I've searched here and it doesn't seem like anyone has had this problem.
I'm following the Android Studio tutorials from here.
Basically what is happening is that my buttons look fine when I implement my XML code, but when I transfer over some of the XML code to my styles.xml and import it into my activity_main.xml file, my button changes its dimensions.
Here's my activity_main.xml file.
<?xml version="1.0" encoding="utf-8"?>

I hope I have not missed anything out. If you copy paste my code inside an empty activity activity_main.xml file, you should see something like this.
Now the problem:
I want to implement some styles for my buttons. I have updated my styles.xml as such. In this case I have a parent ScoreButton which only takes the background, whereas the child elements are the plus and minus, which takes the picture and description.
<resources>
<!-- Base application theme. -->
<style name="AppTheme" 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="ScoreButtons" parent="Widget.AppCompat.Button">
<item name="android:background">#drawable/button_background</item>
</style>
<style name="PlusButtons" parent="ScoreButtons">
<item name="android:src">#drawable/ic_plus</item>
<item name="android:contentDescription">#string/plus_button</item>
</style>
<style name="MinusButtons" parent="ScoreButtons">
<item name="android:src">#drawable/ic_minus</item>
<item name="android:contentDescription">#string/minus_button</item>
</style>
</resources>
And if I update one of my button's code as such, for instance, replacing #+id/decreaseTeam1 with the code below:
<ImageButton
android:id="#+id/decreaseTeam1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_centerVertical="true"
style="#style/PlusButtons"
android:onClick="decreaseScore" />
The minus button suddenly becomes inflated.
I read that child views override parent views, but I don't see how that can be a problem, since there is no change to the image size, nor have I compressed it.
The problem is that in the style definition, your ScoreButtons has Widget.AppCompat.Button as parent. This style defines a minHeight and minWidth, as follows:
<style name="Base.Widget.AppCompat.Button" parent="android:Widget">
<item name="android:background">#drawable/abc_btn_default_mtrl_shape</item>
<item name="android:textAppearance">?android:attr/textAppearanceButton</item>
<item name="android:minHeight">48dip</item>
<item name="android:minWidth">88dip</item>
<item name="android:focusable">true</item>
<item name="android:clickable">true</item>
<item name="android:gravity">center_vertical|center_horizontal</item>
</style>
So, in order to solve your problem, you just have to remove the parent from ScoreButtons style:
<style name="ScoreButtons">
<item name="android:background">#drawable/button_background</item>
</style>
You have an error in your style. You are using an ImageButton not a Button
So, you should write
<style name="ScoreButtons" parent="Widget.AppCompat.ImageButton"> // ImageButton
<item name="android:background">#drawable/button_background</item>
</style>
you are making a mistake while assigning a style. you need to use ImageButton instead of using Button.
Use this:
<style name="ScoreButtons" parent="Widget.AppCompat.ImageButton">
<item name="android:background">#drawable/button_background</item>
<item name="android:contentDescription">#string/minus_button</item>
</style>
Instead of this:
<style name="ScoreButtons" parent="Widget.AppCompat.Button">
<item name="android:background">#drawable/button_background</item>
<item name="android:contentDescription">#string/minus_button</item>
</style>

I am working in Neumorphism based designs in my project. I am using this library https://github.com/fornewid/neumorphism for Neumorphism effect. My issue is I can't able to change the background of the button or any other views.
This is my layout file

use this property to change background app:neumorph_backgroundColor="#color/background_color" in your xml
if not working, there is one method inside NeumorphButton is setBackgroundDrawable. you can set drawable programmatically
Edit
you can't set the custom background in this lib because it says
Setting a custom background is not supported.
Coming from this thread: Android Material Design Button Styles
I couldn't understand how to individually change the colors of the buttons, so that not all buttons are with the same color.
<item name="android:colorButtonNormal">#color/blue</item>
This solution works nice, but it changes the color of all buttons.
In API 22, we can change the color of the different buttons by using the backgroundTint, like so:
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:elevation="3dp"
android:backgroundTint="#color/orange"
android:text="#string/button1_text"
android:textAllCaps="true"
android:textColor="#color/white"
android:textSize="18sp" />
How can we do it in API 21 ?
That's the styles.xml that I have:
<style name="AppTheme" parent="#android:style/Theme.Material.Light">
<item name="android:actionBarStyle">#style/actionBarCustomization</item>
<item name="android:spinnerDropDownItemStyle">#style/mySpinnerDropDownItemStyle</item>
<item name="android:spinnerItemStyle">#style/mySpinnerItemStyle</item>
<item name="android:colorButtonNormal">#color/myDarkBlue</item>
</style>
<style name="actionBarCustomization" parent="#android:style/Widget.Material.Light.ActionBar">
<item name="android:background">#color/white</item>
<item name="android:titleTextStyle">#style/actionBarTextColor</item>
</style>
<style name="actionBarTextColor" parent="#android:style/TextAppearance">
<item name="android:textColor">#color/black</item>
</style>
Okay, I figured it out. Here is the way I solved it, I hope it helps someone else too (I am not saying that it's perfect).
I created a drawable material_ripple_effect.xml that looks like that:
<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="#color/black">
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="2dp" />
<solid android:color="#color/myOrange" />
</shape>
</item>
</ripple>
And then in the layout, where I have the button, I just set the ripple drawable as a background. In activity_main.xml:
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:elevation="3dp"
android:backgroundTint="#color/orange"
android:background="#drawable/material_ripple_effect"
android:text="#string/button1_text"
android:textAllCaps="true"
android:textColor="#color/white"
android:textSize="18sp" />
I am trying to maintain the material design ripple effect for devices with lollipop and above (21+) and stylize the button so that it doesn't have a large margin/space around it.
Example 1: Buttons with ripple effect but with margin/gap:
Example 2: Buttons with NO ripple effect and without the margin/gap:
I want the layout of Exmaple 2 with the ripple effect that is used in Example 1.
What my styles-v21 look like for Example 1 :
<?xml version="1.0" encoding="utf-8"?>
<resources>
... other styles ...
<style name="FacebookButton" parent="android:Widget.Material.Button">
<item name="android:colorButtonNormal">#ff3b5998</item>
<item name="android:layout_margin">0dp</item>
<item name="android:borderlessButtonStyle">#style/Widget.AppCompat.Button.Borderless</item>
</style>
<style name="GoogleButton" parent="android:Widget.Material.Button">
<item name="android:colorButtonNormal">#ffdd4b39</item>
<item name="android:layout_margin">0dp</item>
<item name="android:borderlessButtonStyle">#style/Widget.AppCompat.Button.Borderless</item>

