I have an Android application which uses Material design theme with backward compatibility through AppCompat.
There are multiple Textview's and EditText's in my application. I would like the same properties to be applied to all these TextView's and EditText's across the application. In order to achieve this, i have defined a custom style as shown below:
<!-- Base application theme. -->
<style name="ParentTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
<style name="ArabicTheme" parent="ParentTheme">
<item name="android:editTextStyle">#style/arabicEditText</item>
<item name="android:textViewStyle">#style/arabicTextView</item>
</style>
<style name="arabicEditText" parent="#android:style/Widget.EditText">
<item name="android:gravity">right</item>
<item name="android:ellipsize">end</item>
</style>
<style name="arabicTextView" parent="#android:style/Widget.TextView">
<item name="android:gravity">right</item>
</style>
In my AndroidManifest.xml file under the <Application> tag, i have set android:theme="#style/ArabicTheme".
Below is the output of the activity:
As seen in the above output, the Style is being applied to TextView only. However, The same is not being applied to EditText.
Incase, if i explicitly specify these properties to the EditText in the corresponding Actitivy's xml as shown below:
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="textPersonName"
android:hint="Name"
android:ellipsize="end"
android:gravity="right"
android:ems="10"
android:layout_below="#+id/textView"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_marginTop="16dp"
android:id="#+id/editText" />
i.e I have explicitly added android:ellipsize="end" and android:gravity="right" to the <EditText>, and only then the output is as expected:
Like i said, i have multiple TextView's and EditText's and i cannot explicitly add these properties to all of them. So, is there a way i can achieve this using Styles or any other approach? Am i doing something wrong here?
Your approach is correct. Just remove android: from the editText's attribute name:
<item name="editTextStyle">#style/arabicEditText</item>
I cannot explain this though. I guess appCompat things don't reuse android attributes, but add another ones with similiar names. Same goes with colorPrimary, srcCompat and others.
I have been doing this
public class LightEditText extends android.widget.EditText{
public LightEditText(Context context) {
super(context);
setFont();
}
public LightEditText(Context context, AttributeSet attrs) {
super(context, attrs);
setFont();
}
public LightEditText(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
setFont();
}
#TargetApi(Build.VERSION_CODES.LOLLIPOP)
public LightEditText(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
super(context, attrs, defStyleAttr, defStyleRes);
setFont();
}
/**
* This method is used to set the given font to the TextView.
*/
private void setFont() {
Typeface typeface = TypefaceCache.get(getContext().getAssets(), "fonts/Roboto-Light.ttf");
setTypeface(typeface);
}
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
}
}
Then inside your xml file
<com.packagename.LightEditText
android:id="#+id/edtTaskName"
android:layout_height="wrap_content"
android:layout_width="match_parent"/>
Do the above method for setting common properties(fontType,style..etc) to editext

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
I've found an improvement that may help not to hardcode view values into java classes in my android app. I wonder how can i get it to work. I want to to use this kind of view in my adapter (that means that i cannot use #style attribute in my layout's root). What am i doing wrong?
Code:
styles.xml:
<resources>
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="customViewStyleRef">#style/CustomViewStyle</item>
</style>
<attr name="customViewStyleRef" format="reference"/>
<style name="CustomViewStyle" parent="#android:style/Widget.TextView">
<item name="android:layout_margin">10dp</item>
</style>
</resources>
View class:
public class CustomView extends View {
public CustomView(Context context) {
super(context, null);
}
public CustomView(Context context, AttributeSet attrs) {
super(context, attrs, R.attr.customViewStyleRef);
}
public CustomView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, R.attr.customViewStyleRef);
}
public void init(#NonNull ViewGroup parentView) {
inflate(getContext(), R.layout.custom_view, parentView);
}
}
View layout:
<merge xmlns:android="http://schemas.android.com/apk/res/android">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#f00"
android:textColor="#fff"
android:textSize="50sp"
android:text="test text"/>
</merge>
Problem: The TextView container does not have any padding that i specified in styles.xml (see the image).
You should initialize the TextView, then use the style for the TextView or you can solve this problem by putting style name inside the TextView and use an id for the TextView it will help for using it.
<TextView
android:id="#+id/custom_tv"
style="#style/CustomViewStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#f00"
android:textColor="#fff"
android:textSize="50sp"
android:text="test text"/>
I think i've figured this out. My built files were somehow cached and i couldn't get it to work. And i took a wrong testing parameter. My approach worked 😁
I have set up the following theme for my app:
<style name="AppTheme" parent="Theme.Sherlock.Light">
<item name="android:textViewStyle">#style/RobotoTextViewStyle</item>
</style>
<style name="RobotoTextViewStyle" parent="android:Widget.TextView">
<item name="android:fontFamily">sans-serif-light</item>
</style>
Therefor when I create a TextView I get the "roboto light" font which I want. Some TextViews however, I would like to set the textStyle="bold" attribute but it doesn't work since the light font doesn't have a "native" (?) bold variant.
On the other side if I programmatically use the setTypeface method I could get a bold font:
textView.setTypeface(textView.getTypeface(), Typeface.BOLD);
This font is derived from the roboto light and looks really good.
I would like to have this bold light font but I wonder what the most elegant way to do it is.
Can it be done solely using xml?
What is the best implementation if I need to create a "BoldTextView extends TextView"?
