Set the root layout background to transparent in XML:
`android:background=”@android:color/transparent”`
Example:
` ` android:layout_width=”match_parent”` ` android:layout_height=”match_parent”` ` android:background=”@android:color/transparent”>` For a `ConstraintLayout`, use the same background attribute: `android:background=”@android:color/transparent”` If setting background programmatically: `view.setBackgroundColor(Color.TRANSPARENT)` If using a custom drawable, make sure its alpha is transparent For the window background, set in theme: `android:windowBackground=”@android:color/transparent”` For an Activity dialog-style transparent window: `getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT))` If needed, disable default dimming: `getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND)`
