I have to create buttons styled like this:
Yes, strange I know. Those 2 corners should not scale if button text is shorter / longer.
Is this possible to create it using an XML ?
I tried a vector but the vector scales with the size of button.
Any other idea I have is to do it programmatically, e.g., something like in this answer
(Explanation of the design: we're experimenting with the design. Imagine button with 4 such corners. Buttons next to each other each having 2 corners close to the other one, etc. Our users love fancy design ... . :-) )
you can create customView
<LinearLayout
android:orientation="vertical"
android:layout_marginTop="100dp"
android:layout_marginLeft="100dp"
android:layout_width="100dp"
android:layout_height="wrap_content">
<View
android:layout_marginLeft="90dp"
android:background="#000000"
android:layout_width="match_parent"
android:layout_height="1dp"/>
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:gravity="center"
android:textSize="13dp"
android:textColor="#000000"
android:text="Button text.."
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="50dp" />
<RelativeLayout
android:layout_width="1dp"
android:layout_height="match_parent">
<View
android:background="#000000"
android:layout_width="1dp"
android:layout_height="10dp"/>
<View
android:layout_alignParentBottom="true"
android:background="#000000"
android:layout_width="1dp"
android:layout_height="10dp"/>
</RelativeLayout>
</LinearLayout>
<View
android:layout_marginLeft="90dp"
android:background="#000000"
android:layout_width="match_parent"
android:layout_height="1dp"/>
</LinearLayout>

Okay after a little research and best practice you surely need a Layerlist as a background for your Button(though even a TextView will work i.e it is also clickable like any view).
SOLUTION:
You will have to open the drawables folder and add a drawable resource called lets say custom_button_background then use this layerlist inside it:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<solid android:color="#000000" />
</shape>
</item>
<item android:top="20dp" android:bottom="20dp" android:left="20dp" android:right="20dp">
<shape>
<solid android:color="#ffffff" />
</shape>
</item>
<item android:right="80dp">
<shape>
<solid android:color="#ffffff" />
</shape>
</item>
<item android:top="80dp" android:bottom="80dp">
<shape>
<solid android:color="#ffffff" />
</shape>
</item>
</layer-list>
Then we are done! This will be our background, In my Android studio the Preview for this look like this:
You can adjust the values to reduce them to your needs. To set this as your Button or any View you simply add this attribute to it:
android:background="#drawable/custom_button_background"
Just adjust the measures to fit your Button Size!
I want to create a circular button in android. This the xml I am using:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#9F2200"/>
<stroke android:width="2dp" android:color="#fff" />
</shape>
Now when I put a button in the layout, I will have to set the above xml as the
android:background
attribute. But then how can I put an image within the circular button I have generated. How to accomplish this within the xml itself?
You can do this using FrameLayout
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5dp"
android:background="your selector" >
<Button
android:id="#+id/fbLogin"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="center"
android:background="yourimage"
android:gravity="center"/>
</FrameLayout>
If I got it you can use an ImageButton, which lets you choose both a background with android:background and a drawable resource with android:src.
Use an ImageButton and set your image with the src tag: android:src="#drawable/your_image"
I have a linearlayout background set to a drawable file in order to create that rounded corner look as such:
<LinearLayout
android:id="#+id/layout_top"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:background="#drawable/rectangle_topcorner">
<TextView android:layout_width="fill_parent"
android:id="#+id/textView1"
android:layout_height="wrap_content"
android:text="Impact"
android:layout_gravity="center"
android:textColor="#android:color/white"
android:layout_marginLeft="10dip" />
</LinearLayout>
In my adapter, after I inflate the layout item, I am trying to change the backgroundColor to a 'different' drawable, in order to change the background color:
LinearLayout top = (LinearLayout) view.findViewById(R.id.layout_top);
top.setBackgroundColor(R.drawable.rectangle_topcorner_high);
The problem is, after doing that, the rectangle loses its rounded corner look and its just a plain old square.
The 2 drawables:
rectangle_topcorner
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle"
android:id="#+id/background_shape" >
<corners android:topLeftRadius="30dp"
android:topRightRadius="30dp" />
<solid android:color="#005577"/>
</shape>
rectangle_topcorner_high
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle"
android:id="#+id/background_shape" >
<corners android:topLeftRadius="30dp"
android:topRightRadius="30dp" />
<solid android:color="#83162D"/>
</shape>
I'm missing something to preserve the rounded corners ?
