In android How to applying font for whole application?

I want to apply some font say Times New Roman to only my application. Not to the whole system and not to specific view. As far I know

to apply font to specific view we store font file in asset folder and get into the application 开发者_Go百科as follow.

1]  Typeface  mFace = Typeface.createFromAsset(getContext().getAssets(),
                                     "fonts/samplefont.ttf");
    textView.setTypeface(mFace);


2] To apply font to whole application I can replace the DroidSans.ttf file with my font file.

I can use first way to apply font to my application but It won't be a good solution because I need to modify everywhere and I don't want to do that if there is any better way is available.

I made a custom textview widget and in the constructors made a call to this code:

public static void SetCustomFont (TextView t, String fontName, Context c) {
        Typeface tf = Typeface.createFromAsset(c.getAssets(),
                fontName);
        t.setTypeface(tf);
}

I'm using the same font over the whole application so I put the fontName in the constuctor and then did a global Find/Replace for TextView

Android does not provide much in the way of support for applying fonts across the whole app (see this issue). You have 4 options to set the font for the entire app:

• Option1: Apply reflection to change the system font
• Option2: Create and subclass custom View classes for each View that needs a custom font
• Option3: Implement a View Crawler which traverses the view hierarchy for the current screen
• Option4: Use a 3rd party library.

Details of these options can be found here.

Check this to define fonts styles. In addition, you can refer to this style from your manifest file at the app level

<application
    android:theme="@style/Theme1">
