copied!<p>After (too much) research, I stumbled on <a href="https://stackoverflow.com/a/4536955/358813">the excellent answer of Neil Traft</a>.</p> <p>Adapting his work for the <code>GridView</code> has been dead easy.</p> <p>ExpandableHeightGridView.java:</p> <pre><code>package com.example; public class ExpandableHeightGridView extends GridView { boolean expanded = false; public ExpandableHeightGridView(Context context) { super(context); } public ExpandableHeightGridView(Context context, AttributeSet attrs) { super(context, attrs); } public ExpandableHeightGridView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } public boolean isExpanded() { return expanded; } @Override public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { // HACK! TAKE THAT ANDROID! if (isExpanded()) { // Calculate entire height by providing a very large height hint. // View.MEASURED_SIZE_MASK represents the largest height possible. int expandSpec = MeasureSpec.makeMeasureSpec(MEASURED_SIZE_MASK, MeasureSpec.AT_MOST); super.onMeasure(widthMeasureSpec, expandSpec); ViewGroup.LayoutParams params = getLayoutParams(); params.height = getMeasuredHeight(); } else { super.onMeasure(widthMeasureSpec, heightMeasureSpec); } } public void setExpanded(boolean expanded) { this.expanded = expanded; } } </code></pre> <p>Include it in your layout like this:</p> <pre><code><com.example.ExpandableHeightGridView android:id="@+id/myId" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center" android:horizontalSpacing="2dp" android:isScrollContainer="false" android:numColumns="4" android:stretchMode="columnWidth" android:verticalSpacing="20dp" /> </code></pre> <p>Lastly you just need to ask it to expand:</p> <pre><code>mAppsGrid = (ExpandableHeightGridView) findViewById(R.id.myId); mAppsGrid.setExpanded(true); </code></pre>
