I have a ListView inside a android.support.v7.widget.GridLayout, here is my code:
<?xml version="1.0" encoding="utf-8"?><android.support.v7.widget.GridLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" app:columnCount="4" app:orientation="horizontal"><!-- Sort --><Space android:layout_width="@dimen/dialog_content_space" app:layout_gravity="fill_vertical" app:layout_rowSpan="2" /><TextView style="@style/TextView" android:layout_width="@dimen/none" android:layout_height="@dimen/dialog_content_row_height" android:text="@string/sort" app:layout_columnWeight="1" /><Spinner android:id="@+id/spinner_sort" style="@style/Spinner" android:layout_width="@dimen/none" android:layout_height="@dimen/dialog_content_row_height" app:layout_columnWeight="1" /><Space android:layout_width="@dimen/dialog_content_space" app:layout_gravity="fill_vertical" app:layout_rowSpan="2" /><TextView android:id="@+id/txt_filter" style="@style/TextView" android:layout_width="@dimen/none" android:layout_height="@dimen/dialog_content_row_height" android:text="@string/filter" app:layout_columnWeight="1" /><Spinner android:id="@+id/spinner_filter" style="@style/Spinner" android:layout_width="@dimen/none" android:layout_height="@dimen/dialog_content_row_height" app:layout_columnWeight="1" /><include layout="@layout/divider" android:layout_width="match_parent" android:layout_height="@dimen/divider_height" android:layout_marginTop="@dimen/divider_margin" app:layout_columnSpan="4" /><ListView android:id="@+id/layout_courses" android:layout_width="@dimen/none" android:layout_height="@dimen/none" app:layout_rowWeight="1" app:layout_gravity="fill" app:layout_columnSpan="4" android:divider="@null" android:scrollbars="none"/><Space android:layout_width="@dimen/none" android:layout_height="12dp" app:layout_gravity="fill" app:layout_columnSpan="4"/></android.support.v7.widget.GridLayout>`What it's shown in the Design tab in AndroidStudio it's exactly what I wanted to achieve, but when I run my app in an Android device the ListView it's completely empty.
I'm guessing it has something to do with the fact that the ListView width and height are both 0dp (that's the value for @dimen/none), but with these values it's the only way I can get my desired result.
