android listpopupwindow list item textview not being multiline

问题

I am using ListPopupWindow with custom list item layout. But list item TextView isn't being multi-line. How can I do that?

final ListPopupWindow showRoomListPopupWindow = new ListPopupWindow(
                getActivity());
        showRoomListPopupWindow.setAdapter(new ArrayAdapter(
                getActivity(),
                R.layout.movie_detail_spinner_item, movieShowRoomARList));
        showRoomListPopupWindow.setModal(true);
//        showRoomListPopupWindow.setWidth(ListPopupWindow.MATCH_PARENT);


        showRoomListPopupWindow.setAnchorView(tvProgramSeansClick_TXT);

XML layout:

<?xml version="1.0" encoding="utf-8"?>
<TextView
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:padding="10dp"
        android:textStyle="bold"
        android:minLines="3"
        android:singleLine="false"
        />

I tried to recreate your case, and I've managed to get your code working, just doing the following:

My AnchorView is a Button, inside a RelativeLayout, like this:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
  <Button
    android:id="@+id/popup"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:background="@null"
    android:visibility="invisible"
    android:text="Popup"
    android:textAppearance="@android:attr/textAppearanceSmall" />

Then, I have the following code inside my Activity onCreate():

Button popupButton = (Button) findViewById(R.id.popup);

    ArrayList<String> array = new ArrayList<String>();
    array.add("spendisse vel libero lacinia neque hendrerit posuere nec ac sem. Aliquam laoreet ullamcorper tortor, tincidunt suscipit eros pulvinar dictum. Cras eleifend ante at laoreet facilisis. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridic lorem ipsum");
    array.add("Odio. Quisque at rutrum tellus. Nullam hendrerit nisl non ligula condimentum varius aliquet eget turpis. Cras cursus arcu ornare elit dictum, et aliquet sem condimentum. Praesent mauris mi, malesuada volutpat dictum a, porta non mauris. Cras non sce");
    array.add("Neque porro quisquam est qui dolorem ipsum quia dolor sit amet, consectetur, adipisci veli");
    array.add("ltricies interdum sit amet nec ante. Suspendisse vel dolor dolor. Donec eget mattis lorem. Donec eget quam porta, hendrerit sapien a, interdum arcu. Integer rutrum, ante sed posuere adipiscing, nisl mi malesuada lorem, quis egestas sem augue fauci");

    final ListPopupWindow showRoomListPopupWindow = new ListPopupWindow(SecondActivity.this);
    showRoomListPopupWindow.setAdapter(new ArrayAdapter(SecondActivity.this,
            R.layout.movie_detail_spinner_item, array));
    showRoomListPopupWindow.setModal(true);

    showRoomListPopupWindow.setAnchorView(popupButton);

    showRoomListPopupWindow.setWidth(ListPopupWindow.WRAP_CONTENT);

    showRoomListPopupWindow.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            Toast.makeText(SecondActivity.this, "Clicked item " + position, Toast.LENGTH_SHORT).show();
        }
    });

    popupButton.post(new Runnable() {
        public void run() {
            showRoomListPopupWindow.show();
        }
    });

Note that all my strings are very long, and my Button has its visibility set to INVISIBLE, not GONE.

And this is what I get:
