注意:不要使用builder来改变背景。
Dialog dialog = new Dialog.Builder(MainActivity.this)
.setView(view)
.create();
dialog.show();dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
改变
Dialog dialog = new Dialog(getActivity());
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(view);
dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
dialog.show();
使用对话框时。builder,它没有给出getWindow()选项。
其他回答
添加以下代码
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
或者换成这个:
dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
在你的代码中试试这个:
getWindow().setBackgroundDrawableResource(android.R.color.transparent);
它肯定会起作用……对我来说…!我的弗洛伊德
在我的案例中,解决方案是这样的:
final Drawable drawable = new ColorDrawable(android.graphics.Color.TRANSPARENT);
dialogAssignTag.getWindow().setBackgroundDrawable(drawable);
另外,在自定义对话框的xml文件中:
android:alpha="0.8"
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
*/
Window window = d.getWindow();
window.setFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND,WindowManager.LayoutParams.FLAG_BLUR_BEHIND);
这是我的方法,你可以试试!
