I am testing out my app for API21 on Android! Unfortunately, my buttons seem weird - there is some kind of background color added. The background images did not change - they are completely transparent except for the border. (The different text and size is due to the screenshot).
Here you see the buttons before and since API 21: http://imgur.com/9EEcl0o,yVEnJkI#0
I already tried android:elevation="0dp" and android:background="#android:color/transparent". Anybody knows why my buttons change? Thank you very much!
layout.xml:
<Button android:id="#+id/sm_achievements_btn"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1.1"
android:background="#drawable/menu_btn_selector"
android:onClick="showAchievements"
android:text="#string/sm_achievements_btn"
android:padding="#dimen/padding_std"
android:layout_marginTop="#dimen/margin_small"
android:textColor="#color/button_text"
android:textSize="#dimen/text_xlarge"
style="#style/lbm_button"/>
menu_btn_selector.xml:
<item android:drawable="#drawable/menu_button"
android:state_pressed="false"/>
style.xml:
<style name="lbm_button" parent="android:Theme.Holo.Light">
<item name="android:textAllCaps">false</item>
</style>
Material buttons have a default stateListAnimator that provides state-based elevation (e.g. 0dp when disabled, 1dp when enabled). You can clear it by setting android:stateListAnimator="#null" in your style or directly on the Button.
Here is what that would look like on your button XML:
<Button android:id="#+id/sm_achievements_btn"
...
android:textAllCaps="false"
android:stateListAnimator="#null" />
Also, you're using the wrong parent for your button style. You should never set a theme as the parent for a widget style. Regardless, here is what that should look like if you prefer that route:
<Button android:id="#+id/sm_achievements_btn"
...
style="#style/MyButtonStyle" />
<style name="MyButtonStyle" parent="android:Widget.Material.Light.Button">
<item name="android:textAllCaps">false</item>
<item name="android:stateListAnimator">#null</item>
</style>

I am trying to change the background color and text color of a material button-through style.
However, I see no change in IDE and as well as on phone.
Here is a screenshot of the issue.
The button next to cancel misbehaves, after checking in tons of attributes I fail to change background color.
Here is my XML:
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<com.google.android.material.button.MaterialButton
android:id="#+id/btn_login_skip"
style="#style/myMaterialButton.Unboxed"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/cancel"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintRight_toLeftOf="#id/btn_login_login" />
<com.google.android.material.button.MaterialButton
android:id="#+id/btn_login_login"
style="#style/myMaterialButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/pay_deail_submit_btn"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
Here is some style info:
<style name="myMaterialButton" parent="Widget.MaterialComponents.Button.OutlinedButton">
<item name="android:textColor">#color/colorPrimary</item>
<item name="strokeWidth">2dp</item>
<item name="android:background">#color/colorPrimaryDark</item>
</style>
Here are colors:
<color name="colorPrimary">#color/silver</color>
<color name="colorPrimaryDark">#2A2E43</color>
By Material Official Source you should use app:backgroundTint in your style
meanwhile for checking "Widget.MaterialComponents.Button.OutlinedButton" styles you should check buttons on Device or Emulator, sometimes buttons with this style dosent show good in IDE
MaterialButton is visually different from Button and AppCompatButton. One of the main differences is that AppCompatButton has a 4dp inset on the left and right sides, whereas MaterialButton does not.
You can use app:backgroundTint to change the color
With this you need to use
android:insetTop="0dp"
android:insetBottom="0dp"
As described in the official doc, you can use the backgroundTint attribute:
<style name="myMaterialButton" parent="Widget.MaterialComponents.Button.OutlinedButton">
<!-- Background color -->
<item name="backgroundTint">#color/...</item>
</style>
Don't use the android:background attribute to change the background color.
Here is the button :
<Button
android:id="#+id/btn_choose_photo"
style="#style/Widget.MaterialComponents.Button.TextButton.Dialog"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:drawableStart="#drawable/ic_camera"
android:drawablePadding="8dp"
android:text="#string/image_picker_dialog_choose_image"
android:textAlignment="textStart" />
I am using material themes, so this will be inflated into a material button
drawableStart has no effect at all, however drawableEnd, bottom and top work just fine
When I make the button tag a text view, drawableStart works
It seems like a bug or maybe I am missing something ?
