活动中的暗淡或模糊背景

Question

In one of my project I used PopupWindow . My problem is while viewing popupwindow the design seems to be uncomfortable to work. So I want to dim or blur my activity background. I searched a lot, but most of the answers seems only for Dialog not for PopupWindow . Is it possible in android to dim our activity background while viewing PopupWindaow .

Answer 1

I solved this problem by setting the background to the layout of the pop-up window with the following.

android:background="#80FFFFFF"

Thnaks..And it works as expected.

Answer 2

you can simply use this :

ColorDrawable dw = new ColorDrawable(0xb0000000);
dialog.getWindow().setBackgroundDrawable(dw);

Answer 3

There is always a work around. Before showing your PopupWindow use another PopupWindow which has nothing but a dark translucent tint. Also when dismissing dismiss both pop up windows in the reverse sequence.

For code see this

Answer 4

是的，有可能，尝试android:theme="@android:style/Theme.Translucent" ，它会让你的活动透明化。

Answer 5

Try this

 Window window = popUpView.getWindow();
    WindowManager.LayoutParams wlp = window.getAttributes();
    wlp.gravity = Gravity.CENTER_VERTICAL;
    wlp.flags = WindowManager.LayoutParams.FLAG_DIM_BEHIND;
    wlp.dimAmount = (float) 1.0;
    window.setAttributes(wlp);
