Question

好吧，我似乎在无处不在进行了搜索和搜索，但找不到答案。我认为这是因为我试图一次做太多事情。我想多次使用带有位图的矩形背景图像，并使用来自TextView的不同文本。

这是我一直尝试使用的位图（.png）文件的示例：

我想要一个TextView，其背景为可绘制的XML文件，该文件是一个图层列表。查看代码：

box_ones xml：

    <?xml version="1.0" encoding="utf-8"?>
    <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:width="128dp" android:height="34dp">
            <shape android:shape="rectangle">
                <stroke android:width="1dp"/>
                <solid android:color="@color/ivory"/>
                <corners android:topLeftRadius="16dp" android:topRightRadius="16dp"/>
            </shape>
        </item>
        <item android:right="10dp">
            <bitmap android:src="@drawable/dice_one" android:gravity="right|center_vertical"/>
        </item>
    </layer-list>

box_twos xml

    <?xml version="1.0" encoding="utf-8"?>
    <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:width="@string/tBoxWidth" android:height="@string/boxHeight">
            <shape android:shape="rectangle">
                <stroke android:width="1dp"/>
                <solid android:color="@color/ivory"/>
            </shape>
        </item>

<item android:right="10dp">
    <bitmap android:src="@drawable/dice_two" android:gravity="right|center_vertical"/>
</item>

activity_main xml：

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Ones"
        android:background="@drawable/box_ones"
        android:textAlignment="gravity"
        android:gravity="center_vertical"
        android:textSize="16sp"
        />

字符串xml

<resources>
    <string name="xSize">16dp</string>
    <string name="boxWidth">40dp</string>
    <string name="boxHeight">34dp</string>
    <string name="tBoxWidth">128dp</string>
</resources>

我已经尝试了以上内容；我尝试做一个扩展TextView的自定义类；我试过做一个TextView和ImageView；我尝试做android:drawableEnd。但是，每种方法都会出现一些错误，使我无法使用所述方法。我在做什么错？？

Answer 1

显然，这是一个SDK问题。我的最低SDK为19。为了在可绘制对象中使用android:width和android:height，我的最低SDK必须为23。

TextView不允许使用其中的位图绘制图层列表背景
