    <p>I have a big problem. I have a activity where I have two imageViews. In onCreate I have List pictures where I have 10 pictures. Every time when I start this activity both imageViews get random picture from List and shows them. For example: When I start activity I can see car and pencil and when I start this activity once again I get elephant and book. Now this is my problem. When I start activity and block my phone and after that unlock I get other pictures. I think that onCreate is called again. I create </p> <pre><code>@Override protected void onSaveInstanceState(Bundle savedInstanceState) { super.onSaveInstanceState(savedInstanceState); } public void onRestoreInstanceState(Bundle savedInstanceState) { if (savedInstanceState != null) { pictureGameLeft.setImageResource(shapesPictures.get(game.getCurrentLevel().getCurrentPair().getImageLeft())); pictureGameRight.setImageResource(shapesPictures.get(game.getCurrentLevel().getCurrentPair().getImageRight())); } } </code></pre> <p>pictureGameLeft and Right that is last images which is shows. I write them after onCreate method. How I can save last seen picture that if I lock and unlock phone I get the same pictures. Maybe onPause or onStop need called? </p> <p>edit: now: </p> <pre><code>if (savedInstanceState == null) { game = new Game(); game.initGame(); addElements(result); game.getCurrentLevel().nextPair(); pictureGameLeft.setImageResource(shapesPictures.get(game.getCurrentLevel().getCurrentPair() .getImageLeft())); pictureGameRight.setImageResource(shapesPictures.get(game.getCurrentLevel().getCurrentPair() .getImageRight())); mRedrawHandler.sleep(1000); } else { pictureGameLeft.setImageResource(shapesPictures.get(game.getCurrentLevel().getCurrentPair( .getImageLeft())); pictureGameRight.setImageResource(shapesPictures.get(game.getCurrentLevel().getCurrentPair() .getImageRight())); } </code></pre> <p>but I get NullPointerException.</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.
