How to disable radiobutton's text from clickable feature?

I need to select radio button while touching only the icon of a radio button. By default when i touch on the radio button's text, the radio button also get checked. How can i disable the feature?
<RadioGroup
android:id="#+id/optionGroup"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<RadioButton
android:id="#+id/radio1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checked="true"
android:text="RadioButton"
android:textColor="#color/optionText"
android:textSize="#dimen/text_exam"
android:gravity="top" />
<RadioButton
android:id="#+id/radio2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="RadioButton"
android:textColor="#color/optionText"
android:textSize="#dimen/text_exam"
android:gravity="top" />
<RadioButton
android:id="#+id/radio3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="RadioButton"
android:textColor="#color/optionText"
android:textSize="#dimen/text_exam"
android:gravity="top" />
<RadioButton
android:id="#+id/radio4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="RadioButton"
android:textColor="#color/optionText"
android:textSize="#dimen/text_exam"
android:gravity="top" />
</RadioGroup>

To answer your question, you can't do it using the default radiobutton class.
The android-radiobutton is an object of the class which actually makes the radiobutton itself. This class sets the properties of the RadioButton, and, to a certain extent, you cannot change these properties. You can, however, make it unclickable, change the color, set the text, however, you cannot change what portion of the button is clickable. To do that, you must make your own class of a RadioButton, and extend it to the class that you are using.
Only way is by making your own class. Let me know if this answered your question.

Try this simple hack
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="RadioButton"/>
</LinearLayout>

Radio Group android

I started to develop for Android few days ago and I got stuck trying to use Radio Group. In my code for some reason all of the radio buttons can be selected together.
Any suggestion?
xml:
<RadioGroup
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/rG">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="89dp"
android:layout_below="#id/title"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true">
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="95"
android:layout_marginLeft="75sp"
android:layout_marginTop="20sp"
android:id="#+id/rb95"
android:layout_gravity="left|top"
android:checked="true"/>
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="98"
android:id="#+id/rb98"
android:layout_gravity="right|top"
android:layout_alignTop="#+id/rb95"
android:layout_alignLeft="#+id/rbs"
android:layout_alignStart="#+id/rbs"/>
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="96"
android:id="#+id/rb96"
android:layout_gravity="left"
android:layout_below="#id/rb95"
android:layout_alignLeft="#id/rb95"
android:layout_alignStart="#id/rb95"/>
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="soler"
android:id="#+id/rbs"
android:layout_gravity="right"
android:layout_marginRight="75dp"
android:layout_alignTop="#id/rb96"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"/>
</RelativeLayout>
</RadioGroup>

Pull the RadioButtons out of the RelativeLayout (get completely rid of it: it's not only misplaced, but also useless) and they will work as expected.
If you really need the RelativeLayout as a container for the RadioGroup, then swap the RelativeLayout and RadioGroup (RelativeLayout on the outside)

I think your problem is that you have a relativeLayout inside your RadioGroup.
Here is the Google Developer page on radio buttons.

Have horizontal RadioButtons wrap if too long for screen

So I have the following radiobuttons. I want to have them display like this:
However this occurs:
How I can get it to display like above? I can move in the GUI editor in Eclipse it but it removes the RadioButton from the RadioGroup!Within the group, it ignores all other layout parameters.
<RadioGroup
android:id="#+id/radioGroup1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/timeBar"
android:layout_marginTop="43dp"
android:orientation="horizontal" >
<RadioButton
android:id="#+id/privRadio0"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Everyone" />
<RadioButton
android:id="#+id/privRadio1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checked="true"
android:text="FriendOfFriends" />
<RadioButton
android:id="#+id/privRadio2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Friends" />
</RadioGroup>

You can simply copy this class:
https://github.com/jevonbeck/AbstractMachine/blob/jevon_dev/app/src/main/java/org/ricts/abstractmachine/ui/utils/MultiLineRadioGroup.java
into an appropriate package in your project and instantiate in XML like so:
<view
class="mypackage.packagepath.MultiLineRadioGroup"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"/>

What you are asking for is a FlowLayout. Such a layout has the benefit of only wrapping when it's needed, as opposed to 0gravity's more "static" solution.

Manage Layout Inside a Horizontal Oriented Radiogroup

I am using a TableLayout with TableRows as my main activity.
Inside the TableLayout is a Radio Group containing 2 Radio Buttons inside the activity (the Radio Group being inside a table row). I want to be able to align the rightmost radio button to the right edge screen, so the "gap" is between the left radio button and right button (instead of after the right radio button). i.e.
So instead of having
| (x) (x) gap |
I will have
|(x) gap (x)|
where (x) are the Radio Buttons and | are the edges of the screen
I can use gravity (center_horizontal) to put both the buttons in the middle (i.e. | gap (x)(x) gap|) however I can't seem to be able to split them the way I want as said before

All you need to evenly space an arbitrary number of buttons horizontally across the screen:
RadioGroup has to have
android:orientation="horizontal" &
android:layout_width="fill_parent"
Each radio button has to have
android:layout_weight="1", except
the rightmost button (to make it
line up on the right edge of the
screen)!
This took me hours to figure out.
Here is some example code, with a bonus of two text labels and the right and left edges of the screen, for a survey app.
<RadioGroup
android:id="#+id/radio_group"
android:orientation="horizontal"
android:layout_below="#id/question"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:visibility="gone"
>
<RadioButton
android:id="#+id/strong_disagree_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="1"
/>
<RadioButton
android:id="#+id/disagree_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="#string/disagree"
/>
<RadioButton
android:id="#+id/neutral_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="#string/neutral"
/>
<RadioButton
android:id="#+id/agree_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="#string/agree"
/>
<RadioButton
android:id="#+id/strong_agree_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="5"
/>
</RadioGroup>
<TextView
android:id="#+id/disagree_label"
android:text="#string/strongly_disagree_txt"
android:layout_below="#id/radio_group"
style="#style/TextAppearance"
android:visibility="gone"
/>
<TextView
android:id="#+id/agree_label"
android:text="#string/strongly_agree_txt"
android:layout_below="#id/radio_group"
android:layout_alignParentRight="true"
style="#style/TextAppearance"
android:layout_width="wrap_content"
android:visibility="gone"
/>

