I want to apply custom font in whole application widget(ActionBar,Navigation Drawer,Tabs,Toolbar,Toast) text without using any third party library so how can I achieve this?
any way to got this.
Custom font in android application Widget(
Actionbar,Drawer,etc.) Text without any third party .
Use .ttf file of your selected font. copy it into assets folder. Provide path of that font file to the TypeFace like this.
TypeFace mTypeFace = Typeface.createFromAsset(getAssets(), "expressway.ttf");
TextView txt = (TextView) findViewById(R.id.text);
txt.setTypeface(mTypeFace);
Till now,
There is no way to apply global font to all the TextView throughout whole App using Android APIs, though Android O introduces a new feature, Fonts in XML, which lets you use fonts as resources.

If we talk about libraries, there is most famous that can do the trick for you. Check this out - Calligraphy. Github page have better explanation about how you use and how things works behind.
you can use Attribute set for this: MyTextView.class
public class MyTextView extends TextView {
public MyTextView(Context context) {
super(context);
init(context, null);
}
public MyTextView(Context context, AttributeSet attrs) {
super(context, attrs);
init(context, attrs);
}
public MyTextView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
init(context, attrs);
}
private void init(Context c, AttributeSet arts){
try {
if (!isInEditMode()) {
if (arts != null) {
TypedArray array = getContext().obtainStyledAttributes(arts, R.styleable.MyViewStyle);
String fontName = array.getString(R.styleable.MyViewStyle_font_name);
if (fontName != null) {
Typeface typeface = Typeface.createFromAsset(getContext().getAssets(), "fonts/" + fontName);
setTypeface(typeface);
}
array.recycle();
}
}
}catch (Exception e){
e.printStackTrace();
}
}
}
attr.xml
<declare-styleable name="MyViewStyle">
<attr name="font_name" format="string" />
</declare-styleable>
use this text view in your xml:
<com.packg.widgets.MyTextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/description_label"
app:font_name="your font name" />
Android also has support for fonts check this link: fonts
FontUtils.java
public class FontUtils {
private static Map<String, Typeface> TYPEFACE = new HashMap<String, Typeface>();
public static SpannableString actionBar(Activity mActivity, String title) {
SpannableString s = new SpannableString(title);
s.setSpan(new TypefaceSpan(mActivity, "simple.ttf"), 0, s.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
return s;
}
public static void overrideFonts(final Activity mActivity) {
mActivity.getLayoutInflater().setFactory(new LayoutInflater.Factory() {
@Override
public View onCreateView(String name, Context context, AttributeSet attrs) {
View v = FontUtils.tryInflate(name, context, attrs);
if (v instanceof TextView) {
FontUtils.setTypeFace((TextView) v, mActivity);
}
return v;
}
});
}
public static Typeface getFonts(Context context, String name) {
Typeface typeface = TYPEFACE.get(name);
if (typeface == null) {
typeface = Typeface.createFromAsset(context.getAssets(), "fonts/"+ name);
TYPEFACE.put(name, typeface);
}
return typeface;
}
public static View tryInflate(String name, Context context, AttributeSet attrs) {
LayoutInflater li = LayoutInflater.from(context);
View v = null;
try {
v = li.createView(name, null, attrs);
} catch (Exception e) {
try {
v = li.createView("android.widget." + name, null, attrs);
} catch (Exception e1) {
}
}
return v;
}
public static void setTypeFace(TextView tv, Context mContext) {
tv.setTypeface(FontUtils.getFonts(mContext, "simple.ttf"));
}
}
TypefaceSpan.java
public class TypefaceSpan extends MetricAffectingSpan {
private static LruCache<String, Typeface> sTypefaceCache =
new LruCache<String, Typeface>(12);
private Typeface mTypeface;
public TypefaceSpan(Context context, String typefaceName) {
mTypeface = sTypefaceCache.get(typefaceName);
if (mTypeface == null) {
mTypeface = Typeface.createFromAsset(context.getApplicationContext()
.getAssets(), String.format("fonts/%s", typefaceName));
sTypefaceCache.put(typefaceName, mTypeface);
}
}
@Override
public void updateMeasureState(TextPaint p) {
p.setTypeface(mTypeface);
p.setFlags(p.getFlags() | Paint.SUBPIXEL_TEXT_FLAG);
}
@Override
public void updateDrawState(TextPaint tp) {
tp.setTypeface(mTypeface);
tp.setFlags(tp.getFlags() | Paint.SUBPIXEL_TEXT_FLAG);
}
}
inside activity
@Override
protected void onCreate(Bundle savedInstanceState) {
FontUtils.overrideFonts(YourActivity.this);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//toolbar
getSupportActionBar().setTitle(FontUtils.actionBar(this, getResources().getString(R.string.app_name)));
}
Create font resource XML :
<?xml version="1.0" encoding="utf-8"?>
<font-family xmlns:android="http://schemas.android.com/apk/res/android">
<font
android:fontStyle="normal"
android:fontWeight="400"
android:font="@font/lobster_regular" />
<font
android:fontStyle="italic"
android:fontWeight="400"
android:font="@font/lobster_italic" />
</font-family>
Adding fonts to a TextView :
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:fontFamily="@font/lobster"/>
Android 8.0 (API level 26) introduces a new feature, Fonts in XML, which lets you use fonts as resources.
Create font resource XML :
<?xml version="1.0" encoding="utf-8"?>
<font-family xmlns:android="http://schemas.android.com/apk/res/android">
<font
android:fontStyle="normal"
android:fontWeight="400"
android:font="@font/lobster_regular" />
<font
android:fontStyle="italic"
android:fontWeight="400"
android:font="@font/lobster_italic" />
</font-family>
Adding fonts to a TextView :
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:fontFamily="@font/lobster"/>
Using fonts programmatically :
Typeface typeface = getResources().getFont(R.font.myfont);
textView.setTypeface(typeface);
