define what follows in the styles.xml file在styles.xml文件中定义以下内容
<style name="CustomDialog" parent="android:Theme.Dialog">
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">@android:color/transparent</item>
</style>
and pass it as argument to the AlertDialog constructor并将其作为参数传递给AlertDialog构造函数
AlertDialog.Builder imageDialog = new AlertDialog.Builder(SubProducts.this, R.style.CustomDialog);
Or programmatically, through the Dialog instance you can call或者以编程方式，您可以通过Dialog实例调用
myDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT))

One more solution:另一种解决方案：
When using Alertdialog.builder - Its not giving getwindow() option in it.使用Alertdialog.builder - 它没有提供getwindow()选项。 So we can make it work like this:所以我们可以让它像这样工作：
AlertDialog dialog = builderScan.create();
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
dialog.show();
And your Background of AlertDialog will be transperent.您的AlertDialog背景将是透明的。

Instead of this:取而代之的是：
imageDialog.create();
imageDialog.show();
you could try doing something like this:你可以尝试做这样的事情：
AlertDialog imageDialogAlert = imageDialog.create();
imageDialogAlert.show();
imageDialogAlert.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

If you just want to remove white background from the dialog layout then you just add:如果您只想从对话框布局中删除白色背景，那么您只需添加：
dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
If you also want remove window background translucent colour for the dialog then you need to add both lines:如果您还想删除对话框的窗口背景半透明颜色，则需要添加两行：
dialog.getWindow().setDimAmount(0f);
dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);

The code below changes the background layout.下面的代码更改了背景布局。
LayoutInflater inflater = MainActivity.this.getLayoutInflater();
View layout = inflater.inflate(R.layout.your_layout, null);
final AlertDialog alertDio = new AlertDialog.Builder(MainActivity.this)
.setView(layout)

alertDio.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.parseColor("#801b5e20")));

First set a custom theme for alert dialog in theme.xml首先在 theme.xml 中为警报对话框设置自定义主题
<style name="YourThemeName" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="colorAccent">#CC8800</item>
<item name="android:windowBackground">@android:color/transparent</item>
</style>
after this set this theme on your AlertDialog在此之后在您的 AlertDialog 上设置此主题
AlertDialog.Builder alertDialog = new AlertDialog.Builder(requireActivity(),R.style.YourThemeName;
alertDialog.setView(R.layout.your_custom_view);
alertDialog.setCancelable(false);
alertDialog.create();
alertDialog.show();
