                break;
        }

        invalidate();
    }


}

02)array.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <array name="recoder_time_start">
        <item>@drawable/recoder_number_play_0</item>
        <item>@drawable/recoder_number_play_0</item>
        <item>@drawable/recoder_number_play_0</item>
        <item>@drawable/recoder_number_play_0</item>
        <item>@drawable/recoder_number_play_0</item>
        <item>@drawable/recoder_number_play_0</item>
        <item>@drawable/recoder_number_play_0</item>
        <item>@drawable/recoder_number_play_0</item>
        <item>@drawable/recoder_number_play_0</item>
        <item>@drawable/recoder_number_play_0</item>
        <item>@drawable/recoder_number_play_0</item>
    </array>

</resources>

03)自定义style,提供接口,供使用者修改,res/values/attr.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <declare-styleable name="DigitalClock">
        <attr name="time_start_res" format="reference" />
        <attr name="time_pause_res" format="reference" />
        <attr name="time_stop_res" format="reference" />
        <attr name="children_gap" format="dimension" />
        <attr name="text_color" format="color" />
        <attr name="date_format" format="reference" />
        <attr name="date_height" format="dimension" />
        <attr name="date_margin_top" format="dimension" />
        <attr name="date_width" format="dimension" />
        <attr name="ampm_height" format="dimension" />
        <attr name="ampm_width" format="dimension" />
        <attr name="showdivider" format="reference"/>
        <attr name="ampm_gravity">
            <flag name="top" value="0x01" />
            <flag name="bottom" value="0x02" />
            <flag name="left" value="0x04" />
            <flag name="right" value="0x08" />
        </attr>
    </declare-styleable>


</resources>

04)如,在布局中使用该组件时:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:mandroid="http://schemas.android.com/apk/res-auto" 
.../>
<!--声明 mandroid ,供下面使用, 类似于android-->
<com.example.mworld.mView 
     android:id="@+id/digital_clock"
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:layout_centerHorizontal="true"
     android:layout_marginTop="@dimen/digital_marginTop"
     mandroid:children_gap ="@dimen/digital_gap"
     mandroid:time_start_res="@array/recoder_time_start"
     />

悦读

道可道，非常道；名可名，非常名。 无名，天地之始，有名，万物之母。 故常无欲，以观其妙，常有欲，以观其徼。 此两者，同出而异名，同谓之玄，玄之又玄，众妙之门。
