android ellipsize multiline textview

Question

I need to ellipsize a multi-line textview  My component is large enough to display at least 4 lines with the ellipse  but only 2 lines are displayed  I tried to change the minimum and maximum number of rows of the component but it changes nothing

Extend TextView and override these methods   CharSequence origText       int maxLines   2    Override public void setText CharSequence text  BufferType type        super setText text  type       origText   text      Override protected void onMeasure int widthMeasureSpec  int heightMeasureSpec        super onMeasure widthMeasureSpec  heightMeasureSpec        CharSequence text   origText      onPreDraw         while getLineCount    gt  maxLines            text   text subSequence 0  text length  -1           super setText text                   super onMeasure widthMeasureSpec  heightMeasureSpec           onPreDraw

There are a few attributes you should check  android lines  android minLines  android maxLines  To display a maximum of 4 lines and ellipsize it  you just need android maxLines and android ellipsize    lt TextView     android layout width  fill parent      android layout height  wrap content      android maxLines  4      android ellipsize  marquee      android text  Hai         gt

In my case  there is no need to code this in Java  Everything works as expected  No need for something like android singleLine  false     lt TextView   android layout width  match parent    android layout height  wrap content    android ellipsize  end    android maxLines  4    android text   string very long text    gt    But there seems to be a bug in the layout preview of Android Studio  v3 0     Given Android 7 1 1 on my device this is working

Here is a solution to the problem   It is a subclass of TextView that actually works for ellipsizing   The android-textview-multiline-ellipse code listed in an earlier answer I have found to be buggy in certain circumstances  as well as being under GPL  which doesn t really work for most of us   Feel free to use this code freely and without attribution  or under the Apache license if you would prefer   Note that there is a listener to notify you when the text becomes ellipsized  which I found quite useful myself   import java util ArrayList  import java util List   import android content Context  import android graphics Canvas  import android text Layout  import android text Layout Alignment  import android text StaticLayout  import android text TextUtils TruncateAt  import android util AttributeSet  import android widget TextView   public class EllipsizingTextView extends TextView       private static final String ELLIPSIS               public interface EllipsizeListener           void ellipsizeStateChanged boolean ellipsized              private final List lt EllipsizeListener gt  ellipsizeListeners   new ArrayList lt EllipsizeListener gt         private boolean isEllipsized      private boolean isStale      private boolean programmaticChange      private String fullText      private int maxLines   -1      private float lineSpacingMultiplier   1 0f      private float lineAdditionalVerticalPadding   0 0f       public EllipsizingTextView Context context            super context              public EllipsizingTextView Context context  AttributeSet attrs            super context  attrs              public EllipsizingTextView Context context  AttributeSet attrs  int defStyle            super context  attrs  defStyle              public void addEllipsizeListener EllipsizeListener listener            if  listener    null                throw new NullPointerException                      ellipsizeListeners add listener              public void removeEllipsizeListener EllipsizeListener listener            ellipsizeListeners remove listener              public boolean isEllipsized             return isEllipsized              Override     public void setMaxLines int maxLines            super setMaxLines maxLines           this maxLines   maxLines          isStale   true             public int getMaxLines             return maxLines              Override     public void setLineSpacing float add  float mult            this lineAdditionalVerticalPadding   add          this lineSpacingMultiplier   mult          super setLineSpacing add  mult               Override     protected void onTextChanged CharSequence text  int start  int before  int after            super onTextChanged text  start  before  after           if   programmaticChange                fullText   text toString                isStale   true                        Override     protected void onDraw Canvas canvas            if  isStale                super setEllipsize null               resetText                      super onDraw canvas              private void resetText             int maxLines   getMaxLines            String workingText   fullText          boolean ellipsized   false          if  maxLines    -1                Layout layout   createWorkingLayout workingText               if  layout getLineCount    gt  maxLines                    workingText   fullText substring 0  layout getLineEnd maxLines - 1   trim                    while  createWorkingLayout workingText   ELLIPSIS  getLineCount    gt  maxLines                        int lastSpace   workingText lastIndexOf                           if  lastSpace    -1                            break                                            workingText   workingText substring 0  lastSpace                                     workingText   workingText   ELLIPSIS                  ellipsized   true                                  if   workingText equals getText                   programmaticChange   true              try                   setText workingText                 finally                   programmaticChange   false                                  isStale   false          if  ellipsized    isEllipsized                isEllipsized   ellipsized              for  EllipsizeListener listener   ellipsizeListeners                    listener ellipsizeStateChanged ellipsized                                      private Layout createWorkingLayout String workingText            return new StaticLayout workingText  getPaint    getWidth   - getPaddingLeft   - getPaddingRight                    Alignment ALIGN NORMAL  lineSpacingMultiplier  lineAdditionalVerticalPadding  false               Override     public void setEllipsize TruncateAt where               Ellipsize settings are not respected

I have had the same Problem  I fixed it by just deleting  android ellipsize  marquee

User · Answer

Just add code in your activity  Textview setEllipsize TextUtils TruncateAt END    this will add ellipsis at the end of the textview

Try this  it works for me  I have 4 lines and it adds the       to the end of the last fourth line   Its the same as morale s answer but i have singeLine  false  in there    lt TextView  android layout width  fill parent   android layout height  wrap content   android maxLines  4   android ellipsize  marquee   android singleLine  false   android text  Hi make this a very long string that wraps at least 4 lines  seriously make it really really long so it gets cut off at the fourth line not joke   Just do it     gt

The top answer here from Micah Hainline works great  but even better is the library that was built from it by user aleb as he posted in the comments under Micahs answer      I created an Android library with this component and changed it to be   able to show as many lines of text as possible and ellipsize the last   one  see github com triposo barone   There are some more features to it  if you only need the TextView  it is here   Maybe this will help others find it faster than I did  -

Got this problem to  and finaly  I build myself a short solution   You just have to ellipsize manually the line you want  your maxLine attribute will cut your text   This example cut your text for 3 lines max          final TextView title    TextView findViewById R id text           title setText  A really long text            ViewTreeObserver vto   title getViewTreeObserver            vto addOnGlobalLayoutListener new OnGlobalLayoutListener                   Override             public void onGlobalLayout                     ViewTreeObserver obs   title getViewTreeObserver                    obs removeGlobalOnLayoutListener this                   if title getLineCount    gt  3                       Log d     Line   title getLineCount       title getText                         int lineEndIndex   title getLayout   getLineEnd 2                       String text   title getText   subSequence 0  lineEndIndex-3                             title setText text                       Log d     NewText   text

Code worked very well  You can overload onSizeChanged method  if not only Text has to be Changed    Override protected void onSizeChanged  int w  int h  int oldw  int oldh        isStale   true      super onSizeChanged w  h  oldw  oldh

You need to include this in your textview   android singleLine  false    by default its true  You need to explicitly set it false

Based on the solutions by Micah Hainline and alebs comment  I came of with the following approach that works with Spanned texts  so that e g  myTextView setText Html fromHtml   lt b gt Testheader lt  b gt  -
