我正在尝试在图片下方添加文字，如下所示。
之前的图片：image without text below
之后的图片：image with text below
我可以在图像上绘制文字，但我无法在图像下面绘制它。请帮助我!!

您可以使用图片在TextView下方的ImageView中添加文字。例如：
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="5">
<ImageView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="4"
android:src="@drawable/your_img"/>
<TextView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:text="Your text comes here"/>
</LinearLayout>
