Question

I am a new bee to android.

I am working with ExpandableListViewAdapter and facing a problem.

The onChildClickListener is not working when I click on the edit text box.

My question is will it work on edit text box or not.

I am implementing the BaseExpandableListAdapter.

Thanks in advance.

public class TryExpandableListViewActivity extends Activity implements     OnChildClickListener {

LinearLayout llayout;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    llayout = (LinearLayout) findViewById(R.id.llayout);

    ExpandableListView list = new ExpandableListView(this);
    list.setGroupIndicator(null);
    list.setChildIndicator(null);
    String[] titles = {"A","B","C"};
    String[] fruits = {"a1","a2"};
    String[] veggies = {"b1","b2","b3"};
    String[] meats = {"c1","c2"};
    String[][] contents = {fruits,veggies,meats};
    SimplerExpandableListAdapter adapter = new SimplerExpandableListAdapter(this,titles, contents);

    list.setAdapter(adapter);

    llayout.addView(list);

    list.setOnChildClickListener(this);
}

@Override
public boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id) {
    Log.i("Test","-------------------------------------------");
    return false;
}

}

class SimplerExpandableListAdapter extends BaseExpandableListAdapter {

private Context mContext;
private String[][] mContents;
private String[] mTitles;

public SimplerExpandableListAdapter(Context context, String[] titles, String[][] contents) {
    super();
    if(titles.length != contents.length) {
      throw new IllegalArgumentException("Titles and Contents must be the same size.");
    }
    mContext = context;
    mContents = contents;
    mTitles = titles;

  }

@Override
public Object getChild(int groupPosition, int childPosition) {
    return mContents[groupPosition][childPosition];
}

@Override
public long getChildId(int groupPosition, int childPosition) {
    return 0;
}

@Override
public View getChildView(int groupPosition, int childPosition,
    boolean isLastChild, View convertView, ViewGroup parent) { 

        EditText row = (EditText)convertView;
        if(row == null) {
          row = new EditText(mContext);
        }
        row.setTypeface(Typeface.DEFAULT_BOLD);
        row.setText(mContents[groupPosition][childPosition]);
        return row;

}

@Override
public int getChildrenCount(int groupPosition) {
    return mContents[groupPosition].length;
}

@Override
public Object getGroup(int groupPosition) {
    return mContents[groupPosition];
}

@Override
public int getGroupCount() {
    return mContents.length;
}

@Override
public long getGroupId(int groupPosition) {
    return 0;
}

@Override
public View getGroupView(int groupPosition, boolean isExpanded,
    View convertView, ViewGroup parent) {
    TextView row = (TextView)convertView;
    if(row == null) {
      row = new TextView(mContext);
    }
    row.setTypeface(Typeface.DEFAULT_BOLD);
    row.setText(mTitles[groupPosition]);
    return row;
}

@Override
public boolean hasStableIds() {
    return false;
}

@Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
    return true;
}

}

Without seeing code this is just a guess but the childCLickListener may be consuming the event so its not reaching the edit text, try returning false in childClickListener

Edit

Okay I just created a small project with your code and I couldn’t get the onCildClickListener to fire, changing it to a TextView and it works fine. Its something to do with the EditText (perhaps its consuming the event or its not registering as a click but as a change in focus but I’m just guessing at this point).

So in answer to your question, is it possible – I don’t think so. But I did make a small workaround that may be of use.

Attach an onTouchListener() to the EditText and check for MotionEvent.ACTION_DOWN
