Idea taken from Android: Blurring and dimming background windows from dialog. I'm having trouble getting the content under my dialog to blur. When calling eula.getWindow() I receive this error:
The method getWindow() is undefined for the type AlertDialog.Builder
The eula is displayed with this bit of code from the main activity:
EulaHelper.showEula(false, this);
Any help is greatly appreciated.
public static void showEula(final boolean accepted, final FragmentActivity 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);
}
getWindow()
is a method of the dialog class, not of the dialog builder. Your code should rather look like this:
AlertDialog dlg = eula.show();
WindowManager.LayoutParams lp = dlg.getWindow().getAttributes();
lp.dimAmount = 0.0F;
dlg.getWindow().setAttributes(lp);
dlg.getWindow().addFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND);
Note though that the FLAG_BLUR_BEHIND
constant is deprecated now, blurring behind windows is no longer supported. So your code might break in the future.
