style.xml android:windowIsTranslucent dialogs not showing - android

I have created a transparent AppCompatActivity that is a type of 'launcher' activity for other activities. This launcher activity uses a transparent style as found with other stackoverflow questions.
<style name="Theme.AppCompat.Translucent" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowIsFloating">true</item>
</style>
<style name="AppCompatAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="colorAccent">#color/primary</item>
</style>
Sometimes this launcher activity needs to show a progress dialog. However, the progress dialog does not show up when I use the tag android:windowIsTranslucent. Commenting out this tag allows the progress dialog to appear, but the activity is no longer transparent.
Is there some sort of alternative solution for this?


I didn't tried this solution, But i think this could work.
Just add <item name="android:windowIsTranslucent">false</item> in your AppCompatAlertDialogStyle
Solution would be like
<style name="Theme.AppCompat.Translucent" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowIsFloating">true</item>
</style>
<style name="AppCompatAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="colorAccent">#color/primary</item>
<item name="android:windowIsTranslucent">false</item>
</style>

How to make an activity background completely transparent (not translucent)?

In my android activity, I need to make the background of the activity transparent. For that, I found solutions online saying to do this in theme.
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">#android:color/transparent</item>
However this makes the activity background translucent i.e it isn't perfectly transparent, it is slightly grey. Is there a way to get a perfectly transparent background such that the screen below it is perfectly viisible. Thanks!

Try this
<item name="android:colorBackgroundCacheHint">#null</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">#color/transparent</item>

Try this
<style name="TransparentTheme.Base" parent="Theme.AppCompat.DayNight.NoActionBar">
<item name="colorPrimary">#color/primary</item>
<item name="colorPrimaryDark">#color/primaryDark</item>
<item name="colorAccent">#color/accent</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:backgroundDimEnabled">false</item>
</style>
Usage
<activity
android:name=".activity"
android:theme="#style/TransparentTheme.Base" />

How do you set DialogFragment.STYLE_NO_FRAME in styles.xml?

How do you set DialogFragment.STYLE_NO_FRAME, which hides the frame, in your styles.xml file? Or does this have to be done outside of the xml file?

Have a look at this link.
Put STYLE_NO_FRAME in styles.xml
<style name="DialogWindowAnim">
<item name="android:windowFrame">#null</item>
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowNoTitle">true</item>
<item name="android:backgroundDimEnabled">true</item>
<item name="android:windowEnterAnimation">#anim/slide_up_from_bottom</item>
<item name="android:windowExitAnimation">#anim/slide_down_to_bottom</item>
</style>
<style name="DialogSlideAnim" parent="DialogWindowAnim">
<item name="android:windowAnimationStyle">#style/DialogWindowAnim</item>
</style>
This is how I did it.

Styling of AlertDialog buttons

In my application I use holoeverywhere. I would like to change the appearance of AlertDialog and I got stuck on buttons below alert dialog. I took a look how things were done in holoeverywhere and I tried to modify that.
Here is backtracking of my reasoning:
In theme there are atributes which define alertDialogTheme and some other stuff. We will come back later to selectableItemBackground also.
<style name="Holo.Base.Theme" parent="Theme.AppCompat">
...
<item name="alertDialogTheme">#style/Holo.Theme.Dialog.Alert</item>
...
<item name="buttonBarButtonStyle">?borderlessButtonStyle</item>
...
<item name="selectableItemBackground">#drawable/item_background_holo_dark</item> *
...
</sytle>
So i figure alertDialogStyle is my target which is further defined in styles:
<style name="Holo.Base.Theme.Dialog" parent="Holo.Theme">
<item name="android:colorBackgroundCacheHint">#null</item>
<item name="android:windowAnimationStyle">#style/Holo.Animation.Dialog</item>
<item name="android:windowBackground">#drawable/dialog_full_holo_dark</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowFrame">#null</item>
<item name="android:windowIsFloating">true</item>
<item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
<item name="android:windowTitleStyle">#style/Holo.DialogWindowTitle</item>
<item name="borderlessButtonStyle">#style/Holo.Button.Borderless.Small</item>
<item name="buttonBarStyle">#style/Holo.ButtonBar.AlertDialog</item>
<item name="listPreferredItemPaddingLeft">16dip</item>
<item name="listPreferredItemPaddingRight">16dip</item>
<item name="windowActionBar">false</item>
<item name="windowActionModeOverlay">true</item>
<item name="windowAnimationStyle">#style/Holo.Animation.Dialog</item>
<item name="windowContentOverlay">#null</item>
<item name="windowMinWidthMajor">#dimen/dialog_min_width_major</item>
<item name="windowMinWidthMinor">#dimen/dialog_min_width_minor</item>
<item name="windowNoTitle">true</item>
</style>
<style name="Holo.Theme.Dialog" parent="Holo.Base.Theme.Dialog" >
</style>
<style name="Holo.Theme.Dialog.Alert" parent="Holo.Theme.Dialog">
<item name="alertDialogStyle">#style/Holo.AlertDialog</item>
<item name="alertDialogTitleDividerColor">#color/holo_blue_light</item>
<item name="android:windowBackground">#android:color/transparent</item>
</style>
<style name="Holo.Button.Borderless" parent="Holo.Button">
<item name="android:background">?selectableItemBackground</item>
<item name="android:paddingLeft">4dip</item>
<item name="android:paddingRight">4dip</item>
</style>
So Holo.Theme.Dialog.Alert is inherited from Holo:base.Theme.Dialog which has an atribute for borderlessButtonStyle, which I guess defines the buttons of alert dialog.
Style Holo.Button.Borderless referes the atribute selectableItemBackground for its background. Atribute is set in application theme itself. So, my reasoning is if I inherit from theme Holo.theme and set selectableBackground atribut my change should reflect in customized alert dialog buttons and everything else where this background is used.
<style name="ThemeCustom" parent="#style/Holo.Theme>
…
<item name="selectableItemBackground">#drawable/custom_item_background </item>
…
</style>
But this does not work. No change is visible in alert dialog buttons. Is there something wrong with my reasoning?

Applying Styles Android

I want to make my Activity appear like a Dialog box, but without the title bar. So I think I should write this style myself.
But how should this XML style be?
I already tried the Theme.Dialog for my Activity, but the thing is, I don't want the background of the Theme.Dialog style. And without an label for screen.
I has all the screen build by XML, I want just center it on screen and has a semi-transparent outside background.

Just do this
<activity android:name=".MyActivity"
android:theme="#style/CustomTheme"
android:label="Gana"/>
res/values/styles.xml
<resources>
<style name="CustomTheme" parent="android:Theme.Dialog">
<item name="android:windowNoTitle">true</item>
<item name="android:layout_width">wrap_content</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:background">#drawable/mybackground</item>
<item name="android:gravity">center</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowFrame">#null</item>
<item name="android:windowBackground">#android:color/transparent</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:backgroundDimEnabled">true</item>
<item name="android:background">#android:color/transparent</item>
</style>
If you don't want background remove that.
