小编Aji*_*kya的帖子

我在DialogFragment中显示snackbar在alertDialog的正面点击中.这是我的代码片段.

Snackbar snackbar = Snackbar.make(view, "Please enter customer name", Snackbar.LENGTH_LONG)
                .setAction("Action", null);
View sbView = snackbar.getView();
sbView.setBackgroundColor(Color.BLACK);
snackbar.show();

我正在将对话片段的视图传递给快餐栏.我想要背景颜色为黑色？我怎样才能做到这一点？我在DialogFragment中返回alertDialog.我正在设置对话框的主题如下

<style name="MyAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">

    <!-- Used for the buttons -->
    <item name="colorAccent">@color/accent</item>
    <!-- Used for the title and text -->
    <item name="android:textColorPrimary">@color/primary</item>
    <!-- Used for the background -->
    <item name="android:background">@color/white</item>
</style>

虽然我将背景颜色设置为白色以进行对话,但是应该通过将背景颜色设置为快餐栏来覆盖它.

下面是我的代码snipet.
