semi-circle button android

I have two buttons and I want to change the shape of them to be semi-circles. Then place them beside each other to make a full circle. An image has been attached to show how I want the buttons to look. Any help would be greatly appreciated. Thank you.

You have to create one drawable xml file.
left_corner.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="1dp"
android:bottomRightRadius="0dp" android:bottomLeftRadius="25dp"
android:topLeftRadius="25dp" android:topRightRadius="0dp"/> // here you have to put dimen as per reqiurement
<solid android:color="#color/green" />
</shape>
right_corner.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="1dp"
android:bottomRightRadius="25dp" android:bottomLeftRadius="0dp"
android:topLeftRadius="0dp" android:topRightRadius="25dp"/> // here you have to put dimen as per reqiurement
<solid android:color="#color/green" />
</shape>
layout.xml
<Linearlayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button android:layout_width="#dimen/_150sdp"
android:layout_height="#dimen/_150sdp"
android:background="#draable/left_corner"/>
<Button android:layout_width="#dimen/_150sdp"
android:layout_height="#dimen/_150sdp"
android:background="#draable/right_corner"/>
</Linearlayout>
This was work for me..

Hope this will help~

Hi user23423534,
Applying xml shape as background to button and placing button side by side will help u solve the problem.

Please check the below code.
Layout file:
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:layout_width="50dp"
android:layout_height="100dp"
android:background="#drawable/shape"/>
<Button
android:layout_width="50dp"
android:layout_height="100dp"
android:background="#drawable/shape1"/>
</LinearLayout>

set space between rows in listview Android

I have a listView with custom rows and I need to set a custom divider between each row.
This is the code of the listView:
<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingTop="#dimen/menu_padding"
android:background="#color/customBlue"
android:divider="#drawable/list_divider"
android:dividerHeight="2px" />
This is the code of the rows:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="50dp"
android:orientation="horizontal"
tools:ignore="contentDescription"
android:background="#color/strongBlue" >
<ImageView
android:id="#+id/row_icon"
android:layout_width="50dp"
android:layout_height="50dp"
android:padding="10dp"
android:src="#drawable/ic_launcher" />
<TextView
android:id="#+id/row_title"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center_vertical"
android:padding="10dp"
android:textColor="#color/white"
android:textAppearance="#android:style/TextAppearance.Medium" />
</LinearLayout>
And this is the code for the 2 pixel divider:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:bottom="1px">
<shape android:shape="line">
<stroke
android:color="#0C0832"
android:width="2dp"
/>
<size
android:height="1px"
/>
</shape>
</item>
<item android:top="1px">
<shape android:shape="line">
<stroke
android:color="#2D2E57"
android:width="2dp"
/>
<size
android:height="1px"
/>
</shape>
</item>
</layer-list>
The problem is that I have a random space between each row that has the same color as the listView backgroundColor and if I set the dividerHeight to 4px I can see my divider. How can I remove the space that gets created automatically and only have my custom divider?

Use the following code in rows in linear layout
android:layout_marginTop="15dp"

Instead of pixel you can provide dp in xml
android:dividerHeight="10dp"
android:divider="#ffffff"
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="schemas.android.com/apk/res/android">;
<gradient
android:type="radial"
android:startColor="#343030"
android:endColor="#151515"
android:gradientRadius="300"
android:angle="270"
android:centerY="0.3"/>
</shape>
Instead of making custom drawable for divider you can directly give color to divider.

Background EditText and ImageView are black?

I'm creating a custom border to LinearLayout, to do it I'm using shape . The problem is when I set #drawable/custom_linear_border all EditText has background black. This problem occur with Android 2.3 because superior this problem does not occur.
How could I solve it ?
custom_linear_border
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke
android:width="2dip"
android:color="#android:color/darker_gray" />
</shape>
LinearLayout
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/custom_linearlayout_border"
android:layout_marginTop="50dp"
>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="15dp"
android:src="#drawable/icon_login"
/>
<EditText
android:id="#+id/etEmail"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="13dp"
android:layout_gravity="center_vertical"
android:hint="Email"
android:inputType="textEmailAddress"
android:background="#00000000"
/>
</LinearLayout>

//Use this drawable
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#android:color/transparent" />
<stroke
android:width="2dip"
android:color="#android:color/darker_gray" />
</shape>

Design XML Button Android

Here is an example of an app that used XML to design button.
How can i have the same design with XML?
How make my buttons look like it is floating just like in the image below?

