Android - set TextView TextStyle programmatically?

Question

Is there a way to set the textStyle attribute of a TextView programmatically? There doesn\'t appear to be a setTextStyle() method.

Answer 1

This worked for me

textview.setTypeface(textview.getTypeface(), Typeface.BOLD);

or

textview.setTypeface(Typeface.DEFAULT_BOLD);

Answer 2

So many way to achieve this task some are below:-

1.

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

2.

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

3.

SpannableString spannablecontent=new SpannableString(o.content.toString());
spannablecontent.setSpan(new StyleSpan(android.graphics.Typeface.BOLD_ITALIC), 
                         0,spannablecontent.length(), 0);
// set Text here
tt.setText(spannablecontent);

4.

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <style name="boldText">
        <item name="android:textStyle">bold|italic</item>
        <item name="android:textColor">#FFFFFF</item>
    </style>

    <style name="normalText">
        <item name="android:textStyle">normal</item>
        <item name="android:textColor">#C0C0C0</item>
    </style>

</resources>

 tv.setTextAppearance(getApplicationContext(), R.style.boldText);

or if u want through xml

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

Answer 3

textview.setTypeface(Typeface.DEFAULT_BOLD);

setTypeface is the Attribute textStyle.

As Shankar V added, to preserve the previously set typeface attributes you can use:

textview.setTypeface(textview.getTypeface(), Typeface.BOLD);

Answer 4

As mentioned here, this feature is not currently supported.

Search for setTextAppearance or also setTextTypeface. There is similar question on stackoverflow: How to change a TextView's style at runtime
