开发工具类型的App，多少都会碰到链接、电话、邮箱等地址跳转问题，TextView中的autolink属性可以自动识别链接、手机号、邮箱...，只要一行代码即可实现。

android:autoLink="all"

但是自带的文字样式可能满足我们的需求，那么我们可以把目光移向“URLSpan”、“ClickableSpan”
只需要继承ClickableSpan并重写“updateDrawState”方法即可改变样式

方法

public class PhoneSpan extends URLSpan {
    public PhoneSpan(String url) {
        super(url);
    }

    @Override
    public void updateDrawState(TextPaint ds) {
        //设置字体颜色
        ds.setColor(Color.parseColor("#3598db"));
        //去掉下划线
        ds.setUnderlineText(false);
    }
}

使用 android:autoLink="web|phone"的控制台日志

使用

CharSequence content = textView.getText();
if (content instanceof Spannable) {
        int end = text.length();
        Spannable sp = (Spannable) content;
        URLSpan[] urls = sp.getSpans(0, end, URLSpan.class);
        SpannableStringBuilder spannableStringBuilder = new SpannableStringBuilder(content );
        spannableStringBuilder.clearSpans();
        for (URLSpan urlSpan : urls) {
           if(url.startsWith("tel:")){
            PhoneSpan phoneSpan = new PhoneSpan (urlSpan.getURL());
            spannableStringBuilder.setSpan(phoneSpan , sp.getSpanStart(urlSpan), sp.getSpanEnd(urlSpan), 
            Spannable.SPAN_EXCLUSIVE_INCLUSIVE);
            }
        }
        textView.setText(spannableStringBuilder);
    } 

那么你在设置这个Autolink的时候，如果你在TextView上设置了长按监听，那么就会出现TextView的长按事件响应了，同时当你触摸离开屏幕也就是触发了“MotionEvent.ACTION_UP”,同时你也会发现ClickableSpan点击事件也响应了，如果不相信这个你可以自己搞个demo试试。
解决方案就是重写LinkMovementMethod中的onTouchEvent方法

public class LinkMovementClickMethod extends LinkMovementMethod {
    private long lastClickTime;
    private static final long CLICK_DELAY = 500L;

    public static LinkMovementClickMethod getInstance() {
        if (null == sInstance) {
            sInstance = new LinkMovementClickMethod();
        }
        return sInstance;
    }

    private static LinkMovementClickMethod sInstance;

    @Override
    public boolean onTouchEvent(TextView widget, Spannable buffer, MotionEvent event) {
        int action = event.getAction();

        if (action == MotionEvent.ACTION_UP ||
                action == MotionEvent.ACTION_DOWN) {
            int x = (int) event.getX();
            int y = (int) event.getY();

            x -= widget.getTotalPaddingLeft();
            y -= widget.getTotalPaddingTop();

            x += widget.getScrollX();
            y += widget.getScrollY();

            Layout layout = widget.getLayout();
            int line = layout.getLineForVertical(y);
            int off = layout.getOffsetForHorizontal(line, x);

            ClickableSpan[] link = buffer.getSpans(off, off, ClickableSpan.class);

            if (link.length != 0) {
                if (action == MotionEvent.ACTION_UP) {
                    if (System.currentTimeMillis() - lastClickTime < CLICK_DELAY) {
                        link[0].onClick(widget);
                    }
                } else if (action == MotionEvent.ACTION_DOWN) {
                    Selection.setSelection(buffer,
                            buffer.getSpanStart(link[0]),
                            buffer.getSpanEnd(link[0]));
                    lastClickTime = System.currentTimeMillis();
                }
                return true;
            } else {
                Selection.removeSelection(buffer);
            }
        }
        return super.onTouchEvent(widget, buffer, event);
    }
}
