Accessing custom attribute defined in a style - android

The problem I am trying to solve is to have a custom font in an android application. I have followed a few tutorials and stack overflow questions but I can't seem to get exactly what I want.
I have a custom attribute defined in attrs.xml:
<resources>
<declare-styleable name="CustomTextView">
<attr name="customTypeface" format="string"/>
</declare-styleable>
and that customTypeface defined in the style:
<style name="posTheme" parent="#android:style/Theme.Holo.Light">
<item name="android:textViewStyle">#style/posThemeTextViewStyle</item>
</style>
<style name="posThemeTextViewStyle" parent="android:Widget.TextView">
<item name="android:textSize">50sp</item>
<item name="customTypeface">Fonts/MuseoSans_100.otf</item>
</style>
in an activity the form looks looks like:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:custom="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:id="#+id/tv1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="LOL OL U MAD BRO!"
/>
<myApplication.Controls.CustomTextView
android:id="#+id/tv2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="LOL OL U MAD BRO!"
></myApplication.Controls.iQTextView>
</LinearLayout>
and when I go about trying to get the attribute:
public CustomTextView(Context context, IAttributeSet attrs, int defStyle)
: base(context, attrs, defStyle)
{
var a = context.ObtainStyledAttributes(attrs,
Resource.Styleable.CustomTextView);
var customFont = a.GetString(Resource.Styleable.CustomTextView_customTypeface);
SetCustomFont(customFont);
a.Recycle();
}
customFont is null, unless I implicitly define custom:customTypeface="" in the activity but I don't want to have to define the font for every single instance of the control.
What am I missing?

Shouldn't those two lines :
var a = context.ObtainStyledAttributes(attrs,
Resource.Styleable.CustomTextView);
var customFont = a.GetString(Resource.Styleable.CustomTextView_customTypeface);
be :
var a = context.ObtainStyledAttributes(attrs,
R.Styleable.CustomTextView);
var customFont = a.GetString(R.Styleable.CustomTextView_customTypeface);

Not able to set color through custom TextView android

Hi I had requirement to implement a custom textview to be used across all modules in my app. I am facing issues while setting color through custom textview. The color is not set through custom TextView Please find my implementation and help me in resolving this issue
attrs.xml :
<?xml version="1.0" encoding="utf-8"?>
<resources>
<declare-styleable name="CustomFontTextView">
<attr name="textColor"></attr>
</declare-styleable>
<attr name="textColor" format="enum">
<enum name="Regular_Color" value="1"/>
</attr>
</resources>

CustomTextView:
#RequiresApi(Build.VERSION_CODES.M)
class CustomFontTextView #JvmOverloads constructor(
context: Context,
attrs: AttributeSet? = null,
defStyle: Int = 0,
defStyleRes: Int = 0
) : AppCompatTextView(context, attrs, defStyle) {
var customFont: String? = null
init {
attrs?.let {
val a = context.obtainStyledAttributes(
attrs,
R.styleable.CustomFontTextView
)
setColor(a,context, attrs);
}
}
#SuppressLint("ResourceType")
#RequiresApi(Build.VERSION_CODES.M)
private fun setColor(typedArray: TypedArray, context: Context,
attrs: AttributeSet){
val cf = typedArray.getInteger(R.styleable.CustomFontTextView_textColor, 0)
var textViewColor = 0
textViewColor = when(cf){
1 -> R.color.colorNormal
else->R.string.Regular_Color
}
this.setTextColor(textViewColor)
invalidate()
requestLayout()
}
}
When the app is run the color is not set actually its supposed to set green color.
My layout is below:

How to change the font family of SwitchCompat?

