How to blur/dim an activity when a popup window is shown in android
I use a popupwindow for displaying options in Android. I tried to dim/blur the activity when a popupwindow is active, but I did not find a solution... can anybody help me. I used the following code but it does not work for me. getWindow().addFlags(android.view.WindowManager.LayoutParams.FLAG_BLUR_BEHIND); Use it like this: WindowManager.LayoutParams lp = dialog.getWindow().getAttributes(); lp.dimAmount=0.0f; dialog.getWindow().setAttributes(lp); dialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND); 来源: https://stackoverflow.com/questions/8386410/how-to-blur-dim-an-activity
