setTextColor / setTextAppearance不能以编程方式添加TextView

Question

我一直在尝试动态创建我的表，方法是将TextView添加到线性布局作为列表标题。

我试图将TextView的文字颜色设置为白色（代码在下方），但它仍然是相同的黑色文字。

我的TextView包装器：

public static class HeaderTextView implements HeaderBox {

    Context mContext;

    TextView textView;
    protected String text;

    public HeaderTextView(Context context, String text, int widthCoefficient) {
        this.text = text;
        this.mContext = context;

        textView = new TextView(context);
        textView.setTextColor(ContextCompat.getColor(context, R.color.white));
        textView.setTextAppearance(context, android.R.style.TextAppearance_DeviceDefault_Medium);

        textView.setLayoutParams(
                new ViewGroup.LayoutParams(
                        Sizer.dpAsPixels(
                                context,
                                widthCoefficient * Grid.COLUMN_WIDTH
                        ),
                        ViewGroup.LayoutParams.WRAP_CONTENT
                )
        );

        textView.setText(text);

    }

public View toView() {
    return textView;
}

由另一个函数使用：

public static View createGridHeader(Context context, HeaderBox... columns) {
    LinearLayout tableHeader = new LinearLayout(context);

    tableHeader.setOrientation(LinearLayout.HORIZONTAL);
    tableHeader.setLayoutParams(new LinearLayout.LayoutParams(
            LinearLayout.LayoutParams.WRAP_CONTENT,
            LinearLayout.LayoutParams.WRAP_CONTENT
    ));
    tableHeader.setBackgroundColor(context.getResources().getColor(R.color.colorPrimary));
    tableHeader.setGravity(Gravity.BOTTOM);

    for(int i = 0; i < columns.length; i++) {
        tableHeader.addView(columns[i].toView());
    }

    return tableHeader;
}

最后，我将这些视图添加到LinearLayout：

@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {

    ListView raporList = (ListView) view.findViewById(R.id.grid_rapor);
    LinearLayout raporHeader = (LinearLayout) view.findViewById(R.id.main_linear);

    raporHeader.addView(
            Grid.createGridHeader(
                    getContext(),
                    new Grid.HeaderEditBox(getContext(), "TEEEEST", 4),
                    new Grid.HeaderEditBox(getContext(), "Teeest 2", 14),
                    new Grid.HeaderTextView(getContext(), "DENEME :)", 4)
            ),0
    );

    view.invalidate();

    super.onViewCreated(view, savedInstanceState);
}

setTextColor或setTextAppearance似乎都不起作用。

提前谢谢。
