A TextView that automatically fit its font and line count based on its available size and content

autofittextview's Issues

Setting maxlines and ellipsize doesn't ellipsize the end of the TextView

I added
android:maxLines="5"
android:ellipsize="end"

to put an ellipsis when the text reaches more than 5 lines, but it simply doesn't work or sometimes ellipsis is not in the right place (in the middle of the sentence)

This library failed if only emojies text

I am using this library in my project. But library is not working if string has only emojis.

"message":"😉😊"

See 1 user send only emojis. and app crashed in production version. Android 10

Doesn't auto resize in the first time

• I am trying to use AutoResizeTextView on a simple activity, but it fails on the first go. If the button is touched to auto resize there is no problem. But, the thing is, i need it to be resized when the activity is first created.
• Here is the list of things i have tried: Created AutoRiseTextView in xml as a CustomView. Called "show_the_text" method twice on the start. Called the method twice with different texts. Moved container decleration to inside of onCreate. Used RelativeLayout insted of FrameLayout. Created a temporary TextView inside of FrameLayout with text in it.
• I run the application on API23 emulator and API21 phone but result is the same.
• I have to say that i am a begginer in programming. Any ideas are welcome.

AutoResizeTextView doesn't scale property if I set custom LetterSpacing

Since android support Letter Spacing from api 21, I needed to implement custom logic for that. I used stackoverflow solution. After applying LetterSpacing text is too small.

When AutoResizeTextView is used in a custom view for a TabLayout.Tab, the text progressively gets smaller as the tab is selected and reselected

Layout of custom view for Tab:

<AutoResizeTextView xmlns:android="http://schemas.android.com/apk/res/android"
                                                 xmlns:tools="http://schemas.android.com/tools"
                                                 android:id="@+id/tab_title"
                                                 android:layout_width="wrap_content"
                                                 android:layout_height="wrap_content"
                                                 android:layout_gravity="center"
                                                 android:maxLines="1"
                                                 android:textSize="18sp"
                                                 android:textStyle="bold"/>

Code for setting up TabLayout in Activity:

_tabLayout.setupWithViewPager(_viewPager);
_tabLayout.setTabGravity(TabLayout.GRAVITY_CENTER);
_tabLayout.setOnTabSelectedListener(new TabLayout.ViewPagerOnTabSelectedListener(_viewPager)
        {
            @Override
            public void onTabSelected(TabLayout.Tab tab)
            {
                _viewPager.setCurrentItem(tab.getPosition(), true);

                ViewHolder viewHolder = (ViewHolder) tab.getTag();

                viewHolder.TabTitleView.setTextColor(getResources().getColor(R.color.primaryColor));

                viewHolder.TabTitleView.setText(_pageAdapter.getPage(tab.getPosition()).getSelectedTitle());
            }

            @Override
            public void onTabUnselected(TabLayout.Tab tab)
            {
                ViewHolder viewHolder = (ViewHolder) tab.getTag();

                viewHolder.TabTitleView.setTextColor(getResources().getColor(R.color.tab_title_color));
                viewHolder.TabTitleView.setText(_pageAdapter.getPage(tab.getPosition()).getTitle());
            }
        });

        for(int i = 0; i < _pageAdapter.getCount(); i++)
        {
            TabLayout.Tab tab = _tabLayout.getTabAt(i);
            tab.setCustomView(R.layout.tab_title);

            ViewHolder viewHolder = new ViewHolder(tab.getCustomView(), _tabLayout.getContext());
            viewHolder.TabTitleView.setText(_pageAdapter.getPage(i).getTitle());
            tab.setTag(viewHolder);

            if(i == 0)
                viewHolder.TabTitleView.setTextColor(getResources().getColor(R.color.primaryColor));
        }

Home widget

Hi,
I trie to add it in the home widget but I always get Problem loading widget and the widget does not get displayed.
Any ideas how to solve this problem?

Using AutoResizeTextView in Listview Adapter

When using the AutoResizeTextView inside a Listview adapter that implements correctly the corvertview, textsize goes decreasing more and more until it reaches the minimal size.

Is there a way to reset the default value?
Already tried:

textview.reAdjust();

and also

textview.setTextSize(TypedValue.COMPLEX_UNIT_SP, 28);

without success

Truncated Word

I have a layout that has two columns, they are defined as LinearLayout, see code below. I think AutoFixTextView does not take into account the size of the LinearLayout it is contained in, but one level up. This results in the word being truncated, see the attached screen-shot (it should end with PNG).

Resizing getting always smaller

Hi, i'm using your library that i found very usefull. But i've some problem with it. I'm making a back and forth between two activites and every time i came back on the first one the text is getting smaller and smaller and smaller again. Is it possible to stop this?? and with big text size like 150sp is it possible to erase the font padding top and bottom??

PS: I think import android.annotation.TargetApi is deprecated

fit for Android 5.0+

It seems that this TextView doesn't run well in Android 5.0+,How to fix it ?Thank you!

