How do I add custom button in Android Studio 2.2?
I found info that I have to:
make an .xml file in app/src/main/res/drawable (for example custom_button.xml):
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/button_on"
android:state_pressed="true" />
<item android:drawable="#drawable/button_focused"
android:state_focused="true" />
<item android:drawable="#drawable/button_off" />
</selector>
add my .png images (button_on, button_off, button_focused) to app/src/main/res/drawable-xxhdpi (I do not have this folder - I placed images in drawable folder - making xxhdpi folder by myself and placing images there doesn't work either)
edit activity_main.xml:
<Button
android:text=""
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/button_microphone"
android:layout_alignBaseline="#+id/button_add_resource"
android:layout_alignBottom="#+id/button_add_resource"
android:layout_centerHorizontal="true"
android:background="#drawable/custom_button"/>
And now what? It doesn't work, although the button shows up in activity_main.xml visualiser.
Errors:
Solved.
I just forgot to use Android\sdk\tools\sdraw9patch.bat to make 1 pixel width borders on my images.

<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
android:orientation="vertical"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="ImageButton Selected"/>
<Button
android:id="#+id/btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/button"/>
This is in my activity_main.xml
and this
<item android:drawable="#drawable/round" android:state_pressed="true"/>
<item android:drawable="#drawable/round2" android:state_focused="true"/>
in my button.xml
the custom buttons are made with image button function
when I start the application It doesn't give error and shows only "imagebutton selected"
The problem can be with my image?being too large?
here are the images and they are png btw with 1000x1000..I know is big but being png I thought will be everything fine..now I have to find how to make the white background dissapear.
here are the images round and round2
I don't know what is a selector,I know that I've put them in the folder drawable and then I followed a tutorial to make custom buttons.
the images are vectors
here is how the emulator looks like emulator
Your button.xml should look like this.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- pressed -->
<item android:drawable="#drawable/round2" android:state_pressed="true"/>
<!-- focused -->
<item android:drawable="#drawable/round3" android:state_focused="true"/>
<!-- default -->
<item android:drawable="#drawable/round"/>
</selector>
Also, you should reduce the size of your PNGs, that would take up a lot of space, and a lot of memory.
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.

Thanks in Advance!
use 9-patch images for selector images. this will help Android to stretch your images as you described in your 9-patch boundaries
Draw 9-patch
Draw 9-patch Tutorial
Another Android 9 Patch Image Tutorial
Use the draw9patch application found in android-sdk/tools. Check instructions how it works and backgrounds should be able to scale properly.
I'm trying to give a custom background to my spinner. I've downloaded the HTC sense spinner design (Cf. following pictures) with the 9 patch format.
I've created a new XML file with the following code inside:
<?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="false"
android:drawable="#drawable/spinner_pressed" />
<item
android:state_focused="true"
android:state_pressed="true"
android:drawable="#drawable/spinner_pressed" />
<item
android:state_focused="false"
android:state_pressed="true"
android:drawable="#drawable/spinner_pressed" />
<item
android:drawable="#drawable/spinner_normal" />
</selector>
And I've added a spinner to my layout with this code:
<Spinner
android:id="#+id/my_spinner"
android:layout_width="180dp"
android:layout_height="50dp"
android:layout_marginLeft="20dp"
android:background="#drawable/custom_spinner" />
But whereas being correctly displayed, I got the following format:
Did I make something wrong?
I hope you'll can help me.

The stretchable areas defined on your 9-patch seem wrong, and that is why your 9-patch are stretched like this. Have a look at Nine-patch docs and notice that the left-border defines what area should be stretched. I think you should also define a stretchable area below the "arrow" if you want the "arrow" to be centered.
If you do not know how to edit 9-patch you should use draw9patch it is included in the AndroidSDK/tools.
My imagebutton code wont respond to "fill_parent" and "wrap_content".
Instead, it just shows the middle of the image (because it is a pretty big image).
I tried setting specific values for the image but it still didn't work! Can somebody help me?
My button.xml in the res/drawable folder:
<?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/largishbutton" /> <!-- pressed -->
<item android:state_focused="true"
android:drawable="#drawable/largerbutton2" /> <!-- focused -->
<item android:drawable="#drawable/largerbutton" /> <!-- default -->
</selector>
My main.xml in the res/layout folder:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#android:color/white">
<ImageButton
android:src="#drawable/button"
android:layout_height="fill_parent"
android:layout_width="wrap_content"
/>
</RelativeLayout>
I tried using a LinearLayout, but the app wouldnt run, and I tried replacing the imagebutton with an imageview, but then the button didn't work.
If your image is bigger than your button, you will need to use something like android:scaleType or setMaxHeight() to have it resize to fit.
Also, I recommend that you have all images in your <selector> be the same size, at least until you get things working the way you wish.
