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。

大胆的,
mySpannable.setSpan(new StyleSpan(Typeface.BOLD),termStart,termStop,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

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"
/>
使用URLSpan类获取url
val spans: Array<URLSpan> = result.getSpans(0, result.length, URLSpan::class.java)
方法
fun TextView.createClickable(string: String, action:(String)->Unit ) {
text = HtmlCompat.fromHtml(string, HtmlCompat.FROM_HTML_MODE_LEGACY)
val result = SpannableString(text)
val spans = result.getSpans(0, result.length, URLSpan::class.java)
for (span in spans) {
val link:Pair<String, View.OnClickListener> = Pair(span.url, View.OnClickListener {
action(span.url)
})
val start = result.getSpanStart(span)
val end = result.getSpanEnd(span)
val flags = result.getSpanFlags(span)
result.removeSpan(span)
val clickableSpan: ClickableSpan = object : ClickableSpan() {
override fun onClick(textView: View) {
textView.invalidate()
link.second.onClick(textView)
}
override fun updateDrawState(textPaint: TextPaint) {
super.updateDrawState(textPaint)
textPaint.isUnderlineText = false
}
}
result.setSpan(clickableSpan, start, end, flags)
this.movementMethod = LinkMovementMethod.getInstance()
this.setText(result, TextView.BufferType.SPANNABLE)
}
}