Text not show in lollipop version

Hi you made an amazing solution for the auto fit textview. It's really awesome. Today i am trying to apply this class on my sample project. It almost work perfectly on all android version except one version (it is Lollipop ). text is not display on the screen for the lollipop version. I don't know why !!!
I check there is no mistake in my sample code.
Thanks for this superb class +1

Not working if it has weblink from server

Hello,

Thanks for great library, but can you please suggest how to use this if it has weblinks? ("Go checkout my website http://google.com")

If no weblink, it working awesome.

Thanks!

Size gets crazy inside a cardView in recyclerView

Hi!,

I've a recyclerView with a lot of cardView. Each cardView has an autoResizeTextView and when I scroll fastly (down & up) the autoResizeTextView gets crazy... too much little in the most of time.

How Can I resolve this?

thanks in advance!

Bug: on certain cases, text might become in 3 lines even though it's set to max of 2 lines

Not sure when this happens, but maybe it's because I use Html.fromHtml for the text in the textView, and font-family .

Data binding to an AutoResizeTextView causes the layout to crash

On 5.1.1 with a note 5. When an AutoResizeTextView is bound through data binding, the layout crashes with an "IllegalArgumentException: Layout: -140 < 0". The textview is bound to an object with an empty value for the field.

This happens after onTestSize is called, AutoResizeTextView.java line 192 is called.

Doesn't seem to be properly filling

testing on android lollipop on a nexus 5, the text seems to be smaller than it could be.

I tried adjusting getLineWidth to getLineRight and got a result that seems to work. any idea of the difference between these two APIs?

Use for EditText

The link you provided for EditText on the main page is dead :-(
Do you have a new link? I need this on a EditText...

Add Edit Text for auto fitting

Repo ->

• https://github.com/ViksaaSkool/AutoFitEditText
• my fork
  • https://github.com/CrandellWS/AutoFitEditText
  • set lib up to be used as a git submodule
    • https://github.com/CrandellWS/AutoFitEditTextLib

For a quick how to:

# add submodule to track master branch
git submodule add -b master [URL to Git repo];

# update your submodule
git submodule update --remote 

so it goes like this:

git submodule add  https://github.com/CrandellWS/AutoFitEditTextLib 
git submodule update --remote 

See What you can do...But basically I need to use both libs because yours is TextView and the other is EditText.

Shadow behind AutoFitTextView

Hi,

I need to add a shadow behind the textview. The shadow has a quite large radius, so that it with my current solution will be clipped in many instances as the bounding box isn't increased when I add the shadow.

If this was a normal TextView I could just add some padding to it to avoid the clipping, however when I do that now the text becomes smaller. I would like to avoid that.

Anyone have any thoughts on how I should add padding without making the text smaller?

Thanks in advance!

Support for widget

Can you add a auto resize helper for widget TextView?

Bug: on rare cases, last letter of the word can wrap to the next line

To reproduce:
Run the sample on a screen like of Galaxy S3 , and just choose 3 lines.

Then you will see this:

Dependencies

Please create dependencies compile 'your.library'

maxWidth calculation in onTestSize

Do we really need to calculate maxWidth based on layout.getLineWidth(i)?
I changed the code just to

textRect.right = _widthLimit;

end everything works fine.

In fact I had an issue when the font size selected was too small when calculated value for maxWidth was > _widthLimit (btw if I calculate maxWidth based on layout.getLineMax(i) I get a value <= _widthLimit).

Anyway thanks for great lib :)

when i add onclick attribute, application crashes

hey guy, what's up?
i have problem, when i add android:onclick="..." attr in AutoResizeTextView and after the run it, when i click on the AutoResizeTextView ,application crashes and force close!
but when I change the AutoResizeTextView to TextView, the problem is fixed
i think this is a bug and should be fix it to make better library

Crashing.

i am getting

java.lang.StringIndexOutOfBoundsException: length=379; index=379
at java.lang.String.charAt(Native Method)
at com.lb.auto_fit_textview.AutoResizeTextView$1.onTestSize(AutoResizeTextView.java:89)

at com.lb.auto_fit_textview.AutoResizeTextView.adjustTextSize(AutoResizeTextView.java:213)
at com.lb.auto_fit_textview.AutoResizeTextView.onSizeChanged(AutoResizeTextView.java:251)

Sample is too complicated ;)

Can you provide a sample activity that is very simple:

1. Params in the XML
2. No variable sliders and such - just full width of the device screen - set the font size that fits.

Thanks.

Remove AllowBackup tag from library manifest

Hello, please remove allowBackup tag from library manifest, it can cause manifest merge error. However library should not care about backup at all.

Thanks.

Text size is not changing :-S

((TextView)itemModel.findViewById(R.id.item_price)).setText(details.getPrice());

I've played a bit with minTextSize and textSize values but apparently doesn't affect to the result :-S.

