  1. POAndroid: how to force GridView width to wrap_content?
    text
    copied!<p>My GridView contains columns of fixed width, with fixed horizontal spacing. If there are not enough columns to fill the screen horziontally, I would like my GridView's width to wrap to its contents, and to center vertical in the screen.</p> <p>However, regardless of the number of columns I use, the GridView's width grows to fill the screen. The attached image shows this, where the green GridView fills the screen horizontally, despite having only 3 columns and its width being set to "wrap_content". </p> <pre><code>public class Temp extends Activity { private GridView grid; private int columnWidth = 80; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); View view = getLayoutInflater().inflate(R.layout.gridview, null); grid = (GridView) view.findViewById(R.id.grid); grid.setColumnWidth(columnWidth); grid.setAdapter(new GridAdapter()); setContentView(view); } class GridAdapter extends BaseAdapter { public GridAdapter() { } public int getCount() { return 3; } public Object getItem(int position) { return null; } public long getItemId(int position) { return position; } public View getView (int position, View convertView, ViewGroup parent) { View ret; if (convertView == null) { ret = new ImageView(Temp.this); ret.setLayoutParams(new GridView.LayoutParams(columnWidth, 100)); ret.setBackgroundColor(Color.WHITE); } else { ret= convertView; } return ret; } } } &lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:background="#FF0000" android:layout_width="match_parent" android:layout_height="match_parent"&gt; &lt;GridView android:id="@+id/grid" android:background="#00FF00" android:layout_centerInParent="true" android:layout_width="wrap_content" android:layout_height="wrap_content" android:numColumns="auto_fit" android:verticalSpacing="2dip" android:horizontalSpacing="2dip" android:stretchMode="columnWidth" android:gravity="center"&gt; &lt;/GridView&gt; &lt;/RelativeLayout&gt; </code></pre> <p><img src="https://i.stack.imgur.com/whRJb.png" alt="enter image description here"></p>

An individual column

Larger individual text columns get their own page to allow for proper reading.
