how to allow only one radiobtton to be executed in a radiogroup inside a linear layout?

I am trying to place a radio group with 3 radio buttons inside a linear layout. My aim is to choose only one RadioButton inside the RadioGroup but, it is giving me an error that there are multiple root tags. Can someone figure out how to solve this?
file.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="ok"
android:id="#+id/textemail"/>
<RadioGroup
android:layout_width="match_parent"
android:layout_height="match_parent">
<RadioButton
android:id="#+id/one"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="one" />
<RadioButton
android:id="#+id/two"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="two"
/>
<RadioButton
android:id="#+id/three"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="three" />
</RadioGroup>
<TextView
android:id="#+id/textView1"
android:layout_below="#+id/textemail"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="To:"
/>
<TextView
android:id="#+id/TextTo"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="khushi"/>
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Comment:"
/>
<TextView
android:id="#+id/TextS3"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="your comment"
/>
<TextView
android:id="#+id/textView4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="email us "
android:textAppearance="?android:attr/textAppearanceLarge" />
<EditText
android:id="#+id/editText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="top"
android:inputType="textMultiLine"
android:lines="10" />
<Button
android:id="#+id/button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Send"
android:textStyle="italic"/>
</LinearLayout>

You immediately close your radiogroup:
<RadioGroup
android:layout_width="match_parent"
android:layout_height="match_parent"/>
This should be:
<RadioGroup
android:layout_width="match_parent"
android:layout_height="match_parent"> // Note that there is no forward slash at the end
And you are not closing the RadioGroup:
</RadioButton> <-- This should be </RadioGroup>

Your RadioButton (views) should be children of the RadioGroup(view). By closing your RadioGroup using /> you declare the RadioButton(s) and the RadioGroup as children of the LinearLayout.
The Following should work.
<?xml version="1.0" encoding="utf-8"?>
<Linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="hello"
android:id="#+id/textview"/>
<RadioGroup
android:layout_width="match_parent"
android:layout_height="match_parent">
<RadioButton
android:id="#+id/one"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="one" />
<RadioButton
android:id="#+id/two"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="two"
/>
<RadioButton
android:id="#+id/three"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="three" />
</RadioButton>
</RadioGroup>
<TextView
android:id="#+id/textViewllol"
android:layout_below="#+id/textemail"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="hi:"
/>
<TextView
android:id="#+id/Texme"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text=""
/>
<TextView
android:id="#+id/textView3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="comment:"
/>
<TextView
android:id="#+id/Text2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="your comments"
/>
<TextView
android:id="#+id/textView45"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="ok"

<Button
android:id="#+id/button4785"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="send"
/>
</LinearLayout>

Change below -
<RadioGroup
android:layout_width="match_parent"
android:layout_height="match_parent"/>
to
<RadioGroup
android:layout_width="match_parent"
android:layout_height="match_parent">
<RadioButton
android:id="#+id/one"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="one" />
<RadioButton
android:id="#+id/two"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="two"
/>
<RadioButton
android:id="#+id/three"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="three" />
</RadioGroup>
One of your Text is not in correct format change it as below -
<TextView
android:id="#+id/textView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="ok:"
/>
to
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="ok:"
/>
One more error -
change below -
<RadioGroup
android:layout_width="match_parent"
android:layout_height="match_parent">
to
<RadioGroup
android:layout_width="match_parent"
android:layout_height="wrap_content">

You have one </Radiobutton> tag above </Radiogroup> that shouldn't be here. Just remove it to have :
<RadioGroup
android:layout_width="match_parent"
android:layout_height="match_parent">
<RadioButton
android:id="#+id/one"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="one" />
<RadioButton
android:id="#+id/two"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="two"
/>
<RadioButton
android:id="#+id/three"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="three" />
</RadioGroup>

Android radio button text truncated

I have an app that shows a Radio Group with four Radio Buttons whose test is set dynamically. I am no able to get the whole text on a single line.
It gets wrapped on two lines, or truncated at the end. It seems like there is a vertical edge, and text cannot go over it.
My layout is
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="vds.quizmanager.QuizManagerActivity" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginBottom="41dp"
android:text="Domanda:" />
<TextView
android:id="#+id/textView2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginTop="19dp" />
<RadioGroup
android:id="#+id/radioGroup1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/textView2"
android:layout_marginTop="24dp"
android:layout_toLeftOf="#+id/button2" >
<RadioButton
android:id="#+id/radio0"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:minWidth="#dimen/activity_vertical_margin" />
<RadioButton
android:id="#+id/radio1"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<RadioButton
android:id="#+id/radio2"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<RadioButton
android:id="#+id/radio3"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</RadioGroup>
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/radioGroup1"
android:layout_centerHorizontal="true"
android:layout_marginTop="90dp"
android:text="Domanda" />
</RelativeLayout>

