android - 带有 LinkMovementMethod 的 justificationMode 使文本被截断

Question

我想同时实现文本对齐和向 TextView 添加链接(显示更多)，所以我将 justificationMode 与 movementMethod 一起使用。justificationMode 运行良好，但在设置 movementMethod 后，我的 TextView 每一行的最后一个字符被剪切。

val textView = findViewById<TextView>(R.id.myTextView)
textView.text = "Lorem ipsum dolor sit amet, consectetuabc adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum."
textView.justificationMode = JUSTIFICATION_MODE_INTER_WORD
textView.movementMethod = LinkMovementMethod()

xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:id="@+id/myTextView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginHorizontal="16dp"
        android:layout_marginTop="10dp"
        android:textSize="20sp" />

</LinearLayout>

8 个月后，这个问题仍然存在，我只是在 SDK 31 上遇到了它。android:autoLink="all" 解决方法对我不起作用，对我的应用程序也不满意.这是我的解决方法；它并不完美，但它为我解决了这个问题，我认为这里足以解决 OP 的问题，同时为其他人提供指导:

<强>1。给TextView添加OnTouchListener

// A lot of this code was lifted from LinkMovementMethod.onTouchEvent
binding.tv.setOnTouchListener { tv, event ->
        require(tv is TextView)
        val action = event.action
        if (action == MotionEvent.ACTION_UP) {
            val x = event.x.toInt() - tv.totalPaddingLeft + tv.scrollX
            val y = event.y.toInt() - tv.totalPaddingTop + tv.scrollY
            val line = tv.layout.getLineForVertical(y)
            val offset = tv.layout.getOffsetForHorizontal(line, x.toFloat())
            val spannable = tv.text as SpannedString // Risky business
            val links: Array<ClickableSpan> = spannable.getSpans(offset, offset, ClickableSpan::class.java)
            if (links.isNotEmpty()) {
                logger.debug("x=${event.x}; y=${event.y}")
                links.first().onClick(tv)
            }
        }
        true
    }

<强>2。将 ClickableSpans 添加到 TextView

val builder = SpannableStringBuilder()
builder.setSpan(object : ClickableSpan() {
    // You can cache data here using closure
    val textOrUrl = "Clicked!"
    override fun onClick(widget: View) {
        // Do stuff
        Toast.makeText(widget.context, textOrUrl, Toast.LENGTH_SHORT).show()
    }

    // optional override if you don't want your links formatted
    override fun updateDrawState(ds: TextPaint) = Unit
}, beginIndex, endIndex, 0)
// Add builder to TextView 
binding.tv.text = builder
