首先看效果，数字图片+阴影图片组成如下效果（推测搞一套类似的字体也可以实现），实际实现逻辑是将图片逐个添加进Layout中（使用Adapter实现View的复用）。

用到的资源图片示例如下：0和0的阴影是下图这样的（图片宽高：90*102）。

my_assets_zero.png

my_assets_zero_shadow.png

代码如下：

   <com.hzc.yyh.imagetext.AssetRelativeLayout
        android:id="@+id/shouyilv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="15dp" />

设置数据：

((AssetRelativeLayout)findViewById(R.id.shouyilv)).setContent("1,023,456,789.0%");

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:id="@+id/num_rl"
    android:layout_height="wrap_content" >
    <ImageView
        android:id="@+id/shadow_iv"
        android:scaleType="fitCenter"
        android:layout_height="56dp"
        android:layout_width="48dp"
        android:contentDescription="@null"
        android:background="@drawable/my_assets_comma" />
    <ImageView
        android:id="@+id/num_iv"
        android:scaleType="fitCenter"
        android:layout_height="56dp"
        android:layout_width="48dp"
        android:background="@drawable/my_assets_comma_shadow"
        android:contentDescription="@null" />
