带有圆角的Android Spannablecontent

带有圆角的Android Spannablecontent

在阅读了有关C＃转换器的帮助之后，我想到了这个。我仍然需要做一些调整，但是如果有人也在寻找类似的答案。

public class RoundedBackgroundSpan extends ReplacementSpan{    @Override    public int getSize(Paint paint, CharSequence text, int start, int end, Paint.FontMetricsInt fm) {        return 0;    }    @Override    public void draw(Canvas canvas, CharSequence text, int start, int end, float x, int top, int y, int bottom, Paint paint)    {        RectF rect = new RectF(x, top, x + text.length(), bottom);        paint.setColor(Color.CYAN);        canvas.drawRoundRect(rect, 20, 20, paint);        paint.setColor(Color.WHITE);        canvas.drawText(text, start, end, x, y, paint);    }}
