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 r开发者_StackOverflow社区ight 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" />
