使用HTML格式时从TextView删除底部填充 [英] Removing the bottom Padding from a TextView while using HTML Format

问题描述

我尝试像这样在 TextView 上设置html文本

I try set my html text on TextView like this

my_text.setText(HtmlCompat.fromHtml("<p>This is the awesome place to gain</p><p><strong>awesomeness </strong>and <em>deliciuosness. </em>very<em> </em><u>nice</u></p>", HtmlCompat.FROM_HTML_SEPARATOR_LINE_BREAK_PARAGRAPH))

我尝试为 TextView 设置边框，然后像这样填充底部.

I try set the TextView with a border, And I got padding bottom like this.

如何删除?因为我的 TextView 没有设置任何内容

How to remove that? Because My TextView doesn't set anything

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <TextView
        android:id="@+id/my_text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/border_black_fill_white"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"/>

</androidx.constraintlayout.widget.ConstraintLayout>

推荐答案

在 kotlin 中，它只是使用 trim()方法:

In kotlin it's just using trim() method:

val stringHtml = "<p>This is the awesome place to gain</p><p><strong>awesomeness </strong>and <em>deliciuosness. </em>very<em> </em><u>nice</u></p>"

val spannedHtml = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
    Html.fromHtml(stringHtml, Html.FROM_HTML_MODE_COMPACT)
} else {
    Html.fromHtml(stringHtml)
}

my_text.text = spannedHtml.trim()