Edit: My app theme is as follows :
<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
<!---colors-->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryVariant">#color/colorPrimaryVariant</item>
<item name="colorPrimaryDark">#color/colorPrimaryVariant</item>
<item name="colorSecondary">#color/colorSecondary</item>
<item name="colorSecondaryVariant">#color/colorSecondaryVariant</item>
<item name="colorAccent">#color/colorSecondary</item>
<!--
<item name="android:colorBackground">#color/colorBackground</item>
-->
<!--components-->
<item name="textInputStyle">#style/text_input_layout_style</item>
<item name="bottomSheetDialogTheme">#style/bottom_sheet_dialog_theme</item>
<item name="spinnerStyle">#style/spinner_style</item>
<item name="android:spinnerStyle">#style/spinner_style</item>
<item name="android:toolbarStyle">#style/toolbar_style</item>
<item name="toolbarStyle">#style/toolbar_style</item>
<item name="actionOverflowButtonStyle">#style/overflow_button_style</item>
<item name="android:actionOverflowButtonStyle">#style/overflow_button_style</item>
</style>
You should use app:icon like this:
In the layout:
<Button
...
app:icon="#drawable/ic_camera"
style="#style/Widget.MaterialComponents.Button.TextButton"
/>
It is displayed at the start, before the text label. You can change icon gravity, tint or size.
For more information
Using
android:drawableLeft
will solve the problem, but will not give you RTL(Right to left) support. If your end user uses a different language which follow RTL, then your Button will not support it.
Are you managing the Button's property in the Activity or Fragment, as technically speaking,
android:drawableStart
should work.
You can change to "App compat button"
<androidx.appcompat.widget.AppCompatButton
android:id="#+id/continuar_anonimo_button"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_gravity="center"
app:backgroundTint="#color/greenPrimary"
android:background="#drawable/corner_boton_outline"
android:text="Continuar anonimamente"
android:paddingLeft="15dp"
android:drawableStart="#drawable/ic_google_color"
style="?android:textAppearanceSmall"/>
Use android:drawableLeft
android:drawableLeft="#drawable/ic_phone"
android:backgroundTint="#android:color/white"
In order to use Chip and ChipGroup, I set Application style extends Theme.MaterialComponents.Light.NoActionBar int manifests.xml, then I set Button "android:background" attr, but it does not effect! why? and what can I do?
This is my style:
<style name="AppBaseTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
<item name="colorPrimary">#color/primary_material_light</item>
<item name="colorPrimaryDark">#color/header_color</item>
<item name="actionBarSize">48dp</item>
<item name="android:screenOrientation">portrait</item>
<!--<item name="buttonStyle">#style/AntButton</item>-->
<!--<item name="materialButtonStyle">#style/AntButton</item>-->
<!--<item name="android:button"></item>-->
<!--<item name="android:progressTint">#color/ffc000</item>-->
<item name="colorAccent">#color/ffc000</item>
</style>
<style name="AntButton" 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>
<!--<item name="android:colorButtonNormal">#color/white</item>-->
</style>
I have tried to change buttonStyle and materialButtonStyle, but not effect too!
this is my layout XML:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/ll_popup"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="#color/white"
android:divider="#drawable/shape_divider_05dp"
android:orientation="vertical"
android:showDividers="beginning|middle">
<!--only can use backgroundTint to change background color-->
<Button
android:id="#+id/item_popupwindows_Photo"
android:layout_width="match_parent"
android:layout_height="55dp"
android:backgroundTint="#color/white"
android:text="Pictrue"
android:textColor="#color/c_666666"
android:textSize="16sp" />
<!--background not effect !!-->
<Button
android:id="#+id/item_popupwindows_cancel"
android:layout_width="match_parent"
android:layout_height="55dp"
android:background="#color/white"
android:text="cancel"
android:textColor="#color/c_666666"
android:textSize="16sp" />
</LinearLayout>
</LinearLayout>
this is result :
Because I have used Chip and ChipGroup in APP, I have to user theme extends MaterialComponents! do you know how to resolve it ？please tell me, thanks!
in this page Can't use android:background with button from the new material components, the author wants to change the default padding, but I want to change the backgroundDrawable, so, it does not work for me.
