How can I make the background of my dialog in android transparent?-CodePudding

I am trying to make the background from my dialog transparent. I want the progress bar to be shown in front of my activity. Unfortunately, the background stays always white.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@ id/loading_cont"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:backgroundTint="#00000000"
android:background="@android:color/transparent"
>

<RelativeLayout
    android:id="@ id/loading_dialog_container"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:backgroundTint="#00000000"
    android:background="@android:color/transparent"
    >

    <ProgressBar
        android:id="@ id/login_progress"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerInParent="true" >
    </ProgressBar>

</RelativeLayout>

Make a new Drawable Resource file named transparent.xml.

transparent.xml

<shape 
      android:shape="rectangle"
      xmlns:android="http://schemas.android.com/apk/res/android">
</shape>

Now set android:background="@drawable/transparent"

CodePudding user response：

Add this code where you are initializing your dialog

dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);

or you can also add this code instead

 dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
