I've 6 button in my layout. All of it were using custom xml to make it rounded corner in android:background using single xml file. But now, how do I change the colour of every button programmatically? Since the android:background has been used.
here is the code.
1.Create a xml file in your drawable folder like mybutton.xml and paste the following markup:
<?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="#5e7974" />
<gradient android:angle="-90" android:startColor="#345953" android:endColor="#689a92" />
</shape>
</item>
<item android:state_focused="true">
<shape android:shape="rectangle" >
<corners android:radius="3dip" />
<stroke android:width="1dip" android:color="#5e7974" />
<solid android:color="#58857e"/>
</shape>
</item>
<item >
<shape android:shape="rectangle" >
<corners android:radius="3dip" />
<stroke android:width="1dip" android:color="#5e7974" />
<gradient android:angle="-90" android:startColor="#8dbab3" android:endColor="#58857e" />
</shape>
</item>
</selector>
2.Now use this drawable for the background of your view. If the view is button then something like this:
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:textColor="#ffffff"
android:background="#drawable/mybutton"
android:text="Buttons" />
And for colour change use style

I'm trying to achieve something like this in Android Studio:
I don't want the background shape to be as the TextView size, I want it half the size just like the above image. This is what I tried to do:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:bottom="30dp">
<shape android:shape="rectangle" >
<solid android:color="#f3f3f3" />
</shape>
</item>
<item android:top="20dp">
<shape android:shape="rectangle" >
<solid android:color="#FFC107" />
</shape>
</item>
</layer-list>
and it looks like this:
not exactly what I wanted. how can I do it like in the image above?
Try this:
define in a res/drawable new file called double_color.xml :
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/shape_rectangle">
<shape android:shape="rectangle" >
<solid android:color="#color/green" />
</shape>
</item>
<item android:top="-10dp" android:right="-10dp" android:left="-10dp">
<shape>
<solid android:color="#android:color/transparent" />
<stroke
android:width="10dp"
android:color="#android:color/white"/>
</shape>
</item>
</layer-list>
Than define a new style in res/values as:
<style name="TexViewStyle" parent="TextAppearance.AppCompat">
<item name="android:background">#drawable/double_color</item>
</style>
And last add style to your textView:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Full name"
style="#style/TexViewStyle"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
Will be like this:
enter image description here
They have little elevation effect and not outline box.
Just create an xml file in your drawable folder name as round_corner.xml.And add this following code.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="#color/darkGray" />
<corners android:radius="7dp" />
</shape>
</item>
<item
android:bottom="3dp"
android:right="3dp">
<shape android:shape="rectangle">
<solid android:color="#android:color/white" />
<corners android:radius="7dp" />
</shape>
</item>
</layer-list>
At Last you add this xml in background property of your Edittext as follows:-
<EditText
android:id="#+id/ed1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/round_corner"
/>
For some reason I can't manually resize any buttons on the design view using the handles. I can click and drag the handles but when I release, no changes are seen anywhere.
EDIT:
Here is the xml for the button:
<Button
android:text="√"
android:id="#+id/button15"
android:background="#drawable/operator_style"
android:textAllCaps="false"
android:fontFamily="sans-serif"
android:textSize="24sp"
android:textColor="#707070"
android:layout_alignBaseline="#+id/buttonLog"
android:layout_alignBottom="#+id/buttonLog"
android:layout_alignStart="#+id/button8"
android:elevation="0dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
And the linked background "operator_style" xml:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" >
<shape>
<solid
android:color="#00C7FC" />
<stroke
android:width="4dp"
android:color="#9FEDFF" />
<corners
android:radius="0dp" />
</shape>
</item>
<item>
<shape>
<solid
android:color="#cccccc" />
<corners
android:radius="0dp" />
<elevation
android:elevation="2dp" />
</shape>
</item>
</selector>
I have tried to get an image button of round shape. But it is displaying the circular image with a square shaped background but i need only the image without any background.
I also used round_image.XML as background drawable file but its not working.
menu.xml
<ImageButton
android:id="#+id/imageButton1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_centerHorizontal="true" android:src="#drawable/sliderr" android:background="#drawable/round_image"/>
round_image.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"android:shape="oval">
<gradient android:startColor="#50d050
android:endColor="#008000" android:angle="270"/>
<stroke
android:width="1px"
android:color="#000000"/>
</shape>
Use this corner , instead of yours
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#color/colorPrimary" />
<stroke android:color="#color/colorPrimary" />
<corners
android:bottomLeftRadius="5dp"
android:bottomRightRadius="5dp"
android:topLeftRadius="5dp"
android:topRightRadius="5dp" />
</shape>
I have a situation similar to this one, however, the method supposed there isn't working for me. I've tried different variation with tag but nothing has helped so far.
Here's my main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/hello" />
<SeekBar
android:id="#+id/seekBar1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:max="20"
android:progress="0"
android:secondaryProgress="0"
android:progressDrawable="#drawable/seekbar_progress" />
</LinearLayout>
drawable-mdpi/seekbar_progress.xml
<?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="#drawable/passive_progress">
<shape>
<corners android:radius="0dp" />
</shape>
</item>
<item
android:id="#android:id/progress"
android:drawable="#drawable/active_progress">
<clip>
<shape>
<corners android:radius="0dp" />
</shape>
</clip>
</item>
</layer-list>
Thank you.
