How to merge an edittext with spinner in Android?

How can I make an EditText with a drop-down in Android?
For reference i have added an image. I am trying to combine an edittext with spinner but I am not able to achieve the same.
Can anyone add suggestion or xml mockup?

Well, You can use a LinearLayout with a horizontal orientation and create a custom drawable for the rounded border.
Implementation
First, you need to draw the rounded border by creating a new Drawable resource file.
In your res/drawables folder create rounded_border.xml
rounded_border.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<corners android:radius="4dp" />
<stroke android:width="2dp" android:color="#2E2E2E" />
</shape>
</item>
</selector>
Then, you can add the LinearLayout to your layout as follows.
your_layout.xml
<LinearLayout
android:layout_width="match_parent"
android:layout_height="56dp"
android:background="#drawable/rounded_border"
android:orientation="horizontal">
<EditText
android:layout_width="0dp"
android:layout_height="match_parent"
android:background="#null"
android:paddingHorizontal="16dp"
android:text="(504) 596-3245"
android:layout_weight="2"/>
<View
android:layout_width="2dp"
android:background="#2E2E2E"
android:layout_height="match_parent"/>
<Spinner
android:layout_width="0dp"
android:layout_height="match_parent"
tools:listitem="#layout/spinner_item_text"
android:layout_weight="1"/>
</LinearLayout>
Remarks
You can Customize the border width, color, and radius from the rounded_border.xml.

compile 'com.github.z2wenfa:SpinnerEditText:1.0.1'

How to add a fully transparent to semi-transparent gradient in Android

I have a situation where I want to add an image view doing the same effect as this app
As you notice there is a drawable or something hiding the bottom side of the view adding a transparent gradient. How can I achieve the same effect?

Well, you can use fadingEdge attribute of the listView in your xml. Make a listView, then add items xml (images in particular as you've mentioned above).
android:fadingEdge="horizontal"
android:fadingEdgeLength="30dp"
android:fillViewport="false"
android:requiresFadingEdge="vertical"

Place this drawable in the bottom of your layout:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="#FFFFFF"
android:endColor="#android:color/transparent"
android:angle="90" />
</shape>
Your layout:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/white" >
<View
android:layout_width="match_parent"
android:layout_height="20dp"
android:background="#drawable/gradient"
android:layout_gravity="bottom"/>
</FrameLayout>

I think you can change alpha value of that image View. Go through
this and this for more details.

Gradient Transparent Background

I want to get a transparent gradient over the image, why does transparency work:
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<com.twick.screens.custom.SquaredImageView
android:id="#+id/rv_image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/office"/>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#80abcdef" > //TRANSPARENT WORK
</FrameLayout>
</android.support.v7.widget.CardView>
and so there is no
android:background="#drawable/background_gradient_blue_indigo>//TRANSPARENT NOT WORK
background_gradient_blue_indigo :
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:angle="0"
android:endColor="#800055FA" //80 transaprent
android:startColor="#807942DF" //80 transparent/>
</shape>

Add android:alpha=0.8 (or whatever float value you want) along with android:background="#drawable/background_gradient_blue_indigo" to the FrameLayout.
However, please note that this will make the whole view transparent, not the drawable in the background.

Android : Rounded-edges view grow within another rounded-edges view

I am trying to make two rounded edges views, A and B, in Android. Both views have the same corner radius but B is within A or B should look like within A.
B's width is dynamic according to the percentage below. When the percentage is more than 5%, this works perfectly fine. However, as the percentage is less than 5%, it will turn out like the failure-figure below. They look like completely independence views, though they actually are. I need the green part grows within the gray area only. How can this be accomplished?
Ideally, it should look like
But I failed to make it. :/ The figure I got
Here is what I did, define a drawable as given below
<RelativeLayout
android:id="#+id/percentageBarViewGroup"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<View
android:id="#+id/a_Bar"
android:layout_width="match_parent"
android:layout_height="20dp"
android:background="#drawable/progress_bar_empty_background"/>
<View
android:id="#+id/b_Bar"
android:layout_width="0dp"
android:layout_height="20dp"
android:background="#drawable/progress_bar_progressing_background"/>
</RelativeLayout>

You should use nested views and padding .
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent">
<FrameLayout
android:id="#+id/a_Bar"
android:layout_width="match_parent"
android:layout_height="20dp"
android:background="#drawable/progress_bar_empty_background">
<View
android:id="#+id/b_Bar"
android:layout_width="0dp"
android:layout_height="match_parent"
android:background="#drawable/progress_bar_progressing_background"/>
</FrameLayout>
</RelativeLayout>
At the end add stroke to your progress_bar_progressing_backgroundwith the same color as progress_bar_empty_background.
something like this :
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="3dp"/>
<stroke android:width="2dp" android:color="#222"/>
<solid android:color="#fff"/>
</shape>

Android Zig-Zag layout

I'm in need of creating a receipt layout in Android. The idea is very simple, a rectangle layout with a zigzag top.
Even, i have tried dashed line but nothing working.
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="line">
<stroke
android:color="#FF00"
android:dashWidth="5dp"
android:dashGap="5dp" />
</shape>

Try with this: https://github.com/beigirad/ZigzagView
Support top and bottom Zigzag.
<ir.beigirad.zigzagview.ZigzagView
android:layout_width="match_parent"
android:layout_height="240dp"
app:zigzagBackgroundColor="#8bc34a"
app:zigzagElevation="8dp"
app:zigzagHeight="10dp"
app:zigzagShadowAlpha="0.9"
app:zigzagSides="top|bottom"
app:zigzagPaddingContent="16dp">
// add child view(s)
</ir.beigirad.zigzagview.ZigzagView>

Hi you can use this library android-shape-imageview. And use transparent shape like this
End use library.
<com.github.siyamed.shapeimageview.mask.PorterShapeImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:siShape="#drawable/zigzag"
android:src="#drawable/neo"
app:siSquare="true"/>
You can change app:siShape="#drawable/zigzag" to desired shape. You can create other png shape.

Create small triangle and use repeat background
repeat_background.xml
<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:src="#drawable/imagename"
android:tileMode="repeat" />
and use it in any view
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/repeat_background" />
refer this and this for more
