So, if I have a shape:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<corners
android:radius="10dp"/>
</shape>
And I want to have that shape in a selector:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/someDrawable" android:state_focused="true" android:state_pressed="true"/>
<item android:drawable="#drawable/someOtherDrawable" android:state_focused="false" android:state_pressed="true"/>
<item android:drawable="#drawable/someOtherOTHERDrawable"/>
</selector>
How could I use my shape in my selector AND set the color of it? Is that even possible in to do in the XML? Would I have to use an <include /> tag like this:
<item >
<include layout="#drawable/myShape"
android:color="#987" />
</item>

I want to add a ripple effect with rounded corners rectangle with a selector for navigation view item. But it keeps adding the gray rectangle ripple effect.
navigation view
<android.support.design.widget.NavigationView
android:id="#+id/navigation_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
android:layout_marginEnd="8dp"
app:itemIconTint="#color/drawer_item"
app:itemTextColor="#color/drawer_item"
app:itemBackground="#drawable/drawer_item_bg"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:menu="#menu/bottom_app_bar_menu"/>
drawer_item_bg.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:drawable="#drawable/drawer_selected_item_bg"/>
<item android:state_checked="false" android:drawable="#android:color/transparent"/>
<item android:state_pressed="true" android:drawable="#drawable/custom_ripple_navitem"/>
<item android:state_selected="true" android:drawable="#drawable/custom_ripple_navitem"/>
<item android:state_focused="true" android:drawable="#drawable/custom_ripple_navitem"/>
custom_ripple_navitem.xml
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="#360074FF">
<item android:id="#android:id/mask">
<shape android:shape="rectangle">
<corners android:radius="8dp"/>
</shape>
</item>
The result is
With the Material Components you can use something like:
<com.google.android.material.navigation.NavigationView
app:itemShapeAppearanceOverlay="#style/ShapeAppearanceOverlay.NavItem.Rounded"
app:itemShapeFillColor="#color/selector_navitem"
android:theme="#style/ThemeOverlay.NavItem.Ripple"
../>
With the app:itemShapeAppearanceOverlay attribute you can define a custom shape for the each item:
<style name="ShapeAppearanceOverlay.NavItem.Rounded" parent="">
<item name="cornerFamily">rounded</item>
<item name="cornerSize">8dp</item>
</style>
With the app:itemShapeFillColor attribute you can define the color used to fill the shape:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:alpha="0.50" android:color="#color/primaryColor" android:state_pressed="true"/>
<item android:alpha="0.12" android:color="#color/primaryColor" android:state_activated="true"/>
<item android:alpha="0.12" android:color="#color/primaryColor" android:state_checked="true"/>
<item android:color="#android:color/transparent"/>
</selector>
Finally use the android:theme to override the color used by the ripple.
<style name="ThemeOverlay.NavItem.Ripple" parent="">
<item name="android:colorControlHighlight">#android:color/transparent</item>
</style>
Note: it requires the version 1.1.0 of the Material Components library.
"Solution"
I started experimenting with ripple effect when I found this question, and after some time I finished with this code.
Note: It is not real ripple effect, just a fake one. Let me know if you'll make an improved version of it.
#layout/your_layout.xml
<android.support.design.widget.NavigationView
...
android:theme="#style/Widget_NavigationItem_NoRipple"
app:itemBackground="#drawable/drawer_item_background"/>
#values/styles.xml
<style name="Widget_NavigationItem_NoRipple">
<item name="android:colorControlHighlight">#android:color/transparent</item>
</style>
#drawable/drawer_item_background.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/drawer_item_shape" android:state_checked="true"/>
<item android:drawable="#drawable/drawer_item_ripple" android:state_pressed="true"/>
<item android:drawable="#android:color/transparent" android:state_pressed="false"/>
</selector>
#drawable/drawer_item_shape
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<corners android:radius="8dp"/>
<solid android:color="#color/selectedItemBackgroundColor"/>
</shape>
</item>
</layer-list>
#drawable/drawer_item_ripple
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="#android:color/transparent">
<item>
<shape android:shape="rectangle">
<corners android:radius="8dp"/>
<solid android:color="?attr/colorControlHighlight"/>
</shape>
</item>
</ripple>
I have this button XML, which has transparent background and when clicked, the color changes, so that it shows a "click effect".
