I have a question concerning seekbars.
I tried several things but nothing helped.
I want to change the height of the seekbar, but not the complete seekbar, only the bar where you scroll over with your thumb. I tried several things e.g. setBackGroundDrawable and setProgressDrawable and made my own drawables, but the drawable-size is fixed to the size of the Standard-Android-Seekbar.
What can I do now?
You have to add some padding in all directions and than set the min and max height. Here are one example that I used:
<?xml version="1.0" encoding="utf-8"?>
<SeekBar xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:progressDrawable="#drawable/custom_player_seekbar_background"
android:paddingTop="10px"
android:paddingBottom="10px"
android:thumb="#drawable/bt_do_player"
android:paddingLeft="30px"
android:paddingRight="30px"
android:minHeight="6dip"
android:maxHeight="6dip"
android:layout_height="wrap_content"
android:layout_centerVertical="true"/>
For changing SeekBar size custom progressDrawable and custom thumb should be used. here is full implementation:
<SeekBar
android:layout_width="your desired width in dp"
android:layout_height="wrap_content"
android:minHeight="your desired height in dp"
android:maxHeight="as same as minHeight"
android:progressDrawable="#drawable/seekbar_drawable"
android:splitTrack="false"
android:thumb="#drawable/seekbar_thumb"
/>
===========================================================
create seekbar_drawable.xml file in res/drawable folder:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/seekbar_border" />
<item>
<clip android:drawable="#drawable/seekbar_progress"/>
</item>
</layer-list>
===========================================================
create seekbar_border.xml file in res/drawable folder:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="5dp" />
<solid android:color="#12000000" />
</shape>
===========================================================
create seekbar_progress.xml file in res/drawable folder:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="5dp" />
<solid android:color="#98F7DB" />
</shape>
===========================================================
and finally create seekbar_thumb.xml file in res/drawable folder:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#FF60C2A5" />
<size
android:width="your desired height in dp"
android:height="as same as width" />
</shape>

I have a gradient background with code:
<Button android:id="#+id/btn_signup"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Login"
android:background="#drawable/sel_btn_background"
android:gravity="center"
android:textSize="16sp"
android:layout_marginTop="40dp"
android:textColor="#android:color/white"/>
sel_btn_background.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="#color/bluegreen"
android:endColor="#color/aqua_marine"
android:angle="-270" />
</shape>
I get result:
How to achieve the below result(left side is the light colour fading to dark on right colour) What value should be added for angle:
Use 180 angle instead of -270 angle
android:angle="360"
It should be 360,Try the following:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="#36d1d1"
android:centerColor="#811010"
android:endColor="#233308"
android:angle="360" />
</shape>
Replace your color values accordingly.I have used completely different color distinguishing between all 3 colors.
try this...
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="#278b79"
android:centerColor="#32b39b"
android:endColor="#38c7ad"
android:angle="180" />
</shape>
I'm trying to add strokes to a view using drawable.
But I want add it only in side parts(left and right), not in whole parts.
Is there any good way to add stroke in side parts?
Below is my drawable xml code. (leanear_border_gray.xml)
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="2dp"
android:color="#778899"/>
</shape>
and below is my target view xml code.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#drawable/linear_border_gray"
android:layout_weight="1">
....
</LinearLayout>
You need to wrap your shape into layer-list drawable with rectangular shape, add stroke and using top and bottom margins with negative values "hide" top and bottom lines, like this:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:top="-4dp" android:bottom="-4dp">
<shape android:shape="rectangle">
<stroke android:width="2dp" android:color="#778899"/>
</shape>
</item>
</layer-list>
You can do it by using layer-list drawable suggested by #iDemigod
Your Layout should be like this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:orientation="vertical"
android:layout_marginTop="20dp"
android:background="#drawable/border_left_right"
android:layout_gravity="center"
android:layout_weight="1">
</LinearLayout>
Note: If you are giving android:layout_height="match_parent" and android:layout_weight="1" then you must have to set android:layout_width="0dp" and vice versa for android:layout_width="match_parent".
File: border_left_right.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:top="-4dp" android:bottom="-4dp">
<shape android:shape="rectangle">
<stroke android:width="2dp" android:color="#07060b"/>
</shape>
</item>
I'm trying to set my linearlayout background to a vector drawable, however it is not scaling to fill the entire layout, below is my xml:
<LinearLayout
android:id="#+id/ideaBody"
android:layout_width="220dp"
android:layout_height="229dp"
android:background="#drawable/ic_greenbackground"
android:orientation="horizontal"
android:scaleType="fitXY">
and the following is my vector xml;:
<vector android:height="500dp" android:viewportHeight="297.0"
android:viewportWidth="210.0" android:width="500dp" xmlns:android="http://schemas.android.com/apk/res/android">
<path android:fillAlpha="0.42" android:fillColor="#008000"
android:pathData="M1.14,40.02h58.21v60.59h-58.21z"
android:strokeAlpha="0.76" android:strokeWidth="0.26458332"/>
thank you
Why don't you try this if you want to set green background to your layout.
Change your XML code
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="#73008000" />
<stroke android:width="0.76dp" android:color="#BF008000" />
</shape>
</item>
</selector>
I'm a new to Android Development. While working on Android Studio 2.2, I tried to create a circular Button. As read from here, I tried to create a new Drawable Resource File. But I was unable to change Root Element to Shape. There was no such options. Could anyone help?
There are two solutions.
Floating Action Button: https://developer.android.com/reference/android/support/design/widget/FloatingActionButton.html
else:
You create a oval shape in xml.
and put that shape as background on button and make sure button have equal layout_height and layout_width.
Example:
oval_shape.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:dither="true"
android:shape="oval">
<solid android:color="#color/colorAccent"/>
</shape>
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="1">
<Button
android:layout_width="60dp"
android:layout_height="60dp"
android:background="#drawable/oval_shape"/>
</FrameLayout>
No option is needed here. Just use <shape>.
Check this example:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#color/colorPrimary" />
<corners android:radius="#dimen/btn_radius" />
</shape>
Use xml drawable like this:
Save the following contents as round_button.xml in drawable folder
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="false">
<shape android:shape="oval">
<solid android:color="#fa09ad"/>
</shape>
</item>
<item android:state_pressed="true">
<shape android:shape="oval">
<solid android:color="#c20586"/>
</shape>
</item>
And set it as background of Button in xml like this:
<Button
android:layout_width="50dp"
android:layout_height="50dp"
android:background="#drawable/round_button"
android:gravity="center_vertical|center_horizontal"
android:text="hello"
android:textColor="#fff" />
You are probably looking for the FloatingActionButton
It is available in the support-library.
The documation of the class.
i need to change android:color in XML file in run-time
i use it for an image button source
<ImageButton
android:layout_width="#dimen/large_brush"
android:layout_height="#dimen/large_brush"
android:background="#android:color/transparent"
android:contentDescription="#string/paint"
android:src="#drawable/paint"/>
my XML paint file looks like this
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval" >
<stroke
android:width="1dp"
android:color="#android:color/holo_purple" />
<gradient
android:startColor="#android:color/holo_purple"
android:endColor="#android:color/holo_purple" />
<corners android:radius="10dp" />
</shape>
</item>
</layer-list>
i tried DOM parser but after getting to gradient it shows that there are no more nodes
Try like this way. Hope it should helpful for you. Thanks
Create a new xml file and put it in drawable and then add it to button as background
gradient.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<!-- Gradient Bg for listrow -->
<gradient
android:startColor="#f1f1f2"
android:centerColor="#e7e7e8"
android:endColor="#cfcfcf"
android:angle="270" />
</shape>
layout.xml
<Button
android:id="#+id/Button1"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_weight="1"
android:background="#drawable/gradient"
android:text="Button Text" >
You have the background set to transparent, the button will never have a background. Set it to you XML drawabale resource instead.
