Android的Spannablecontent带有圆角 [英] Android Spannablecontent With Rounded Corners

问题描述

我想改变我的字符串使用Spannable字符串，使与一些中间徽章。我可以突出显示相应的字母/数字通过设置BackGroundColorSpan，但需要别人帮助了一点prettier。我希望有圆角与填充围绕整个造型一点点。

这篇文章是非常接近我想要做的事：<一href="http://stackoverflow.com/questions/19292838/android-spannablestring-set-background-behind-part-of-text">Android SpannableString设置文本背后的一部分背景

我真的需要保留的资源作为一个TextView因为它与我的应用程序交互的方式。

任何想法如何利用ReplacementSpan我的特殊情况？

下面是我的code片断：

 如果（menu​​Item.getMenuItemType（）== SlidingMenuItem.MenuItemType.NOTIFICATIONS）{
                myMenuRow.setTypeface（NULL，Typeface.NORMAL）;
                myMenuRow.setTextColor（。的getContext（）getResources（）的getColor（R.color.BLACK））;
                myMenuRow.setActivated（假）;
                SpannableString spannablecontent =新SpannableString（myMenuRow.getText（））;
                spannablecontent.setSpan（新BackgroundColorSpan（Color.argb（150,0,0,0）），18，myMenuRow.length（），Spannable.SPAN_EXCLUSIVE_EXCLUSIVE）;
                myMenuRow.setText（spannablecontent）;
 

解决方案

阅读开始有点帮助，转换器的C＃后，我想出了这一点。我仍然有一些调整的事情，但如果有人还找了类似的回答。

I am trying to change my string to make a badge with a number in the middle by using Spannable String. I can highlight the appropriate letter/number by setting the BackGroundColorSpan, but need help making it a little prettier. I was hoping to have rounded corners with a little bit of padding around the entire shape.

This article is really close to what I'm trying to do: Android SpannableString set background behind part of text

I really need to keep the resource as a TextView due to the way it interacts with my application.

Any ideas how to utilize ReplacementSpan for my particular situation?

Here is my code snippet:

            if (menuItem.getMenuItemType() == SlidingMenuItem.MenuItemType.NOTIFICATIONS) {
                myMenuRow.setTypeface(null, Typeface.NORMAL);
                myMenuRow.setTextColor(getContext().getResources().getColor(R.color.BLACK));
                myMenuRow.setActivated(false);
                SpannableString spannablecontent = new SpannableString(myMenuRow.getText());
                spannablecontent.setSpan(new BackgroundColorSpan(Color.argb(150,0,0,0)), 18, myMenuRow.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
                myMenuRow.setText(spannablecontent);

解决方案

After reading getting a little help with a converter for C#, I came up with this. I still have some tweaking to do, but if anyone is also looking for a similar answer.

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);
    }
}