Drawable XML:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- press-->
<item android:drawable="#android:color/transparent" android:state_pressed="false" />
<!-- focused-->
<item style="#style/AppTheme" android:drawable="#color/color_primary" android:state_pressed="true" />
<!-- normal-->
<item android:drawable="#android:color/transparent" />
</selector>
My question is, how to put border on this button? Or an XML example so you have the same result. Thank you!
create a drawable, similar to this, selected.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#ff0000"/>
<stroke
android:width="1dp"
android:color="#00ff00" />
</shape>
then change this line
<item
style="#style/AppTheme"
android:drawable="#color/color_primary"
android:state_pressed="true" />
to
<item
style="#style/AppTheme"
android:drawable="#drawable/selected"
android:state_pressed="true" />
the solid is the background color and the border is the stroke, you can create drawables that are used in the diferent states of the selector
You can do something like this:
1. First create a drawable file like this:
<shape android:shape="rectangle">
<!--apply button background transparent, full opacity-->
<solid android:color="#00ffffff"/>
<!--make button border solid color, nontransparent-->
<stroke android:color="#stroke color" android:width="2dp"/>
<corners android:radius="2dp"/>
</shape>
then in your provided code replace these lines:
<!-- press-->
<item android:drawable="path to above drawable" android:state_pressed="false" />
<!-- focused-->
<item style="#style/AppTheme" android:drawable="#color/color_primary" android:state_pressed="true" />
<!-- normal-->
<item android:drawable="path to above drawable" />
as
<!-- press-->
<item android:drawable="path to above drawable" android:state_pressed="false" />
<!-- focused-->
<item style="#style/AppTheme" android:drawable="#color/color_primary" android:state_pressed="true" />
<!-- normal-->
<item android:drawable="path to above drawable" />
I have defined the below files in res folder.
styles_apptheme.xml
<?xml version="1.0" encoding="utf-8"?>
<!-- Generated with http://android-holo-colors.com -->
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="ButtonAppTheme" parent="android:Widget.Holo.Light.Button">
<item name="android:background">#drawable/apptheme_btn_default_holo_light</item>
</style>
</resources>
themes_apptheme.xml
<?xml version="1.0" encoding="utf-8"?>
<!-- Generated with http://android-holo-colors.com -->
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="AppTheme" parent="#style/_AppTheme"/>
<style name="_AppTheme" parent="Theme.AppCompat.Light">
<item name="android:editTextBackground">#drawable/apptheme_edit_text_holo_light</item>
<item name="android:buttonStyle">#style/ButtonAppTheme</item>
</style>
</resources>
In my Layout.xml file, i have defined my button as below
<Button
android:id="#+id/btnAddTitle"
android:layout_below="#id/edEnterTitleValue"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/btn_AddTitle"
android:layout_margin="20dp"
/>
If i add the below line to the button view above,
android:background="#style/ButtonAppTheme"
Application crashes saying that drawable resource should be set for the background attribute.
So i created the below drawable file - abc.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_window_focused="false" android:state_enabled="true"
android:drawable="#drawable/apptheme_btn_default_normal_holo_light" />
<item android:state_window_focused="false" android:state_enabled="false"
android:drawable="#drawable/apptheme_btn_default_disabled_holo_light" />
<item android:state_pressed="true"
android:drawable="#drawable/apptheme_btn_default_pressed_holo_light" />
<item android:state_focused="true" android:state_enabled="true"
android:drawable="#drawable/apptheme_btn_default_focused_holo_light" />
<item android:state_enabled="true"
android:drawable="#drawable/apptheme_btn_default_normal_holo_light" />
<item android:state_focused="true"
android:drawable="#drawable/apptheme_btn_default_disabled_focused_holo_light" />
<item
android:drawable="#drawable/apptheme_btn_default_disabled_holo_light" />
</selector>
If i set android:background="#drawable/abc" i dont see the style set in the button.
