    textView.setTypeface(null, Typeface.BOLD_ITALIC);
    textView.setTypeface(null, Typeface.BOLD);
    textView.setTypeface(null, Typeface.ITALIC);
    textView.setTypeface(null, Typeface.NORMAL);
    

    To keep the previous typeface

    textView.setTypeface(textView.getTypeface(), Typeface.BOLD_ITALIC)

    You have two options:

    Option 1 (only works for bold, italic and underline):

    String s = "<b>Bolded text</b>, <i>italic text</i>, even <u>underlined</u>!"
    TextView tv = (TextView)findViewById(R.id.THE_TEXTVIEW_ID);
    tv.setText(Html.fromHtml(s));
    

    Option 2:

    Use a Spannable; it is more complicated, but you can dynamically modify the text attributes (not only bold/italic, also colors).

    It would be

    yourTextView.setTypeface(null,Typeface.DEFAULT_BOLD);
    

    and italic should be able to be with replacing Typeface.DEFAULT_BOLD with Typeface.DEFAULT_ITALC.

    Let me know how it works.

    Use textView.setTypeface(Typeface tf, int style); to set style property of the TextView. See the developer documentation for more info.

    Try this to set on TextView for bold or italic

    textView.setTypeface(textView.getTypeface(), Typeface.BOLD);
    textView.setTypeface(textView.getTypeface(), Typeface.ITALIC);
    textView.setTypeface(textView.getTypeface(), Typeface.BOLD_ITALIC);

    TextView text = (TextView)findViewById(R.id.THE_TEXTVIEW_ID);
    

    now set the textview properties..

    text.setTypeface(null, Typeface.BOLD);  //-- for only bold the text
    text.setTypeface(null, Typeface.BOLD_ITALIC);  //-- for  bold & italic the text
    text.setTypeface(null, Typeface.ITALIC);  // -- for  italic the text

    Programmatically:

    You can do programmatically using setTypeface():

    textView.setTypeface(null, Typeface.NORMAL);      // for Normal Text
    textView.setTypeface(null, Typeface.BOLD);        // for Bold only
    textView.setTypeface(null, Typeface.ITALIC);      // for Italic
    textView.setTypeface(null, Typeface.BOLD_ITALIC); // for Bold and Italic
    

    XML:

    You can set Directly in XML file in <TextView /> like:

    android:textStyle="normal"
    android:textStyle="normal|bold"
    android:textStyle="normal|italic"
    android:textStyle="bold"
    android:textStyle="bold|italic"

    Standard way to do this is to use the custom styles. Ex-

    In styles.xml add the following.

    <resources xmlns:android="http://schemas.android.com/apk/res/android">
    <style name="MyApp.TextAppearance.LoginText">
        <item name="android:textStyle">bold|italic</item>
    </style>
    

    Apply this style to your TextView as follows.

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        style="@style/MyApp.TextAppearance.LoginText" />

    Since I want to use a custom font only conjunction of several answers works for me. Obviously settings in my layout.xml like android:textStlyle="italic" was ignored by AOS. So finally I had to do as follows: in strings.xml the target string was declared as:

    <string name="txt_sign"><i>The information blah blah ...</i></string>
    

    then additionally in code:

    TextView textSign = (TextView) findViewById(R.id.txt_sign);
    FontHelper.setSomeCustomFont(textSign);
    textSign.setTypeface(textSign.getTypeface(), Typeface.ITALIC);
    

    I didn't try the Spannable option (which I assume MUST work) but

    textSign.setText(Html.fromHtml(getString(R.string.txt_sign))) 
    

    had no effect. Also if I remove the italic tag from strings.xml leaving the setTypeface() all alone it has no effect either. Tricky Android...

    Try this:

    TextView textview = (TextView)findViewById(R.id.textview_idname);
    textview.setTypeface(null,Typeface.BOLD);

    Programmatically:

    You can do programmatically using setTypeface() method:

    Below is the code for default Typeface

    textView.setTypeface(null, Typeface.NORMAL);      // for Normal Text
    textView.setTypeface(null, Typeface.BOLD);        // for Bold only
    textView.setTypeface(null, Typeface.ITALIC);      // for Italic
    textView.setTypeface(null, Typeface.BOLD_ITALIC); // for Bold and Italic
    

    and if you want to set custom Typeface:

    textView.setTypeface(textView.getTypeface(), Typeface.NORMAL);      // for Normal Text
    textView.setTypeface(textView.getTypeface(), Typeface.BOLD);        // for Bold only
    textView.setTypeface(textView.getTypeface(), Typeface.ITALIC);      // for Italic
    textView.setTypeface(textView.getTypeface(), Typeface.BOLD_ITALIC); // for Bold and Italic
    

    XML:

    You can set directly in XML file in <TextView /> like this:

    android:textStyle="normal"
    android:textStyle="normal|bold"
    android:textStyle="normal|italic"
    android:textStyle="bold"
    android:textStyle="bold|italic"
    

    Or you can set your fav font (from assets). for more info see link

    And as explained here Android Developers String Resources if you need to use parameters in your styled text resource, you have to escape the opening brackets

    <resources>
    <string name="welcome_messages">Hello, %1$s! You have &lt;b>%2$d new messages&lt;/b>.</string>
    </resources>
    

    and call formatHtml(string)

    Resources res = getResources();
    String text = String.format(res.getString(R.string.welcome_messages), username, mailCount);
    CharSequence styledText = Html.fromHtml(text);

    Best way is to define it in styles.xml

    <style name="common_txt_style_heading" parent="android:style/Widget.TextView">
            <item name="android:textSize">@dimen/common_txtsize_heading</item>
            <item name="android:textColor">@color/color_black</item>
            <item name="android:textStyle">bold|italic</item>
    </style>
    

    And update it in TextView

      <TextView
         android:id="@+id/txt_userprofile"
         style="@style/common_txt_style_heading"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:layout_centerHorizontal="true"
         android:layout_marginTop="@dimen/margin_small"
         android:text="@string/some_heading" />

    android:textStyle="bold"

    AppCompatTextView text =(AppCompatTextView)findViewById(R.layout.appCompatTextView1);
    text.setTypeface(null,Typeface.BOLD);
    

    Use above method to set the typeface programmatically.

    One way you can do is :

    myTextView.setTypeface(null, Typeface.ITALIC);
    myTextView.setTypeface(null, Typeface.BOLD_ITALIC);
    myTextView.setTypeface(null, Typeface.BOLD);
    myTextView.setTypeface(null, Typeface.NORMAL);
    

    Another option if you want to keep the previous typeface and don't want to lose previously applied then:

    myTextView.setTypeface(textView.getTypeface(), Typeface.NORMAL);      
    myTextView.setTypeface(textView.getTypeface(), Typeface.BOLD);        
    myTextView.setTypeface(textView.getTypeface(), Typeface.ITALIC);      
    myTextView.setTypeface(textView.getTypeface(), Typeface.BOLD_ITALIC);

    You can try like this:

    <string name="title"><u><b><i>Your Text</i></b></u></string>

    In my case:

    1 - set text

    2 - set typeface

    holder.title.setText(item.nome);
    holder.title.setTypeface(null, Typeface.BOLD);

    This is the only thing that worked for me on a OnePlus 5T configured with the OnePlus Slate™ font:

    textView.setTypeface(Typeface.create(textView.getTypeface(), useBold ? Typeface.BOLD : Typeface.NORMAL));
    

    Other methods would make it fall back to Roboto when either BOLD or NORMAL.
