How to change the font size of an textview element in Android?

Question

I am trying to display 2 items in a TextView. Is their any way to change the font of the single item in a TextView?

Here is the XML which I am using

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:gravity="center_horizontal"
        android:paddingTop="5dp"
        android:paddingBottom="5dp"
        android:id="@+id/Rowtext"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:text="Listiems"
        android:background="@drawable/customshape"
         />

</LinearLayout>

Use android:textSize.

<TextView
    android:id="@+id/time"
    android:gravity="right"
    android:padding="5dp"
    android:textSize="40dp"
    android:textColor="#88ffff00"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:text="Time: 60"/>

Use sp if the user can rescale the text without breaking the UI. If rescaling the text would break the UI, use dp.

Isn't that we need to use SP for font sizes? I think it should be 40sp not 40dp – Neon Warge Feb 26 '15 at 02:03

One way is to use TextView.setText() method and feed it with HTML, like this:

import android.text.Html;

String n = "<b>bold</b> <small>small</small>";
TextView tv = (TextView) findViewById(...)
tv.setText(Html.fromHtml(n));

I often use it for some minor markup (like make part bolder or smaller)

erm, question was about changing font :-/ Shade's answer looks good! – pelotasplus Mar 20 '13 at 13:05
There is a typo in "fromHtml" method. It says formHtml instead. – mpccolorado May 08 '16 at 02:59

Use the HTML class from this link http://code.google.com/p/android-richtexteditor/source/browse/trunk/src/net/sgoliver/Html.java?r=4 . We would be able to set font size from this class. Normal android.text.Html actually ignores font size. Tried and tested and it worked for me.

TextView tv = (TextView)findViewById(R.id.textview);

String s = "<p>Some Text here<br><b>hi </b><font size =\"20\"><b><i>\"italics</i></b></font><b><i> </i></b><b><i><u>underline</u></i></b></p>";

tv.setText(Html.fromHtml(s));

You should add line in Text View Tag In XML:

android:textSize="32sp"

You can use html for this like this:

mytextView.setText(Html.fromHtml("<p> <font size="20" color="#0066FF" style="font-style:italic">Push this button</font> to start a new game.</p>"))

remove color and style attributes if you don't need them.

this is not working!! – Mohamad Ghaith Alzin Jun 17 '22 at 06:29
@MohamadGhaithAlzin 9 years old answer... I checked it still works. – Akhilesh Mani Jun 17 '22 at 06:54
No, it generates an error from the redundant double quotation. However, I've tested it with `mytextView.setText(Html.fromHtml("
Push this button to start a new game.
"));` It changes only the color but not for the size and italic! – Mohamad Ghaith Alzin Jun 17 '22 at 07:07