<item name="android:colorButtonNormal">#ffdfa800</item>
<item name="android:layout_margin">0dp</item>
<item name="android:borderlessButtonStyle">#style/Widget.AppCompat.Button.Borderless</item>
</style>
</resources>
What my button layout looks like for Example 1:
<Button
android:id="#+id/login_with_facebook"
android:text="#string/login_with_facebook"
android:fontFamily="sans-serif-condensed"
android:textSize="16sp"
android:drawableLeft="#drawable/facebook_icon"
android:drawablePadding="25dp"
android:layout_width="match_parent"
android:layout_height="45dp"
android:layout_weight="16.88"
android:textColor="#ffffff"
android:gravity="left|center_vertical"
android:paddingLeft="45dp"
android:theme="#style/FacebookButton" />
<Button
android:id="#+id/login_with_google"
android:text="#string/login_with_google"
android:fontFamily="sans-serif-condensed"

android:textSize="16sp"
android:drawableLeft="#drawable/twitter_icon"

android:gravity="left|center_vertical"
android:layout_width="match_parent"
android:layout_weight="16.88"
android:textColor="#ffffffff"
android:paddingLeft="45dp"
android:theme="#style/TwitterButton" />
<Button
android:id="#+id/login_anonymously"
android:text="#string/login_anonymously"
android:fontFamily="sans-serif-condensed"
android:textSize="16sp"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="50"
android:textColor="#ffffffff"
android:theme="#style/SkipButton" />
Any idea how I can achieve the look of Example 2 while using the ripple methodology I've presented? Any links to resources or help would be appreciated. Thanks.
Extra:
I've already read over the following
Coloring Buttons in Android with Material Design and AppCompat
How to properly style material buttons in android
You can use android:background="?android:attr/selectableItemBackground" to get a rectangular ripple.
Alternatively, you can create your own drawable. Here's the XML for the framework's selectable item background:
drawable/item_background_material.xml:
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="?android:attr/colorControlHighlight">
<item android:id="#android:id/mask">
<color android:color="#android:color/white" />
</item>
</ripple>
I am trying to create a layout like this (the blue bubble):
However, in my XML below, the blue bubble extends to the whole width of the fragment though I have specified the width as wrap_content everywhere. Any ideas ?
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingBottom="5dp"

android:paddingLeft="17dp"
android:layout_alignParentRight="true"
android:gravity="right"
android:layout_gravity="right"

android:text="Rahul Agrawal is a good boy but he does not know what he wants." />
</RelativeLayout>
</RelativeLayout>
<style name="chat_text_message_style">

Check the size of the image used as background for RelativeLayout or change the width of the Layout.Using the same xml with 100dp of width.
UPDATE
The maxWidth of the TextView adjust it according to design.
It looks like this:
I need to design a this type button which should have a background with another small image in the center and the text at the bottom.
While the current I am using is a textview as below
<TextView
android:id="#+id/homeButton1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="5dp"
android:layout_weight="1"
android:background="#ffffff"
android:clickable="false"
android:focusable="false"
android:focusableInTouchMode="false"
android:gravity="center"
android:text="Button"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#drawable/button_color"
android:textStyle="bold" />
But i cannot put an image in its center.
If I use android:drawableTop
this is the image I get
How can this be feasible?
try compound drawables here is an example
<TextView
android:id="#+id/image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableTop="#drawable/image"
android:gravity="center"
android:text="#string/text" />
output:
Put a bellow line to your TextView xml and change "img_src" to your image.
android:drawableTop="#drawable/img_src"
UPDATE 1 :
drawableTop only support to draw above the text.
If you want to draw image on the center, here is a sample code.
<RelativeLayout
android:id="#+id/relativeLayout1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/background_image" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:src="#drawable/center_image" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/imageView1"
android:text="TextView" />
</RelativeLayout>
Check this one, works exactly as you want
<Button
android:id="#+id/btn"
style="#style/MyButton"
android:drawableTop="#drawable/btn_my"
android:text="SomeText" />
btn_my.xml // add this inside drawable folder
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/ic_launcher"
android:state_focused="true"
android:state_pressed="true" />
<item android:drawable="#drawable/ic_launcher"

android:state_pressed="true" />
<item android:drawable="#drawable/ic_launcher" android:state_focused="true" />
<item android:drawable="#drawable/ic_launcher"
android:state_focused="false"
android:state_pressed="false" />
</selector>
copy the below into styles.xml
<style name="MyButton">
<item name="android:layout_gravity">center_vertical</item>
<item name="android:layout_width">wrap_content</item>
