问题描述

我正在尝试在相对布局上方显示

I am trying to show a PopupWindow above relative layout.

 popupWindow.showAtLocation(layout,  Gravity.BOTTOM
            |Gravity.CENTER, 0, layout);

Where layout is a relative layout.But it appears only at the bottom.Not above the relativelayout. I have checked this.But it didn't helped.

Here is my PopupWindow layout

解决方案

you can use this method to do this

private void displayPopupWindow(View anchorView) {
        PopupWindow popup = new PopupWindow(Pdf.this);
        View layout = getLayoutInflater().inflate(R.layout.popup_content, null);
        popup.setContentView(layout);
        // Set content width and height
        popup.setHeight(WindowManager.LayoutParams.WRAP_CONTENT);
        popup.setWidth(WindowManager.LayoutParams.WRAP_CONTENT);
        // Closes the popup window when touch outside of it - when looses focus
        popup.setOutsideTouchable(true);
        popup.setFocusable(true);
        popup.setBackgroundDrawable(new BitmapDrawable());
        // Show anchored to button
        popup.showAtLocation(anchorView, Gravity.BOTTOM, 0,
                anchorView.getBottom() - 60);

        popup.showAsDropDown(anchorView);
    }
