<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="true" android:drawable="#drawable/forwardpress"></item>
<item android:state_focused="true" android:drawable="#drawable/forwardhover"></item>
<item android:drawable="#drawable/forward"></item>
</selector>

<item android:drawable="#drawable/forward"/>
</selector>

Clean and build your project again.

I am trying to customize a Button UI in Android.
I tried the following things:
btn.setBackgroundColor
btn.setBackgroundResource
btn.setBackgroundColor
But all of these are increasing the size of the Button, and because of that the Buttons near by can not be segregated (??).
Please suggest something.
If you want to apply a Hover effect then you have to do this in your XML where button layout is like
Button
android:id="#+id/xyz"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_marginTop="15dp"
android:background="#drawable/general_btn_hover_effect"
android:onClick="somefunction"
android:text="#string/search_number"
android:textColor="#ffffff"
android:textSize="20sp"
/>
Notice android:background="#drawable/general_btn_hover_effect" there and then in #drawable folder make a general_btn_hover_effect.xml and write this into it
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/blank_normal_bg" android:state_focused="true" android:state_pressed="false"/>
<item android:drawable="#drawable/blank_hover_bg" android:state_focused="true" android:state_pressed="true"/>
<item android:drawable="#drawable/blank_hover_bg" android:state_focused="false" android:state_pressed="true"/>
<item android:drawable="#drawable/blank_normal_bg"/>
</selector>
Changing background color can not change size of button. Maybe you changed size in xml layout. Check again
I my app i have many buttons,what i want is that when user selects particular button,its background should change so that user knows which button is selected.So for this i have used selectors.But when ever i run my app the event on button click works fine but the button image doesnt change
Selector
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/people_1" android:state_selected="true"></item>
<item android:drawable="#drawable/people_1" android:state_active="true"></item>
<item android:drawable="#drawable/places_1" android:state_focused="true"></item>
<item android:drawable="#drawable/hotel_icon"></item>
</selector>
Xml where i used the selector
<Button
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/hotel"
android:layout_weight="1"
android:id="#+id/home" />
I solved it,the only thing missing was
<item android:drawable="#drawable/selected" android:state_pressed="true" />
I've been trying to customize the toggle button look but with no success.
Here is how I want it to look like:
Can someone give me a tutorial?
create toggle_selector.xml in res/drawable
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/toggle_on" android:state_checked="true"/>
<item android:drawable="#drawable/toggle_off" android:state_checked="false"/>
</selector>
apply the selector to your toggle button
<ToggleButton
android:id="#+id/chkState"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/toggle_selector"
android:textOff=""
android:textOn=""/>
Note: for removing the text i used following in above code
textOff=""
textOn=""
I don't know if this is the best solution but it worked fine for me:
1.- Decide how big do you want the toggle button. In my case width 56dp and height 76dp.
2.- Create the icon set 56px-76px for mdpi, 84px-113px hdpi, same for xhdpi and xxhdpi
3.- Move the icons in the corresponding drawable folder. In my case 20 icons 5 in each folder, named ic_name1_on, ic_name1_off [...] ic_name5_off
4.- Create the following xml files in a new folder called drawable (if it does not exist yet):
ic_name1_toggle.xml
ic_name1_toggle_bg.xml
ic_name2_toggle.xml
(...)
ic_name5_toggle_bg.xml
5.- In ic_name1_toggle.xml the code must be:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_checked="false"
android:drawable="#drawable/ic_name1_off" />
<item
android:state_checked="true"
android:drawable="#drawable/ic_name1_on" />
</selector>
6.- In ic_name1_toggle_bg.xml the code must be:
<?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="#android:color/transparent" />
<item android:id="#+android:id/toggle"
android:drawable="#drawable/ic_name1_toggle" />
</layer-list>
7.- Finally in your layout.xml:
<ToggleButton
android:id="#+id/toggleButton1"
android:layout_width="56dp"
android:layout_height="76dp"
android:background="#android:color/transparent"
android:button="#drawable/ic_name1_toggle_bg"
android:textOff=""
android:textOn="" />
I think you need to define a custom background for your button.
Take a look at the Developer Guide on customizing a Button's background.
However, in step Three, Create a new XML file in the res/drawable/ directory Use this Xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/button_da"
android:state_checked="true" />
<item android:drawable="#drawable/button_nu" />
</selector>
The element android:state_checked="true" is what defines that state as the checked background.
Let me know if this works for you.
Create selector
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/btn_da" android:state_checked="true"/>
<item android:drawable="#drawable/btn_nu"/>
</selector>
and use it as background for your ToggleButton.
I have created image buttons instead of normal buttons.On click on the image button I want a click effect as in the normal icon click effect(On click of menu the background of the icon will be yellow color) of android phones.Using the following code I code show an image on click of the image button .What changes I have to make further.
<item android:state_enabled="true"
android:state_pressed="true"
android:drawable="#drawable/production_order" />
android:state_enabled="false"
android:drawable="#drawable/prodution_orders_icon" />
Try this code
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" android:drawable="#drawable/camera" />
<item android:state_pressed="false" android:drawable="#drawable/camera" />
<item android:state_pressed="true" android:drawable="#drawable/camera_active" />
</selector>
Instead of using directly ImageButton you can use Button with customized background
Here is the sample tutorial.
create xml file using the button image like this
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_pressed="true"
android:drawable="#color/transparent" />
<item
android:drawable="#drawable/closebutton" />
</selector>
add the color folder in values
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="yellow">#ffffff00</color>
</resources>
I want that in my android application, the ImageButton change its image when it is pressed and released, and when it is pressed released again, the image for ImageButton will be changed back , how to do that?
I have tried it with selector.
But it is not working.
Please anyone help me.
Thanks
make file in drawable folder a.xml ::