Try using:
top.setBackgroundResource(R.drawable.rectangle_topcorner_high);
setBackgroundColor are for color resources
Thought I would share my eventual fix -
As I was trying variants of
top.setBackgroundColor(R.drawable.rectangle_topcorner_high);
The correct (working) code is:
top.setBackground(context.getResources().getDrawable(R.drawable.rectangle_topcorner_high));
I've read several thing about it but I can't find what I need.
I want to keep the grey arrow but I want to remove the horizontal bar from the default style and have a white background. Do you have any idea of how I can do this ?
Here is what I have now (default spinner style) :
Here is what I want :
I did a little modification based on #Mansur Khan 's answer.
We don't have to add an ImageView in this case because the spinner already has a triangle arrow. So check the code below:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="8dp"
android:background="#FFFFFF">
<Spinner
style="#style/Widget.AppCompat.DropDownItem.Spinner"
android:layout_width="match_parent"
android:layout_height="70dp"
android:id="#+id/sign_up_country"
/>
</RelativeLayout>

For the record, I found an easy solution : Wrap your spinner in a relative layout and add an image :
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/borderbottom_white"<!-- white background with bottom border -->
android:layout_marginTop="15dp" >
<Spinner
android:id="#+id/postfield_category"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="16sp"
android:background="#null"
android:minHeight="0dp" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:src="#drawable/arrowspinner" />
</RelativeLayout>
A simple solution that doesn't require you to create your own drawable for the arrow is to wrap the spinner with a RelativeLayout, and set the background color in the RelativeLayout, not the spinner:
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#f00" >
<Spinner
android:id="#+id/spinner1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
Use this:
yourspinner.setOnItemSelectedListener(this);
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
((TextView) yourspinner.getSelectedView()).setBackgroundColor(getResources()
.getColor(R.color.your_color));
}
and your class should implement OnItemSelectedListener.
Hi instead of wrapping Spinner component around Parent Layouts like LinearLayout, RelativeLayout etc which increases layout parsing simply create a drawable called spinner_bg.xml under drawable folder.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<bitmap
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="right"
android:src="#drawable/icn_dropdown_arw" />
</item>
</layer-list>
Set spinner_bg as the background of your spinner and it works like charm:
<Spinner
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="5dp"
android:background="#drawable/spinner_bg" />
I think the best way without doing complex layouts is this:
Use this xml for your spinner background and you are good to go!!!
<item android:state_pressed="true">
<shape>
<solid android:color="#color/materialBlueGray600" />
<corners android:radius="3dp" />
</shape>
</item>
<item android:state_selected="true">
<shape>
<solid android:color="#color/materialGray50" />
<corners android:radius="3dp" />
</shape>
</item>
<item>
<layer-list>
<item>
<shape>
<solid android:color="#color/materialGray50" />
<corners android:radius="3dp" />
</shape>
</item>
<item android:gravity="right">
<bitmap android:antialias="true" android:gravity="right" android:src="#drawable/ic_expand_small" />
</item>
</layer-list>
</item>
Here is the code of custom spinner. Please check it out and tell me. Not yet I tested this. So please inform me after checking this whether it solves your problem.
<Spinner
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/spinner_background"
android:gravity="center"
android:paddingRight="10dp"
android:spinnerMode="dropdown"
android:textColor="your text color"
android:textSize="your text size" />
Here is the drawable(spinner_background.xml) to create the background of spinner.
<?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="border color" />
<corners android:radius="3dp" />
</shape>
</item>
<item
android:bottom="1dp"
android:left="1dp"
android:right="1dp"
android:top="1dp">
<shape android:shape="rectangle" >
<solid android:color="#android:color/white" />
<corners android:radius="3dp" />
</shape>
</item>
</layer-list>
Edit:
please check this link which gives you an idea to do.
Customize spinner background
OR
you can do something like this.
