    <p>Welcome. I have a problem. I want to do dynamic wallpaper so that every few seconds to change the text. The program works pretty well because the text is changing, but changing so that the previous text is still visible, and after a few seconds I have a lot of the text. I looked everywhere but I am a beginner and do not know how to solve that problem. There is a code:</p> <pre><code>private class MyWallpaperEngine extends Engine { private final Handler handler = new Handler(); private final Runnable drawRunner = new Runnable() { @Override public void run() { draw(); } }; private Paint paint = new Paint(); private int width; int height; private boolean visible = true; public MyWallpaperEngine() { paint = new Paint(); paint.setAntiAlias(true); paint.setColor(Color.WHITE); handler.post(drawRunner); } @Override public void onVisibilityChanged(boolean visible) { this.visible = visible; if (visible) { handler.post(drawRunner); } else { handler.removeCallbacks(drawRunner); } } @Override public void onSurfaceDestroyed(SurfaceHolder holder) { super.onSurfaceDestroyed(holder); this.visible = false; handler.removeCallbacks(drawRunner); } @Override public void onSurfaceChanged(SurfaceHolder holder, int format, int width, int height) { this.width = width; this.height = height; super.onSurfaceChanged(holder, format, width, height); } private void draw() { SurfaceHolder holder = getSurfaceHolder(); Canvas canvas = null; try { canvas = holder.lockCanvas(); if (canvas != null) drawAnimation(canvas); } finally { if (canvas != null) holder.unlockCanvasAndPost(canvas); } if (visible) { handler.postDelayed(drawRunner, 4000); } } private void drawAnimation(Canvas c){ Random r = new Random(); int i1=r.nextInt(200-50) + 50; String text = Integer.toString(i1); c.drawText(text, i1, i1, paint); } } </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.
