i am converting one of my android apps into titanium alloy, I have some selector xml for buttons which are kept in res/drawable folder(custom_btn_genoa.xml), shown below:
<?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="3dip" />
<stroke android:width="1dip" android:color="#20534e" />
<gradient android:angle="-90" android:startColor="#062d30" android:endColor="#4c898e" />
</shape>
</item>
<item android:state_focused="true">
<shape android:shape="rectangle" >
<corners android:radius="3dip" />
<stroke android:width="1dip" android:color="#20534e" />
<solid android:color="#125156"/>
</shape>
</item>
<item >
<shape android:shape="rectangle" >
<corners android:radius="3dip" />
<stroke android:width="1dip" android:color="#20534e" />
<gradient android:angle="-90" android:startColor="#4c898e" android:endColor="#125156" />
</shape>
</item>
</selector>
Then my buttons styles (values/styles.xml)
<style name="btnStyleGenoa" parent="#android:style/Widget.Button">
<item name="android:textSize">15sp</item>
<item name="android:textStyle">bold</item>
<item name="android:textColor">#FFFFFF</item>
<item name="android:gravity">center</item>
<item name="android:shadowColor">#000000</item>
<item name="android:shadowDx">1</item>
<item name="android:shadowDy">1</item>
<item name="android:shadowRadius">0.6</item>
<item name="android:background">#drawable/custom_btn_genoa</item>
<item name="android:padding">10dip</item>
</style>
In titanium i can set the textsize, color, and so forth, but how can i implement the selector xml stuff in titanium alloy easily?
The conversion from Android styles to Titanium is not one to one, it is meant to be generally applicable to multiple platforms (iOS, Android, Windows, Blackberry). In this case (if you are trying to emulate a button selector) this is built in to Titanium, here is an approximation of the selector to Alloy xml for what you have:
<Alloy>
<Button id="button" title="Hello"
top="10" width="100" height="50"
color="#FFF"
backgroundFocusedColor="#125156"
backgroundColor="#125156"
backgroundSelectedColor="#4c898e"/>
</Alloy>
The backgroundFocused and Selected each specify different images or colors to use when a user interacts with the button.

I want to change the style of the Button. And I add the style in style.xml then set the #style/BaseButton to every Button.
Is there any way can do it better? Can I just set the theme to change all Button or other views?
I know that I can add the theme to the style.xml but unfortunately, if I set the attributes like #android:background to the Button, other views' backgrounds are set too.
So here are what I need:
Set the style in only one(or some) place(s). No need to set style in
every layout and every <Button />.
Only the Button is influenced while other views stay where they
are.
Can be changed easily.
Follow below steps
Create an XML file that represents the button states
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_enabled="false"
android:drawable="#drawable/button_disabled" />
<item
android:state_pressed="true"
android:state_enabled="true"
android:drawable="#drawable/button_pressed" />
<item
android:state_focused="true"
android:state_enabled="true"
android:drawable="#drawable/button_focused" />
<item
android:state_enabled="true"
android:drawable="#drawable/button_enabled" />
</selector>
Create an XML file that represents each button state
First button shape is for the enabled button state.
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<gradient
android:startColor="#00CCFF"
android:centerColor="#0000CC"
android:endColor="#00CCFF"
android:angle="90"/>
<padding android:left="7dp"
android:top="7dp"
android:right="7dp"
android:bottom="7dp" />
<stroke
android:width="2dip"
android:color="#FFFFFF" />
<corners android:radius= "8dp" />
</shape>
Second button shape is for the focused button state.
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<gradient
android:startColor="#F7D358"
android:centerColor="#DF7401"
android:endColor="#F7D358"
android:angle="90"/>
<padding android:left="7dp"
android:top="7dp"
android:right="7dp"
android:bottom="7dp" />
<stroke
android:width="2dip"
android:color="#FFFFFF" />
<corners android:radius= "8dp" />
</shape>
Third button shape is for the pressed button state.
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<gradient
android:startColor="#0000CC"
android:centerColor="#00CCFF"
android:endColor="#0000CC"
android:angle="90"/>
<padding android:left="7dp"
android:top="7dp"
android:right="7dp"
android:bottom="7dp" />
<stroke
android:width="2dip"
android:color="#FFFFFF" />
<corners android:radius= "8dp" />
</shape>
And finally, Fourth button shape is for the disabled button state.
