android dialog transparent

I want to get rid of the border in my dialog box and make it look absolutly transparent, as if the image is on the top of screen.

enter image description here

My dialog xml is -

<?xml version="1.0" encoding="utf-8"?>


<ImageView android:id="@+id/ImageView01"
    android:layout_width="wrap_content" android:layout_height="wrap_content"
    android:layout_centerHorizontal="true" android:visibility="invisible"/>

The accepted answer causes issue with devices that have a notch, as the statusbar completely disappears and shows an ugly white background.

Instead, the right way for this is to define your own style.

<style name="FullScreenDialogTheme" parent="Theme.MaterialComponents.Dialog">
    <item name="android:windowIsFloating">false</item>
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:backgroundDimEnabled">false</item>
    <item name="android:statusBarColor">@color/colorPrimary</item>
</style>

Now, this will make the window not have borders and be transparent over the screen.

The simplest way of doing this is that in your DialogFragment's onCreate() method, call

setStyle(DialogFragment.STYLE_NO_FRAME, 0);

And if the view you returned in onCreateView does not have a background specified, the dialog's background will be just transparent.

Why? DialogFragment.STYLE_NO_FRAME means that OS will not do any drawing in the window of the dialog, and your view is 100% responsible for drawing everything about the dialog.

try this:-

final Dialog dialog = new Dialog(this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
dialog.setContentView(R.layout.splash);
dialog.show();

To give a translucent effect, say 50% opacity, use:

Drawable d = new ColorDrawable(Color.BLACK);
d.setAlpha(130);
mDialog.getWindow().setBackgroundDrawable(d);

'130' can be changed (0-255) to acheive desired opacity.
