在 drawable 中绘制工具提示

Question

我想在我的按钮上添加工具提示。有什么简单的方法可以做到这一点。我想画形状。但我只找到带有绘图视图的方法或建议添加库。是否可以绘制工具提示（使用 xml 制作工具提示）？

将宽度和高度插入 size 标签，以便在较低的 API 级别中使用：

<item android:gravity="bottom|center_horizontal">

    <rotate android:fromDegrees="45" android:toDegrees="45"
        android:pivotX="50%" android:pivotY="50%" >

        <shape android:shape="rectangle">

            <size android:width="12dp" android:height="12dp" />

            <corners android:bottomRightRadius="2dp"/>

            <gradient android:type="linear"
                android:angle="0"
                android:endColor="@color/gradient_red"
                android:startColor="@color/gradient_red" />

        </shape>

    </rotate>

</item>

<item android:bottom="6dp">

    <shape android:shape="rectangle">

        <size android:width="120dp" android:height="36dp" />

        <gradient android:type="linear"
            android:angle="0"
            android:endColor="@color/gradient_red"
            android:startColor="@color/gradient_red" />

        <corners android:radius="6dp" />

    </shape>

</item>

<item
    android:top="17dp">

    <shape
        android:shape="rectangle">

        <solid
            android:color="#FF7276" />

        <corners
            android:radius="8dp" />

        <padding
            android:top="17dp" />

    </shape>

</item>

<item
    android:width="24dp"
    android:height="24dp"
    android:end="32dp"
    android:gravity="end"
    android:top="-12dp">

    <rotate
        android:fromDegrees="45">

        <shape
            android:shape="rectangle">

            <solid
                android:color="#FF7276" />

        </shape>

    </rotate>
