我以编程方式创建了一个 TableLayout。一切运作良好。除了背景颜色和文本颜色。我希望 TableLayout 的背景颜色为黑色，每个 TextView 的文本颜色应为白色。现在我在我的colors.xml 中设置了两种颜色（#fffff 和#000000），并将我的表格的BackgroundResource 设置为黑色，并将我的所有TextViews 的TextColor 设置为白色。但唯一显示的是黑屏，其中没有任何白色文字。我在我的代码中看不到任何错误。也许你可以 ;-）

public class ShowTableActivity extends Activity {

TableLayout t1;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    t1 = createTable();
    fillTable();

    setContentView(t1);

经过大量研究解决了我的问题：

您必须输入 0xff000000（黑色）和 0xffffffff（白色），而不是使用 R.color.white 和 R.color.black。在第一个 2 ff 之后，颜色代码开始，所以你可以选择任何你想要的。

不要问我为什么要这样做。也许其他人可以在某个时候在这里解释一下。