I've noticed that the SwitchCompat's font does not seem to change with what I've set in the fontFamily field. I've also tried using styles with custom fontFamily (which works on TextViews) and even the switchTextAppearance field. It does apply on the preview (I know the preview is not really accurate) but not when I tried running it on my test device.
Here's my SwitchCompat:
<android.support.v7.widget.SwitchCompat
style="#style/MyStyle.Body"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fontFamily="#font/my_font_family"
android:text="Enable"
app:switchTextAppearance="#style/MyStyle.Body"/>
and here's my style:
<style name="MyStyle.Body" parent="Base.TextAppearance.AppCompat.Body1">
<item name="android:textSize">14sp</item>
<item name="android:fontFamily">#font/my_font_family</item>
<item name="android:textColor">#color/color_primary_text</item>
</style>
As you can see, I only really want to change it's font
EDIT
I've changed my style to this
<style name="MyStyle.Switch" parent="Widget.AppCompat.CompoundButton.Switch">
<item name="android:textSize">14sp</item>
<item name="android:textColor">#color/color_primary_text</item>
<item name="android:fontFamily">#font/my_font_family</item>
<item name="fontFamily">#font/my_font_family</item>
</style>
still doesn't work though
XML settings is not working, therefore I use following code:
someSwitch.setTypeface(ResourcesCompat.getFont(context, R.font.roboto));
Try
parent="Base.TextAppearance.AppCompat.Body1"
replace into this
parent="TextAppearance.AppCompat.Widget.Switch"
Try below
public class CustomSwitchCompact extends SwitchCompat {
public CustomSwitchCompact(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
public CustomSwitchCompact(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public CustomSwitchCompact(Context context) {
super(context);
init();
}
private void init() {
if (!isInEditMode()) {
Typeface myFonts = Typeface.createFromAsset(getContext().getAssets(),
"fonts/Roboto_Bold.ttf");
setTypeface(myFonts);
}
}
}
XML file
<com.test.CustomSwitchCompact
android:id="#+id/switch_compat"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:checked="false"
android:padding="20dp"
android:text="SwitchCompat"
android:textOff="OFF"
android:textOn="ON"
app:showText="true" />
Another way to achieve SwitchCompact with custom font
<android.support.v7.widget.SwitchCompat
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/adamSwitch"
android:textColor="#color/top_color"
android:textAppearance="#color/top_color"
android:gravity="center"
app:showText="true"
android:fontFamily="#font/my_font_family"
app:theme="#style/Custom.Widget.SwitchCompat"
app:switchPadding="5dp"
/>
in style.xml
<style name="Custom.Widget.SwitchCompat" parent="Widget.AppCompat.CompoundButton.Switch" >
<item name="android:textColorPrimary">#color/blue</item>
<item name="android:textSize">14sp</item>
<item name="android:fontFamily">#font/my_font_family</item>
<item name="android:textColor">#color/color_primary_text</item>
</style>
The only thing that works for me is setSwitchTypeface, not setTypeface:
my_switch.setSwitchTypeface(ResourcesCompat.getFont(context, R.font.my_font))
I've used android:textAppearance instead of android:switchTextAppearance and custom font works now. Also my switch style have Widget.AppCompat.CompoundButton.Switch as parent

Android: How to custom-declare XML namespace in styles.xml?