Found my solution. A combination of weights and gravity and removing the margins. The radio group can have layout_width="fill_parent". Each radio button should have layout_weight="1", but the layout_width for each radiobutton must still be specified to override the default of "37" which I guess is the default radio button image width.
<RadioGroup android:id="#+id/overall"
android:layout_width="fill_parent" android:layout_height="80dp"
android:gravity="center"
android:orientation="horizontal">
First button should have:
android:layout_weight="1"
android:layout_gravity="center|left"
Last button should have:
android:layout_gravity="center|right"
Note: all buttons have layout_gravioty set, but no layout_weight setting for the right most button!

Did you ever find a solution to this? My intermediate solution might help, but it's not the full picture for me. I've been able to do this by setting specific widths, but this does not allow the view to resize to fit the screen width:
<RelativeLayout
android:id="#+id/overall_layout"
android:layout_width="290dp" android:layout_height="wrap_content">
<RadioGroup android:id="#+id/overall"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:orientation="horizontal">
<RadioButton android:id="#+id/overall_1" android:tag="1"
android:button="#drawable/radio_1"
android:layout_width="50dp"
android:layout_marginRight="10dp"
android:layout_height="wrap_content"></RadioButton>
<RadioButton android:id="#+id/overall_2" android:tag="2"
android:button="#drawable/radio_2"
android:layout_width="50dp"
android:layout_marginRight="10dp"
android:layout_height="wrap_content"></RadioButton>
<RadioButton android:id="#+id/overall_3" android:tag="3"
android:button="#drawable/radio_3"
android:layout_width="50dp"
android:layout_marginRight="10dp"
android:layout_height="wrap_content"></RadioButton>
<RadioButton android:id="#+id/overall_4" android:tag="4"
android:button="#drawable/radio_4"
android:layout_width="50dp"
android:layout_marginRight="10dp"
android:layout_height="wrap_content"></RadioButton>
<RadioButton android:id="#+id/overall_5" android:tag="5"
android:button="#drawable/radio_5"
android:layout_width="50dp"
android:layout_height="wrap_content"></RadioButton>
</RadioGroup>
<TextView android:text="left" android:id="#+id/left"
android:layout_below="#id/overall"
android:layout_alignParentLeft="true"
android:layout_width="wrap_content" android:layout_height="wrap_content"></TextView>
<TextView android:text="right" android:id="#+id/right"
android:layout_below="#id/overall"
android:layout_alignParentRight="true"
android:layout_width="wrap_content" android:layout_height="wrap_content"></TextView>
</RelativeLayout>
Note there is no margin on the last button.
I am trying to have 5 custom buttons in a radio group, with the 1st left-justified and the last right-justified. The buttons are exactly 50 pixels wide and I don't want any text associated with the buttons individually. The 2 texts below are left and right-justfied in the relative layout. Using "layout_gravity" has no effect and "layout_weight" adds padding to the right of each button, which causes the right-most button to no longer be justified.
Much hair-pulling on this.

If i understand you question right, you can also try next code inside RadioGroup:
<ToggleButton
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<View
android:id="#+id/view1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1" />
<ToggleButton
android:layout_width="wrap_content"
android:layout_height="wrap_content" />

Problem with sizes of EditText and Button in Android

I want to make the edittext width the same size as button. My EditText is currently very small. I use relative layout.
<TextView
android:id="#+id/aha4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="17dip"
android:text="Vzdevek:"
android:layout_below="#id/aha3" />
<EditText android:id="#+id/nick"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_below="#id/nivo"
android:layout_toRightOf="#id/aha4"/>
<Button android:id="#+id/poslji"
android:text="Pošlji"
android:layout_height="wrap_content"
android:layout_width="20dip"
android:typeface="serif" android:textStyle="bold"
android:layout_alignParentRight="true"
android:layout_below="#id/nivo"
android:layout_toRightOf="#id/nick"/>
What i currently get is this:
alt text http://www.shrani.si/f/1Z/x8/2lWB3f8p/device.png
What is the appropriate layout_width for edittext and button?

As you are using something like a row to show the TextView, EditText and button, you can try to use TableLayout: http://developer.android.com/guide/tutorials/views/hello-tablelayout.html
Also, make sure you set android:layout_width="wrap_content" so that the EditText use as much space as possible.

Try to assign equal weight to both button and edit text
Yeah, you're right about weight.
As a hack you can do this. Not exactly right though.
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="#+id/aha4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="17dip"
android:text="Vzdevek:" />
<Button
android:id="#+id/poslji"
android:text="Pošlji"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:paddingLeft="40dip"
android:paddingRight="40dip"
android:typeface="serif"
android:textStyle="bold"
android:layout_alignParentRight="true" />
<EditText
android:id="#+id/nick"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_toRightOf="#id/aha4"
android:layout_toLeftOf="#id/poslji" />
</RelativeLayout>

I managed to solve it with specifying minWidth and maxWidth for EditText.
