    <p>First of all, I hope you understand my English, because I'am not a native speaker. </p> <p>Okay, I am new to Android development and I'm trying following for in app: I need a <code>SeekBar</code>, so I created a <code>Seekbar</code> via XML and implemented an <code>OnSeekBarChangeListener</code>. </p> <p>In the company I work for, it's forbidden (because of the <code>styleguid</code>) to create something like this:</p> <pre><code>seekbar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() { @Override public void onProgressChanged(SeekBar arg0, int arg1, boolean arg2) { /// Do something } ... }); </code></pre> <p>So I need to create my own class for the <code>OnSeekBarChangeListener</code>. So far no problem.</p> <pre><code>public class SeekBarChangeListener extends OnSeekBarChangeListener { public SeekBarChangeListener(Context context) { super(context); } public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) { } public void onStartTrackingTouch(SeekBar seekBar) { } public void onStopTrackingTouch(SeekBar seekBar) { /// Do something. Following Code wont work CheckBox RemeberUsername = (CheckBox)findViewById(R.id.RemeberUsername); /// Always gets NULL } } </code></pre> <p>I need a way to get access to some controls. Normally, the <code>findViewById</code> works fine, but not in this case: something that I can totally understand, because how should the listener know about the views?</p> <p>Do you have good hints? </p> <p>Or is there no other way like the first code snippet to get the controls? </p> <p>Hope someone can help me out.</p>

    2. COI will use the slider to show some more options or not. SeekBar can only be 0 oder max (handeld by the Listener) and if the Seekbar is 0 some checkboxes will not be availible (because they dont make sense then). If the SeekBar is max the checkboxes should be availible. Hope its Exactly engouh?

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.