So please let me know how i can set the style for the button.
Thanks.
It would be rather simple if you do it this way.
First create a button_selector.xml in drawable folder.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="true" >
<shape android:shape="rectangle" >
<corners android:radius="5dp" />
<stroke android:width="1dip" android:color="#color/green_temp" />
<gradient android:angle="-90" android:startColor="#color/green_temp" android:endColor="#color/green_temp" />
</shape>
</item>
<item android:state_focused="true">
<shape android:shape="rectangle" >
<corners android:radius="5dp" />
<stroke android:width="1dip" android:color="#971E05" />
<solid android:color="#58857e"/>
</shape>
</item>
<item >
<shape android:shape="rectangle" >
<corners android:radius="5dp" />
<stroke android:width="1dip" android:color="#color/bright_green" />
<gradient android:angle="-90" android:startColor="#color/green_temp" android:endColor="#color/button_green" />
</shape>
</item>
</selector>
Add these colors in colors.xml of values folder.
<!-- Green -->
<color name="green_temp">#23A96E</color>
<color name="green_dark">#159204</color>
<color name="bright_green">#02D8B0</color>
<color name="button_green">#10a54a</color>
Finally in your desired button of layout.xml put background from above selector.
<Button
android:id="#+id/btnAddTitle"
android:layout_below="#id/edEnterTitleValue"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/btn_AddTitle"
android:background="#drawable/button_selector"
android:layout_margin="20dp"
/>
Then its all done your button will be styled with color you want.
Android Button Maker is online tool to generate buttons code for Android Apps. Android API provide Drawable Resources where XML file defines geometric shape, including colors, border and gradients.
These button is generating based on shape drawable XML code which load faster compare to normal png buttons. You can customize button properties in setting panel and get source code.
Check this link Button Maker
No need to crack brains...this tool make it simple
replace
android:background="#style/ButtonAppTheme"
with
style="#style/ButtonAppTheme"
and every thing is ok!
Try this out as alternative. create a drawable folder under res then create xml files and copypaste below code and try first then you customize as per your requirement.
button_bg.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#00acc1"/>
<stroke android:width="2dp" android:color="#ffffff"/>
<corners android:radius="2dp"/> </shape>
button_bg_pressed.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#006064"/>
<stroke android:width="1dp" android:color="#ffffff"/>
<corners android:radius="2dp"/> </shape>
button_selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_focused="true" android:state_pressed="true"
android:drawable="#drawable/button_bg_pressed" />
<item android:state_focused="false" android:state_pressed="true"
android:drawable="#drawable/button_bg_pressed" />
<item android:drawable="#drawable/button_bg" /> </selector>
And now in your button xml set the background as button_selector.xml
<Button
android:id="#+id/btnAddTitle"
android:layout_below="#id/edEnterTitleValue"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/btn_AddTitle"
android:background="#drawable/button_selector"
android:layout_margin="20dp"/>
This will do the job for you. You can customize your entire button style by this way.
If you want to have the default animation of button by material design and change button color, try this.
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="#dimen/padding_12"
android:text="button text here"
android:theme="#style/NavyBtn" />
in style.xml
<style name="NavyBtn" parent="Theme.AppCompat.Light">
<item name="colorButtonNormal">#020e39</item>
<item name="android:textColor">#FFFFFF</item>
</style>
In my project I have a ViewPager that is not linked to the action bar and I'm having problems with setting the font size of the text for the tabs. I'm using ViewPagerIndicator (v2.4.1) in combination with ActionBarSherlock (v4.3.1).
