Android: TextView automatically truncate and replace last 3 char of String
If a String
is longer than the TextView
's width it automatically wraps onto the next line. I can avoid this by using android:singleLine
(deprecated) or by setting android:inputType="text"
. What I need now is something that replaces the last 3 characters of my String
with "...". Since I'm not using a monospace font this will always be different depending on the letters used in my String
. So I'm wondering what's the best way to get the last 3 characters of a String in a TextView
and replace them. Maybe there's already something implemented in the Android framework, since this must be a common problem.
Solution 1:
You should be able to use the "ellipsize" property of a text view:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/text_mytext"
android:ellipsize="end"
android:maxLines="1"
/>
You may also need to apply gravity values to the layout too; I have sometimes seen "auto-stretching" views without them.
Solution 2:
Found an interesting work-a-round for this problem.
maxLines=1
ellipsize=end
scrollHorizontally=true
The trick is that last statement about horizontal scrolling .... check it out. It at least works on v2.2.
Solution 3:
Programmatically, you can use:
TextView tx = new TextView(this);
tx.setTextSize(13);
tx.setGravity(Gravity.CENTER);
tx.setTop(90);
tx.setText("Long text here");
tx.setTextColor(Color.BLACK);
tx.setSingleLine(true);
tx.setEllipsize(TruncateAt.END);
