我想在 TextView 中动态显示文本。文本将动态地来自服务器。这可能是一个单词或一行或一个段落。文本根据客户要求显示大小为 56sp 的 View 。

我的问题是，应用程序以巨大的尺寸显示文本。在行尾出现断字的情况下，操作系统不会在下面的 Marshmallow 设备中自动显示连字符("-")。

例如:文本:“结转数据现已可用” 它在 UI 中显示为

结转

现在的数据ava

无法

我想显示为

结转

数据现在可用-

不能。

但这在 Marshmallow 或更高版本的设备上正常工作。

TextView 属性如下所示

<TextView
     android:id="@+id/tv_primary_headline"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:layout_alignParentTop="true"
     android:fontFamily="sans-serif-black"
                  android:lineSpacingExtra="@dimen/promo_primarytext_line_spacing"
     android:textAppearance="?android:attr/textAppearanceLarge"
     android:textColor="@color/navigation_selection_color"
     android:textSize="@dimen/promo_primary_headline_size"
     android:textStyle="bold"
     android:visibility="visible" />

 TextView mTvPrimaryHeadline = (TextView) view.
                    findViewById(R.id.tv_primary_headline);
  this.mTvPrimaryHeadline.setText(Html.fromHtml(title));

最佳答案

我采用了另一种方法来解决这个问题。

为了推广所有设备的实现，根据句子中最长的单词动态排列文本。请使用以下两种方法并传递完整的句子和使用 TextView。这将自动为所有屏幕排列所有设备的文本。

/**

     *              The message will split and rearrange the size based on its character length
     */
    private void updateText(String message, TextView mTvMessageText ) {
        try {
            if (message == null || message.length() == 0) {
                return;
            }

            String word = getLongestWordLength(message);

            if (word == null) {
                return;
            }
            String wordUpper = word.toUpperCase();// Convert the word to uppercase to find the Maximum Space
            // mTvMessageText - TextView need to Update the Value
            float width = ((mTvMessageText.getMeasuredWidth()) - 120); // Get the width of the View with reduced padding
