如何确定在TextView中是否触摸了链接或纯文本

public class LinkTextView extends TextView {

    private OnLinkClickListener onLinkClickListener;

    public LinkTextView(Context context) {
        super(context);
    }

    public LinkTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public LinkTextView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    public void setOnLinkClickListener(OnLinkClickListener listener) {
        this.onLinkClickListener = listener;
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        CharSequence text = getText();
        Spannable spannable = Spannable.Factory.getInstance().newSpannable(text);
        int action = event.getAction();

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

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

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

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

            ClickableSpan[] linkSpans = spannable.getSpans(off, off, ClickableSpan.class);

            if (linkSpans.length != 0) {
                if (action == MotionEvent.ACTION_UP) {
                    linkSpans[0].onClick(this);
                    if (onLinkClickListener != null) {
                        onLinkClickListener.onLinkClick();
                    }
                } else if (action == MotionEvent.ACTION_DOWN) {
                    Selection.setSelection(spannable, spannable.getSpanStart(linkSpans[0]), spannable.getSpanEnd(linkSpans[0]));
                }
                return true;
            } else {
                Selection.removeSelection(spannable);
            }
        }

        return super.onTouchEvent(event);
    }

    public interface OnLinkClickListener {
        void onLinkClick();
    }
}

<com.example.LinkTextView
    android:id="@+id/textView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Your text with links here"
    android:autoLink="web" />

LinkTextView textView = findViewById(R.id.textView);
textView.setOnLinkClickListener(new LinkTextView.OnLinkClickListener() {
    @Override
    public void onLinkClick() {
        // 处理链接点击事件
    }
});
