How to set TextView
style (bold or italic) within Java and without using the XML layout?
In other words, I need to write android:textStyle
with Java.
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
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"
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).
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
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
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
Use textView.setTypeface(Typeface tf, int style);
to set style property of the TextView
. See the developer documentation for more info.
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" />
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);
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$s! You have <b>%2$d new messages</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);
The easiest way you can do based on the style selection criteria is:
String pre = "", post = "";
if(isBold){
pre += "<b>"; post += "</b>";
}
if(isItalic){
pre += "<i>"; post += "</i>";
}
if(isUnderline){
pre += "<u>"; post += "</u>";
}
textView.setText(Html.fromHtml(pre + editText.getText().toString()+ post));
// you can also use it with EidtText
editText.setText(Html.fromHtml(pre + editText.getText().toString()+ post));
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...
You can set the different typeface using the example given below -
textView.setTypeface(textView.getTypeface(), Typeface.BOLD);
textView.setTypeface(textView.getTypeface(), Typeface.ITALIC);
textView.setTypeface(textView.getTypeface(), Typeface.BOLD_ITALIC);
Or if you want to set a different font and its typeface . Add it to asset or raw folder and then use it like
Typeface face= Typeface.createFromAsset(getAssets(), "font/font.ttf");
tv1.setTypeface(face);
Typeface face1= Typeface.createFromAsset(getAssets(), "font/font1.ttf");
tv2.setTypeface(face1);
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" />
