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。

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);

ClickableSpan clickableSpan = new ClickableSpan() {
@Override
public void onClick(View textView) {

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" />

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" />

我做了这个helper方法，以防有人需要从字符串中开始和结束位置。
public static TextView createLink(TextView targetTextView, String completeString,
String partToClick, ClickableSpan clickableAction) {
SpannableString spannableString = new SpannableString(completeString);
// make sure the String is exist, if it doesn't exist
// it will throw IndexOutOfBoundException
int startPosition = completeString.indexOf(partToClick);
int endPosition = completeString.lastIndexOf(partToClick) + partToClick.length();
spannableString.setSpan(clickableAction, startPosition, endPosition,
Spanned.SPAN_INCLUSIVE_EXCLUSIVE);
targetTextView.setText(spannableString);
targetTextView.setMovementMethod(LinkMovementMethod.getInstance());
return targetTextView;
}
下面是你如何使用它
private void initSignUp() {
String completeString = "New to Reddit? Sign up here.";
String partToClick = "Sign up";
ClickableTextUtil
.createLink(signUpEditText, completeString, partToClick,
new ClickableSpan() {
@Override
public void onClick(View widget) {
// your action
Toast.makeText(activity, "Start Sign up activity",
Toast.LENGTH_SHORT).show();
}
@Override
public void updateDrawState(TextPaint ds) {
super.updateDrawState(ds);
// this is where you set link color, underline, typeface etc.
int linkColor = ContextCompat.getColor(activity, R.color.blumine);
ds.setColor(linkColor);
ds.setUnderlineText(false);
}
});
}
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());