I think you will need to use a shape drawable with a layered list, here is an example of a button that has a different color on the top and bottom (the drop shadow effect). You will set this as the background attribute of the Button.
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle" >
<corners android:radius="2dp" />
<solid android:color="#color/button_border_dark" />
</shape>
</item>
<item android:top="1dp">
<shape android:shape="rectangle" >
<corners android:radius="2dp" />
<solid android:color="#color/button_border_light" />
</shape>
</item>
<item
android:bottom="1dp"
android:top="1dp">
<shape android:shape="rectangle" >
<corners android:radius="2dp" />
<solid android:color="#color/button_general_color" />
</shape>
</item>
</layer-list>

Here is the XML of the Button. You can also use custom typeface as well as shadows to make it the way you want.
<Button
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:background="#android:color/holo_blue_dark"
android:textColor="#android:color/white"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:layout_gravity="center"
android:shadowColor="#android:color/holo_blue_light"
android:id="#+id/btnClickMe"
android:text="Click Me!"
/>

Use this one....
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical" >
<Button
android:id="#+id/button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginLeft="25dp"
android:layout_marginRight="25dp"
android:background="#drawable/selected" // selected is the name of your custom file
android:text="Register"
android:textColor="#fff" />
<Button
android:id="#+id/button2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginLeft="25dp"
android:layout_marginRight="25dp"
android:background="#37a8f7"
android:text="Login"
android:layout_marginTop="15dp"
android:textColor="#fff" />
</LinearLayout>
you can make custom file selected.xml in drawable folder for red button.
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#ff0000"/>
<corners android:radius="1dp"/>
<padding android:left="3dp" android:top="2dp"
android:right="3dp" android:bottom="2dp" />
</shape>
and set it to your red button.
And you can make same as for your blue button.

Android UI display differently in graphical layout and AVD

I try to make a rouned EditText.It display well in the Graphical layout in main.xml. But it is still square when i launch the AVD.Here is the code:
<EditText
android:id="#+id/et"
android:layout_width="300dp"
android:layout_height="wrap_content"
android:padding="5dp"
android:hint="Enter a #hashtag or keyword"
android:textColor="#000000"
android:drawableLeft="#drawable/magnifier"
android:background="#drawable/rounded_edittext"
android:textSize="16dp" >
<requestFocus />
</EditText>
<!-- res/drawable/rounded_edittext.xml --> <shape xmlns:android="http://schemas.android.com/apk/res/android"
android:padding="10dp"
android:shape="rectangle" >
<solid android:color="#FFFFFF" />
<corners
android:bottomLeftRadius="15dp"
android:bottomRightRadius="15dp"
android:topLeftRadius="15dp"
android:topRightRadius="15dp" />

This a rounded edit text that change also behavour on clik states, Simply use thes xml
<?xml version="1.0" encoding="utf-8"?>
<!-- res/drawable/rounded_edittext_states.xml -->
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_pressed="true"
android:state_enabled="true"
android:drawable="#drawable/rounded_focused" />
<item
android:state_focused="true"
android:state_enabled="true"
android:drawable="#drawable/rounded_focused" />
<item
android:state_enabled="true"
android:drawable="#drawable/rounded_edittext" />
</selector>
Normal rounded edittext:
<?xml version="1.0" encoding="utf-8"?>
<!-- res/drawable/rounded_edittext.xml -->
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" android:padding="10dp">
<solid android:color="#FFFFFF"/>
<corners
android:bottomRightRadius="15dp"
android:bottomLeftRadius="15dp"
android:topLeftRadius="15dp"
android:topRightRadius="15dp"/>
</shape>
Pressed,Focused edittext
<?xml version="1.0" encoding="utf-8"?>
<!-- res/drawable/rounded_edittext_focused.xml -->
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" android:padding="10dp">
<solid android:color="#FFFFFF"/>
<stroke android:width="2dp" android:color="#FF0000" />
<corners
android:bottomRightRadius="15dp"
android:bottomLeftRadius="15dp"
android:topLeftRadius="15dp"
android:topRightRadius="15dp"/>
</shape>
And... now, the EditText should look like:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/hello"
android:background="#drawable/rounded_edittext_states"
android:padding="5dip"/>
</LinearLayout>
i used this layout to test it for and it works for me even with multiple round edittext:
this is the layout i use
<?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"
android:orientation="vertical" >
<EditText
android:id="#+id/et"
android:layout_width="300dp"
android:layout_height="wrap_content"
android:background="#drawable/rounded_edittext"
android:drawableLeft="#drawable/ic_launcher"
android:hint="Enter a Login"
android:textColor="#000000"
android:textSize="16dp"
android:padding="5dp">
<requestFocus />
</EditText>
<EditText
android:id="#+id/et2"
android:layout_width="300dp"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/et"
android:layout_marginTop="14dp"
android:background="#drawable/rounded_edittext"
android:drawableLeft="#drawable/ic_launcher"
android:ems="10"
android:hint="Enter a Password"
android:padding="5dp"
android:textColor="#000000"
android:textSize="16dp" />
</RelativeLayout>
and this is a screen capture of the result on emulator:

// I feel that your rounded_edittext.xml is wrong.
can you remove this 2 lines
android:padding="10dp"
android:shape="rectangle"
//Or you can use myshape.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#FAFFFA"/>
<corners android:bottomRightRadius="15dp" android:bottomLeftRadius="15dp"
android:topLeftRadius="15dp" android:topRightRadius="15dp"/>
<stroke android:width="3dp" android:color="#C3C3C3"/>
</shape>