The layout I'm using is:
<com.viewpagerindicator.TabPageIndicator
android:id="#+id/artistIndicator"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<android.support.v4.view.ViewPager
android:id="#+id/artistPager"
android:layout_width="fill_parent"
android:layout_height="100dp"
android:minHeight="50dp" />
This is within a LinearLayout inside a ScrollView. The layout works as expected and I see no problems with the interaction between the ScrollView and my ViewPager.
Styling of the ViewPager and tabs is done with the following XML:
<style name="ArtistIndicatorTheme" parent="AppTheme">
<item name="vpiTabPageIndicatorStyle">#style/ArtistInfoTabPageIndicator</item>
</style>
<style name="ArtistInfoTabPageIndicator" parent="Widget.TabPageIndicator">
<item name="android:background">#drawable/tab_background</item>
<item name="background">#android:color/white</item>
<item name="android:textAppearance">#style/ArtistInfoTabPageIndicator.Text</item>
</style>
<style name="ArtistInfoTabPageIndicator.Text" parent="#style/TextAppearance.TabPageIndicator">
<item name="android:textColor">#drawable/tab_text_color</item>
<item name="android:textSize">#dimen/activity_position_artistinfo_font_size</item>
<item name="android:textStyle">bold</item>
</style>
The background of the tabs is handled by the following XMLs to create a actual tab-style look:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="false" android:state_selected="false" android:state_pressed="false" android:drawable="#drawable/tab_background_unselected" />
<item android:state_focused="false" android:state_selected="true" android:state_pressed="false" android:drawable="#drawable/tab_background_selected" />
<item android:state_focused="true" android:state_selected="false" android:state_pressed="false" android:drawable="#drawable/tab_background_unselected" />
<item android:state_focused="true" android:state_selected="true" android:state_pressed="false" android:drawable="#drawable/tab_background_selected" />
</selector>
And the two shape XMLs for selected:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- Bottom Line -->
<item>
<shape android:shape="rectangle" >
<solid android:color="#color/text_inverted" />
</shape>
</item>
<!-- Color of your action bar -->
<item android:bottom="2dip">
<shape android:shape="rectangle" >
<solid android:color="#color/text_inverted" />
</shape>
</item>
</layer-list>
and unselected:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- Bottom Line -->
<item>
<shape android:shape="rectangle" >
<solid android:color="#color/text_inverted" />
</shape>
</item>
<!-- Color of your action bar -->
<item android:bottom="2dip" android:right="2dip">
<shape android:shape="rectangle" >
<solid android:color="#color/text_important" />
</shape>
</item>
</layer-list>
The current font size is set by the following dimension:
<dimen name="activity_position_artistinfo_font_size">15dp</dimen>
Any indication on what I'm doing wrong?
I have an edittextview with a black colored border. How can I change this border color depending on the state, using a selector.
I tried this:
<EditText
android:layout_width="fill_parent"
android:layout_height="48dp"
android:background="#drawable/black_rounded_borders"
/>
black_rounded_borders.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="#FFFFFFFF" />
<stroke
android:width="2dp"
android:color="#drawable/selector_black_border" />
<corners
android:bottomLeftRadius="5dp"
android:bottomRightRadius="5dp"
android:topLeftRadius="5dp"
android:topRightRadius="5dp" />
</shape>
selector_black_border.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:color="#FF269ff5"/>
<item android:state_focused="true" android:color="#FF269ff5"/>
<item android:color="#FF000000"/>
</selector>
EDIT:
I changed selector_black_border.xml to color folder
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" android:color="#FF269ff5"/>
<item android:state_pressed="true" android:color="#FF269ff5"/>
<item android:state_selected="true" android:color="#FF269ff5"/>
<item android:state_focused="false" android:color="#FF000000"/>
<item android:state_pressed="false" android:color="#FF000000"/>
<item android:state_selected="false" android:color="#FF000000"/>
</selector>
<stroke
android:width="2dp"
android:color="#color/selector_black_border" />
But then it always remain in blue color("#FF269ff5") even when not focused/pressed.
Thank You.
you have to put the selector inside color/ and
<stroke
android:width="2dp"
android:color="#color/nameofcolor">
