推荐答案

Try this 它会去除边距并全屏显示对话框(无边距)

Try this It will remove side spaces and show your dialog as full screen(No side margins)

window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

上一行是最重要的，不要错过.

Above line is the most important, don't miss to include it.

final Dialog dialog = new Dialog(getActivity(), R.style.DialogAnimation);
dialog.getWindow().getAttributes().windowAnimations =
        R.style.DialogOpenAnimation;

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setCanceledOnTouchOutside(false);
dialog.setCancelable(true);
dialog.setContentView(R.layout.dialog_mediagallary);

ImageButton back_arrow = (ImageButton) dialog.findViewById(R.id.back);
viewPagerPhotoSlideShow = (ClickableViewPager) dialog.findViewById(R.id.photolist);
adapterPhotoViewPager = new AdaterViewPagerAllmeidagallary(getActivity(), pagerListItems);
viewPagerPhotoSlideShow.setAdapter(adapterPhotoViewPager);
viewPagerPhotoSlideShow.setCurrentItem(defaultPagerItemPosition);
back_arrow.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        dialog.dismiss();
    }
});

WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
lp.copyFrom(dialog.getWindow().getAttributes());
lp.width = WindowManager.LayoutParams.MATCH_PARENT;
lp.height = WindowManager.LayoutParams.MATCH_PARENT;
lp.gravity = Gravity.CENTER;

Window window = dialog.getWindow();
window.setAttributes(lp);
window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
dialog.show();
