popup_more_account.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="200.0dip"

        android:listSelector="@drawable/list_selector" >
    </ListView>

</LinearLayout>

item_account_list.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:descendantFocusability="blocksDescendants"
    android:padding="5dip" >

    <TextView
        android:id="@+id/txt_user_account"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:singleLine="true"
        android:text="20101681"
        android:textColor="@color/black"
        android:textSize="20.0dip" />

    <ImageButton
        android:id="@+id/txt_user_delete"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="60dip"
        android:background="@drawable/btn_delete_user"
        android:focusable="false"
        android:textSize="15.0dip" />

</LinearLayout>

View moreAccountView = LayoutInflater.from(LoginActivity.this)
						.inflate(R.layout.popup_more_account, null);

				ListView lvAccounts = (ListView) moreAccountView
						.findViewById(R.id.lv_popup_accounts);
				ListViewAccountAdapter adapter = new ListViewAccountAdapter(
						LoginActivity.this);
				lvAccounts.setAdapter(adapter);

				lvAccounts.measure(0, 0);
				int height = lvAccounts.getMeasuredHeight();

				PopupWindow mPopupWindow = new PopupWindow(moreAccountView,
						edtAccount.getWidth(), height);
				Drawable backgroup = LoginActivity.this.getResources()
						.getDrawable(R.drawable.transparent);
				mPopupWindow.setBackgroundDrawable(backgroup);

				int pos[] = new int[2];
				edtAccount.getLocationOnScreen(pos);

				mPopupWindow.showAtLocation(edtAccount, Gravity.LEFT
						| Gravity.TOP, pos[0], pos[1] + edtAccount.getHeight());

我想要的效果就是moreAccountView里多少内容，moreAccountView就有多高，请问怎么实现？
