how to set image button backgroundimage for different state?
I have the following declaring how a button should be drawn (uabutton.xml):
<?xml version="1.0" encoding="UTF-8"?>
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" >
<shape>
<corners
android:radius="3dp" />
<gradient
android:startColor="#000000"
android:endColor="#e9e8e9"
android:angle="270" />
</shape>
</item>
<item android:state_focused="true" >
<shape>
<corners
android:radius="3dp" />
<gradient
android:endColor="#ffffff"
android:startColor="#b9b9b9"
android:angle="270" />
</shape>
</item>
<item android:state_enabled="false">
<shape>
<corners
android:radius="3dp" />
<gradient
android:startColor="#f0aa9f"
android:endColor="#e21f00"
android:angle="270" />
</shape>
</item>
<item>
<shape>
<corners
android:radius="3dp" />
<gradient
android:startColor="#ff8a0e"
android:endColor="#e9e8e9"
android:angle="270" />
</shape>
</item>
</selector>
My question is, I would like to add an image to the background of each button. Where, if anywhere, in the above would I add the image.
The button is added a to a RelativeLayout:
<Button
android:id="#+id/aboutualocationbtn"
android:text="Menu"
android:layout_width="60dp"
android:layout_height="60dp"
android:background="#drawable/uabutton"/>

Wrap it in a Layer List drawable.

android:background="#drawable/uabutton"
is pointing to a file called uabutton in your drawables folder as the background
ie uabutton.jpg or uabutton.png

How to set progressbar background

I have set the progressbar style using the below code.
I have declared the progressbar widget:
<ProgressBar
android:id="#+id/loadProgress"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="20dip"
android:max="100"
android:progressDrawable="#drawable/load_progress"
android:progress="0" />
defined the "#drawable/load_progress"
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#android:id/background"
android:drawable="#drawable/background_bk">
</item>
<item
android:id="#android:id/progress"
android:drawable="#drawable/progress_bk">
</item>
</layer-list>
defined the "#drawable/background_bk" (it is red)
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<gradient
android:angle="0"
android:endColor="#ff0000"
android:startColor="#ff0990" />
<stroke
android:width="1dp"
android:color="#ff0000" />
</shape>
defined the #drawable/progress_bk (it is green)
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<gradient
android:angle="0"
android:endColor="#00ff00"
android:startColor="#00ff00" />
<stroke
android:width="1dp"
android:color="#00ff00" />
</shape>
The progressbar always shows totally green (which is how it should appear when the progress value is 100), even if I set the progress value to less than 100. Any input would be appreciated.
Here is what I did to have a progress bar that was green with clear background:
android:background="#color/white"
android:progressBackgroundTint="#color/white"
android:progressTint="#color/green_light"
Finally, I find a easy solution.
1
you can find the default drawable xml file in your folder
"SDK_path\platforms\android19\data\res\drawable"
Overthere you can find many default style of many widgets.
2
and get the file "progress_horizontal.xml".
the codes in that file is:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#android:id/background">
<shape>
<corners android:radius="5dip" />
<gradient
android:startColor="#ff9d9e9d"
android:centerColor="#ff5a5d5a"
android:centerY="0.75"
android:endColor="#ff747674"
android:angle="270"
/>
</shape>
</item>
<item android:id="#android:id/secondaryProgress">
<clip>
<shape>
<corners android:radius="5dip" />
<gradient
android:startColor="#80ffd300"
android:centerColor="#80ffb600"
android:centerY="0.75"
android:endColor="#a0ffcb00"
android:angle="270"
/>
</shape>
</clip>
</item>
<item android:id="#android:id/progress">
<clip>
<shape>
<corners android:radius="5dip" />
<gradient
android:startColor="#ffffd300"
android:centerColor="#ffffb600"
android:centerY="0.75"
android:endColor="#ffffcb00"
android:angle="270"
/>
</shape>
</clip>
</item>
</layer-list>

you can easily change the color of the "progress color" and "background color".

Determine default colour of background of Android buttons

How can I find the colour used for a default button's background, both when it is clicked and not. I've tried to use android.R.drawable.btn_default for not clicked, but this color is lighter then default on my tablet.
Then use custom color using selector eg customstyle.xml under drawable and using this as background for your button. Sample code its working fine for me.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" >
<shape>
<solid
android:color="#f8f9fa" />
<stroke
android:width="1dp"
android:color="#d2d2d2" />
<corners
android:radius="1dp" />
</shape>
</item>
<item>
<shape>
<gradient
android:startColor="#f8f9fa"
android:endColor="#d2d2d2"
android:angle="270" />
<stroke
android:width="1dp"
android:color="#d2d2d2" />
<corners
android:radius="1dp" />
</shape>
</item>
</selector>

I was trying to create a button similar in look to the round buttons over here -
http://livetools.uiparade.com/index.html
(every button looks like it is inside an immersed section) I had it by placing the button in a circle background and giving them both a little gradient that didnt end up the same though I got this result -
(I will upload my code once I can) how can I achieve that same look?
Try this code. I am able to produce an image that looks like this
which is similar to the first button you link to, using the following code. The key is to use <layer-list> to layer shapes one over the other to produce the desired effect.
File: res/drawable/button.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

In your main layout, add an ImageView that will display this image.
<ImageView
android:src="#drawable/button" />
You can make the ImageView clickable by giving it an OnClickListener in the Java code.

How to provide shadow to Button

As you can see in image, I want shadow behind a Button. I have created Button with rounded corners. But problem is I can't generate a shadow behind that Button. How can I achieve this?
Use this approach to get your desired look.
button_selector.xml :
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<layer-list>
<item android:right="5dp" android:top="5dp">
<shape>
<corners android:radius="3dp" />
<solid android:color="#D6D6D6" />
</shape>
</item>
<item android:bottom="2dp" android:left="2dp">
<shape>
<gradient android:angle="270"
android:endColor="#E2E2E2" android:startColor="#BABABA" />
<stroke android:width="1dp" android:color="#BABABA" />
<corners android:radius="4dp" />
<padding android:bottom="10dp" android:left="10dp"
android:right="10dp" android:top="10dp" />
</shape>
</item>
</layer-list>
</item>
</selector>
And in your xml layout:
<Button
android:background="#drawable/button_selector"
...
..
/>
For android version 5.0 & above
try the Elevation for other views..
android:elevation="10dp"
For Buttons,
android:stateListAnimator="#anim/button_state_list_animator"
button_state_list_animator.xml - https://android.googlesource.com/platform/frameworks/base/+/master/core/res/res/anim/button_state_list_anim_material.xml
below 5.0 version,
For all views,
android:background="#android:drawable/dialog_holo_light_frame"
My output:
Here is my button with shadow cw_button_shadow.xml inside drawable folder
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="false">

How to use. in Button xml, you can resize your height and weight
<Button
android:text="+ add friends"
android:layout_width="120dp"
android:layout_height="40dp"
android:background="#drawable/cw_button_shadow" />
If you are targeting pre-Lollipop devices, you can use Shadow-Layout, since it easy and you can use it in different kind of layouts.
Add shadow-layout to your Gradle file:
dependencies {
compile 'com.github.dmytrodanylyk.shadow-layout:library:1.0.1'
}
At the top the xml layout where you have your button, add to the top:
xmlns:app="http://schemas.android.com/apk/res-auto"
it will make available the custom attributes.
Then you put a shadow layout around you Button:
<com.dd.ShadowLayout
android:layout_marginTop="16dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:sl_shadowRadius="4dp"
app:sl_shadowColor="#AA000000"
app:sl_dx="0dp"
app:sl_dy="0dp"
app:sl_cornerRadius="56dp">
<YourButton
.... />
</com.dd.ShadowLayout>
You can then tweak the app: settings to match your required shadow.
Hope it helps.
I've tried the code from above and made my own shadow which is little bit closer to what I am trying to achieve. Maybe it will help others too.
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<layer-list>
<item android:left="5dp" android:top="5dp">
<shape>
<corners android:radius="3dp" />
<gradient
android:angle="315"
android:endColor="#android:color/transparent"
android:startColor="#android:color/black"
android:type="radial"
android:centerX="0.55"
android:centerY="0"
android:gradientRadius="300"/>
<padding android:bottom="1dp" android:left="0dp" android:right="3dp" android:top="0dp" />
</shape>
</item>
<item android:bottom="2dp" android:left="3dp">
<shape>
<corners android:radius="1dp" />
<solid android:color="#color/colorPrimary" />
</shape>
</item>
</layer-list>
</item>
</selector>
Try this if this works for you
android:background="#drawable/drop_shadow"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingLeft="3dp"
android:paddingTop="3dp"
android:paddingRight="4dp"
android:paddingBottom="5dp"
Sample 9 patch image with shadow
After a lots of research I found an easy method.
Create a 9 patch image and apply it as button or any other view's background.
You can create a 9 patch image with shadow using this website.
Put the 9 patch image in your drawable directory and apply it as the background for the button.
mButton.setBackground(ContextCompat.getDrawable(mContext, R.drawable.your_9_patch_image);
Since none of the answers here really address the question, I wanted to point out https://github.com/Devlight/ShadowLayout (not my project). This is a simple Android layout you can wrap around anything to give it a shadow. The library is a single class and only ~250 lines. The README says deprecated, but it works great.
Wrapping all your views isn't ideal, but until Android provides a standard mechanism to introduce a shadow, or you want to draw all of your button states as bitmaps that include the shadow pixels, this is the best option I could fine.
Adding the below 2 lines worked for me
android:elevation="10dp"
android:stateListAnimator="#null"
You can try this:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true">
<layer-list>
<item android:left="1dp" android:top="3dp">
<shape>
<solid android:color="#a5040d" />
<corners android:radius="3dip"/>
</shape>
</item>
</layer-list>
</item>
<item>
<layer-list>
<item android:left="0dp" android:top="0dp">
<shape>
<solid android:color="#99080d" />
<corners android:radius="3dip"/>
</shape>
</item>
<item android:bottom="3dp" android:right="2dp">
<shape>
<solid android:color="#a5040d" />
<corners android:radius="3dip"/>
</shape>
</item>
</layer-list>

Custom Buttons in Android: How to get border/edge/frame when I read the background from xml?

Using Android Shapes in xml I have defined a gradient which I use as the background for a button.
This all works nice, but there's no edge surrounding the button. I would like it to look similar to the normal Android button but I need more flexibility to control the color and look.
The shape is defined as follows:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient android:startColor="#FFFFFF"
android:endColor="#00FF00"
android:angle="270" />
<corners android:radius="3dp" />
<stroke android:width="5px" color="#000000" />
</shape>
I would expect the border to be set in the xml. Why doesn't "stroke" fix it? Stroke doesn't seem to do anything.
I checked the Android Developer spec, but couldn't find the answer there:
http://developer.android.com/guide/topics/resources/drawable-resource.html
I have also looked through all the properties of the Android Button, but as expected there's no such parameter, probably since it's built into the normal Android button. Btw, I checked ImageButton properties too.
Can someone please help?
I know there's the alternative to make an image with proper edges and use an ImageButton, but there really should be a way to fix this programmatically.
Thanks!

I had this problem a while ago. While I don't quite remember why I made each decision, the way I solved it was to use a a shape layer-list. This lets you stack one shape on top of another. For example, the following XML creates a shape with a solid black outline 2px wide, with a 'grey to white to grey' gradient across the middle:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<padding android:left="1dp"
android:top="1dp"
android:right="1dp"
android:bottom="1dp"/>
<solid android:color="#FF000000"/>
<corners android:radius="3dp"/>
</shape>
</item>
<item>
<shape>
<padding android:left="2dp"
android:top="2dp"
android:right="2dp"
android:bottom="2dp"/>
<gradient android:startColor="#FFB0B0B0"
android:centerColor="#FFFFFFFF"
android:endColor="#FFB0B0B0"
android:angle="315"/>
</shape>
</item>
</layer-list>
If you want to be able to change that color dynamically at runtime, then things get a lot messier. Again, the details of why I had to do things a certain way are hazy, but I ended up having to create a custom view class which contained a custom ShapeDrawable. I started off looking at the examples from the ApiDemos app which comes with the SDK - it's a very good resource.
EDIT: Another reason your stroke might not be appearing is that you forgot the android: before the color="...." bit.
I've had the same problem, what i observed is stroke is not applying to button as border at design time but at run time i see the border.
I jst used the following same code
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" android:padding="10dp">
<solid android:color="#color/black" />
<stroke android:width="1px" android:color="#color/red" />
</shape>
as steve hanley said abvoe you miss the android: for the color attribute.
Hope this helps somebody....
Probably much to late, but you have to add an extra ff before the color.
<stroke android:width="5px" color="#ff000000" />

Use ImageButton
<ImageButton
android:layout_width="40dp"
android:layout_height="30dp"
android:src="#drawable/left_arrow"
android:background="#drawable/button_selector"
android:gravity="center"/>
Use drawable selector to ImageButton and define your properties
<item android:state_pressed="true" >
<shape>
<gradient
android:startColor="#color/startColor"
android:endColor="#color/endColor"
android:angle="270" />
<stroke
android:width="0.5dp"
android:color="#color/borderColor" />
<corners
android:topLeftRadius="5dp"
android:bottomRightRadius="5dp"/>
</shape>
</item>
<item android:state_focused="true" >
<shape>
<gradient
android:startColor="#color/startColor"
android:endColor="#color/endColor"
android:angle="270" />
<stroke
android:width="0.5dp"
android:color="#color/borderColor" />
<corners
android:topLeftRadius="5dp"
android:bottomRightRadius="5dp"/>
</shape>
</item>
<item>
<shape>
<gradient
android:startColor="#color/startColor"
android:endColor="#color/endColor"
android:angle="270" />
<stroke
android:width="0.5dp"
android:color="#color/borderColor" />
<corners
android:topLeftRadius="5dp"
android:bottomRightRadius="5dp"/>
</shape>
</item>
<item android:state_enabled="false" android:drawable="#drawable/button_disabled" />
<item android:state_focused="true" android:drawable="#drawable/button_highlighted"/>
<item android:state_pressed="true" android:drawable="#drawable/button_highlighted"/>
<item>
<shape>
<gradient android:startColor="#fdfdfd" android:endColor="#f0f0f0" android:angle="270" />
<stroke android:width="1dp" android:color="#56390a" />
<corners android:radius="3dp" />
<padding android:left="10dp" android:top="10dp" android:right="10dp" android:bottom="10dp" />
</shape>
</item>
Adding stroke color #56390a will solve the problem.
