android – How to change letter spacing in a Textview?

Posted by: admin March 11, 2020 Leave a comment


How can i change letter spacing in a textview?
Will it help if I have HTML text in it (I cannot use webview in my code).

P.S. I’m using my own typeface in the textview with HTML text.

How to&Answers:

check out android:textScaleX

Depending on how much spacing you need, this might help. That’s the only thing remotely related to letter-spacing in the TextView.

Edit: please see @JerabekJakub’s response below for an updated, better method to do this starting with api 21 (Lollipop)


Since API 21 there is an option set letter spacing. You can call method setLetterSpacing or set it in XML with attribute letterSpacing.


More space:


Less space:



This answer is based on Pedro’s answer but adjusted so it also works if text attribute is already set:

package nl.raakict.android.spc.widget;
import android.content.Context;
import android.text.Spannable;
import android.text.SpannableString;
import android.text.style.ScaleXSpan;
import android.util.AttributeSet;
import android.widget.TextView;

public class LetterSpacingTextView extends TextView {
    private float letterSpacing = LetterSpacing.BIGGEST;
    private CharSequence originalText = "";

    public LetterSpacingTextView(Context context) {

    public LetterSpacingTextView(Context context, AttributeSet attrs){
        super(context, attrs);
        originalText = super.getText();

    public LetterSpacingTextView(Context context, AttributeSet attrs, int defStyle){
        super(context, attrs, defStyle);

    public float getLetterSpacing() {
        return letterSpacing;

    public void setLetterSpacing(float letterSpacing) {
        this.letterSpacing = letterSpacing;

    public void setText(CharSequence text, BufferType type) {
        originalText = text;

    public CharSequence getText() {
        return originalText;

    private void applyLetterSpacing() {
        if (this == null || this.originalText == null) return;
        StringBuilder builder = new StringBuilder();
        for(int i = 0; i < originalText.length(); i++) {
            String c = ""+ originalText.charAt(i);
            if(i+1 < originalText.length()) {
        SpannableString finalText = new SpannableString(builder.toString());
        if(builder.toString().length() > 1) {
            for(int i = 1; i < builder.toString().length(); i+=2) {
                finalText.setSpan(new ScaleXSpan((letterSpacing+1)/10), i, i+1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
        super.setText(finalText, BufferType.SPANNABLE);

    public class LetterSpacing {
        public final static float NORMAL = 0;
        public final static float NORMALBIG = (float)0.025;
        public final static float BIG = (float)0.05;
        public final static float BIGGEST = (float)0.2;

If you want to use it programatically:

LetterSpacingTextView textView = new LetterSpacingTextView(context);
textView.setSpacing(10); //Or any float. To reset to normal, use 0 or LetterSpacingTextView.Spacing.NORMAL
textView.setText("My text");
//Add the textView in a layout, for instance:
((LinearLayout) findViewById(R.id.myLinearLayout)).addView(textView);


after API >=21 there is inbuild method provided by TextView called setLetterSpacing

I built a custom class that extends TextView and solves this problem… Check out my answer here =)


As android doesn’t support such a thing, you can do it manually with FontCreator. It has good options for font modifying.
I used this tool to build a custom font, even if it takes some times but you can always use it in your projects.


For embedding HTML text in your textview you can use Html.fromHTML() syntax.
More information you will get from http://developer.android.com/reference/android/text/Html.html#fromHtml%28java.lang.String%29
