Android Question [SOLVED?] Modifying radiobutton style

I'm guessing the title correctly summates the following.

For other reasons, I have added content to my apps manifest as per:

https://www.b4x.com/android/forum/t...efore-designer-script-work.65815/#post-416766

Problem is that now the only visible radio button in a nest is the checked one - all unchecked ones have no visible button - which to me looks a bit too minimalistic.

I'm assuming this is Material Design.

Is there any way to remedy this - I've been searching the forums and googling but am drowning in XML which is most definitely not my strong suit.

Thanks in advance for any help...

Erel, I actually said radiobutton, not checkbox.

No problem. They should look like:


I guess that you have set the background to be light instead of selecting a light theme and keeping the default colors.


Correct way to choose a light theme (manifest editor):
B4X: 
SetApplicationAttribute(android:theme, "@style/LightTheme")
CreateResource(values-v20, theme.xml,
<resources>
  <style
  name="LightTheme" parent="@android:style/Theme.Material.Light">
  </style>
</resources>
)
CreateResource(values-v14, theme.xml,
<resources>
  <style
  name="LightTheme" parent="@android:style/Theme.Holo.Light">
  </style>
</resources>
)

Erel,

As I said in the first post of this thread, this minor problem was introduced when I followed the suggestion in your post:

https://www.b4x.com/android/forum/t...efore-designer-script-work.65815/#post-416766

In that post you suggest:
B4X: 
SetApplicationAttribute(android:theme, "@style/NoActionBar")
CreateResource(values-v20, theme.xml,
<resources>
  <style
  name="NoActionBar" parent="@android:style/Theme.Material.NoActionBar">
  </style>
</resources>
)
CreateResource(values-v14, theme.xml,
<resources>
  <style
  name="NoActionBar" parent="@android:style/Theme.Holo.NoActionBar">
  </style>
</resources>
)

Which is obviously very similar to what you are now suggesting above.

I have tried putting both in my manifest but it appears whichever is last in the manifest wins - so I can either have one or the other - is there any way to combine them so that I get both no title bar and proper radiobutton bullets?

Thanks...

After a lot of suck'n'see and some more googling I have come up with a solution that seems to give me what I want by putting this in my app's manifest:
B4X: 
SetApplicationAttribute(android:theme, "@style/CPSTheme")
CreateResource(values-v20, theme.xml,
<resources>
  <color name="pitch_black">#FF000000</color>
  <style
  name="CPSTheme" parent="@android:style/Theme.Material.Light">
  <item name="android:colorPrimary">@color/pitch_black</item>
  <item name="android:windowBackground">@color/pitch_black</item>
  <item name="android:actionBarSize">0dp</item>
  <item name="android:windowNoTitle">true</item>
  </style>
</resources>
)
CreateResource(values-v14, theme.xml,
<resources>
  <color name="pitch_black">#FF000000</color>
  <style
  name="CPSTheme" parent="@android:style/Theme.Holo.Light">
  <item name="android:colorPrimary">@color/pitch_black</item>
  <item name="android:windowBackground">@color/pitch_black</item>
  <item name="android:actionBarSize">0dp</item>
  <item name="android:windowNoTitle">true</item>
  </style>
</resources>
)
<item name="android:colorPrimary">@color/pitch_black</item>
This gives me a black title background in the apps recents/overview entry.

<item name="android:windowBackground">@color/pitch_black</item>
This gives me a black screen when app is being launched - if left out it is white.

<item name="android:actionBarSize">0dp</item>
This cans the action bar.

<item name="android:windowNoTitle">true</item>
This cans the title.

I am testing on a Samsung S5 running Android 6.0.1 (Marshmallow) and think I am actually using the first block (i.e. parent="@android:style/Theme.Material.Light").

Is there any sneaky way I can test the second block?

Alternatively, could anyone test and/or tell me if the second block works - I read somewhere that colorPrimary was introduced with Lollipop - not exactly sure what this means for the relevance/stability of the second block running on pre-Lollipop devices.

Thanks again...
