How to make a Custom Button with XML Files?

Since I followed a Video from "Coding in Flow", I did everything (Link: https://www.youtube.com/watch?v=Z1w3y0saKjY)
And of course, I like to add Custom Buttons into my Game. But the Problem is, that the View shows still the standard button or doesn't even like me (that won't even show in preview). And my laptop doesn't have that much space available, then I can't run on AVD Device. And I'll do the first tests on my 25% development completion.
Still, nothing. This is the code (all 5 codes including styles.xml):
<?xml version="1.0" encoding="utf-8"?>
<!--button_default.xml-->

I hope for any answer. It could be the case of "AndroidX" thing.

Android: custom seekbar thumb doesn't show correctly

I have a custom SeekBar with a specific style:
<SeekBar
android:id="#+id/mediacontroller_progress"
style="#style/MediaSeekBar"
android:layout_width="0dip"
android:layout_weight="1"
android:layout_height="wrap_content" />
MediaSeekBar style:
<style name="MediaSeekBar" parent="android:Widget.SeekBar">
<item name="android:progressDrawable">#drawable/media_seek_bar</item>
<item name="android:minHeight">2dp</item>
<item name="android:maxHeight">2dp</item>
<item name="android:thumb">#drawable/media_seek_bar_thumb</item>
<item name="android:progress">0</item>
</style>
media_seek_bar drawable:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#android:id/background">
<shape>
<corners android:radius="0dip" />
<solid android:color="#20ffffff" />
</shape>
</item>
<item android:id="#android:id/secondaryProgress">
<clip>
<shape>
<corners android:radius="0dip" />
<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="0dip" />
<solid android:color="#color/theme_accent_1" />
</shape>
</clip>
</item>
</layer-list>
media_seek_bar_thumb drawable:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:drawable="#drawable/control_pressed" />
<item android:state_focused="true"
android:drawable="#drawable/control_pressed" />
<item android:state_selected="true"
android:drawable="#drawable/control_pressed" />
<item android:drawable="#drawable/control_normal" />
</selector>
And the result:
without press
when I press thumb
So the problem is the area arround the yellow circle: it's translucent in my png files but not in App.

Problem is in your images inside selector. Probably images have extra space. I have tried to run your code with custom drawable inside selector and it works fine. Here my circle drawable:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#ffe600"/>
<size
android:width="15dp"
android:height="15dp"/>
</shape>

<SeekBar
android:splitTrack="false"
....
/>
Will be ok.

just set this code and work
android:thumbTint="#android:color/transparent" // this code for hide thumb
android:splitTrack="false" // this code for show correctly

Style file to add border to all buttons?

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" />

Android custom button style not working

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.

Android seek bar with skinny background

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!
