上，写一个小例子说明BGABadgeImageView以及BGABadgeRelativeLayout。现在比如常见的新浪微博的账号头像下，如果有些大v账号，会额外显示一个vip徽标。这个可以用BGABadgeImageView实现，也可以是一个其他的普通BadgeView。

本例中的头像图是我的博客头像，vip图是新浪微博常见的vip小logo。

写一个布局：

<?xml version="1.0" encoding="utf-8"?>
<cn.bingoogolapple.badgeview.BGABadgeRelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:id="@+id/badgeRelativeLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="5dp"
    tools:context="zhangphil.demo.MainActivity">

    <cn.bingoogolapple.badgeview.BGABadgeImageView
        android:id="@+id/badgeImageView1"
        android:layout_width="wrap_content"

        android:layout_alignParentLeft="true"
        android:padding="5dp"
        android:src="@drawable/zhangphil"
        app:badge_horizontalMargin="5dp"
        app:badge_verticalMargin="5dp" />

    <cn.bingoogolapple.badgeview.BGABadgeImageView
        android:id="@+id/badgeImageView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"

        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:padding="5dp"
        android:src="@drawable/zhangphil" />