I'm trying to put the custom XML namespace in the styles.xml and inherit it in the layout. I don't know how to declare the custom XML namespace in the styles.xml as I do in layout xml (e.g. xmlns:app="http://schemas.android.com/tools").
How do I use custom XML namespace in the styles.xml?
What I have:
The font asset, ReallyCoolFont.ttf is saved in the asset/fonts.
my_layout.xml:
<TextView
<!-- more attributes here -->
app:customFont="fonts/ReallyCoolFont.ttf"
<!-- more attributes here -->
</TextView>
styles.xml:
<style name="CoolTextView">
<!-- more items here -->
<!-- more items here -->
</style>
What I'd like to have:
my_layout.xml:
<TextView
<!-- more attributes here -->
style="#style/CoolTextView
<!-- more attributes here -->
</TextView>
styles.xml:
<style name="CoolTextView">
<!-- more items here -->
<item name="app:customFont">ReallyCoolFont.ttf</item>
<!-- more items here -->
</style>
Error I get:
Error:(1403, 21) No resource found that matches the given name: attr 'app:customFont'.
You need to define an attribute for your fonts in attr.xml file in res folder:
<attr name="myfonts" format="string" />
And you need to define custom style for your TextView and here we use our defined attribute(myfonts):
<declare-styleable name="MyCustomStyle">
<attr name="myfonts" />
</declare-styleable>
Then styles can be declared:
<style name="CoolTextView">
<item name="myfonts">ReallyCoolFont.ttf</item>
</style>
summary of what you have so far:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<attr name="myfonts" format="string">
</attr>
<declare-styleable name="MyCustomStyle">
<attr name="myfonts" />
</declare-styleable>
<style name="CoolTextView">
<item name="myfonts">ReallyCoolFont.ttf</item>
</style>
</resources>
4)Now your layout would be:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<com.example.MyCustomTextView
android:id="#+id/result"
style="#style/CoolTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="HELLO WORLD!"
android:textSize="24dp"
android:gravity="center" >
</com.example.MyCustomTextView>
</RelativeLayout>
5)and your MyCustomTextView is:
public class MyCustomTextView extends TextView {
private static final String TAG = "TextView";
public MyCustomTextView(Context context) {
super(context);
}
public MyCustomTextView(Context context, AttributeSet attrs) {
super(context, attrs);
settingFont(context, attrs);
}
public MyCustomTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
settingFont(context, attrs);
}
private void settingFont(Context ctx, AttributeSet attrs) {
TypedArray a = ctx.obtainStyledAttributes(attrs, R.styleable.MyCustomStyle);
String customFont = a.getString(R.styleable.MyCustomStyle_myfonts);
Typeface tf = null;
try {
tf = Typeface.createFromAsset(ctx.getAssets(), customFont);
} catch (Exception e) {
Log.e(TAG,e.getMessage());
a.recycle();
return;
}
setTypeface(tf);
a.recycle();
}
}
I assumed you put the font in asset not in asset/fonts directory.
also I highly recommend read this.
You don't need to add any prefix to reference your custom attributes in the style resource files. Doing it like this will work just fine:
<style name="CoolTextView">
<item name="customFont">ReallyCoolFont.ttf</item>
</style>
The answer is to NOT specify the namespace in the style.
<?xml version="1.0" encoding="utf-8" ?>
<resources xmlns:custom="http://schemas.android.com/apk/res/com.custom.project">
<style name="CustomStyle">
<item name="android:layout_width">wrap_content</item>
<item name="android:layout_height">wrap_content</item>
<item name="customAttr">value</item> <!-- tee hee -->
</style>
</resources>
You don't need any prefixes, it will work without them. This is code from one of my projects, which works just fine
<style name="defaultTriangle">
<item name="triangleColor">#FF33B5E5</item>
<item name="triangleStrokeColor">#android:color/black</item>
<item name="triangleStrokeWidth">3dp</item>
</style>
<si.kseneman.views.Triangle
style="#style/defaultTriangle"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1"
android:padding="10dp"
android:rotation="0"
/>
I've done next for custom font
CustomTextView
public class KlavikaTextView extends TextView {
private final static int KLAVIKA_BOLD = 0;
private final static int KLAVIKA_BOLD_ITALIC = 1;
private final static int KLAVIKA_LIGHT = 2;
private final static int KLAVIKA_LIGHT_ITALIC = 3;
private final static int KLAVIKA_MEDIUM = 4;
private final static int KLAVIKA_MEDIUM_ITALIC = 5;
private final static int KLAVIKA_REGULAR = 6;
private final static int KLAVIKA_REGULAR_ITALIC = 7;
public KlavikaTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
parseAttributes(context, attrs);
}
public KlavikaTextView(Context context, AttributeSet attrs) {
super(context, attrs);
parseAttributes(context, attrs);
}
public KlavikaTextView(Context context) {
super(context);
}
private void parseAttributes(Context context, AttributeSet attrs) {
TypedArray values = context.obtainStyledAttributes(attrs, R.styleable.KlavikaTextView);
// The value 0 is a default, but shouldn't ever be used since the attr is an enum
int typeface = values.getInt(R.styleable.KlavikaTextView_typeface, KLAVIKA_REGULAR);
// You can instantiate your typeface anywhere, I would suggest as a
// singleton somewhere to avoid unnecessary copies
switch (typeface) {
case KLAVIKA_BOLD:
setTypeface(App.klavikaBold);
break;
case KLAVIKA_BOLD_ITALIC:
setTypeface(App.klavikaBoldItalic);
break;
case KLAVIKA_LIGHT:
setTypeface(App.klavikaLight);
break;
case KLAVIKA_LIGHT_ITALIC:
setTypeface(App.klavikaLightItalic);
break;
case KLAVIKA_MEDIUM:
setTypeface(App.klavikaMedium);
break;
case KLAVIKA_MEDIUM_ITALIC:
setTypeface(App.klavikaMediumItalic);
break;
case KLAVIKA_REGULAR_ITALIC:
setTypeface(App.klavikaRegularItalic);
break;
case KLAVIKA_REGULAR:
default:
setTypeface(App.klavikaRegular);
break;
}
}}
Then in values I've created attr.xml
<!-- Define the values for the attribute -->
<attr name="typeface" format="enum">
<enum name="klavika_bold" value="0" />
<enum name="klavika_bold_italic" value="1" />
<enum name="klavika_light" value="2" />
<enum name="klavika_light_italic" value="3" />
<enum name="klavika_medium" value="4" />
<enum name="klavika_medium_italic" value="5" />
<enum name="klavika_regular" value="6" />
<enum name="klavika_regular_italic" value="7" />
</attr>
<!--
Tell Android that the class "KlavikaTextView" can be styled,
and which attributes it supports-->
<declare-styleable name="KlavikaTextView">
<attr name="typeface" />
</declare-styleable>
Next created the style
<style name="TextView.Example">
<item name="typeface">klavika_bold</item>
</style>
This style you can use for your xml Layouts
style="#style/TextView.Example"
<?xml version="1.0" encoding="utf-8"?>
<resources
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:custom="http://schemas.android.com/apk/res/com.my.project">
<style name="my_style"> <item name="custom:tag">some_value</item> </style>
</resources>
you are trying to apply XML namespacing to an attribute value, which won't work. In this case, you should specify the package name directly, like this:
<style name="my_style"> <item name="com.my.project:tag">some_value</item> </style>
Fast solution via code!
String pathFont = "fonts/ReallyCoolFont.ttf";
TextView text = (TextView) findViewById(R.id.TextView1);
Typeface fontFace = Typeface.createFromAsset( getAssets(), pathFont );
text.setTypeface( fontFace );
Third-party libraries , solve the problem, in XML!

My suggestion
You will have other needs, and for each component
you will have to customize a class.
Another problem you have other layouts and N TextView components
for maintenance you will have a lot of work .
I use this method in projects in the OnCreate of my activity
if I need to change the font I have to do this
only in the OnCreate method of each activity .
private static final String FONT = "ReallyCoolFont.ttf";
public static void allTextView(final Context context, final View root) {
String fontPath = FONT;
try {
if (root instanceof ViewGroup) {
ViewGroup viewGroup = (ViewGroup) root;
int childCount = viewGroup.getChildCount();
for (int i = 0; i < childCount; i++)
allTextView(context, viewGroup.getChildAt(i) );
} else if (root instanceof TextView)
((TextView) root).setTypeface(Typeface.createFromAsset(context.getAssets(), fontPath));
} catch (Exception e) {
e.printStackTrace();
}
}
// call in OnCreate Activity
allTextView(this, findViewById(R.layout.main) );
The custom attributes are defined using <declare-styleable> tags; usually the file is called attrs.xml. The namespace declaration will have your app's package name in it.
The whole process is described here: Creating a View Class | Android Developers

Passing style resource id from XML to class not working

I have a custom widget in a library project (Spinnerbutton) that I want to use in an application project.
The custom widget contains a TextView and I want to pass a style to that TextView from my app project.
This is my attrs.xml (in the library project):
<?xml version="1.0" encoding="utf-8"?>
<resources>
<declare-styleable name="Spinnerbutton">
<attr name="myTextAppearence" format="reference" />
</declare-styleable>
</resources>
And the app's layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:custom="http://schemas.android.com/apk/lib/com.example.spinnerbuttonlib"
android:id="#+id/root"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<com.example.spinnerbuttonlib.spinnerbutton.Spinnerbutton
android:id="#+id/sbp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="8dp"
custom:myTextAppearence="#style/SmallTextGray" />
</RelativeLayout>
Here's how I try to read my custom attribute in the Spinnerbutton class:
public Spinnerbutton(Context context, AttributeSet attrs) {
super(context, attrs);
this.context = context;
TypedArray a = context.obtainStyledAttributes(attrs,
R.styleable.Spinnerbutton);
int textStyleId = a.getResourceId(
R.styleable.Spinnerbutton_myTextAppearence, -1);
a.recycle();
}
textStyleId always return -1, so the value is not passed from my layout to the class.
What's wrong here?
The library project has a Customview Spinnerbutton which extends TextView (in you case it may be different. For testing i extended TextView).
Now if i understand correctly this view is used in android project and you need to set the style to that custom view which can be done as below.
Use the style in android library project as the parent style and then customize the style in android project styles.xml. Now set the style to the customview.
package com.example.customviewattributes.p1;
import com.example.customviewattributes.R;
import android.content.Context;
import android.content.res.TypedArray;
import android.util.AttributeSet;
import android.util.Log;
import android.widget.TextView;
public class Spinnerbutton extends TextView{
public Spinnerbutton(Context context) {
this(context, null);
}
public Spinnerbutton(Context context, AttributeSet attrs) {
this(context, attrs, 0);
}
public Spinnerbutton(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
// real work here
TypedArray a = context.getTheme().obtainStyledAttributes(
attrs,
R.styleable.Spinnerbutton,
0, 0
);
try {
int textStyleId = a.getResourceId(
R.styleable.Spinnerbutton_myTextAppearence, -1);
Log.i("................ID is",""+textStyleId);
// to make sure i logged the id
this.setText("hello");
this.setTextAppearance(context,textStyleId);
// set the style to text
} finally {
// release the TypedArray so that it can be reused.
a.recycle();
}
}
}
styles.xml
<resources>
<style name="AppBaseTheme" parent="android:Theme.Light">
<item name="android:textViewStyle">#style/QText</item>
</style>
<style name="AppTheme" parent="AppBaseTheme">
</style>
<style name="QText" parent="#android:style/TextAppearance.Medium">
<item name="android:textSize">20sp</item>
<item name="android:textColor">#color/ccolor</item>
<item name="android:textStyle">bold</item>
<item name="android:typeface">sans</item>
</style>
</resources>
attrs.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<declare-styleable name="Spinnerbutton">
<attr name="myTextAppearence" format="reference" />
</declare-styleable>
</resources>
