    <p>I've created a class which extends Android's Text view. I'm trying to to center the text horizontally and vertically. The text appears to center horizontally but not vertically.</p> <p>I've tried both:</p> <pre><code>setGravity(Gravity.CENTER); </code></pre> <p>and</p> <pre><code>setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL); </code></pre> <p>My class is below:</p> <pre><code>public class NumberView extends TextView { private Paint circlePaint; private int radius; public NumberView(Context context) { super(context); setText("0"); circlePaint = new Paint(); circlePaint.setColor(Color.BLUE); // setGravity(Gravity.CENTER); setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL); setBackgroundColor(Color.rgb(0xf1, 0xf1, 0xf1)); setTypeface(null, Typeface.BOLD); setTextSize(TypedValue.COMPLEX_UNIT_SP, 15); } @Override protected void onDraw(Canvas canvas) { // draw circle at center of canvas super.onDraw(canvas); int width = getWidth(); int height = getHeight(); radius = Math.min(width, height); radius /= 2; canvas.drawCircle(width/2, height/2, radius, circlePaint); //super.onDraw(canvas); } </code></pre> <p>}</p> <p>I'm adding NumberView as part of a ExpandableList View. Down below is how I had the expandable list view to the layout:</p> <pre><code> listView = new ExpandableListView(this); listView.setAdapter(listAdapter); TextView emptyView = new TextView(this); listView.setEmptyView(emptyView); mainLayout.addView(listView, new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT , 2)); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
