    <p>I am drawing some rows of text. After a couple of rows, it goes offscreen. What i want to do is capture all the rows(also the rows outside the canvas) in a bitmap.</p> <pre><code>I have the code below which only works for within the canvas(screen). private class DeciderView extends View { private Paint paint; String text = ""; String[] options = { "een", "twee", "drie", "vier", "vijf", "zes", "zeven", "acht", "negen", "tien", "elf", "twaalf", "dertien", "vertien", "vijftien" }; public DeciderView(Context context) { super(context); // Keep screen on getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); // Remove title bar requestWindowFeature(Window.FEATURE_NO_TITLE); // Remove notification bar getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); this.setBackgroundColor(Color.WHITE); paint = new Paint(); paint.setTextSize(75); paint.setColor(Color.BLACK); paint.setStrokeWidth(10); paint.setAntiAlias(true); setDrawingCacheEnabled(true); setDrawingCacheQuality(DRAWING_CACHE_QUALITY_HIGH); } private void drawInput(Canvas canvas) { Paint p = new Paint(); p.setTextAlign(Align.CENTER); p.setTextSize(canvas.getWidth() / 10f); p.setColor(Color.BLACK); float xText = canvas.getWidth() / 2f; float yText = (canvas.getHeight() / 4f); for (int i = 0; i &lt; options.length; i++) { text += options[i] + "\n"; } for (String line : text.split("\n")) { canvas.drawText(line, xText, yText, p); yText -= (p.ascent() + p.descent()) * 2.5f; } } @Override public void onDraw(Canvas canvas) { drawInput(canvas); this.setDrawingCacheEnabled(true); Bitmap b = Bitmap.createBitmap(this.getDrawingCache()); b = Bitmap.createScaledBitmap(b, canvas.getWidth(), canvas.getHeight(), false); try { b.compress(Bitmap.CompressFormat.JPEG, 100, new FileOutputStream( new File(Environment.getExternalStorageDirectory().getPath() + "/Pictures/aaaaa.jpg"))); } catch (FileNotFoundException e) { e.printStackTrace(); } if (b != null) { b.recycle(); b = null; } } } </code></pre> <p>So basically i want to make a bitmap from all the rows, even if the rows are drawn outside the canvas.</p>

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.
