You can get this done using html string and setting the html to Textview using 
<code>txtView.setText(Html.fromHtml("Your html string here"));</code>

For example :

<pre><code>txtView.setText(Html.fromHtml("&lt;html&gt;&lt;body&gt;&lt;font size=5 color=red&gt;Hello &lt;/font&gt; World &lt;/body&gt;&lt;html&gt;"));`

 tv.setText(ss1);

You can split string using space and add span to the string you require.

<pre><code> String s= "Hello Everyone"; 
 String[] each = s.split(" ");
</code></pre>

Now apply <code>span</code> to the <code>string</code> and add the same to <code>textview</code>.

Just in case you're wondering how you can set multiple different sizes in the same textview, but using an absolute size and not a relative one, you can achieve that using <a href="http://developer.android.com/reference/android/text/style/AbsoluteSizeSpan.html" rel="noreferrer"><code>AbsoluteSizeSpan</code></a> instead of a <code>RelativeSizeSpan</code>.

Just get the dimension in pixels of the desired text size

<pre><code>int textSize1 = getResources().getDimensionPixelSize(R.dimen.text_size_1);
int textSize2 = getResources().getDimensionPixelSize(R.dimen.text_size_2);
</code></pre>

and then create a new <code>AbsoluteSpan</code> based on the text

<pre><code>String text1 = "Hi";
String text2 = "there";

SpannableString span1 = new SpannableString(text1);
span1.setSpan(new AbsoluteSizeSpan(textSize1), 0, text1.length(), SPAN_INCLUSIVE_INCLUSIVE);

SpannableString span2 = new SpannableString(text2);
span2.setSpan(new AbsoluteSizeSpan(textSize2), 0, text2.length(), SPAN_INCLUSIVE_INCLUSIVE);

// let's put both spans together with a separator and all
CharSequence finalText = TextUtils.concat(span1, " ", span2);

I have written my own function which takes 2 strings and 1 int (text size)

The full text and the part of the text you want to change the size of it.

It returns a SpannableStringBuilder which you can use it in text view.

<pre><code> public static SpannableStringBuilder setSectionOfTextSize(String text, String textToChangeSize, int size){

 SpannableStringBuilder builder=new SpannableStringBuilder();

 if(textToChangeSize.length() &gt; 0 &amp;&amp; !textToChangeSize.trim().equals("")){

 //for counting start/end indexes
 String testText = text.toLowerCase(Locale.US);
 String testTextToBold = textToChangeSize.toLowerCase(Locale.US);
 int startingIndex = testText.indexOf(testTextToBold);
 int endingIndex = startingIndex + testTextToBold.length();
 //for counting start/end indexes

 if(startingIndex &lt; 0 || endingIndex &lt;0){
 return builder.append(text);
 }
 else if(startingIndex &gt;= 0 &amp;&amp; endingIndex &gt;=0){

 builder.append(text);
 builder.setSpan(new AbsoluteSizeSpan(size, true), startingIndex, endingIndex, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
 }
 }else{
 return builder.append(text);

 return builder;

blocks|key|108375|text|要做到这一点，最好的方法是不带子串的Html和完全动态的，例如：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|108376|++public+static+String+getTextSize(String+text,int+size)+{
+++++++++return+"<span+style=\"size:"%2Bsize%2B"\"+>"%2Btext%2B"";

++++}|code-block|syntax|javascript|108377|你可以使用颜色属性，等等。如果从另一方面来说：|108378|size.setText(Html.fromHtml(getTextSize(ls.numProducts,100)+%2B+"+"+%2B+mContext.getString(R.string.products));++|108379|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

The best way to do that is Html without substring your text and fully dynamique 
For example :

<pre class="lang-java prettyprint-override"><code> public static String getTextSize(String text,int size) {
 return "&lt;span style=\"size:"+size+"\" &gt;"+text+"&lt;/span&gt;";

 }
</code></pre>

and you can use color attribut etc...
if the other hand :

<pre class="lang-java prettyprint-override"><code>size.setText(Html.fromHtml(getTextSize(ls.numProducts,100) + " " + mContext.getString(R.string.products)); 
</code></pre>

In case you want to avoid too much confusion for your translators, I've come up with a way to have just a placeholder in the strings, which will be handled in code.

So, supposed you have this in the strings:

<pre><code> &lt;string name="test"&gt;
 &lt;![CDATA[
 We found %1$s items]]&gt;
 &lt;/string&gt;
</code></pre>

And you want the placeholder text to have a different size and color, you can use this:

<pre><code> val textToPutAsPlaceHolder = "123"
 val formattedStr = getString(R.string.test, "$textToPutAsPlaceHolder&lt;bc/&gt;")
 val placeHolderTextSize = resources.getDimensionPixelSize(R.dimen.some_text_size)
 val placeHolderTextColor = ContextCompat.getColor(this, R.color.design_default_color_primary_dark)
 val textToShow = HtmlCompat.fromHtml(formattedStr, HtmlCompat.FROM_HTML_MODE_LEGACY, null, object : Html.TagHandler {
 var start = 0
 override fun handleTag(opening: Boolean, tag: String, output: Editable, xmlReader: XMLReader) {
 when (tag) {
 "bc" -&gt; if (!opening) start = output.length - textToPutAsPlaceHolder.length
 "html" -&gt; if (!opening) {
 output.setSpan(AbsoluteSizeSpan(placeHolderTextSize), start, start + textToPutAsPlaceHolder.length, 0)
 output.setSpan(ForegroundColorSpan(placeHolderTextColor), start, start + textToPutAsPlaceHolder.length, 0)
 }
 }
 }
 })
 textView.text = textToShow
</code></pre>

And the result:
