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

Android doesn't apply background color when a shape is defined

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" />

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.

custom (vertical) progress bar - doesn't match parent

I have vertical progress bar, here the xml defined in drawable folder :
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#android:id/background">
<shape>
<gradient
android:startColor="#ff9d9e9d"
android:centerColor="#ff5a5d5a"
android:centerY ="0.75"
android:endColor="#ff747674"
android:angle="180"
/>
</shape>
</item>
<item android:id="#android:id/secondaryProgress">
<clip android:clipOrientation="vertical" android:gravity="bottom">
<shape>
<gradient
android:startColor="#80ffd300"
android:centerColor="#80ffb600"
android:centerY="0.75"
android:endColor="#a0ffcb00"
android:angle="180"
/>
</shape>
</clip>
</item>
<item android:id="#android:id/progress">
<clip android:clipOrientation="vertical" android:gravity="bottom">
<shape>
<gradient
android:startColor="#ffffd300"
android:centerColor="#ffffb600"
android:centerY="0.75"
android:endColor="#ffffcb00"
android:angle="180"
/>
</shape>
</clip>
</item>
</layer-list>
and this I have add to styles.xml :
<style name="Widget"></style>
<style name="Widget.ProgressBar">
<item name="android:indeterminateOnly">true</item>
<item name="android:indeterminateBehavior">repeat</item>
<item name="android:indeterminateDuration">3500</item>
<item name="android:minWidth">48dip</item>
<item name="android:maxWidth">48dip</item>
<item name="android:minHeight">48dip</item>
<item name="android:maxHeight">480dip</item>
</style>
<style name="Widget.ProgressBar.Vertical">
<item name="android:indeterminateOnly">false</item>
<item name="android:progressDrawable">#drawable/vertical_progress_bar</item>
<item name="android:indeterminateDrawable">#android:drawable/progress_indeterminate_horizontal</item>
<item name="android:minWidth">1dip</item>
<item name="android:maxWidth">12dip</item>
</style>
When I'm using it :
<ProgressBar
android:id="#+id/vertical_progressbar"
style="#style/Widget.ProgressBar.Vertical"
android:layout_width="12dip"
android:layout_height="match_parent"
android:layout_marginRight="5dp"
the "match_parent"(the parent is item(row) in custom ListView) value has no effect and set the height as minHeigh, only explicit values can set height(Exmple:"100dip"),
also I have tried to set the value in my getView() method :
itemRow.vProgressBar.setMinimumHeight(convertView.getHeight());
it dosen't help, what is wrong? please help )
