我有文本“Android是一个软件堆栈”。在这个文本中,我想设置“堆栈”文本为可点击。所以,如果你点击它,它将重定向到一个新的活动(不在浏览器中)。
我试过了,但没有找到解决办法。

我编写了一个例子来解决你的问题在Kotlin。
这是准则:
val completeText = getString(R.string.terms_description)
val textToFind = getString(R.string.show_terms)
val spannableString: Spannable = SpannableString(completeText)
val startFocus = completeText.indexOf(textToFind)
val endFocus = startFocus + textToFind.length
spannableString.setSpan(object: ClickableSpan() {
override fun onClick(p0: View) {
showMessage()
}
}, startFocus, endFocus, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)
show_terms.text = spannableString
show_terms.movementMethod = LinkMovementMethod.getInstance();
show_terms.highlightColor = Color.TRANSPARENT;
这是XML
<CheckBox
android:id="@+id/check_agree_terms"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView
android:id="@+id/show_terms"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColorLink="@color/colorPrimary"
android:layout_toEndOf="@id/check_agree_terms"/>
这就是它的样子

这是一个Kotlin方法,使TextView的部分可点击:
private fun makeTextLink(textView: TextView, str: String, underlined: Boolean, color: Int?, action: (() -> Unit)? = null) {
val spannableString = SpannableString(textView.text)
val textColor = color ?: textView.currentTextColor
val clickableSpan = object : ClickableSpan() {
override fun onClick(textView: View) {
action?.invoke()
}
override fun updateDrawState(drawState: TextPaint) {
super.updateDrawState(drawState)
drawState.isUnderlineText = underlined
drawState.color = textColor
}
}
val index = spannableString.indexOf(str)
spannableString.setSpan(clickableSpan, index, index + str.length, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)
textView.text = spannableString
textView.movementMethod = LinkMovementMethod.getInstance()
textView.highlightColor = Color.TRANSPARENT
}
它可以被多次调用,在TextView中创建几个链接:
makeTextLink(myTextView, str, false, Color.RED, action = { Log.d("onClick", "link") })
makeTextLink(myTextView, str1, true, null, action = { Log.d("onClick", "link1") })
android.text.style.ClickableSpan可以解决你的问题。
SpannableString ss = new SpannableString("Android is a Software stack");
ClickableSpan clickableSpan = new ClickableSpan() {
@Override
public void onClick(View textView) {
startActivity(new Intent(MyActivity.this, NextActivity.class));
}
@Override
public void updateDrawState(TextPaint ds) {
super.updateDrawState(ds);
ds.setUnderlineText(false);
}
};
ss.setSpan(clickableSpan, 22, 27, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
TextView textView = (TextView) findViewById(R.id.hello);
textView.setText(ss);
textView.setMovementMethod(LinkMovementMethod.getInstance());
textView.setHighlightColor(Color.TRANSPARENT);
在XML:
<TextView
...
android:textColorLink="@drawable/your_selector"
/>
你可以像本文中描述的那样使用ClickableSpan
示例代码:
TextView myTextView = new TextView(this);
String myString = "Some text [clickable]";
int i1 = myString.indexOf("[");
int i2 = myString.indexOf("]");
myTextView.setMovementMethod(LinkMovementMethod.getInstance());
myTextView.setText(myString, BufferType.SPANNABLE);
Spannable mySpannable = (Spannable)myTextView.getText();
ClickableSpan myClickableSpan = new ClickableSpan() {
@Override
public void onClick(View widget) { /* do something */ }
};
mySpannable.setSpan(myClickableSpan, i1, i2 + 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
参考
这是一个kotlin扩展(不工作,如果文本重复)
textView.makeTextClickable(
contentText = "Hello world",
clickableText = "world",
isBoldText = true,
onClick = {
openPageInBrowser(BuildConfig.PRIVACY_POLICY_URL)
}
)
internal fun TextView.makeTextClickable(
contentText: String,
clickableText: String,
onClick: () -> Unit,
isUnderlineText: Boolean = false,
isBoldText: Boolean = false
) {
val spannableString = SpannableString(contentText)
val clickableSpan = object : ClickableSpan() {
override fun onClick(widget: View) {
onClick()
}
override fun updateDrawState(ds: TextPaint) {
super.updateDrawState(ds)
ds.isUnderlineText = isUnderlineText
ds.isFakeBoldText = isBoldText
}
}
val clickableTextStartIndex = text.indexOf(clickableText)
val clickableTextEndIndex = clickableTextStartIndex + clickableText.length
spannableString.setSpan(
clickableSpan,
clickableTextStartIndex,
clickableTextEndIndex,
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE
)
this.text = spannableString
this.movementMethod = LinkMovementMethod.getInstance()
}
对于那些正在寻找Kotlin解决方案的人来说,这里是对我有用的:
private fun setupTermsAndConditions() {
val termsAndConditions = resources.getString(R.string.terms_and_conditions)
val spannableString = SpannableString(termsAndConditions)
val clickableSpan = object : ClickableSpan() {
override fun onClick(widget: View) {
if (checkForWifiAndMobileInternet()) {
// binding.viewModel!!.openTermsAndConditions()
showToast("Good, open the link!!!")
} else {
showToast("Cannot open this file because of internet connection!")
}
}
override fun updateDrawState(textPaint : TextPaint) {
super.updateDrawState(textPaint)
textPaint.color = resources.getColor(R.color.colorGrey)
textPaint.isFakeBoldText = true
}
}
spannableString.setSpan(clickableSpan, 34, 86, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)
binding.tvTermsAndConditions.text = spannableString
binding.tvTermsAndConditions.movementMethod = LinkMovementMethod.getInstance()
binding.tvTermsAndConditions.setHighlightColor(Color.TRANSPARENT);
}
