Android:结合文本和按钮或 ImageButton 上的图像 [英] Android: combining text & image on a Button or ImageButton

问题描述

我正在尝试在按钮上放置一个图像(作为背景)，并根据运行时发生的情况动态添加图像上方/上方的一些文本.

I'm trying to have an image (as the background) on a button and add dynamically, depending on what's happening during run-time, some text above/over the image.

如果我使用 ImageButton 我什至无法添加文本.如果我使用 Button，我可以添加文本，但只能使用 android:drawableBottom 和定义的类似 XML 属性定义图像 此处.

If I use ImageButton I don't even have the possibility to add text. If I use Button I can add text but only define an image with android:drawableBottom and similar XML attributes as defined here.

然而，这些属性只结合了文本 &x 和 y 维度的图像，这意味着我可以围绕我的文本绘制图像，但不能在我的文本下方/下方(z 轴定义为从显示中出来).

However these attributes only combine text & image in x- and y-dimensions, meaning I can draw an image around my text, but not below/under my text (with the z-axis defined as coming out of the display).

关于如何做到这一点的任何建议?一种想法是扩展 Button 或 ImageButton 并覆盖 draw() 方法.但以我目前的知识水平，我真的不知道如何做到这一点(2D 渲染).也许有更多经验的人知道解决方案或至少有一些开始的指示?

Any suggestions on how to do this? One idea would be to either extend Button or ImageButton and override the draw()-method. But with my current level of knowledge I don't really know how to do this (2D rendering). Maybe someone with more experience knows a solution or at least some pointers to start?

推荐答案

您可以在 Button 上调用 setBackground() 来设置按钮的背景.

You can call setBackground() on a Button to set the background of the button.

任何文本都会出现在背景之上.

Any text will appear above the background.

如果您正在 xml 中寻找类似的东西，则有:android:background 属性，其工作方式相同.

If you are looking for something similar in xml there is: android:background attribute which works the same way.
