How can I change default black dim background "color" (not the amount of dim) of Dialog?
This is a workaround but it's not really a pure solution because background touch is disabled and should be configured manually.
First, set custom dialog theme like this.
styles.xml
<style name="CustomDialogTheme" parent="android:Theme.Dialog">
<item name="android:windowNoTitle">true</item>
<item name="android:windowIsFloating">false</item>
<item name="android:windowBackground">@android:color/transparent</item>
</style>
Setting windowIsFloating
to false forces Dialog
view to be expanded to full screen. Setting windowBackground
to transparent
removes default black dim background under Dialog
. windowNoTitle
option gets rid of the upper title bar.
CustomDialog.java
Apply the theme and construct your custom_dialog
view as follows.
public HTCustomDialog(Context context) {
super(context, R.style.CustomDialogTheme);
setContentView(R.layout.custom_dialog);
}
custom_dialog.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/main_solid_80">
<RelativeLayout
android:id="@+id/dialog_root"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_marginLeft="50dp"
android:layout_marginRight="50dp"
android:background="@drawable/bg_popup"
android:padding="16dp">
</RelativeLayout>
Now that CustomDialog
view is a full-screen view, set background
of your root layout to whatever color you'd like.
Sample result
I mosaiced the result a bit.
use custom style.
<style name="transparent_dialog_borderless" parent="android:Theme.Dialog">
<item name="android:windowFrame">@null</item>
<item name="android:windowIsFloating">true</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowNoTitle">true</item>
<item name="android:background">#FF333333</item>
<item name="android:windowBackground">@null</item>
<item name="android:backgroundDimEnabled">true</item>
</style>
android:backgroundDimEnabled:control the black dim background
