Change title font of Alert Dialog box

Question

I want to change the font of the title of Alert Dialog box.

Can anybody tell how can I do it?

Answer 1

Include this layout:

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

  <TextView
   android:id="@+id/text"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:text="Hello_World"
   android:textColorLink="#FF00FF"
  />

</LinearLayout>

Then use it inside Ur Activity

Dialog dialog = new Dialog(ActivityName.this);
dialog.setContentView(R.layout.dialog_name);
dialog.setCancelable(true);
dialog.findViewById(R.id.text).setTypeface(Typeface.createFromAsset(getAssets(), "font.ttf"));

Another Way and this

Answer 2

You can try Spannable as well.

            SpannableString s = new SpannableString("My App");
            s.setSpan(new TypefaceSpan(this, "font.otf"), 0, s.length(),
                    Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
            s.setSpan(new RelativeSizeSpan(1.3f), 0,s.length(), 0);
            builder.setTitle(s)

Answer 3

Use this method from support library 26.

ResourcesCompat.getFont(context, R.font.<YOUR_FONT>);

Answer 4

Just use the following line to get an identifier to the dialog's title:

int dialogTitle = mCtnx.getResources().getIdentifier( "alertTitle", "id", "android" );

use this one for android.support.v7.app.AlertDialog

TextView title= (TextView)alertDialog.findViewById(R.id.alertTitle);

Answer 5

I found a simple solution..

At first I was setting the title of my alert box by

builder.setTitle("My Title");

So I was not able to change the font of it..

Then what worked for me is..

I created a simple TextView :

TextView tv2;

And set all properties of TextView which I wanted...

And then I replaced my

builder.setTitle("My Title");

line with

builder.setCustomTitle(tv2);

and now I can change Title Color, Font Etc By Changing tv2's Properties..

Answer 6

No answers provide a way to change the title typeface of an AlertDialog. Here is what I have done:

Create the below class:

public static class TypefaceSpan extends MetricAffectingSpan {

  private final Typeface typeface;

  public TypefaceSpan(Typeface typeface) {
    this.typeface = typeface;
  }

  @Override public void updateDrawState(TextPaint tp) {
    tp.setTypeface(typeface);
    tp.setFlags(tp.getFlags() | Paint.SUBPIXEL_TEXT_FLAG);
  }

  @Override public void updateMeasureState(TextPaint p) {
    p.setTypeface(typeface);
    p.setFlags(p.getFlags() | Paint.SUBPIXEL_TEXT_FLAG);
  }

}

Add the following utility method:

/**
 * <p>Return spannable string with applied typeface in certain style</p>
 *
 * http://stackoverflow.com/questions/8607707/how-to-set-a-custom-font-in-the-actionbar-title
 *
 * @param typeface
 *     The typeface to set to the {@link SpannableString}
 * @param string
 *     the string to place in the span
 * @return SpannableString that can be used in TextView.setText() method
 */
public static SpannableString typeface(Typeface typeface, CharSequence string) {
  SpannableString s = new SpannableString(string);
  s.setSpan(new TypefaceSpan(typeface), 0, s.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
  return s;
}

Finally, set the typeface when creating your AlertDialog:

Typeface typeface = Typeface.createFromAsset(getActivity().getAssets(), "fonts/your_font.ttf");
new AlertDialog.Builder(getActivity())
    .setTitle(FontUtils.typeface(typeface, "The title"))
    /* .. */
    .create();