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<gradient
android:startColor="#F2F2F2"
android:centerColor="#A4A4A4"
android:endColor="#F2F2F2"
android:angle="90"/>
<padding android:left="7dp"
android:top="7dp"
android:right="7dp"
android:bottom="7dp" />
<stroke
android:width="2dip"
android:color="#FFFFFF" />
<corners android:radius= "8dp" />
</shape>
Create an XML file that represents the button style
<resources>
<style name="button" parent="#android:style/Widget.Button">
<item name="android:gravity">center_vertical|center_horizontal</item>
<item name="android:textColor">#FFFFFFFF</item>
<item name="android:shadowColor">#FF000000</item>
<item name="android:shadowDx">0</item>
<item name="android:shadowDy">-1</item>
<item name="android:shadowRadius">0.2</item>
<item name="android:textSize">16dip</item>
<item name="android:textStyle">bold</item>
<item name="android:background">#drawable/button</item>
<item name="android:focusable">true</item>
<item name="android:clickable">true</item>
</style>
Create an XML with your own custom application theme .themes.xml below
<resources>
<style name="YourApplicationTheme" parent="android:style/Theme.NoTitleBar">
<item name="android:buttonStyle">#style/button</item>
</style>
</resources>
Now, you can create buttons on your application with the new style
Use this
<style name="ApplicationStyle" parent="android:Theme">
<item name="android:buttonStyle">#style/CKButton</item>
</style>

How do I apply a style to all buttons of an Android application
I'm trying to create a style for buttons in my app. In order to do that, I created a drawable file with the corner tag. I also created different styles for different button state (normal and disabled). When I apply the style without setting the background attribute, the button have the correct color. But when I set the background attribute with my drawable file, the text color defined in the style.xml works but not the background color. Here is the code :
values/style.xml :
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:background">#color/background</item>
<item name="android:textColor">#color/text_color</item>
</style>
<style name="ButtonStyle">
<item name="android:background">#color/button_color</item>
</style>
<style name="ButtonDisableStyle">
<item name="android:background">#color/button_color_disabled</item>
<item name="android:textColor">#color/buttonText_color_disabled</item>
</style>
drawable/button_shape.xml :
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
<corners
android:radius="5dp" />
<padding
android:left="0dp"
android:top="0dp"
android:right="0dp"
android:bottom="0dp" />
</shape>
main_activity :
<Button
android:id="#+id/newButton"
android:text="#string/generate_first"
style="#style/ButtonStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight="30"
android:background="#drawable/button_shape"
/>
I saw several post about the same problem and I know that it is possible to define the button's background color in the drawable/button_shape.xml but I'd like to keep the style and make it works (I want the shape and the style to be separated).
Do you have any idea about it ?
Finally and after more research, I found a solution. I created 3 xml shape files for the button corresponding to 3 different states. Then I created a 4th xml shape file which includes the 3 others.
Finally, I put a reference to the 4th shape xml file into the button style (in values/style.xml). Here is the code :
drawable/button_disabled.xml :
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<solid android:color="#color/buttonText_color_disabled"/>
<padding android:left="7dp"
android:top="7dp"
android:right="7dp"
android:bottom="7dp" />
<corners android:radius= "5dp" />
</shape>
drawable/button_pressed.xml :
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<solid android:color="#color/button_color_pressed"/>
<padding android:left="7dp"
android:top="7dp"
android:right="7dp"
android:bottom="7dp" />
<corners android:radius= "5dp" />
</shape>
drawable/button_enabled.xml:
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<solid android:color="#color/button_color"/>
<padding android:left="7dp"
android:top="7dp"
android:right="7dp"
android:bottom="7dp" />
<corners android:radius= "5dp" />
</shape>
drawable/button.xml :
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_enabled="false"
android:drawable="#drawable/button_disabled" />
<item
android:state_pressed="true"
android:state_enabled="true"
android:drawable="#drawable/button_pressed" />
<item
android:state_enabled="true"
android:drawable="#drawable/button_enabled" />
</selector>
values/style.xml :
<style name="Custom_button" parent="#android:style/Widget.Button">
<item name="android:gravity">center_vertical|center_horizontal</item>
<item name="android:textColor">#color/text_color</item>
<item name="android:textSize">16dip</item>
<item name="android:textStyle">bold</item>
<item name="android:background">#drawable/button</item>
<item name="android:clickable">true</item>
</style>
main_activity :
<Button
android:id="#+id/newButton"
android:text="#string/generate_first"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_below="#id/app_info"
android:layout_centerHorizontal="true"
android:layout_marginTop="35dp"
android:layout_marginBottom="50dp"
style="#style/Custom_button" />
How can I make a style file that adds borders to all buttons? All buttons already have a background image.