示例文本:Android是一个软件堆栈，它非常棒
包装你的可点击的文本内锚标签
比如:Android是一个软件<a href='https://example.com/stack'> Stack </a>和它' <a href='https://example.com/awesome'> Awesome </a>。
val str = "Android is a Software <a href='https://example.com/stack'> Stack </a> and it' <a href='https://example.com/awesome'> Awesome </a>."
textView.createClickable(str) {
when(it) {
"https://example.com/stack"->{
startActivity(Intent(this,StackActivity::class.java))
}
"https://example.com/awesom"->{
startActivity(Intent(this,AwesomeActivity::class.java))
}
}
}
这里有一个Kotlin解决方案，与本地化工作得更好:
data class LinkedText(@StringRes val textRes: Int, val clickListener: View.OnClickListener? = null)
fun TextView.setPartiallyLinkedText(vararg texts: LinkedText) {
this.text = texts.joinToString(" ") { context.getString(it.textRes) }
val spannableString = SpannableString(this.text)
var startIndexOfLink = -1
texts.forEach { text ->
val string = context.getString(text.textRes)
if (text.clickListener != null) {
val clickableSpan = object : ClickableSpan() {
override fun updateDrawState(textPaint: TextPaint) {
textPaint.color = textPaint.linkColor
textPaint.isUnderlineText = true
}
override fun onClick(view: View) {
Selection.setSelection((view as TextView).text as Spannable, 0)
view.invalidate()
text.clickListener.onClick(view)
}
}
startIndexOfLink = this.text.toString().indexOf(string, startIndexOfLink + 1)
spannableString.setSpan(
clickableSpan, startIndexOfLink, startIndexOfLink + string.length,
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE
)
}
}
this.movementMethod = LinkMovementMethod.getInstance()
this.setText(spannableString, TextView.BufferType.SPANNABLE)
}
像这样使用它:
textView.setPartiallyLinkedText(
LinkedText(R.string.not_linked_text),
LinkedText(R.string.linked_text) {
Toast.makeText(context, "You clicked", Toast.LENGTH_LONG).show()
},
)
Java解决方案(更新2022年)
特点:
允许多个点击时，有重复的词。 可以为每个重复的单词量身定制特定的命令。
我以daler445的代码为基础，允许对重复的单词使用多个可单击的命令。
在Java课上:
public class MainActivity extends AppCompatActivity {
SharedPreferences sp;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
sp = getSharedPreferences("MyUserPrefs", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sp.edit();
TextView fulltext = (TextView) findViewById(R.id.fulltext);
//replace setText("") to setText("Android is a Software stack") for his case
fulltext.setText("Search [1] this full [1] text with repeated strings. Search [2] Search [3] full [2] full [3]");
List<Pair<String, View.OnClickListener>> links = new ArrayList<>();
//replace "Search" with "stack" for his case
String stringtohyperlink = "Search";
String stringtohyperlink2 = "full";
links.add(new Pair<>(stringtohyperlink, new View.OnClickListener() {
@Override
public void onClick(View v) {
String position = sp.getString("position","0");
if (position.equals("1")) {
Toast.makeText(MainActivity.this, "Search 1 has been Clicked.", Toast.LENGTH_SHORT).show();
editor.putString("position","0");
editor.apply();
}
if (position.equals("2")) {
Toast.makeText(MainActivity.this, "Search 2 has been Clicked.", Toast.LENGTH_SHORT).show();
editor.putString("position","0");
editor.apply();
}
if (position.equals("3")) {
Toast.makeText(MainActivity.this, "Search 3 has been Clicked.", Toast.LENGTH_SHORT).show();
editor.putString("position","0");
editor.apply();
}
}
}));
links.add(new Pair<>(stringtohyperlink2, new View.OnClickListener() {
@Override
public void onClick(View v) {
String position = sp.getString("position","0");
if (position.equals("1")) {
Toast.makeText(MainActivity.this, "full 1 has been Clicked.", Toast.LENGTH_SHORT).show();
editor.putString("position","0");
editor.apply();
}
if (position.equals("2")) {
Toast.makeText(MainActivity.this, "full 2 has been Clicked.", Toast.LENGTH_SHORT).show();
editor.putString("position","0");
editor.apply();
}
if (position.equals("3")) {
Toast.makeText(MainActivity.this, "full 3 has been Clicked.", Toast.LENGTH_SHORT).show();
editor.putString("position","0");
editor.apply();
}
}
}));
makeLinks(fulltext, links);
}
public void makeLinks(TextView textView, List<Pair<String, View.OnClickListener>> links) {
SpannableString spannableString = new SpannableString(textView.getText().toString());
int startIndexState = -1;
SharedPreferences.Editor editor = sp.edit();
for (Pair<String, View.OnClickListener> link : links) {
ClickableSpan clickableSpan = new ClickableSpan() {
@Override
public void onClick(@NonNull View widget) {
editor.putString("position","1");
editor.apply();
widget.invalidate();
assert link.second != null;
link.second.onClick(widget);
}
};
ClickableSpan clickableSpan2 = new ClickableSpan() {
@Override
public void onClick(@NonNull View widget) {
editor.putString("position","2");
editor.apply();
widget.invalidate();
assert link.second != null;
link.second.onClick(widget);
}
};
ClickableSpan clickableSpan3 = new ClickableSpan() {
@Override
public void onClick(@NonNull View widget) {
editor.putString("position","3");
editor.apply();
widget.invalidate();
assert link.second != null;
link.second.onClick(widget);
}
};
//... This only allows for 3 repeated words
//... Add more of it, if there are more repeated words.
assert link.first != null;
int startIndexOfLink = textView.getText().toString().indexOf(link.first, startIndexState + 1);
spannableString.setSpan(clickableSpan, startIndexOfLink, startIndexOfLink + link.first.length(), Spanned.SPAN_EXCLUSIVE_INCLUSIVE);
int startIndexOfLink2 = textView.getText().toString().indexOf(link.first, startIndexOfLink + 1);
if (startIndexOfLink2 != -1) {
spannableString.setSpan(clickableSpan2, startIndexOfLink2, startIndexOfLink2 + link.first.length(), Spanned.SPAN_EXCLUSIVE_INCLUSIVE);
}
int startIndexOfLink3 = textView.getText().toString().indexOf(link.first, startIndexOfLink2 + 1);
if (startIndexOfLink3 != -1) {
spannableString.setSpan(clickableSpan3, startIndexOfLink3, startIndexOfLink3 + link.first.length(), Spanned.SPAN_EXCLUSIVE_INCLUSIVE);
}
//... This only allows for 3 repeated words
//... Add more of it, if there are more repeated words.
textView.setMovementMethod(LinkMovementMethod.getInstance());
textView.setText(spannableString, TextView.BufferType.SPANNABLE);
}
}
}
在xml
<TextView
android:id="@+id/fulltext"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
Demo
大胆的,
mySpannable.setSpan(new StyleSpan(Typeface.BOLD),termStart,termStop,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
