Android PopupWindow and WRAP_CONTENT don't work together

Question

I open a popu window like this:

mInfoPopup = new PopupWindow(layout, 400, 600, true);
mInfoPopup.setWindowLayoutMode(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);

The window then gets the exact size specified (400x600) and does NOT adjust its size to its content. What do I need to change so that the popup window will actually wrap around its contents?

Solution 1

Simply changed the way you create it by:

PopupWindow popupMenu = new PopupWindow(layout, ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT, true);

Solution 2

PopupWindow popupWin = new PopupWindow(mContext);
// WRAP_CONTENT works well for height, but not for width.
popupWin .setHeight(ViewGroup.LayoutParams.WRAP_CONTENT); 
// Measure layout here, then we can get measureHeight.
layout.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);
popupWin .setWidth(layout.getMeasuredWidth()); 
popupWin .setContentView(layout);
popupWin .showAsDropDown(anchorView,0 ,0, Gravity.NO_GRAVITY);

I found a solution that works for me (I am working with API 10), you can use it:

popupWindow.setWindowLayoutMode(
    ViewGroup.LayoutParams.WRAP_CONTENT,
    ViewGroup.LayoutParams.WRAP_CONTENT);
popupWindow.setHeight(1);
popupWindow.setWidth(1);

If you don't set height/width or set 0 it won't work. Example:

...
private Button button;

protected void onCreate(Bundle savedInstanceState) {
    ...
    attached_button.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {                
            LayoutInflater layoutInflater = (LayoutInflater) getBaseContext()
                    .getSystemService(LAYOUT_INFLATER_SERVICE);
            View popupView = layoutInflater.inflate(R.layout.popup_layout, null);

            final PopupWindow popupWindow = new PopupWindow(getApplicationContext());
            popupWindow.setContentView(popupView);
            popupWindow.setWindowLayoutMode(
                    ViewGroup.LayoutParams.WRAP_CONTENT,
                    ViewGroup.LayoutParams.WRAP_CONTENT);
            popupWindow.setHeight(1);
            popupWindow.setWidth(1);
            popupWindow.setFocusable(true);

            Button dismiss = (Button) popupView
                    .findViewById(R.id.dismiss);

            dismiss.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                    popupWindow.dismiss();
                }
            });

            popupWindow.showAsDropDown(button);

        }
    });

I hope to help you.

Following code worked for me.

LayoutInflater layoutInflater = LayoutInflater.from(context);
View layout = layoutInflater.inflate(R.layout.popup_layout, null);
PopupWindow popup = new PopupWindow(context);
popup.setContentView(layout);
popup.setWidth(ListPopupWindow.WRAP_CONTENT);
popup.setHeight(ListPopupWindow.WRAP_CONTENT);

Here, used popup.setWidth(ListPopupWindow.WRAP_CONTENT) instead of popup.setWidth(ViewGroup.LayoutParams.WRAP_CONTENT) in my case.

Solution 5

don't use RelativeLayout in layout, replace LinearLayout, maybe it's working.

popview = LayoutInflater.from(context).inflate(R.layout.pop_citypicker, null);

popwindow = new PopupWindow(popview, ViewGroup.LayoutParams.MATCH_PARENT,
        ViewGroup.LayoutParams.WRAP_CONTENT);

This worked for me as well. It shouldn't work, since ListPopupWindow has nothing to do with PopupWindow. I think we are just getting lucky -- the value of the constant is -2, which gives the correct behavior, whereas ViewGroup.LayoutParams.WRAP_CONTENT's value is -1.

This doesn't work in the case where the content is larger than the allowable space under or above the anchor view. Or if the content isn't measured until later.

This is the only solution which works in my case. Thx

But required API >= 19

Easy solution for me. Changed my relative layout to linear and it's fixed
