PopupWindow的使用以及注意事项

PopupWindow

popupWindow = new PopupWindow(view, LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT, true);

//实例化一个ColorDrawable颜色为半透明

ColorDrawable dw = new ColorDrawable(0x00000000);

//设置SelectPicPopupWindow弹出窗体的背景

popupWindow.setBackgroundDrawable(dw);

popupWindow.setOutsideTouchable(false);

popupWindow.setFocusable(true);

popupWindow.setAnimationStyle(R.style.PopupAnimation);

//在PopupWindow里面就加上下面代码，让键盘弹出时，不会挡住pop窗口。

popupWindow.setInputMethodMode(PopupWindow.INPUT_METHOD_NEEDED);

popupWindow.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

popupWindow.update();

popupWindow.showAtLocation(rl, Gravity.BOTTOM|Gravity.CENTER_HORIZONTAL, 0, 0);

popupWindow去除黑边，只要给他设置背景就可以

popupWindow可以根据屏幕的宽度和它显示在的控件的宽度来确定其显示的位置
