所以我没有在互联网上找到解决方案,所以我最终自己实现了它。
因此,我没有使用带有 MovementMethod 的简单 TextView,而是创建了一个使用 onTouchEvent 扩展文本视图的新类。
public class MyTextView extends TextView {
@Override
public boolean onTouchEvent(@NonNull MotionEvent event) {
if (linksActive) {
Layout layout = this.getLayout();
if (layout != null) {
int line = layout.getLineForVertical((int) event.getY());
int offset = layout.getOffsetForHorizontal(line, event.getX());
if (getText() != null && getText() instanceof Spanned) {
Spanned spanned = (Spanned) getText();
ClickableSpan[] links = spanned.getSpans(offset, offset, ClickableSpan.class);
if (links.length > 0) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
return true;
} else if (event.getAction() == MotionEvent.ACTION_UP) {
links[0].onClick(this);
} else {
return super.onTouchEvent(event);
}
}
}
}
}
return super.onTouchEvent(event);
}
}
我还创建了一个扩展 ClickableSpan 处理点击的类:
public class URLSpan extends ClickableSpan {
private String url;
private int spanType;
public URLSpan(String url, int spanType) {
this.url = url;
this.spanType = spanType;
}
public int getType() {
return spanType;
}
@Override
public void onClick(@NonNull View widget) {
if (widget instanceof OnSpanClickListener) {
((OnSpanClickListener) widget).onSpanClicked(url, type);
} else {
// ignored
}
}
}
在这种情况下,我必须自己管理跨度(在setText()
方法中)
public static void formatPhoneNumbers(@NonNull Spannable spannable, @ColorInt int color) {
Matcher matcher = MY_Patterns.PHONE_NO.matcher(spannable);
while (matcher.find()) {
if (!Linkify.sPhoneNumberMatchFilter.acceptMatch(spannable, matcher.start(), matcher.end())) {
continue;
}
removeSpans(spannable, SpanType.PHONE_NO, matcher.start(), matcher.end());
if (hasClickableSpans(spannable, matcher.start(), matcher.end())) {
// ignore different clickable spans overlap
continue;
}
final ForegroundColorSpan span = new ForegroundColorSpan(color);
final ClickableSpan urlSpan = new URLSpan(matcher.group(), SpanType.PHONE_NO);
spannable.setSpan(urlSpan, matcher.start(), matcher.end(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
spannable.setSpan(span, matcher.start(), matcher.end(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
}
}
private static void removeSpans(@NonNull Spannable spannable, int type, int start, int end) {
URLSpan[] arr = spannable.getSpans(start, end, URLSpan.class);
for (URLSpan span : arr) {
if (span.getType() == type) {
spannable.removeSpan(span);
}
}
}
private static boolean hasClickableSpans(@NonNull Spannable spannable, int start, int end) {
ClickableSpan[] arr = spannable.getSpans(start, end, ClickableSpan.class);
return arr.length > 0;
}
