@BILL
You should create the alertdialog from the builder.
AlertDialog a = eula.create();
a.show();
and then call a.getwindows().getattribues() on the alert dialog.
Without showing the alert dialog get window will fail.

I cannot get this to work. Any help is greatly appreciated. It states that “The method getWindow() is undefined for the type AlertDialog.Builder”. Here’s the code I’m using:

public static void showEula(final boolean accepted, final Activity activity) {
AlertDialog.Builder eula = new AlertDialog.Builder(activity)
.setTitle(R.string.eula_title)
.setIcon(android.R.drawable.ic_dialog_info)
.setMessage(activity.getString(R.raw.eula))
.setCancelable(accepted);

if (accepted) {
// If they’ve accepted the EULA allow, show an OK to dismiss.
eula.setPositiveButton(android.R.string.ok,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
} else {
// If they haven’t accepted the EULA allow, show accept/decline buttons and exit on
// decline.
eula
.setPositiveButton(R.string.accept,
new android.content.DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
setAcceptedEula(activity);
dialog.dismiss();
}
})
.setNegativeButton(R.string.decline,
new android.content.DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
activity.finish();
}
});
}
eula.show();
WindowManager.LayoutParams lp = eula.getWindow().getAttributes();
lp.dimAmount = 0.0F;
eula.getWindow().setAttributes(lp);
eula.getWindow().addFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND);

}

Thank you very very much for such precise and fully-working piece of code.

I also searched for that for minutes and your site just answered me in 4 lines and 5 secondes

Thx

setContentView(R.layout.main);
mDialog = new ProgressDialog(this); mDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
mDialog.setCancelable(true);

mDialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND);

WindowManager.LayoutParams lp = mDialog.getWindow().getAttributes();
lp.dimAmount = 0.0f;
mDialog.getWindow().setAttributes(lp);

Doesn’t really work… I even tried to modify the styles.xml file. Please help.

This helped out immensely.

I tried to override the AlertDialog theme originally and was not having very much success.

Thanks! People don’t waste 3 hours like I did. You have to SHOW the dialog first or in my case with a custom dialog setContentView() first BEFORE, like so. Or it WONT work.

SkillMenuView skillMenuView = new SkillMenuView(this);
setContentView(skillMenuView);

WindowManager.LayoutParams lp = getWindow().getAttributes();
lp.dimAmount = 0.0F;
lp.screenBrightness = 1.0F;
getWindow().setAttributes(lp);

I haven't tested it but I think this is how you would do it:

WindowManager.LayoutParams lp = dialog.getWindow().getAttributes();
lp.alpha=0.5f;
dialog.getWindow().setAttributes(lp);

By setting alpha to 0.5 it should make the window 50% transparent. Try it out let me know how it goes...

Is it possible that removing blur, dimming of the background using your technique ?
