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);
        }));

        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) {

                    //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());
    }

其他回答

 t= (TextView) findViewById(R.id.PP1);

 t.setText(Html.fromHtml("<bThis is normal text </b>" +
                "<a href=\"http://www.xyz-zyyx.com\">This is cliclable text</a> "));
 t.setMovementMethod(LinkMovementMethod.getInstance());

                    ds.linkColor = ContextCompat.getColor(SignUpActivity.this, R.color.primary_main);

            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());
    }

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") })

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。

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"
/>