I ended up creating a class for it:
public class FakeBoldTextView extends TextView {
public FakeBoldTextView(Context context) {
super(context);
setTypeface(getTypeface(), Typeface.BOLD);
}
public FakeBoldTextView(Context context, AttributeSet attrs) {
super(context, attrs);
setTypeface(getTypeface(), Typeface.BOLD);
}
public FakeBoldTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
setTypeface(getTypeface(), Typeface.BOLD);
}
}
And using it in XML like this:
<the.package.name.FakeBoldTextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Example string" />
In my Android application I need to apply style for a group of buttons, instead of styling each button individual. Something like this:
<?xml version="1.0" encoding="utf-8"?>
<!-- put here style="#ststyle/Button_Style" -->
<Button android:id="#+id/button1" android:text="#string/b01" />
<Button android:id="#+id/button2" android:text="#string/b02" />
<Button android:id="#+id/button4" android:text="#string/b03" />
<!-- end style -->
You can write the style for button like this ;
style_btn.xml
<style name="style_btn" parent="Wrap">
<item name="android:background">#drawable/btn_bg</item>
<item name="android:gravity">center</item>
<item name="android:textColor">#android:color/white</item>
<item name="android:textStyle">bold</item>
<item name="android:layout_marginTop">4dp</item>
<item name="android:minWidth">90dp</item>
</style>
apply that style to your button :
<Button
android:id="#+id/attach_file"
style="#style/style_btn"
android:layout_centerVertical="true"
android:background="#drawable/orange_bg"
android:drawablePadding="10dp"
android:drawableRight="#drawable/attach"
android:text="#string/str_email_attach" />
If you need the style to all of the buttons in your application, mention in your App theme style, Then no need to apply for every button.
<style name="YourTheme" parent="android:Theme.Light">
<item name="android:buttonStyle">#style/Button</item>
</style>
If you need the style to particluar button , then apply to every button
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
style="#style/Button"
android:text="Button" />
I know I'm late joining the party but I stumbled across this when trying to figure out the same problem myself.
What I did was:
Depending on how may button groups you have (say 3 for example) you need to subclass button and create three custom button classes (see below)
//Custom button 1
public class CustomButton1 extends Button {
public CustomButton1(Context context, AttributeSet attrs) {
super(context, attrs, R.attr.attrStyle1);
}
public CustomButton1(Context context, AttributeSet attrs, int defStyle) {
super(context, null, R.attr.attrStyle1);
}
}
//Custom button 2
public class CustomButton2 extends Button {
public CustomButton2(Context context, AttributeSet attrs) {
super(context, attrs, R.attr.attrStyle2);
}
public CustomButton2(Context context, AttributeSet attrs, int defStyle) {
super(context, null, R.attr.attrStyle2);
}
}
//Custom button 3
public class CustomButton3 extends Button {
public CustomButton3(Context context, AttributeSet attrs) {
super(context, attrs, R.attr.attrStyle3);
}
public CustomButton3(Context context, AttributeSet attrs, int defStyle) {
super(context, null, R.attr.attrStyle3);
}
}
You can see from the custom classes I have passed a custom attr. These I define in my styles.xml and use them as reference. See my styles.xml below:
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
</style>
<style name="theme1">
<item name="#attr/attrStyle1">#style/CustomButton1</item>
<item name="#attr/attrStyle2">#style/CustomButton2</item>
<item name="#attr/attrStyle3">#style/CustomButton3</item>
<item name="android:background">#color/warning_yellow_colour</item>
</style>
<style name="CustomButton1" parent = "#android:style/Widget.Button">
<item name="android:textColor">#color/white_colour</item>
<item name="android:padding">20dp</item>
<item name="android:background">#color/banner_background_sensor_colour</item>
</style>
<style name="CustomButton2" parent = "#android:style/Widget.Button">
<item name="android:textColor">#color/white_colour</item>
<item name="android:padding">20dp</item>
<item name="android:background">#color/button_red_colour</item>
</style>
<style name="CustomButton3" parent = "#android:style/Widget.Button">
<item name="android:textColor">#color/white_colour</item>
<item name="android:padding">20dp</item>
<item name="android:background">#color/text_blue_colour</item>
</style>
<attr name="attrStyle1" format="reference"/>
<attr name="attrStyle2" format="reference"/>
<attr name="attrStyle3" format="reference"/>
By linking the style to the attr, you then apply that style to your custom class, which you can then duplicate as many times as needed
CustomButton1 theme1 = (CustomButton1)findViewById(R.id.theme1);
CustomButton2 theme2 = (CustomButton2)findViewById(R.id.theme2);
CustomButton3 theme3 = (CustomButton3)findViewById(R.id.theme3);
Hopefully this is of benefit to someone!
I want to have a line below a text view with a blue color I came across this post in this post having this as a one of the answer I tried it and is working fine but I want to change the color of the textview and the line below it.
just add this style:
style="?android:listSeparatorTextViewStyle"
to your TextView
I also have tried extracting the style but it is giving me error while inheriting the said style
My style is as follows
<style name="blueBoldText" parent="?android:listSeparatorTextViewStyle">
<item name="android:textColor">#color/DarkTurquoise</item>
<item name="android:textStyle">bold</item>
</style>
Actually, the value of the attribute
?android:listSeparatorTextViewStyle
is
#android:style/Widget.Holo.Light.TextView.ListSeparator
So you can inherit this style instead.
You can extend TextView and set listSeparatorTextViewStyle.
public class HeaderView extends TextView {
public HeaderView(Context context) {
super(context, null, android.R.attr.listSeparatorTextViewStyle);
}
public HeaderView(Context context,
AttributeSet attrs) {
super(context, attrs, android.R.attr.listSeparatorTextViewStyle);
}
}
then
<com.gmail.sikambr.alib.HeaderView
style="#style/your_style"
android:text="..."
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
