Android 自定义View：带小红点的View

BadgeView

add badgeview to any targetView in Android

Usage

Step1

Add dependencies in build.gradle.

    dependencies {
           compile 'com.itingchunyu.badgeview:badgeview:1.0.5'
    }

注释：v1.0.5版本引用名称作如下修改

IBadgeTextView===>BadgeTextView
IBadgeViewImpl ===> IBadgeView
IBadgeView ===> BadgeViewUtil
以上三个类内部实现不变

BadgeViewUtil工具类

XML attributes自定义属性（BadgeTextView、BaseBadgeView）可使用

<declare-styleable name="BadgeViewUtil">
        <attr name="badge_padding_top" format="dimension" />
        <attr name="badge_padding_right" format="dimension" />
        <attr name="badge_count" format="integer" />
        <attr name="badge_none_show" format="boolean" />
        <attr name="badge_color" format="color" />
    </declare-styleable>

Step2

使用样例

    //第一种方式:可依附任意view(无限制:初始定位右上角)
    TextView tv = (TextView) findViewById(R.id.tv);
    BadgeTextView mBadgeView=new BadgeTextView(this);
    mBadgeView.setTargetView(tv);//设置目标targetView(可任意:此处只做演示)
    mBadgeView2.setBadgeCount(92)//数量(0:表示小红点)
            .setmDefaultRightPadding(20)//右依附视图距离
            .setmDefaultTopPadding(20);//上依附视图距离

    //第二种方式:布局中直接引用(仅作为TextView是用)
    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:background="#55ff0000"
        android:gravity="center">

        <!-- 目标View -->
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:background="#999"
            android:drawableTop="@mipmap/ic_launcher"
            android:gravity="center"
            android:text="" />

        <!-- 小红点  -->
        <com.itingchunyu.badgeview.BaseBadgeView
            android:id="@+id/btv_null"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="right|top"
            android:layout_marginRight="15dp"
            android:layout_marginTop="5dp"
            android:gravity="center"
            app:badge_count="10"
            app:badge_none_show="true" />

    </FrameLayout>