If you want a true Button, but one that you can modify like the framework Button (instead of the MaterialButton), then you can explicitly specify the framework version in your layout file. Replace this:
<Button
android:id="#+id/item_popupwindows_cancel"
... />
with this:
<android.widget.Button
android:id="#+id/item_popupwindows_cancel"
... />
This will give you what it says on the tin: an android.widget.Button, which should respond to styling the way you expect.
Similarly, you could use a <androidx.appcompat.widget.AppCompatButton> if you want support library features but not material components features.
In this particular case, the LinearLayout holding your second Button seems to have a white background color. That means you don't need to explicitly specify a white background for your Button; you can just let the LinearLayout's background show through.
This can be accomplished by using the "Text Button" style of MaterialButton:
style="#style/Widget.MaterialComponents.Button.TextButton"
Use this code for change the color
app:backgroundTint="#color/primaryColor"
You can also use ImageButton instead of Button from material components. android:background is working on ImageButton.
<ImageButton
android:id="#+id/item_popupwindows_cancel"
... />
I am trying to get some buttons to be use the Material Design style (in particular accentColor tinting) for Android 4.4 devices using the AppCompat library. I have had success with the following:
<android.support.v7.widget.AppCompatButton
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/continue_button"
android:id="#+id/continue_button"
android:layout_gravity="center_horizontal|bottom"
style="#style/CompatButton"
android:theme="#style/ThemeOverlay.AppCompat.Dark"/>
where "#style/CompatButton" has "Widget.AppCompat.Button.Colored" for a parent. However some of my buttons are the same but instead of declaring the style in the element, I attach the style as the default "buttonStyle" in the theme being used:
<style name="AppTheme">
...
<item name="android:buttonStyle">#style/CompatButton</item>
<item name="colorAccent">#color/flow_accent</item>
...
</style>
and
<android.support.v7.widget.AppCompatButton
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/continue_button"
android:id="#+id/continue_button"
android:layout_gravity="center_horizontal|bottom"
android:theme="#style/ThemeOverlay.AppCompat.Dark"/>
These buttons are showing up with the default, non-Material stylings. This also seems to happen with ProgressBar. Can anyone see what's wrong with this and if there's a workaround without having to explicitly define the button style?
Oops, that was dumb. Obviously ThemeOverlay wipes out the previous theme, including the buttonStyle definition. For it to work we have to add the buttonStyle back in:
<style name="FlowOverlay" parent="ThemeOverlay.AppCompat.Dark">
<item name="android:buttonStyle">#style/CompatButton</item>
</style>
<android.support.v7.widget.AppCompatButton
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/continue_button"
android:id="#+id/continue_button"
android:layout_gravity="center_horizontal|bottom"
android:theme="#style/FlowOverlay"/>
though that loses much of the convenience we wanted from default button styles in the first place.
I am trying to create a button whose text color is the colorAccent and whose background color is the default background color.
It looks like this:
I have tried default styles, but non of them have worked. Currently I have something like this but doesn't work:
styles.xml :
<style name="AppTheme.ButtonRaised" parent="Widget.AppCompat.Button.Colored">
<item name="colorButtonNormal">#android:color/transparent</item>
<item name="android:textColor">#color/colorAccent</item>
</style>
And layout:
<Button
app:theme="#style/AppTheme.ButtonRaised"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="date" />
And I am getting something like this:
I am not getting any effect of style or theme here. I have also tried with style tag, but it doesn't work.
apply theme with a style like this
<style name="ThemeButtonBlue" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorAccent">#color/colorPrimary</item>
<item name="colorButtonNormal">#android:color/transparent</item>
<item name="colorControlNormal">#color/white</item>
<item name="colorControlActivated">#color/colorPrimaryDark</item>
<item name="colorControlHighlight">#color/colorPrimary</item>
</style>
I am also struggling to do this effect. I could achieve something similar, but I don't know if its "material design approved".
I set the style to their button borderless colored and the elevation to 2dp because on material design they say that "Raised buttons have a default elevation of 2dp". But they don't give you xml layout examples which is annoying -_-
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
style="#style/Base.Widget.AppCompat.Button.Borderless.Colored"
android:elevation="2dp"
android:text="Button"/>
Keep in mind that the elevation tag does not show a shadow pre Lollipop devices.
