    <p>I have writing a mediaplayer app. When clicked on the play list button, ExpandList Activity launches and depending on which child is clicked, it should start my main activity and return the childposition. But it doenst do anything. There is no error or anything. It seems like its not even going into the onChildClick method and I am not sure why. I have looked at many examples and they all seem to have it the same why I have it. I was hoping someone could point out what I am doing wrong. Here is my code below. Thank you</p> <pre><code>import java.util.ArrayList; import android.app.ExpandableListActivity; import android.content.Context; import android.content.Intent; import android.os.Bundle; import android.util.Log; import android.view.LayoutInflater; import android.view.View; import android.widget.ExpandableListView; import android.widget.ExpandableListView.OnChildClickListener; import android.widget.Toast; public class ExpandListActivity extends ExpandableListActivity implements OnChildClickListener { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ExpandableListView expandbleLis = getExpandableListView(); expandbleLis.setDividerHeight(2); expandbleLis.setGroupIndicator(null); expandbleLis.setClickable(true); expandbleLis.setOnChildClickListener(this); setGroupData(); setChildGroupData(); NewAdapter mNewAdapter = new NewAdapter(groupItem, childItem); mNewAdapter .setInflater( (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE), this); expandbleLis.setAdapter(mNewAdapter); } public void setGroupData() { groupItem.add("TechNology"); groupItem.add("Mobile"); groupItem.add("Manufacturer"); groupItem.add("Extras"); } ArrayList&lt;String&gt; groupItem = new ArrayList&lt;String&gt;(); ArrayList&lt;Object&gt; childItem = new ArrayList&lt;Object&gt;(); public void setChildGroupData() { /** * Add Data For TecthNology */ ArrayList&lt;String&gt; child = new ArrayList&lt;String&gt;(); child.add("Java"); child.add("Drupal"); child.add(".Net Framework"); child.add("PHP"); childItem.add(child); /** * Add Data For Mobile */ child = new ArrayList&lt;String&gt;(); child.add("Android"); child.add("Window Mobile"); child.add("iPHone"); child.add("Blackberry"); childItem.add(child); /** * Add Data For Manufacture */ child = new ArrayList&lt;String&gt;(); child.add("HTC"); child.add("Apple"); child.add("Samsung"); child.add("Nokia"); childItem.add(child); /** * Add Data For Extras */ child = new ArrayList&lt;String&gt;(); child.add("Contact Us"); child.add("About Us"); child.add("Location"); child.add("Root Cause"); childItem.add(child); } @Override public boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id) { Toast.makeText(ExpandListActivity.this, "Clicked On Child", Toast.LENGTH_SHORT).show(); // Starting new intent Intent in = new Intent(getApplicationContext(), AndroidBuildingMusicPlayerActivity.class); // Sending childPosition to PlayerActivity in.putExtra("childPosition", childPosition); Log.println(0, getClass().getName(), "onChildClick inside"); setResult(100, in); startActivity(in); // Closing PlayListView finish(); return true; } } </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.
