How to break lines at a given character if the text is forced to wrap in your textview? (android)

Question

So I have my textview's height set to wrap content. It displays a sports score in the format "CHI 99 CHA 88". I have the textview match the parent for its width. I also have the score text set to a specific textsize in "sp" units.

So on smaller phones, if there are more characters in the score, or if font size (accessibility settings) is changed, there is a chance that the text will need to wrap into 2 lines. However, I would like a way to control where (in the string) it will decide to wrap the text and make a new line. It would look best in the form "CHI 99\\nCHA 88". But I prefer the text to be on the same line unless it is forced to wrap by screen size, character count, or accessibility settings, so I don't want to hardcode in a "\\n" from the beginning.

So basically, is there a way to control what character the text decides to create a new line at if there is a necessity for the text to wrap onto a new line.

Thanks for any responses!

Answer 1

you can avoid line breaks by use autosize and set maxLines to 1 like this:

<TextView
    android:layout_width="match_parent"
    android:layout_height="200dp"
    android:autoSizeTextType="uniform"
    android:autoSizeMinTextSize="12sp"
    android:autoSizeMaxTextSize="100sp"
    android:autoSizeStepGranularity="2sp"
    android:maxLines="1"  />

Answer 2

您可以根据屏幕宽度计算一行中的字符，然后添加新行字符。

Instead of programatically calculating display sizes/characters, etc., Flow widget with two TextViews can be used control this.

An example layout:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="150dp"
    android:layout_height="match_parent">

    <androidx.constraintlayout.helper.widget.Flow
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        app:constraint_referenced_ids="text1,text2"
        app:flow_horizontalBias="0"
        app:flow_horizontalGap="5dp"
        app:flow_horizontalStyle="packed"
        app:flow_wrapMode="chain"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <TextView
        android:id="@+id/text1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="CHI 99" />

    <TextView
        android:id="@+id/text2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="CHA 88" />
</androidx.constraintlayout.widget.ConstraintLayout>

Normally, with default sizing, it looks like this:

If the views cannot fit horizontally, second TextView moves to the next line:
