The following constructor call attempts to style my custom RelativeLayout2 using the defStyleRes parameter but it has no effect. I ported this sample project to AndroidStudio and it worked ok.
public RelativeLayout2(Context context, IAttributeSet attributeSet)
: base(context, attributeSet, 0, Resource.Style.RelativeLayout2)
{
}
styles.xml
<resources>
<style name="RelativeLayout2">
<item name="android:layout_width">40dp</item>
<item name="android:layout_height">300dp</item>
<item name="android:background">#114499</item>
<item name="android:padding">50dp</item>

// Set our view from the "main" layout resource
SetContentView(Resource.Layout.activity_main);
}
}
public class RelativeLayout2 : RelativeLayout
{
public RelativeLayout2(Context context, IAttributeSet attributeSet)
: base(context, attributeSet, 0, Resource.Style.RelativeLayout2)

}
}
}
Update (2018.09.12)
I tried styling a TextView as well, and set it's style's parent to android:Widget.TextView but it also had no effect.
styles.xml
<style name="TextView2" parent="android:Widget.TextView">
<item name="android:background">#204090</item>
</style>

public class TextView2 : TextView
{
public TextView2(Context context, IAttributeSet attributeSet)

android:layout_height="wrap_content"
android:text="asdfasdfasdfasfasfasdfasfdasdfasfasdf"

<!--style="#style/TextView2"-->
</InflationWithStyle.RelativeLayout2>
The following constructor call attempts to style my custom RelativeLayout2 using the defStyleRes parameter but it has no effect.
Neither the Styles and Themes documentation nor the Style resource documentation implies that the //style/#name value can be a View name and have things "magically linked". Instead, they both use a style attribute on the View, e.g.
<?xml version="1.0" encoding="utf-8"?>
<CustomeView.RelativeLayout2
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
style="#style/RelativeLayout2">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="An utter lack of style."/>
</CustomeView.RelativeLayout2>
I have tested your code with this method, it works fine.

Is there a way to change the theme of a TextInputLayout programmatically in Android.
If I have the following TextInputLayout for ex.:
<android.support.design.widget.TextInputLayout
android:id="#+id/label"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:paddingTop="16dp"
android:theme="#style/TextInputLayoutTheme"
app:errorTextAppearance="#style/Error">
<android.support.v7.widget.AppCompatEditText
android:id="#+id/edit_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingBottom="8dp"
android:paddingTop="8dp"/>
</android.support.design.widget.TextInputLayout>
Could I somehow change this line android:theme="#style/TextInputLayoutTheme" to another theme programmatically?
There is no way to change theme of any view or any layout at runtime. Because of themes and styles are applied during creation of view, recursively. (Themes also applies child views of layouts)
But, you can change that theme before creation of view using XML layout or programmatically.
Programmatically:
Method 1 - Create TextInputLayout programmatically with wrapping Context with android.view.ContextThemeWrapper and use.
TextInputLayout layout = new TextInputLayout(new ContextThemeWrapper(getContext(), R.style. TextInputLayoutTheme));
Method 2 - Extend TextInputLayout and use your own layout. Pass ContextThemeWrapper as context.
public class MyTextInputLayout extends TextInputLayout {
public MyTextInputLayout(Context context) {
super(new ContextThemeWrapper(context, R.style.AppTheme));
}
public MyTextInputLayout(Context context, AttributeSet attrs) {
super(new ContextThemeWrapper(context, R.style.AppTheme), attrs);
}
public MyTextInputLayout(Context context, AttributeSet attrs, int defStyleAttr) {
super(new ContextThemeWrapper(context, R.style.AppTheme), attrs, defStyleAttr);
}
}
Now, you can use MyTextInputLayout in your XML layout
With XML Layout:
1) In attrs.xml file, create new attribute named textInputLayoutTheme
<attr name="textInputLayoutTheme" format="reference"/>
2) In your AppTheme in styles.xml file set your #style/TextInputLayoutTheme as textInputLayoutTheme.
<resources>
<style name="AppTheme" parent="PARENT_THEME">
<item name="textInputLayoutTheme">#style/TextInputLayoutTheme</item>
</style>
<style name="AppTheme.Secondary">
<item name="textInputLayoutTheme">#style/TextInputLayoutTheme_Secondary</item>
</style>
</resources>
3) In your layout.xml file, set ?attr/textInputLayoutTheme as a TextInputLayout theme
<android.support.design.widget.TextInputLayout
android:id="#+id/label"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:paddingTop="16dp"
android:theme="#?attr/textInputLayoutTheme"
app:errorTextAppearance="#style/Error">
Now, when you change your application theme from AppTheme to AppTheme.Secondary TextInputLayoutTheme_Secondary will be used as a theme of your TextInputLayout instead of TextInputLayoutTheme.
Unfortunately the accepted answer is not working for me.
My solution was to wrap TextInputLayout in a custom layout.
view_input_layout_wrapper.xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:theme="#style/AppThemeMaterial"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.google.android.material.textfield.TextInputLayout
android:id="#+id/til"
style="#style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<com.google.android.material.textfield.TextInputEditText
android:id="#+id/edit_text"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</com.google.android.material.textfield.TextInputLayout>
</FrameLayout>
TextInputLayoutWrapper
class TextInputLayoutWrapper(context: Context) : FrameLayout(context) {
var inputLayout: TextInputLayout
private set
init {
inflate(context, R.layout.view_input_layout_wrapper, this)
inputLayout = findViewById(R.id.til)
}
}
Implementation in the view (fragment/activity):
private fun addNewField(fieldName: String) {
val textInputLayoutWrapper = TextInputLayoutWrapper(
requireContext()
).apply {
inputLayout.hint = fieldName
}
fieldsContainerViewGroup.addView(textInputLayoutWrapper)
}
NOTE: My app theme is not material theme, so I must add theme="#style/AppThemeMaterial" in the root ViewGroup of the TextInputLayout.
<style name="AppThemeMaterial" parent="Theme.MaterialComponents.Light">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="android:windowBackground">#android:color/black</item>
</style>
I'm using the Calligraphy lib for Android to change the fonts in my app.
The problem is with the Toolbar. I don't know how to change the font.
This is my Toolbar :
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:titleTextAppearance="#style/Toolbar.TitleText"
android:background="#drawable/background_repeat"
app:popupTheme="#style/AppTheme.PopupOverlay" />
This is the TextAppearance in my style.xml :
<style name="Toolbar.TitleText" parent="TextAppearance.Widget.AppCompat.Toolbar.Title">
<item name="fontPath">fonts/Raleway-ExtraBoldItalic.ttf</item>
<item name="android:textSize">50sp</item>
</style>
This is not working. I can change the size of the text (in this example, 50sp is working). But impossible to change the font.
The problem is that Toolbar creates TextViews for title and subtitle programmatically inside itself.
It means that it doesn't use wrapped LayoutInflater by Calligraphy.
Instead it uses system Typefaces depending on fontFamily and fontStyle from textAppearence attribute.
But Calligraphy listens for GlobalLayout changes and tries to load style from theme.
So what I've done:
Add activity theme and customize ActionBarStyle:
<style name="ActivityTheme" parent="AppTheme.Base">
<item name="android:actionBarStyle">#style/ActionBarStyle</item>
</style>
<style name="ActionBarStyle" parent="Widget.AppCompat.Light.ActionBar.Solid">
<item name="android:titleTextStyle">#style/ToolbarTitleTextAppearance</item>
</style>
<style name="ToolbarTitleTextAppearance" parent="TextAppearance.AppCompat.Widget.ActionBar.Title">
<item name="android:textSize">20sp</item>
<item name="fontPath">fonts/Roboto-Medium.ttf</item>
</style>
If you don't want or cannot override toolbar theme, you can subclass Toolbar and use your custom toolbar instead of the system toolbar:
public class ToolbarPlus extends Toolbar {
public ToolbarPlus(Context context) {
super(context);
}
public ToolbarPlus(Context context, AttributeSet attrs) {
super(context, attrs);
}
public ToolbarPlus(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
#Override
public void setTitle(CharSequence title) {
if (title == null) {
title = "";
}
Typeface font = TypefaceUtils.load(getResources().getAssets(), "fonts/Roboto-BoldItalic.ttf");
super.setTitle(CalligraphyUtils.applyTypefaceSpan(title, font));
}
}
Replace "fonts/Roboto-BoldItalic.ttf" with your font.
You can also use this method for subtitle by overriding public void setSubtitle(CharSequence subtitle).
There is two way you can do this
1) By using style in style.xml file AnoDest told you
2) By using xml, in this way you will get more control over view, you need to create seprate xml file called appbar.xml and include it in your view
appbar.xml file
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
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="wrap_content"
android:background="#drawable/gradient_theme"
android:elevation="#dimen/smallPadding"
android:fitsSystemWindows="true">
<com.indussoft.lms.customUI.TextViewRobotoBold
android:id="#+id/tvTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Activity Name"
android:textStyle="bold"
android:textSize="#dimen/okTextSize"
android:layout_gravity="center"
android:gravity="center"
android:visibility="visible"
android:textColor="#color/white" />
<TextView
android:layout_width="wrap_content"
android:text="#string/accept"
fontPath="fonts/Roboto-Bold.ttf"
android:layout_height="wrap_content" />
</android.support.v7.widget.Toolbar>
And include it in your activity view such as
<include
layout="#layout/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
Nothing worked for me so this is the function that I wrote in my base activity to workaround the issue:
private void setToolBarFont() {
final Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
for (int i = 0; i < toolbar.getChildCount(); i++) {
final View child = toolbar.getChildAt(i);
if (child instanceof TextView) {
final TextView textView = (TextView) child;
CalligraphyUtils.applyFontToTextView(textView, TypefaceUtils.load(getAssets(), "fonts/my_font.ttf"));
}
}
}
p.s. this is an open issue on Calligraphy's GitHub page currently. Here's the link to the issue:
https://github.com/chrisjenx/Calligraphy/issues/295
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);
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: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

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
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>
<item name="android:layout_height">wrap_content</item>
<item name="android:textColor">#00FF00</item>
<item name="android:typeface">monospace</item>
</style>
</resources>
Straight from : http://developer.android.com/guide/topics/ui/themes.html
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"
