动态更改listview的分隔高度？

public class CustomDivider extends Drawable {
    private int mDividerHeight;
    private Paint mPaint;

    public CustomDivider(int dividerHeight, int dividerColor) {
        mDividerHeight = dividerHeight;
        mPaint = new Paint();
        mPaint.setColor(dividerColor);
        mPaint.setStrokeWidth(mDividerHeight);
    }

    @Override
    public void draw(Canvas canvas) {
        Rect bounds = getBounds();
        int left = bounds.left;
        int right = bounds.right;
        int top = bounds.top;
        int bottom = bounds.bottom;

        canvas.drawLine(left, top, right, bottom, mPaint);
    }

    @Override
    public void setAlpha(int alpha) {
        mPaint.setAlpha(alpha);
    }

    @Override
    public void setColorFilter(ColorFilter colorFilter) {
        mPaint.setColorFilter(colorFilter);
    }

    @Override
    public int getOpacity() {
        return PixelFormat.TRANSPARENT;
    }
}

public class MyAdapter extends BaseAdapter {
    // ...

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // ...

        // 根据需要动态设置分隔线高度
        int dividerHeight = getDividerHeight(position);
        CustomDivider customDivider = new CustomDivider(dividerHeight, Color.BLACK);
        view.setDivider(customDivider);

        return view;
    }

    private int getDividerHeight(int position) {
        // 根据position返回需要的分隔线高度
        // 可以根据需要自定义逻辑
        return position % 2 == 0 ? 10 : 20;
    }
}
