问题
Is it possible to add a little bit of space between a RadioButton and the label while still using Android's built-in components? By default the text looks a little scrunched.
<RadioButton android:id="@+id/rb1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="My Text"/>
I've tried a couple of things:
Specifying margin and padding seem to add space around the entire element (button and text, together). That makes sense, but doesn't do what I need.
Creating a custom drawable via XML specifying images for the checked and unchecked states, then adding a few extra pixels to the right side of each image. This should work, but now you are stepping outside the default UI. (Not the end of the world, but not ideal)
Add extra whitespace to the beginning of each label. Android seems to trim a leading space character, as in " My String", but specifying unicode U+00A0, as in "\u00A0My String" does the trick. This works, but it seems kinda dirty.
Any better solutions?
回答1:
For anyone reading this now, the accepted answer will lead to some layout problems on newer APIs causing too much padding.
On API <= 16 you can set paddingLeft on the radio button to set the padding relative to the radio button's view bounds. Additionally, a patch nine background also changes the view bounds relative to the view.
On API >= 17 the paddingLeft (or paddingStart) is in relation to the radio button drawable. Same applies to the about a patch nine. To better illustrate padding differences see the attached screenshot.
If you dig through the code you will find a new method in API 17 called getHorizontalOffsetForDrawables. This method is called when calculating the left padding for a radio button(hence the additional space illustrated in the picture).
TL;DR Just use paddingLeft if your minSdkVersion is >= 17. If you support API <= 16, you should have radio button style for the min SDK you are supporting and another style for API 17+.

Not sure if this will fix your problem, but have you tried Radio Button's "Padding left" property with a value of 50dip or more
回答3:
i tried several ways and finished with this one working correctly on both emulator and devices:
<RadioButton
android:background="@android:color/transparent"
android:button="@null"
android:drawableLeft="@drawable/your_own_selector"
android:drawablePadding="@dimen/your_spacing" />
- android:background needs to be transparent as it seems on api10 there is a background with intrinsic paddings (not tried with other apis but the solution works on others too)
- android:button needs to be null as paddings will not work correctly otherwise
- android:drawableLeft needs to be specified instead of android:button
- android:drawablePadding is the space that will be between your drawable and your text
回答4:
Add margin between a radiobutton its label by paddingLeft:
android:paddingLeft="10dip"
Just set your custom padding.
RadioButton's xml property.
<RadioButton
android:id="@+id/radHighest"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:button="@drawable/YourImageResource"
android:drawablePadding="50dp"
android:paddingLeft="10dip"
android:text="@string/txt_my_text"
android:textSize="12sp" />
Done
回答5:
Use the following XML attributes. It worked for me
For API <= 16 use
android:paddingLeft="16dp"
For API >= 17 use
android:paddingStart="@16dp"
Eg:
<android.support.v7.widget.AppCompatRadioButton
android:id="@+id/popularityRadioButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:checked="true"
android:paddingEnd="@dimen/radio_button_text"
android:paddingLeft="@dimen/radio_button_text"
android:paddingRight="@dimen/radio_button_text"
android:paddingStart="@dimen/radio_button_text"
android:text="Popularity"
android:textSize="@dimen/sort_dialog_text_size"
android:theme="@style/AppTheme.RadioButton" />
Further More: drawablePadding attribute doesn't work. It only works if you added a drawable in your radio button. For Eg:
<RadioButton
android:id="@+id/radioButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:button="@null"
android:drawableEnd="@android:drawable/btn_radio"
android:drawablePadding="56dp"
android:drawableRight="@android:drawable/btn_radio"
android:text="New RadioButton" />
回答6:
Can't try this right now to verify, but have you tried to see if the attribute android:drawablePadding does what you need?
回答7:
final float scale = this.getResources().getDisplayMetrics().density;
checkBox.setPadding(checkBox.getPaddingLeft() + (int)(10.0f * scale + 0.5f),
checkBox.getPaddingTop(),
checkBox.getPaddingRight(),
checkBox.getPaddingBottom());
回答8:
I have tried, "android:paddingLeft" will works. paddingLeft will only impact the text while keep the radio image stay at the original position.
