如何在Android上动态添加图片的图片资源？

我有点自大。首先，我会发布截图，然后问我的问题

---

您可以看到一些椭圆形被选中。我所做的是维护两组图像，当用户单击时，白色图像变成黑色<现在，我需要从这张答题纸上收集答案，并想知道如何收集答案。我尝试了一个名为

getImageResource（）

的方法，但该方法不存在。请帮我怎么走

代码：

 public class QuizActivity extends Activity implements OnClickListener {
/** Called when the activity is first created. */
RelativeLayout r2;
// Global variable(s)
int[][] quizData; // Storing the quiz specifications in an integer array
int[][] questionImages = {
        { R.drawable.a, R.drawable.b, R.drawable.c, R.drawable.d,
                R.drawable.e, R.drawable.f, R.drawable.g, R.drawable.h,
                R.drawable.i, R.drawable.j },
        { R.drawable.a_checked, R.drawable.b_checked, R.drawable.c_checked,
