Android, How to limit width of TextView (and add three dots at the end of text)?

Question

I have a TextView that I want to limit characters of it. Actually, I can do this but the thing that I\'m looking for is how to add three dots (...) at the end o

Answer 1

In order to work with the android:ellipsize attribute, you have to limit the layout width of the TextView, such that the text is out of bounds from view of TextView.

So, android:layout_width attribute plays a key role here, set it accordingly.

One example can be:

<TextView        
    android:layout_width="120dp"
    android:layout_height="wrap_content"
    android:ellipsize="end"
    android:text="This is a very long text to be displayed"
    android:textSize="12sp"
    android:maxLines="1"            
     />

Now, here if the text in android:text="This is a very long text to be displayed" goes out of view from TextView with a android:layout_width="120dp", android:ellipsize="end" will truncate the text and place ...(3 dots) after it. i.e. This is very long... will be displayed in the TextView.

Answer 2

You just change ...

android:layout_width="wrap_content"

Use this below line

android:layout_width="match_parent"

.......

   <LinearLayout
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_centerVertical="true"
       android:layout_marginLeft="10dp"
       android:layout_marginTop="10dp"
       android:layout_toRightOf="@+id/visitBox"
       android:orientation="vertical" >

             <TextView
                  android:id="@+id/txvrequestTitle"
                  android:layout_width="match_parent"
                  android:layout_height="wrap_content"
                  android:singleLine="true"
                  android:text="Abcdefghighiklmnon"
                  android:textAppearance="? 
                  android:attr/textAppearanceLarge"
                  android:textColor="@color/orange_color" />

   </LinearLayout>

Answer 3

The approach of @AzharShaikh works fine.

android:ellipsize="end"
android:maxLines="1"

But I realize a trouble that TextView will be truncated by word (in default). Show if we have a text like:

test long_line_without_any_space_abcdefgh

the TextView will display:

test...

And I found solution to handle this trouble, replace spaces with the unicode no-break space character, it makes TextView wrap on characters instead of words:

yourString.replace(" ", "\u00A0");

The result:

test long_line_without_any_space_abc...

Answer 4

I take it you want to limit width to one line and not limit it by character? Since singleLine is deprecated, you could try using the following together:

android:maxLines="1"
android:scrollHorizontally="true"
android:ellipsize="end"

Answer 5

I got the desired result by using

android:maxLines="2"
android:minLines="2"
android:ellipsize="end"

The trick is set maxLines and minLines to the same value... and Not just android:lines = "2", dosen't do the trick. Also you are avoiding any deprecated attributes.

Answer 6

eg. you can use

android:maxLength="13"

this will restrict texview length to 13 but problem is if you try to add 3 dots(...), it wont display it, as it will be part of textview length.

     String userName;
     if (data.length() >= 13) {
            userName = data.substring(0, 13)+ "...";

     } else {

            userName = data;

    }
        textView.setText(userName);

apart from this you have to use

 android:maxLines="1"
