Finally I find the solution: instead of using android:colorControlHighlight
directly in theme SelectableItemBackground
, I should write another style:
<style name="SelectableItemTheme">
<item name="colorControlHighlight">@color/ripple_color</item>
</style>
Then:
<style name="SelectableItemBackground">
<item name="android:theme">@style/SelectableItemTheme</item>
<item name="android:background">?attr/selectableItemBackground</item>
</style>
Finally add style="@style/SelectableItemBackground"
to View
in layout.xml.
UPDATED ON 2016/8/26
After N's release, I found that sometimes we cannot use this method to set ripple color for some kind of View
(for example, the CardView
). Now I highly recommend developers using RippleDrawable
, which can also be declared in xml. Here is an example:
I want to show a ripple effect when user touches/clicks a CardView
above API21, and of course there should be another kind of feedback before Lollipop. So I should write:
<android.support.v7.widget.CardView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:foreground="@drawable/selectable_item_background"/>
and selectable_item_background
in drawable
folder:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="false" android:drawable="@android:color/transparent" />
<item android:drawable="@color/color_clicked" />
</selector>
selectable_item_background
in drawable-v21
folder:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/ripple_black" />
</selector>
finally, the ripple_black
in drawable
(or drawable-v21
) folder:
<ripple
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:color="@color/color_clicked"
tools:ignore="NewApi" /> <!--you can remove this line if it's in v21 folder-->
That's it. For other views, maybe you should use android:background="@drawable/selectable_item_background"
. Don't forget to set an OnClickListener
, OnTouchListener
or something like those for them, otherwise ripple won't show.
harrane and Liuting are right. The accepted answer is not the best way. Let me show in code how to change ripple color for pre-Lollipop versions and higher
Your AppTheme should inherit from any AppCompat theme and contain colorControlHighlight attribute (without 'android:' prefix)
<!-- Application theme. -->
<style name="AppTheme" parent="@style/Theme.AppCompat.Light.NoActionBar">
<item name="colorControlHighlight">#40ffffff</item>
</style>
Your view should contain clickable="true" (or should have a click listener set programmatically) and background should be "?attr/selectableItemBackgroundBorderless" or "?attr/selectableItemBackground" :
<LinearLayout
...
android:clickable="true"
android:background="?attr/selectableItemBackgroundBorderless"/>
Note: that if your parent view has white background you won't see ripple effect since it's white. Change colorControlHighlight value for a different color
Also, if you want different ripple colors on different activities you can set personal theme for each activity in Manifest file, for example:
<activity
android:name="com.myapp.GalleryActivity"
android:theme="@style/RedRippleTheme"
/>
You can change attributes of Activity Theme for each fragment in runtime. Just overwrite them before fragment was inflated with your custom style and apply to a current Theme:
in values/styles.xml
<style name="colorControlHighlight_blue">
<item name="colorControlHighlight">@color/main_blue_alpha26</item>
</style>
Then, in your fragment before inflation in onCreateView()
:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
getContext().getTheme().applyStyle(R.style.colorControlHighlight_blue, true); //blue ripple color
View view = inflater.inflate(R.layout.my_fragment_layout, container, false);
return view;
}
This style will work only for this fragment
You can change the ripple color for each view seperately using
colorControlHighlight
attribute, it doesn't work if you apply them to a view directly:
<TextView
...
colorControlHighlight="#40ffffff"/> <!-- DOESN'T WORK -->
you should apply it as a theme:
<TextView
...
android:theme="@style/colorControlHighlight_blue"/>
P.S. Also, sometimes this approach helps if you have unknown issues with ripple and you can't figure it out. In my case, I used 3rd party sliding lib which messed up ripple effects for the entire layout and adding explicitly this theme to all clickable views worked out for me.
It's showing ripple effect with color on API +21, and simple gray background on press for API -21. Add this style:
<style name="AppTheme.MyRipple">
<item name="colorControlHighlight">@color/your_color</item>
<item name="android:background">?selectableItemBackgroundBorderless</item>
</style>
And set it to the view:
<Button
...
android:theme="@style/AppTheme.MyRipple" />
The accepted answer is wrong.
The correct way to use is what Liuting mentioned in the comment.
Use colorControlHighlight
instead of android:colorControlHighlight
for changing the default colorControlHighlight
from AppCompat
* Please refer to http://android-developers.blogspot.co.uk/2014/10/appcompat-v21-material-design-for-pre.html in the Theming section *
Use the below steps:
1. Make changes to button view in your layout.xml
2. Add new styles in styles.xml
your_layout.xml
<Button
android:id="@+id/setup_submit_button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="16dp"
android:text="@string/action_sign_in"
android:textStyle="bold"
android:background="@color/colorPrimary"
android:textColor="@color/white"
style="@style/SelectableItemBackground"
android:foreground="?android:attr/selectableItemBackground"/>
-The style attribute calls the style that we created.
-Foreground attribute calls the andorid's default selectable attribute.
styles.xml
<style name="SelectableItemTheme">
<item name="colorControlHighlight">@color/white</item>
</style>
<style name="SelectableItemBackground">
<item name="android:theme">@style/SelectableItemTheme</item>
<item name="android:background">?attr/selectableItemBackground</item>
</style>
