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。

我会建议一种不同的方法,我认为这种方法需要更少的代码,而且更“本地化友好”。
假设你的目标活动被称为“ActivityStack”,在manifest中定义一个意图过滤器,使用一个自定义的方案(例如。“myappscheme”)
<activity
android:name=".ActivityStack">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<data android:host="stack"/>
<data android:scheme="myappscheme" />
</intent-filter>
</activity>
定义没有任何特殊标签的TextView(重要的是不要使用"android:autoLink"标签,参见:https://stackoverflow.com/a/20647011/1699702):
<TextView
android:id="@+id/stackView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/stack_string" />
然后在TextView的文本中使用带有自定义方案和主机的链接作为(在String.xml中):
<string name="stack_string">Android is a Software <a href="myappscheme://stack">stack</a></string>
和“激活”与setMovementMethod()(在onCreate()的活动或onCreateView()的片段链接):
TextView stack = findViewById(R.id.stackView);
stack.setMovementMethod(LinkMovementMethod.getInstance());
这将通过点击“stack”字打开堆栈活动。

您可以使用示例代码。您希望了解关于ClickableSpan的详细信息。请检查这份文件
SpannableString myString = new SpannableString("This is example");
ClickableSpan clickableSpan = new ClickableSpan() {
@Override
public void onClick(View textView) {
ToastUtil.show(getContext(),"Clicked Smile ");
}
};
//For Click
myString.setSpan(clickableSpan,startIndex,lastIndex,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
//For UnderLine
myString.setSpan(new UnderlineSpan(),startIndex,lastIndex,0);
//For Bold
myString.setSpan(new StyleSpan(Typeface.BOLD),startIndex,lastIndex,0);
//Finally you can set to textView.
TextView textView = (TextView) findViewById(R.id.txtSpan);
textView.setText(myString);
textView.setMovementMethod(LinkMovementMethod.getInstance());
我的功能使TextView内的多个链接 更新2020:现在这个函数能够支持多个相同的文本链接在1 TextView,但记得把链接在正确的顺序
fun TextView.makeLinks(vararg links: Pair<String, View.OnClickListener>) {
val spannableString = SpannableString(this.text)
var startIndexOfLink = -1
for (link in links) {
val clickableSpan = object : ClickableSpan() {
override fun updateDrawState(textPaint: TextPaint) {
// use this to change the link color
textPaint.color = textPaint.linkColor
// toggle below value to enable/disable
// the underline shown below the clickable text
textPaint.isUnderlineText = true
}
override fun onClick(view: View) {
Selection.setSelection((view as TextView).text as Spannable, 0)
view.invalidate()
link.second.onClick(view)
}
}
startIndexOfLink = this.text.toString().indexOf(link.first, startIndexOfLink + 1)
// if(startIndexOfLink == -1) continue // todo if you want to verify your texts contains links text
spannableString.setSpan(
clickableSpan, startIndexOfLink, startIndexOfLink + link.first.length,
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE
)
}
this.movementMethod =
LinkMovementMethod.getInstance() // without LinkMovementMethod, link can not click
this.setText(spannableString, TextView.BufferType.SPANNABLE)
}
使用
my_text_view.makeLinks(
Pair("Terms of Service", View.OnClickListener {
Toast.makeText(applicationContext, "Terms of Service Clicked", Toast.LENGTH_SHORT).show()
}),
Pair("Privacy Policy", View.OnClickListener {
Toast.makeText(applicationContext, "Privacy Policy Clicked", Toast.LENGTH_SHORT).show()
}))
XML
<TextView
android:id="@+id/my_text_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Please accept Terms of Service and Privacy Policy"
android:textColorHighlight="#f00" // background color when pressed
android:textColorLink="#0f0"
android:textSize="20sp" />

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()
}
这是java爱好者的Boom Check:D 我们可以根据自己的需要进行修改:
List<Pair<String, View.OnClickListener>> pairsList = new ArrayList<>();
pairsList.add(new Pair<>("38,50", v -> {
Intent intent = new Intent(SignUpActivity.this, WebActivity.class);
intent.putExtra("which", "tos");
startActivity(intent);
}));
pairsList.add(new Pair<>("81,95", v -> {
Intent intent = new Intent(SignUpActivity.this, WebActivity.class);
intent.putExtra("which", "policy");
startActivity(intent);
}));
makeLinks(pairsList); // Method calling
private void makeLinks(List<Pair<String, View.OnClickListener>> pairsList) {
SpannableString ss = new SpannableString(By signing up, I’m agree to PAKRISM’s Terms of Use and confirms that I have read Privacy Policy);
for (Pair<String, View.OnClickListener> pair : pairsList) {
ClickableSpan clickableSpan = new ClickableSpan() {
@Override
public void onClick(View textView) {
//Toast.makeText(MyApplication.getAppContext(), "Clicked!", Toast.LENGTH_SHORT).show();
pair.second.onClick(textView);
}
@Override
public void updateDrawState(TextPaint ds) {
ds.linkColor = ContextCompat.getColor(SignUpActivity.this, R.color.primary_main);
ds.setUnderlineText(true);
super.updateDrawState(ds);
}
};
String[] indexes = pair.first.split(",");
ss.setSpan(clickableSpan, Integer.parseInt(indexes[0]), Integer.parseInt(indexes[1]), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
}
TextView tv = findViewById(R.id.txtView);
tv.setText(ss);
tv.setMovementMethod(LinkMovementMethod.getInstance());
}
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
