Change title font of Alert Dialog box

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(); 

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);

Do like this :

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")); 

Have your font.ttf file in the assets folder and use it like above

You have to inflate or customize and create a style and apply to AlertDialog

Heres how you inflate a layout and apply it to AlertDialog

LayoutInflater li = LayoutInflater.from(ctx); View view = li.inflate(R.layout.formatted_dialog, null); AlertDialog.Builder builder = new AlertDialog.Builder(ctx); builder.setTitle("Formatted"); builder.setView(view); 

define all the formatting and styles required in the layout you specified.

You can access specific textview defined in the layout using inflated View i.e.

LayoutInflater li = LayoutInflater.from(ctx); View view = li.inflate(R.layout.formatted_dialog, null); TextView label=(TextView)view.findViewById(R.id.i_am_from_formatted_layout_lable); 

Sample layout saved as res/layout/link.xml:

In your onCreate() or where or whenever you want to call AlertDialog

LayoutInflater li = LayoutInflater.from(this); View view = li.inflate(R.layout.link, null); AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setTitle("Formatted"); builder.setView(view).create().show(); TextView text=(TextView) findViewById(R.id.text); 

replace this with context object if you are calling from some other method.

Instead of setting the text of the alertdialog, you should set a custom view form your layouts. And before you do so, modify your view's font. try this example

TextView content = new TextView(this); content.setText("on another font"); content.setTypeface(Typeface.SANS_SERIF); 

//Use the first example, if your using a xml generated view

 AlertDialog.Builder myalert = new AlertDialog.Builder(this); myalert.setTitle("Your title"); myalert.setView(content); myalert.setNeutralButton("Close dialog", null); myalert.setCancelable(true); myalert.show(); 

code for xml...replace your font in the xml

<TextView android:id="@+id/yourid" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="8dp" android:text="your content" /> 

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

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) 

You can change appearence of AlertDialog by following this block of code:

AlertDialog dialog = new AlertDialog.Builder(this).setMessage("Message").show(); TextView textView = (TextView) dialog.findViewById(android.R.id.message); textView.setTextSize(10);//to change font size //to change font family Typeface face = Typeface.createFromAsset(getAssets(),"font/fontFileName.ttf"); textView.setTypeface(face); 

Put font file in assets folder. In my case I created a subdirectory called font.

And you can also check for this Question which have an accepted answer.

You can add this

TextView textViewt = (TextView) alertDialog.findViewById(android.R.id.title); textViewt.setTypeface(your font typeface); 

after the line

alertDialog.show(); 

There is an easy way to set a new custom view to dialog's title. We can define every custom view such as TextView and add it some custom properties and at last set it to dialog's title, such as below:

 AlertDialog.Builder builder = new AlertDialog.Builder(OrderItemsActivity.this); TextView title_of_dialog = new TextView(getApplicationContext()); title_of_dialog.setHeight(50); title_of_dialog.setBackgroundColor(Color.RED); title_of_dialog.setText("Custom title"); title_of_dialog.setTextSize(TypedValue.COMPLEX_UNIT_SP, 15); title_of_dialog.setTextColor(Color.WHITE); title_of_dialog.setGravity(Gravity.CENTER); builder.setCustomTitle(title_of_dialog); builder.create().show(); 

Here, I define a dynamic TextView and set some properties to it. Finally, I set it to dialog's title using "setCustomTitle()" function.

Use this method from support library 26.

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

Try setting theme for the dialog. Change the typeface attribute like this :

<style name="CustomDialog" parent="android:Theme.Dialog"> <item name="android:typeface">serif</item> </style> 

Though this changes Fonts of all the textviews within the dialog. so make sure TextViews are set to proper typeface

TextView tv_message = new TextView(this); Typeface typeface = Typeface.createFromAsset( getAssets(), "fonts/OpenSans-Semibold.ttf" ); // Set the text view layout parameters tv_message.setLayoutParams( new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT) ); // Set message text color tv_message.setTextColor(Color.RED); // Set message gravity/text align tv_message.setGravity(Gravity.START); // Set message text size tv_message.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 16); // Set message custom font tv_message.setTypeface(typeface); // Set message background color tv_message.setBackgroundColor(Color.YELLOW); // Set message text padding tv_message.setPadding(15, 25, 15, 15); tv_message.setText("Are you sure?"); tv_message.setTextColor(Color.BLACK);