colors.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="ccolor">#ff3232</color>
</resources>
All the above in library project.
Now in Another Android Project
activity_main.xml
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
>
<com.example.customviewattributes.p1.Spinnerbutton
android:id="#+id/sbp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="8dp"
/>
</RelativeLayout>
In MainActivity.java
setContentView(R.layout.activity_main);
com.example.customviewattributes.p1.Spinnerbutton cv = (Spinnerbutton) findViewById(R.id.sbp);
cv.setTextAppearance(this,R.style.QText1);
cv.setText("hello");
styles.xml
<resources>
<style name="AppBaseTheme" parent="android:Theme.Light">
<item name="android:textViewStyle">#style/QText</item>
</style>
<style name="AppTheme" parent="AppBaseTheme">
</style>
<style name="QText1" parent="#style/QText">
<item name="android:textSize">50sp</item>
<item name="android:textColor">#color/ccolor</item>
<item name="android:textStyle">bold</item>
<item name="android:typeface">sans</item>
</style>
</resources>
colors.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="ccolor">#4F47B7</color>
</resources>
Snap
This is for android project
Now if i run library project as a normal android project
Snap
I think you should try to put the xmlns:custom with your app package name, like this :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:custom="http://schemas.android.com/apk/res/com.example.yourapppackage"
android:id="#+id/root"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<com.example.spinnerbuttonlib.spinnerbutton.Spinnerbutton
android:id="#+id/sbp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="8dp"
custom:myTextAppearence="#style/SmallTextGray" />
</RelativeLayout>
If you still have the problem, try to use the default xmlns namespace, like this :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:custom="http://schemas.android.com/apk/res-auto"
android:id="#+id/root"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<com.example.spinnerbuttonlib.spinnerbutton.Spinnerbutton
android:id="#+id/sbp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="8dp"
custom:myTextAppearence="#style/SmallTextGray" />
</RelativeLayout>
I think you will have better luck if your custom XML namespace is:
xmlns:custom="http://schemas.android.com/apk/res-auto"
change layout:
android:id="#+id/root"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<com.example.spinnerbuttonlib.spinnerbutton.Spinnerbutton
xmlns:custom="http://schemas.android.com/apk/res/android"
android:id="#+id/sbp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="8dp"
custom:myTextAppearence="#style/SmallTextGray" />
try with this in attrs.xml
from
<attr name="myTextAppearence" format="reference" />
to this
<attr name="myTextAppearence" format="integer" />
and
int textStyleId = a.getResourceId(
R.styleable.Spinnerbutton_myTextAppearence, -1); in Spinnerbutton() constructor
to
int textStyleId = a.getInt(
R.styleable.Spinnerbutton_myTextAppearence, -1);
it will work

How to set style or font to text of a TextView in android?

I want to set style or font to the text in a TextView like the image shown below:
<TextView
style="#style/CodeFont"
android:text="#string/hello" />
You need to Make that codefont style:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="CodeFont" parent="#android:style/TextAppearance.Medium">
<item name="android:layout_width">fill_parent</item>

You need a custom font and then you can do this:
Typeface mFont = Typeface.createFromAsset(getAssets(), "fonts/myFont.ttf");
MyTextView.setTypeface(mFont);
You have to create a "fonts" folder in your assets folder. Drop your font in there.
You could also create a custom TextView of course. Refer to this answer, I gave a while back, if you prefer that.
There is another way if you want to change it on many TextViews, Use a class:
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();
}
private void init() {
if (!isInEditMode()) {
Typeface tf = Typeface.createFromAsset(getContext().getAssets(), "fonts/Ubuntu-L.ttf");
setTypeface(tf);
}
}
}
and in the Layout replace:
<TextView
...
/>
With:
<com.WHERE_YOUR_CLASS_IS.MyTextView
...
/>
You could create a layout.xml file that would have your textview in it. Something like :
textView.xml
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
style="#android:style/Holo.ButtonBar" >
If you dont want this then you could create your custom style. Something like this :
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="Custom" parent="#android:style/TextAppearance.Large" >
<item name="android:typeface">monospace</item>
</style>
</resources>
and in the layout file change the style to something like :
style="#style/Custom"
