Android更改图像按钮背景 [英] android change image button background

问题描述

我似乎无法更改图像按钮的背景图像.这是我当前尝试使用的代码:

I cannot seem to change the background image of my image button. Heres the code i'm currently trying to use:

ImageButton imgButton = (ImageButton) findViewById(R.id.showSportsButton);
imgButton.setBackgroundResource(R.drawable.tab2_selected);

但是，这似乎是将新图像放置在旧图像之上，使我有2张彼此重叠的图像.

However this seem to be placing the new image on top of the old image leaving me with 2 images overlapping each other.

有人知道这是为什么吗?

Does anyone know why this is??