OK then you can try this code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/RelativeLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginBottom="41dp"
android:text="Domanda:" />
<TextView
android:id="#+id/textView2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginTop="19dp"
android:text="sdfsgdshfdgsasRFAGRESTDGHFSAFAWhtjygukjtyhergwrqTQETWRYJETRHEWRQEJTUKRYJTRHEAWRWetjyurrutjretwrtjyeukyriu" />
<RadioGroup
android:id="#+id/radioGroup1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/textView2"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_marginTop="24dp"
android:layout_toLeftOf="#+id/button2" >
<RadioButton
android:id="#+id/radio0"
android:text="Domandaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa:"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:minWidth="#dimen/activity_vertical_margin" />
<RadioButton
android:id="#+id/radio1"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<RadioButton
android:id="#+id/radio2"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<RadioButton
android:id="#+id/radio3"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</RadioGroup>
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/radioGroup1"
android:layout_centerHorizontal="true"
android:layout_marginTop="90dp"
android:text="Domanda" />
</RelativeLayout>
This is result:

RadioButton in multirow in single RadioGroup

I need to create design like radiobutton in multi-row in single radiogroup like this image .
I am using android:orientation="horizontal"
layout.xml
<RadioGroup
android:id="#+id/radiogroup"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="horizontal" >
<RadioButton
android:id="#+id/option1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checked="true"
android:singleLine="false"
android:text="option1" />
<RadioButton
android:id="#+id/option2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checked="true"
android:singleLine="false"
android:text="option2" />
<RadioButton
android:id="#+id/option3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checked="true"
android:singleLine="false"
android:text="option3" />
<RadioButton
android:id="#+id/option4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checked="true"

android:singleLine="false"
android:text="option5" />
<RadioButton
android:id="#+id/option6"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checked="true"
android:singleLine="false"
android:text="option6" />
</RadioGroup>
Thanks..

parent can be any like linear horizontal or relative(i'd prefer Linear Horizontal), inside that 3 TableRow childs,within each tableRow your RadioButtons. something like this
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<TableRow android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
<RadioGroup>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Radio1"
/>
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Radio2"/>
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Radio3"/>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"

android:layout_height="wrap_content"
android:text="Radio4"
/>
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Radio5"/>
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Radio6"/>
</LinearLayout>
</RadioGroup>
</TableRow>
<TableRow android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
<RadioGroup>
<LinearLayout
android:layout_width="fill_parent"

android:text="Radio2"/>
<RadioButton

What you are trying to achieve is possible.
You will have to subclass TableLayout and add the radio buttons programmatically

Beginner android developer - having difficulty with layouts

I have a button that's below a ScrollView, the button is set to align to the parents bottom. The scroll view is set to wrap_content for its height. Once the ScrollView is filled with content it appears beneath the button. How can I set it to not go behind the button, for the ScrollViewto end when the button begins?
I've tried placing android:layout_below in the bottom button, and when that didn't work I tried layout_above in the ScrollView for above the button. That last one caused my app to crash on start, no idea why. The first one once the ScrollView is longer than the screen it causes the button to be placed underneath with no way to access it.
Here's my XML file.
<RelativeLayout 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="#color/light_blue"
android:padding="5dp"
tools:context=".MainActivity" >
<EditText
android:id="#+id/editText_query"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="#string/queryPromt"
android:imeOptions="actionNext"
android:inputType="text"
android:textColor="#000" />
<EditText
android:id="#+id/editText_tag"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/editText_query"
android:layout_marginTop="10dp"
android:layout_toLeftOf="#+id/saveButton"
android:hint="#string/tagPrompt"
android:imeOptions="actionDone"
android:inputType="text" />
<Button
android:id="#id/saveButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_below="#id/editText_query"
android:text="#string/save" />
<TextView
android:id="#+id/textView_taggedSearches"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignRight="#id/saveButton"
android:layout_below="#id/saveButton"
android:layout_marginTop="10dp"
android:background="#666"
android:gravity="center_horizontal"
android:text="#string/taggedSearches"
android:textColor="#FFF"
android:textSize="18sp" />
<ScrollView
android:id="#+id/scrollView_query"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/textView_taggedSearches"
android:padding="5dp" >
<TableLayout
android:id="#+id/tableLayout_query"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="5dp"
android:stretchColumns="*" >
</TableLayout>
</ScrollView>
<Button
android:id="#+id/button_clearTags"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:text="#string/clearTags" />
</RelativeLayout>

Try adding
android:layout_below="#id/scrollView_query"
to the last button

You can use layout_weight for this. If you set layout_height to "0px" you can use layout_weight to distribute the remaining parent space between sibling items.
In this case you want the button to have its normal size, and the scrollview to occupy whatever space remains. This should give you the general idea:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ScrollView
android:layout_width="fill_parent"
android:layout_height="0px"
android:layout_weight="1" >
<TableLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</ScrollView>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>

I did this before in my project. and here is my xml code. you can modify it as per your usage.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
