Font awesome text is not solid in Android

I am trying to show hand pointer icon which is https://fontawesome.com/icons/hand-pointer?style=regular I want to show it solidly(white background) like this one https://fontawesome.com/icons/hand-pointer?style=solid .
But here I have a problem that both of them has the same unicode which is f25a.
//This is the FontAwesomeTextView I Created
FontAwesomeTextView fingerPointer = new FontAwesomeTextView(MyApplication.getStaticContext());
fingerPointer.setText(MyApplication.getStaticContext().getString(R.string.finger_pointer));
fingerPointer.setTextColor(ContextCompat.getColor(MyApplication.getStaticContext(), R.color.colorWhite));
fingerPointer.setShadowLayer(2,2,2,R.color.colorOrange);
fingerPointer.setTextSize(30f);
fingerPointer.setVisibility(View.GONE);
this.fingerPointer = fingerPointer;
//This is the hand pointer text that I am using
<string name="finger_pointer" translatable="false"></string>
As you can see icon i send in link has the same unicode in string.xml.
This is my FontAwesomeTextView which is pretty simple class that loads fontawesome typeface and set it.
public class FontAwesomeTextView extends AppCompatTextView {
public FontAwesomeTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
public FontAwesomeTextView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public FontAwesomeTextView(Context context) {
super(context);
init();
}
private void init() {
Typeface typeface = FontCache.get(FontCache.FONT_AWESOME,getContext());
setTypeface(typeface);
}
}

How do I change a Button font after it's added to a ViewGroup?

Given a Button created at runtime:
Button button = Button(context)
The way to set a custom typeface is:
button.setTypeface(myTypeface)
However I find it only works before I add it to a ViewGroup and not after.
I've also tried:
button.setTypeface(myTypeface, myStyle)
but it didn't work either. I need to change my Button font dynamically. I've tried invalidate() and requestLayout() but the font never changes.

Solution:- you can subclass the Button class with your custom font and use it instead of button.
public class MyButton extends AppCompatButton {
public MyButton(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
public MyButton(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public MyButton(Context context) {
super(context);
init();
}
private void init() {
if (!isInEditMode()) {
Typeface tf = Typeface.createFromAsset(getContext().getAssets(), "font.ttf");
setTypeface(tf);
}
}
}

retrieve custom char with charcode android

I'm using a custom font with characters like star, sun, etc.
I know their charcode into this font.
I set the TextView font with the following code:
public class MyTextView extends TextView {
public MyTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
public MyTextView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public MyTextView(Context context) {
super(context);
init();
}
public void init() {
Typeface tf = Typeface.createFromAsset(getContext().getAssets(), "font/myFont.ttf");
setTypeface(tf ,1);
}}
is there a way, since I know their charcode, to use those specific characters directly in strings.xml and programmatically?

You can reference characters by their 4 digit hexadecimal code in java :
String someString = "\u2776"
Or in resources :
<string name="some_string_name">\u2776</string>
(2776 is the code for ❶ in the default font)

how to specify the font file in the settings instead of code?

I'm trying to decorate my application fonts. I get to do it from code. but do not know how to do it in the settings. in the code I do so
public class Fonts {
public static Typeface getHeaderFont(Context context){
return Typeface.createFromAsset(context.getAssets(), "header_levelI.ttf");
}
public static Typeface getSubHeaderFont(Context context){
return Typeface.createFromAsset(context.getAssets(), "header_levelII.ttf");
}
}
and
Typeface type= Fonts.getHeaderFont(getActivity());
TextView header = (TextView) v.findViewById(R.id.cassaName);
header.setTypeface(type);
settings android studio only standard fonts. How do I specify fonts in the file not to write extra code?

Create Custom TextView with your custom font.
Note: It's important that you place required font files in the assets/fonts directory.
public class CustomTextView extends TextView {
public CustomTextView(Context context) {
super(context);
setFont();
}
public CustomTextView(Context context, AttributeSet attrs) {
super(context, attrs);
setFont();
}
public CustomTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
setFont();
}
private void setFont() {
Typeface font = Typeface.createFromAsset(getContext().getAssets(),"fonts/ss-symbolicons-line.ttf");
setTypeface(font, Typeface.NORMAL);
}
}

Set textcolor and other attribute in textview extends

How can i set text color and text size in the class below
public class MyTextView extends TextView {
public MyTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
public MyTextView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public MyTextView(Context context) {
super(context);
init();
}
public void init() {
Typeface tf = Typeface.createFromAsset(getContext().getAssets(), "font/chiller.ttf");
setTypeface(tf ,1);
}
}

In your init use setTextColor and setTextSize
public void init() {
Typeface tf = Typeface.createFromAsset(getContext().getAssets(), "font/chiller.ttf");
setTypeface(tf ,1);
this.setTextColor(Color.RED);
this.setTextSize(20f);
}