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="spinner background image">
<Spinner
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#null"/>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:src="arrow image" />
</RelativeLayout>
below layout will create a background in spinner with desire color drop down arrow
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight=".6"
android:background="#drawable/edit_text_rounded_shape"
android:gravity="center|center_vertical">
<Spinner
android:id="#+id/spinerComanyName"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:padding="4dp"
android:layout_weight=".6"
android:layout_gravity="center"
android:entries="#array/spinner_item"
android:spinnerMode="dropdown"
android:theme="#style/Spinner"
/>
</LinearLayout>
<style name="Spinner">
<!-- Used for the bottom line when not selected / focused -->
<item name="colorControlNormal">#color/black</item>
<item name="colorControlActivated">#color/colorPrimary</item>
<!-- colorControlActivated & colorControlHighlight use the colorAccent color by default -->
</style>
edit_text_rounded_shape which provide background color and rounded corner
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" android:padding="10dp">
<solid android:color="#color/white"/>
<stroke android:color="#color/grey"/>
<corners
android:bottomRightRadius="15dp"
android:bottomLeftRadius="15dp"
android:topLeftRadius="15dp"
android:topRightRadius="15dp"/>
</shape>
A good way to customise spinners and any other Android controls is to use the Android Asset Studio site and choose the Android Holo Colors Generator. This will create all the assets you might need, including the "underline". It also generates the XML files that implement the changes.
Once you download the ZIP file from that site, you just copy the images and XML files into your project.
You can then edit the required image files to remove the underline. They are 9-Patch files, called:
apptheme_spinner_default_holo_light.9.png
apptheme_spinner_disabled_holo_light.9.png
apptheme_spinner_focused_holo_light.9.png
apptheme_spinner_pressed_holo_light.9.png
For a more complete explanation of the process, and to see some of the sample XML files, please refer to my related answer:
Change colour of small triangle on spinner in android
android:layout_alignParentRight="true"
android:layout_width="#dimen/spinner_width"
android:layout_height="wrap_content"
android:id="#+id/spnLocation"
android:entries="#array/labelFamily"
android:layout_centerVertical="true"
android:backgroundTint="#color/color_gray"
this work for me
Always while working with spinners, buttons and EditTexts and also needing to insert a drawable, I often wrap the element (spinner, EditText etc.) in a FrameLayout. Check an example:
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Spinner
android:id="#+id/spinner_component"
android:layout_width="match_parent"
android:layout_height="45dp"
android:background="#drawable/your_rectangle_style"
android:textColor="#color/your_text_color" />
<ImageView
android:layout_width="11dp"
android:layout_height="9dp"
android:src="#drawable/arrow_spinner"
android:layout_gravity="right|center_vertical"
android:layout_marginRight="7dp" />
</FrameLayout>
Another important tip is that FrameLayout allows you to set OnClick functions on the drawable, for instance.
I am trying to get a TextView with white background and rounded corners and text in the middle.
Something that looks like this:
So far I have this but it is not giving me the above effect.
<TextView
android:textColor="#000000"
android:background="#FFFFFF"
android:text="0" />
First of all, I would create a custom drawable resource for easy implementation of rounded corners.
(place this in res/drawable)
my_bg.xml:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid
android:color="ffffff" />
<corners
android:radius="15dp"/>
<stroke
android:width="1dp"
android:color="#android:color/black" />
</shape>
More info on xml drawable resources can be found right here if you want to get into more advanced drawables (gradients, layer-list, animation, etc...)
Then change your TextView in xml layout file to match this:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="8dp"
android:textColor="#000000"
<!--refer to your custom drawable from earlier-->
android:background="#drawable/my_bg"
<!--center text within TextView-->
android:gravity="center"
android:text="0" />
I hope this helps, Happy Coding!
Set the gravity
android:gravity="center"
http://developer.android.com/reference/android/widget/TextView.html#attr_android:gravity
You are missing the width and height attribute for TextView.
For the rounded corners use a Shape Drawable
http://developer.android.com/guide/topics/resources/drawable-resource.html#Shape
Under res/drawable
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle"
>
<solid android:color="#FFFFFF"/>
<corners android:radius="7dp" />
<stroke android:width="5px" />
</shape>
Then
<TextView
android:layout_width="100dp"
android:layout_height="50dp"
android:background="#drawable/background"
android:gravity="center"
android:text="0"
android:textColor="#000000" />
