如何很好地缩放适用于 Android 的 TextView 的背景图像 [英] How to nicely scale a background image of a TextView for Android

问题描述

我正在努力为我的 Android 应用扩展 TextView.我想创建气泡"以在对话中显示文本消息，类似于本机 iPhone SMS 对话.

I'm battleing with extending a TextView for my Android app. I'd like to create "bubbles" to display text messages in a conversation, similar to the native iPhone SMS conversations.

有没有办法在不拉伸背景图像的情况下实现背景图像的大小调整?我想要一个单一的背景图像，保留它的角落，但只在定义的区域中拉伸.我认为这应该是可能的，因为我在 SMS 应用程序中见过它，但我不知道如何实现.

Is there a way to implement the resizing of a background image without just stretching it? I'd like to have a single background image that keeps it's corners but get stretched only in defined areas. I think this should be possible because I've seen it in a SMS app, but I wonder how to implement that.
