Custom theme dialog : transparent background

tikimove · by **tikimove** » Wed Jul 29, 2009 5:05 pm

Hi all,

I'm trying to make a custom theme dialog, which extends android:Theme.Dialog :

Syntax: [ Download ] [ Hide ]

Using xml Syntax Highlighting

 
        <style name="RunesDialog" parent="@android:style/Theme.Dialog">
 
                <item name="android:windowBackground">@drawable/cadre_dialogue
 
                </item>
 
                <item name="android:buttonStyle">@style/button</item>
 
                <item name="android:textViewStyle">@style/textview</item>
 
                <item name="android:editTextStyle">@style/edittext</item>
 
        </style>
 
Parsed in 0.002 seconds,  using GeSHi 1.0.8.4

So I can use it in the manifest :

Syntax: [ Download ] [ Hide ]

Using xml Syntax Highlighting

 
        <activity android:name=".act.MyActivity" android:theme="@style/RunesDialog" />
 
Parsed in 0.000 seconds,  using GeSHi 1.0.8.4

If I directly use the android:Theme.Dialog theme, the background is transparent, but if I use RunesDialog, the background is always black. Can you help me with that ?

Thanks a lot

Just for information, here is the Theme.Dialog description from Android source code :

    <style name="Theme.Dialog">
 
        <item name="android:windowFrame">@null</item>
 
        <item name="android:windowTitleStyle">@android:style/DialogWindowTitle</item>
 
        <item name="android:windowBackground">@android:drawable/panel_background</item>
 
        <item name="android:windowIsFloating">true</item>
 
        <item name="android:windowContentOverlay">@null</item>
 
        <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
 
        <item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
 
    </style>

What's your @drawable/cadre_dialogue ?

Hi,

Here is the cadre_dialogue image. It's a nine patch.

Hi, I'm just curious how does it look without the

<item name="android:windowFrame">@null</item>

line?

tikimove · by **tikimove** » Thu Aug 13, 2009 12:44 pm

Thanks for the tip, I will test ASAP and let you know.

Hi All!

I have the same problem with background transparency.

I made my Theme.CustomDialog

Syntax: [ Download ] [ Hide ]

Using xml Syntax Highlighting

    <style name="Theme.RCAlertDialog" parent="android:style/Theme.Dialog">
 
        <item name="android:windowBackground">@drawable/filled_box</item> 
 
    </style>
Parsed in 0.001 seconds,  using GeSHi 1.0.8.4

but when I use it in AndroidManifest file background is BLACK.

Syntax: [ Download ] [ Hide ]

Using xml Syntax Highlighting

 <activity android:name=".alert.CustomAlert"
 
                android:label="test title"
 
                android:theme="@style/Theme.RCAlertDialog">
 
            <intent-filter>
 
                <action android:name="android.intent.action.MAIN" />
 
                <category android:name="android.intent.category.SAMPLE_CODE" />
 
            </intent-filter>
 
        </activity>
Parsed in 0.001 seconds,  using GeSHi 1.0.8.4

If I use @android:style/Theme.Dialog then Background transperent, but apearence of my window as in standart dialog

Do you have any ideas how to use custom style for dialog? Can you check this tutorial?

Actually I don't know why, but even if it doesn't work on the emulator, sometimes it works on the real device. I can't understand :/

Today, I solve the problem. I just reboot my PC. And Run again Emulator and all works fine. I think it's a little bag of Emulator.

hi guys,

i had the same pb... neither emulator reboot nor real device reboot solve my pb...

but i solve it by copying the "<item name="android:windowIsFloating">true</item>"

in my custom theme

Edit : oups... it works only on the virtual device, but not on the real one (G1 with cupcake)

I had the same problem with creating a transparent dialog background - this works on 1.5 emulator / G1, and on 1.6 / 2.0 emulator - anyone running 1.6/2.0 on a real device to test there too? This was agonizing:

<style name="Theme.TransparentDlgTest">
<item name="android:windowBackground">@android:color/transparent</item>
<item name="android:windowFrame">@null</item>
<item name="android:windowContentOverlay">@null</item>
<item name="android:windowIsFloating">true</item>
<item name="android:backgroundDimEnabled">true</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
</style>

Thanks

it still works fine on emulator, but still not working on real device...

I try "setTheme()", and creating layout in java code, style with parent (android:style/Theme.Dialog), without parent (but all items)

but nothing do the job...

Hi,

Can you please try this again to verify it didn't work for you? This worked for me, even on my G1. Add this to your res/values/styles.xml file:

Syntax: [ Download ] [ Hide ]

Using xml Syntax Highlighting

 
    <style name="Theme" parent="android:Theme.Light">
 
    </style>
 
    <style name="Theme.TransparentTest">
 
      <item name="android:windowBackground">@android:color/transparent</item>
 
      <item name="android:windowFrame">@null</item>
 
      <item name="android:windowContentOverlay">@null</item>
 
      <item name="android:windowIsFloating">true</item>
 
      <item name="android:backgroundDimEnabled">true</item>
 
      <item name="android:windowIsTranslucent">true</item>
 
      <item name="android:windowNoTitle">true</item>
 
      <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
 
     </style>
 
Parsed in 0.003 seconds,  using GeSHi 1.0.8.4

then in your manifest file, pick some activity and apply the style:

Syntax: [ Download ] [ Hide ]

Using xml Syntax Highlighting

 
  <activity android:name="MyActivity"
 
     android:theme="@style/Theme.TransparentTest">
 
  ...
 
Parsed in 0.000 seconds,  using GeSHi 1.0.8.4

when you start that activity, the background should be transparent. Let me know if it works.

Thanks
