    <p>Yahoo! Finally ! Works ! (BUT !!!! can cause memory leak with big images. It's fixed in the post below)</p> <p>This code takes the tile picture (tile1), repeats it(TileMode.REPEAT), makes shifted animation (10 fragments), adds this in Animation set.</p> <p><img src="https://i.stack.imgur.com/v9dLq.png" alt="enter image description here"></p> <pre><code>private void initAnimation() { // R.drawable.tile1 is PNG Bitmap b = BitmapFactory.decodeResource(getResources(),R.drawable.tile1); AnimationDrawable shiftedAnimation = getAnimation(b); // R.id.img_3 is ImageView in my application View v = findViewById(R.id.img_3); v.setBackground(shiftedAnimation); shiftedAnimation.start(); } private Bitmap getShiftedBitmap(Bitmap bitmap, int shiftX) { Bitmap newBitmap = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(), bitmap.getConfig()); Canvas newBitmapCanvas = new Canvas(newBitmap); Rect srcRect1 = new Rect(shiftX, 0, bitmap.getWidth(), bitmap.getHeight()); Rect destRect1 = new Rect(srcRect1); destRect1.offset(-shiftX, 0); newBitmapCanvas.drawBitmap(bitmap, srcRect1, destRect1, null); Rect srcRect2 = new Rect(0, 0, shiftX, bitmap.getHeight()); Rect destRect2 = new Rect(srcRect2); destRect2.offset(bitmap.getWidth() - shiftX, 0); newBitmapCanvas.drawBitmap(bitmap, srcRect2, destRect2, null); return newBitmap; } private List&lt;Bitmap&gt; getShiftedBitmaps(Bitmap bitmap) { List&lt;Bitmap&gt; shiftedBitmaps = new ArrayList&lt;Bitmap&gt;(); int fragments = 10; int shiftLength = bitmap.getWidth() / fragments; for(int i = 0 ; i &lt; fragments; ++i){ shiftedBitmaps.add( getShiftedBitmap(bitmap,shiftLength * i)); } return shiftedBitmaps; } private AnimationDrawable getAnimation(Bitmap bitmap) { AnimationDrawable animation = new AnimationDrawable(); animation.setOneShot(false); List&lt;Bitmap&gt; shiftedBitmaps = getShiftedBitmaps(bitmap); int duration = 50; for(Bitmap image: shiftedBitmaps){ BitmapDrawable navigationBackground = new BitmapDrawable(getResources(), image); navigationBackground.setTileModeX(TileMode.REPEAT); animation.addFrame(navigationBackground, duration); } return animation; } </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.

SQuiL has stopped working due to an internal error.

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