使用这段代码,它是为我工作:
Dialog dialog = new Dialog(getActivity(),android.R.style.Theme_Translucent_NoTitleBar);
dialog.show();

与zGnep相同的解决方案,但使用xml:
android:background="@null"
你可以使用:
setBackgroundDrawable(null);
方法。下面是文档:
/**
* Set the background to a given Drawable, or remove the background. If the
* background has padding, this View's padding is set to the background's
* padding. However, when a background is removed, this View's padding isn't
* touched. If setting the padding is desired, please use
* {@link #setPadding(int, int, int, int)}.
*
* @param d The Drawable to use as the background, or null to remove the
* background
*/
在Kotlin中,你可以使用以下代码:
val dialog = Dialog(context)
dialog.window?.decorView?.background = null
使用这段代码,它是为我工作:
Dialog dialog = new Dialog(getActivity(),android.R.style.Theme_Translucent_NoTitleBar);
dialog.show();
对话框弹出填充默认的黑色背景颜色或主题颜色,所以你需要设置透明的背景到对话框。试试下面的代码:-
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();
