Android ClickableSpan 不调用 onClick

我正在创建一个 ClickableSpan，它正在用 正确的文本下划线。但是，单击不会注册。 你知道我做错了什么吗？

谢谢，维克多

下面是代码片段:

view.setText("This is a test");
ClickableSpan span = new ClickableSpan() {
@Override
public void onClick(View widget) {
log("Clicked");
}
};
view.getText().setSpan(span, 0, view.getText().length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

是否尝试在包含 span 的 TextView 上设置 MovementMethod？你需要这样做，使点击工作..。

tv.setMovementMethod(LinkMovementMethod.getInstance());

经过一些尝试和错误之后，设置 tv.setMovementMethod(LinkMovementMethod.getInstance());的顺序确实很重要。

这是我的完整代码

String stringTerms = getString(R.string.sign_up_terms);
Spannable spannable = new SpannableString(stringTerms);
int indexTermsStart = stringTerms.indexOf("Terms");
int indexTermsEnd = indexTermsStart + 18;
spannable.setSpan(new UnderlineSpan(), indexTermsStart, indexTermsEnd, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
spannable.setSpan(new ForegroundColorSpan(getColor(R.color.theme)), indexTermsStart, indexTermsEnd, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
spannable.setSpan(new ClickableSpan() {
@Override
public void onClick(View widget) {
Log.d(TAG, "TODO onClick.. Terms and Condition");
}
}, indexTermsStart, indexTermsEnd, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);


int indexPolicyStart = stringTerms.indexOf("Privacy");
int indexPolicyEnd = indexPolicyStart + 14;
spannable.setSpan(new UnderlineSpan(), indexPolicyStart, indexPolicyEnd, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
spannable.setSpan(new ForegroundColorSpan(getColor(R.color.theme)), indexPolicyStart, indexPolicyEnd, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
spannable.setSpan(new ClickableSpan() {
@Override
public void onClick(View widget) {
Log.d(TAG, "TODO onClick.. Privacy Policy");
}
}, indexPolicyStart, indexPolicyEnd, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);


TextView textViewTerms = (TextView) findViewById(R.id.sign_up_terms_text);
textViewTerms.setText(spannable);
textViewTerms.setClickable(true);
textViewTerms.setMovementMethod(LinkMovementMethod.getInstance());

功能:

fun setClickable(textView: TextView, subString: String, handler: () -> Unit, drawUnderline: Boolean = false) {
val text = textView.text
val start = text.indexOf(subString)
val end = start + subString.length


val span = SpannableString(text)
span.setSpan(ClickHandler(handler, drawUnderline), start, end, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)


textView.linksClickable = true
textView.isClickable = true
textView.movementMethod = LinkMovementMethod.getInstance()


textView.text = span
}


class ClickHandler(
private val handler: () -> Unit,
private val drawUnderline: Boolean
) : ClickableSpan() {
override fun onClick(widget: View?) {
handler()
}


override fun updateDrawState(ds: TextPaint?) {
if (drawUnderline) {
super.updateDrawState(ds)
} else {
ds?.isUnderlineText = false
}
}
}

用法:

Utils.setClickable(textView, subString, {handleClick()})

在 Kotlin 的直接接触

  val  textHeadingSpannable = SpannableString(resources.getString(R.string.travel_agent))




val clickSpan = object : ClickableSpan(){
override fun onClick(widget: View) {


// Handel your click
}
}
textHeadingSpannable.setSpan(clickSpan,104,136,Spannable.SPAN_INCLUSIVE_EXCLUSIVE)


tv_contact_us_inquire_travel_agent.movementMethod = LinkMovementMethod.getInstance()
tv_contact_us_inquire_travel_agent.text = textHeadingSpannable
