    <p>I have a problem of that how to setup seekbar to work correctly when I setProgress upon click. Progress is jumping to the beginning/middle/end depends on where I click on it. How is it possible to solve?</p> <p>That my attemps:</p> <pre><code> @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_video_player);

seekBar.setOnSeekBarChangeListener(this); .... } @Override public void onPrepared(MediaPlayer mp) { // TODO Auto-generated method stub seekBar.setMax(mp.getDuration()); System.out.println("curpos" + mp.getCurrentPosition()); new Thread(new Runnable() { public void run() { try { while (mPlayer != null &amp;&amp; mPlayer.getCurrentPosition() &lt; mPlayer.getDuration()) { seekBar.setProgress(mPlayer.getCurrentPosition()); Message msg = new Message();

Check what real position it takes when you click somewhere on the seekbar, everything correct but in one moment its position value overrides somehow.</p>

    1. COWhat do you mean by 'depending on where I click'. Are you clicking on a seekbar or a button to start playing the file ?

    2. COSorry for a bit unclear problem description, I mean when you click everywhere on the seekbar it jumps to the beginnng/middle or end of seekbar.

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).