Create your style in file res/values/styles.xml
<style name="KeyBoardButton">
<item name="android:layout_width">0dp</item>
<item name="android:layout_height">match_parent</item>
<item name="android:layout_weight">1</item>
<item name="android:gravity">center</item>
<item name="android:layout_margin">4dp</item>
<item name="android:paddingTop">8dp</item>
<item name="android:paddingBottom">8dp</item>
<item name="android:textAppearance">?android:attr/textAppearanceMedium</item>
<item name="android:textColor">#555</item>
<item name="android:background">#drawable/button_border</item>
</style>
Define the border that will be used in file res/drawable/button_border.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true">
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners
android:radius="4dp"/>
<solid
android:color="#d5cbc6" />
<stroke
android:width="2dp"
android:color="#dedede" />
</shape>
</item>
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners
android:radius="4dp"/>
<solid
android:color="#f9f9f9" />
<stroke
android:width="2dp"
android:color="#dedede" />
</shape>
</item>
Now you can use it in your layout files, as follows:
<Button android:id="#+id/my_button"
style="#style/KeyBoardButton"
android:text="1" />
I have this style on my styles.xml:
<style name="btnStyleGenoa" parent="#android:style/Widget.Button">
<item name="android:textSize">15sp</item>
<item name="android:textStyle">bold</item>
<item name="android:textColor">#FFFFFF</item>
<item name="android:gravity">center</item>
<item name="android:shadowColor">#000000</item>
<item name="android:shadowDx">1</item>
<item name="android:shadowDy">1</item>
<item name="android:shadowRadius">0.6</item>
<item name="android:background">#drawable/custom_btn_genoa</item>
<item name="android:padding">10dip</item>
</style>
I also have this custom_btn_genoa.xml on 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="3dip" />
<stroke android:width="1dip" android:color="#20534e" />
<gradient android:angle="-90" android:startColor="#062d30" android:endColor="#4c898e" />
</shape>
</item>
<item android:state_focused="true">
<shape android:shape="rectangle" >
<corners android:radius="3dip" />
<stroke android:width="1dip" android:color="#20534e" />
<solid android:color="#125156"/>
</shape>
</item>
<item >
<shape android:shape="rectangle" >
<corners android:radius="3dip" />
<stroke android:width="1dip" android:color="#20534e" />
<gradient android:angle="-90" android:startColor="#4c898e" android:endColor="#125156" />
</shape>
</item>
</selector>
Finally, i have this button:
<Button
android:text="#string/change_but"
android:textSize="15dp"
android:layout_width="100dp"
android:layout_height="wrap_content"
android:layout_marginRight="30dp"
android:id="#+id/change_but"
android:onClick="onChangeClicked"
style=”#style/btnStyleGenoa”
/>
The button does not use the desired style. Last line in button (style) says "attribute value expected. Any thoughts?
(Note, i found this code on a website, it's not mine)
You must replace style=”#style/btnStyleGenoa” to style="#style/btnStyleGenoa"
Working like a charm.
I am creating a custom style for a seek bar using xml:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#android:id/background">
<shape>
<solid android:color="#00FF00" />
<corners android:radius="0dp" />
</shape>
</item>
<item android:id="#android:id/progress">
<clip>
<shape>
<solid android:color="#FF0000" />
<corners android:radius="0dp" />
</shape>
</clip>
</item>
</layer-list>
<style name="Widget.MySeekBar" parent="android:Widget.SeekBar">
<item name="android:indeterminateOnly">false</item>
<item name="android:progressDrawable">#drawable/seek_bar_progress</item>
<item name="android:minHeight">3dp</item>
<item name="android:maxHeight">3dp</item>
<item name="android:thumb">#drawable/image_seek_bar_thumb</item>
<item name="android:thumbOffset">8dp</item>
<item name="android:focusable">true</item>
</style>
I want the background to be thinner than the progress similar to the standard jelly bean style seek bars. Is there any way to do this?
Thanks
I have used this in xml:
<SeekBar
android:id="#+id/seekID"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/linearLayoutComponentTopRow"
android:layout_marginTop="1px"
android:background="#drawable/slide_bar"
android:progress="0"
android:secondaryProgress="0"
android:thumb="#drawable/bt_slider" />
It sets the background and the thumbnail too.
I hope it helps!