I'm testing it on a Nexus 5 with Android L ( API 20 )

AutoResizeTextView doesn't wrap content when setting Typeface

I am using AutoResizeTextView in FrameLayout and I am setting custom typeface.

There is space at the end of AutoResizeTextView[similar to what bottomPadding would produce].
When I don't set Typeface, it works fine.

I think the issue is, AutoResizeTextView is not considering the new Typeface in calculation, As the height of AutoResizeTextView remains same[as when system default typeface is used] when using non-default typeface, and the difference shows up as a gap, I am sure, if my default and non default typeface would be switched, then the text shown will be truncated, due to insufficient space.[I have not tested this]

Typeface issue

not supporting all typefaces

StringIndexOutOfBoundsException when trying to load String that ends with \n

Hello. I found out that when trying to load a String that ends with newline, AutoFitTextView crashes the app with a StringIndexOutOfBoundsException. This does not always happen, but I am able to reproduce this bug with the following string:

String test  = "(WLAN)\n";
myAutoFitTextView.setText(test);

My app crashes when the settext is excecuted. Thanks for this library, it's really needed on the Android platform.

The full stacktrace follows:

Hebrew words are cut in the bottom of last line

In my app I have sentence with full screen width on a welcome screen.
When text is in a Hebrew language the words are cut in the bottom of last line.

Adding bottom padding or setting clipToPadding/clipChildren don't help.

Can't use the Google autosizing TextView because it still has a "breaking the words issue".

Special case when used inside ViewPager

The code generally works great, but it's important to know that when used inside a ViewPager, the sliding gesture may not work unless special precautions are taken. The problem is that by default, singleLine is set to true and that also causes scrollHorizontally to be set to true. So in order to work around this, make sure in your XML layout you control the line count with maxLines and not singleLine property:

android:maxLines="1"
android:singleLine="false"

Changing textSize programmatically doesn't work

I'm trying to change the textSize programmatically according to the string length, but I don't see changes.

if(getItem( position ).getValue().length()<12){
textView.setTextSize(18);
}
else{
if(getItem( position ).getValue().length()>11&&getItem( position ).getValue().length()<25){
textView.setTextSize(15);
}
else{
textView.setTextSize(13);
}
}
textView.setText( getItem( position ).getValue() );
if(selectedItem==position){
textView.setTypeface(selected);
textView.setTextColor(context.getResources().getColor(R.color.white));
}
else{
textView.setTypeface(unselected);
textView.setTextColor(context.getResources().getColor(R.color.black));
}

The typeface is being changed properly, but not the textSize (and there are a lot of different string sizes).

Thanks in advance.

Dosen't work with Chinese multiline sentence

I have found a bug, when it is all Chinese sentence and more then one line, the textsize would be divided to min size.
It is because:
https://github.com/AndroidDeveloperLB/AutoFitTextView/blob/master/AutoFitTextViewLibrary/src/com/lb/auto_fit_textview/AutoResizeTextView.java#L89

in Chinese sentence, words was not linked by or -
so the method isValidWordWrap return false everytime in Chinese sentence, and then the sizebecome smaller and smaller(；′⌒`)

Possible solution for last character occasionally lost

In the core of the comparison a float is cast to an int:

for(int i=0;i<layout.getLineCount();i++)
  if(maxWidth<layout.getLineWidth(i))
    maxWidth=(int)layout.getLineWidth(i);
textRect.right=maxWidth;

This cast underestimates the width of the line and so may allow a font size to pass as small enough. The correct solution would be to round up the float I think. What do you think?

AutoResizeTextView doesn't wrap content when has new line character in the string ('\n')

I use AutoResizeTextView and set the string in strings.xml such as "This is a string\nwith new line character". The string will displayed as a very small text.

I think the issue is in isValidWordWrap method, it doesn't include (before == '\n') as a valid word wrap. I have tested by adding (before == '\n') in isValidWordWrap method as following:

public boolean isValidWordWrap(char before, char after) {
      return before == ' ' || before == '-' || before == '\n';
}

And it will work as expected.

Set text size method clarification

Hi! Please can you clarify the usage of setTextSize method in the sample project here. I just can't wrap my head around it. What I need is to auto size a text font in accordance with the given width and height bounds. But according to the sample the text size should be set beforehand.

So how can I determine the initial text size to make the autosizing work? Thanks in advance.

Uploading to maven central

Could you upload this to maven central for easy including into project

Bug: Don't chain constructors with this().

The problems caused by this() are most evident when changing the base class from TextView to it's close relative EditText. The EditText behaves rather oddly because it's never gets set up with some important default internal styles (see Android source for EditText(Context, AttributeSet)).

Your current code has the two simpler constructors calling the 3-argument constructor via 'this(context, attrs, 0)'. The derived constructors should be calling super(), not this() and also calling a common init() method which contains the autofit init code.
