    <p>I have an array of drawables, that I would like to change by my own timer to a imageview. (i tried the other option with xml and setBackgroundResource, but does not work for me as I have hundret of pics and always got memory problem as it looks android assign already the whole memory for all pics at once. (just in this demo i shorted it to 4 images)</p> <p>Ok, so first i make my array</p> <pre><code>private static int[] draws = { R.drawable.frankiearmevor_0001, R.drawable.frankiearmevor_0002, R.drawable.frankiearmevor_0003, R.drawable.frankiearmevor_0002 }; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); imgView = (ImageView) findViewById(R.id.fredi); // create timer Timer updateProgressTimer = new Timer(); updateProgressTimer.scheduleAtFixedRate(new TimerTask() { @Override public void run() { myloop(); } }, 0, 150); } int mycounter; public void myloop() { mycounter++; if (mycounter &gt; 4) mycounter = 1; imgView.setImageResource(draws[mycounter-1]); String hallo; hallo = "now: "+mycounter; Log.d("1",hallo); } </code></pre> <p>when I assign only a fixed image: imgView.setImageResource(draws[2]); it shows that fine and I see also my thread is logged fine, but when I exchange the fixed resource draws[2] into a dynamic draws[mycounter-1] .. i just get a black screen, no error, nothing.</p> <p>what to do, so i will show the images :)</p> <p>thx chris</p> <p>EDIT: 22. August:</p> <p>I tried now with the comment I got, it compiles fine, but somehow there is an error i guess.. it crash:</p> <pre><code> imgView = (ImageView) findViewById(R.id.fredi); Timer updateProgressTimer = new Timer(); updateProgressTimer.scheduleAtFixedRate(new TimerTask() { @Override public void run() { //myloop(); imgView.post (new Runnable() { public void run() { mycounter++; if (mycounter &gt; 10) mycounter = 1; imgView.setImageResource(draws[1]); //imgView.invalidate(); String hallo; hallo = "now: "+mycounter; Log.d("1",hallo); } }); } }, 0, 150); </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.
