我认为如果您使用字体而不是所有图像，这可能会更容易。我相信你可以通过使用你投入时间的 TextView 然后改变背景来达到同样的效果。

有关如何使用资产文件夹中的字体，请参阅http://www.youtube.com/watch?v=kOJGmVXuuFA

编辑（新答案）：在 xml 布局中为您的时钟创建 ImageButtons，具体取决于您的时钟有多少位数。

    int[] x = {....} \\the digits you wish to display
    int[] images = { R.drawable.0, R.drawable.1,...,R.drawable.9); //the saves of your images 0-9
    int[] btnArray = { R.id.b1, R.id.b2,...}; //the ImageButtons used to display your digits
    for(int i = 0; i < numberofbuttons; i++) {
        ImageButton btn = (ImageButton) findViewById(btnArray[i-1]);
        btn.setBackgroundDrawable(getResources().getDrawable(
                images[x[i]])); 
    }
