如何使用新版本的 getresources().getColor？

Question

我正在尝试使用颜色元素，getresources.getColor(resource id)但 android 告诉我它已被弃用 use getresources.getColor(resource id, theme)。

我如何告诉它使用什么主题？我试过了，R.style.AppTheme但我收到一个错误，因为这是一个 int 值

public class TodoListItemView extends AppCompatTextView {
    public TodoListItemView(Context context, AttributeSet attributeSet, int ds) {
        super(context, attributeSet, ds);
        init();
    }

    public TodoListItemView(Context context) {
        super(context);
        init();
    }

    public TodoListItemView(Context context, AttributeSet attributeSet) {
        super(context, attributeSet);
        init();
    }

    private Paint marginPaint;
    private Paint linePaint;
    private int paperColor;
    private float margin;

    private void init() {
        Resources myResources = getResources();
        marginPaint = new Paint(Paint.ANTI_ALIAS_FLAG);
        marginPaint.setColor(getResources().getColor(R.color.notepad_margin));
        linePaint = new Paint(Paint.ANTI_ALIAS_FLAG);
        linePaint.setColor(myResources.getColor(R.color.notepad_lines));
        paperColor = myResources.getColor(R.color.notepad_paper);
        margin = myResources.getDimension(R.dimen.notepad_margin);
    }

    @Override
    public void onDraw(Canvas canvas) {
        canvas.drawColor(paperColor);
        canvas.drawLine(0, 0, getMeasuredHeight(), 0, linePaint);
        canvas.drawLine(0, getMeasuredHeight(), getMeasuredWidth(), getMeasuredHeight(), linePaint);

        canvas.drawLine(margin, 0, margin, getMeasuredHeight(), marginPaint);

        canvas.save();
        canvas.translate(margin, 0);

        super.onDraw(canvas);
        canvas.restore();
    }
}

任何帮助是极大的赞赏。

用 ContextCompat.getColor(context, R.color.your_color);
