Question

怎么实现弹出popuwindow之后父界面变暗

Answer 1

PopupWindow mPopupSkb;
PopUpView popupview = new PopUpView(mContext, null);
popupview.setBackgroundDrawable((getResources().getDrawable(R.drawable.textinput_predictive_popup_bg)));
mPopupSkb = new PopupWindow(popupview, LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
mPopupSkb.setOutsideTouchable(false);
mPopupSkb.setContentView(popupview);
ColorDrawable color = new ColorDrawable(-10000);
mPopupSkb.setBackgroundDrawable(color);
mPopupSkb.update();
mPopupSkb.showAtLocation(mSkbContainer, Gravity.CENTER, 50, 300);

我是这样做的， 但是我发现虽然设置成了LayoutParams.FILL_PARENT，
还是显示的半屏幕，只显示了半个粉色的屏幕
