使用textview描边如何动态修改描边的宽度和颜色？

// 文字描边
public class StrokeTextView extends TextView {
private TextView outlineTextView = null;

public StrokeTextView(Context context) {
    super(context);

    outlineTextView = new TextView(context);
    init();
}

public StrokeTextView(Context context, AttributeSet attrs) {
    super(context, attrs);

    outlineTextView = new TextView(context, attrs);
    init();
}

public StrokeTextView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);

    outlineTextView = new TextView(context, attrs, defStyle);
    init();
}

public void init() {
    TextPaint paint = outlineTextView.getPaint();
    paint.setStrokeWidth(3);// 描边宽度
    paint.setStyle(Style.STROKE);
    outlineTextView.setTextColor(Color.parseColor("#7F00FF"));// 描边颜色
    outlineTextView.setGravity(getGravity());
}

@Override
public void setLayoutParams(ViewGroup.LayoutParams params) {
    super.setLayoutParams(params);
    outlineTextView.setLayoutParams(params);
}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);

    // 设置轮廓文字
    CharSequence outlineText = outlineTextView.getText();
    if (outlineText == null || !outlineText.equals(this.getText())) {
        outlineTextView.setText(getText());
        postInvalidate();
    }
    outlineTextView.measure(widthMeasureSpec, heightMeasureSpec);
}

@Override
protected void onLayout(boolean changed, int left, int top, int right, int bottom) {
    super.onLayout(changed, left, top, right, bottom);
    outlineTextView.layout(left, top, right, bottom);
}

@Override
protected void onDraw(Canvas canvas) {
    outlineTextView.draw(canvas);
    super.onDraw(canvas);
}

}

想在代码中调用这个textview的时候 通过修改参数 动态修改描边宽度和描边颜色这两个值，自己尝试了一下有没有成功，求大神指点一下。。

看看这样行不行：

    public void setStrokeWidthAndColor(int width,int colorValue){
        TextPaint paint = outlineTextView.getPaint();
        paint.setStrokeWidth(width);// 描边宽度
        paint.setStyle(Paint.Style.STROKE);

        outlineTextView.setTextColor(colorValue);// 描边颜色

        outlineTextView.invalidate();//重画
    }