回答9:
The padding between the drawables and the text. It will be achieved by adding line below in xml file.
android:drawablePadding="@dimen/10dp"
回答10:
The "android:paddingLeft" only seems to work correctly under android 4.2.2
i have tried almost all versions of android and it only works on the 4.2.2 version.
回答11:
I came here looking for an answer and the simplest way (after some thinking) was add spacing at the beginning of the label itself like so
<RadioGroup
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignRight="@+id/btnChangeMode"
android:layout_marginTop="10dp"
android:layout_marginBottom="10dp"
android:layout_below="@+id/view3"
android:gravity="center|left"
android:id="@+id/ledRadioGroup">
<RadioButton
android:button="@drawable/custom_radio_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=" On"
android:layout_marginRight="6dp"
android:id="@+id/ledon"
android:textColor="@color/white" />
<RadioButton
android:button="@drawable/custom_radio_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=" Off"
android:layout_marginLeft="6dp"
android:id="@+id/ledoff"
android:textColor="@color/white" />
回答12:
for me works:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true">
<layer-list>
<item android:right="5dp">
<shape android:paddingLeft="5dp" android:shape="oval">
<size android:width="20dp" android:height="20dp" />
<solid android:color="@color/blue" />
</shape>
</item>
</layer-list>
</item>
<item android:paddingLeft="5dp" android:state_checked="false">
<layer-list>
<item android:right="5dp">
<shape android:paddingLeft="5dp" android:shape="oval">
<size android:width="20dp" android:height="20dp" />
<solid android:color="@color/grey" />
</shape>
</item>
</layer-list>
</item>
</selector>
回答13:
<RadioButton
android:id="@+id/rb1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:background="@null"
android:paddingLeft="20dp"
android:text="1"
android:textColor="@color/text2"
android:textSize="16sp"
android:textStyle="bold" />
回答14:
You can this code on your XML file
<RadioButton
android:id="@+id/rButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawablePadding="50dp"
android:paddingLeft="10dip"
android:text="@string/your_text" />
or use this on Activity class
radioButton.setPadding(12, 10, 0, 10);
回答15:
Use gravity
android:gravity="center_horizontal|center_vertical"
回答16:
Create a style in style.xml like this
<style name="Button.Radio">
<item name="android:paddingLeft">@dimen/spacing_large</item>
<item name="android:textSize">16sp</item>
</style>
Put that style in radio button
<RadioButton
android:id="@+id/rb_guest_busy"
android:layout_width="match_parent"
android:layout_height="48dp"
android:text="@string/guest_is_waiting"
android:textSize="@dimen/font_size_3x_medium"
android:drawablePadding="@dimen/spacing_large"
android:textColor="@color/color_text_heading_dark"
style="@style/Button.Radio"/>
You can change any attribute same as button as it RadioButton indirectly inherits button.
回答17:
You could try using the gravity attribute of radio button .
<RadioButton
android:id="@+id/rb_all"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:checked="true"
android:gravity="right|center_vertical"
android:padding="@dimen/padding_30dp"
android:text="@string/filter_inv_all"
android:textColor="@color/black"
android:textSize="@dimen/text_size_18" />
This will align the text to the right most end . Check out the first radio in the image.
回答18:
I'm using different approach that I think should work on all API versions. Instead of applying padding I'm adding an empty view between to RadioButtons:
<View
android:layout_width="20dp"
android:layout_height="1dp" />
This should give you 20dp padding.
回答19:
I know it is an old question, but with this solution, I finally got peace of mind and forget about API level.
Left side vertical RadioGroup with right side vertical text view.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<RadioGroup
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_vertical">
<RadioButton
android:id="@+id/radio1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<RadioButton
android:id="@+id/radio2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</RadioGroup>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginLeft="8dp"
android:gravity="center_vertical"
android:text="Radio 1"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginLeft="8dp"
android:gravity="center_vertical"
android:text="Radio 2"/>
</LinearLayout>
</LinearLayout>
