写ripple drawable时候，如果默认背景带透明度，则item加一个id="@android:id/mask"，以保证边界：
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
    android:color="?android:colorControlHighlight">

    <item android:id="@android:id/mask">
        <shape>
            <corners android:radius="4dp" />
            <solid android:color="@color/white" />
        </shape>
    </item>

UserCharge imoney为double类型:
cursor.getText() 和 cursor.getDouble()效果不能保证为一致！
getText()方法可能丢失精度，getDouble()方法结果正确


UserCharge imoney 为 text类型:
查询cursor.getText() 和 cursor.getDouble()效果一致！而且text类型并不影响sql对字段查询统计求和等操作

而且由于cursor代码是系统代码无法修改，ORM 将UserCharge的imoney字段改为String 或者 BigDecimal都只是按text读取，反而用double能保证读取结果正确
