Android的添加图像按钮 [英] Android add image to button

问题描述

我要的图像添加到按钮（没有的ImageButton ，由于特定的按钮可以包含文本或图像;加上的ImageButton有同样的问题），同时仍保留了原生Android样式的按钮。所以加入的android：背景在XML不削减，因为这将与圆角等删除Android的默认按钮（android.R .drawable.btn_default）

I want to add an image to a Button (no imagebutton, as the particular button can either contain text or an image; plus the imagebutton has the same problem), while still retaining the original android-style button. So adding android:background in the XML doesn't cut it, as that will remove the android default button with rounded corners etc. (android.R.drawable.btn_default)

这是在任何可能的方式？

Is this in any way possible?

我想一个办法就是让 9patch 图像（一个用于和一个向下）按钮pressed和 onTouch ACTION_DOWN 使分层背景绘制，并将该到按钮，做同样的事情，但与另一个 9patch 为 onTouch Action_UP ，但我认为，这将大大降低应用程序的性能，这将需要相当多的资源阅读和图层合并为所有的按钮点击（和我的应用程序，那将是相当很多）。就是我上面的陈述正确？

I think one way is to make a 9patch image for the button pressed (one for up and one for down) and onTouch Action_DOWN make a layered background drawable and put that onto the button, and doing the same thing but with another 9patch for onTouch Action_UP, but I think that will decrease the performance of the application substantially, as that will require quite a lot of resource reading and layer merging for all the button clicks (and for my application, that will be quite a lot). Is what I state above correct?

编辑：我不能声明图像的源中的XML，因为我从Web服务获得的图像，所以任何事情都有可能上的按钮放，但它以编程方式发生

I can't declare the source of the image in the XML, because I get the images from a web service, so anything can be put on the Buttons, but it has to happen programmatically.

推荐答案

这可以使用机器人完成：drawableTop ，的android：drawableBottom ，的android：drawableLeft ，的android：drawableRight 在layout.xml属性。

This can be done using the android:drawableTop, android:drawableBottom, android:drawableLeft, android:drawableRight attributes in your layout.xml.
