I want to draw on canvas month's text vertical along screen height. Paint init: <pre class="lang-java prettyprint-override"><code> this.paint = new Paint(); this.paint.setAntiAlias(true); this.paint.setDither(true); this.paint.setSubpixelText(true); this.paint.setColor(color_text_dark); this.paint.setTextAlign(Align.RIGHT); </code></pre> Drawing: <pre class="lang-java prettyprint-override"><code> // Set the scale to the widest month float scale = getHeight() / this.max_month_width; String month_string = FULL_MONTH_NAME_FORMATTER. format(active_month_calendar.getTime()); canvas.save(); canvas.translate(getWidth(), 0); canvas.rotate(-90); canvas.scale(scale, scale); canvas.drawText(month_string, 0, 0, this.paint); canvas.restore(); </code></pre> <s>Result looks good on hdpi screen, but very ugly and pixelated on xhdpi one.</s> I did more test on various devices, and understood what result depends on Android version, not screen density and resolution. Code works fine on 2.x platform, but doesn't work on 4.0.3+. Suppose, Android draw implementation was changed here. Full code you can see <a href="https://github.com/openintents/openintents/blob/master/calendarpicker/CalendarPicker/src/org/openintents/calendarpicker/view/FlingableMonthView.java" rel="nofollow noreferrer">here</a>. <s>hdpi</s> version 2.3.5 (also tested 2.2) <img src="https://i.stack.imgur.com/v4FpY.png" alt="hdpi"> <s>xhdpi</s> version 4.2 (also tested 4.1, 4.0.3) <img src="https://i.stack.imgur.com/hZ09G.png" alt="xhdpi"> Trying different variations for paint antialias, subpixel text has no effect. How can I fix this issue?

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.
