适配器

 public class ExpandableListAdapter extends BaseExpandableListAdapter {

private Context mContext;
private ExpandableListView mExpandableListView;
private List <Grupe> mGroupCollection;
private int[] groupStatus;


public ExpandableListAdapter() {}
public ExpandableListAdapter(Context pContext,
ExpandableListView pExpandableListView,
List <Grupe> pGroupCollection) {

setListEvent();
}

private void setListEvent() {

.setOnGroupExpandListener(new OnGroupExpandListener() {
@Override
public void onGroupExpand(int arg0) {

@Override
public void onGroupCollapse(int arg0) {

}
});
}

@Override
public String getChild(int arg0, int arg1) {
return mGroupCollection.get(arg0).getChildren().get(arg0).getPrimaoc_Poruke();
}

@Override
public long getChildId(int arg0, int arg1) {
return 0;
}

@Override
public View getChildView(int arg0, int arg1, boolean arg2, View arg3,
ViewGroup arg4) {

ChildHolder childHolder;
if (arg3 == null) {
arg3 = LayoutInflater.from(mContext).inflate(

}

return arg2;
}

}

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

@Override

主 Activity

 public class Glavna extends Activity implements OnClickListener, OnChildClickListener {

private List <Grupe> mGroupCollection;
private ExpandableListView mExpandableListView;
private ExpandableListAdapter adapter = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_glavna);
prepareResource();
initPage();
}

private void initPage() {
mExpandableListView = (ExpandableListView) findViewById(R.id.expandableListView1);
adapter = new ExpandableListAdapter(this,mExpandableListView, mGroupCollection);
mExpandableListView.setAdapter(adapter);
mExpandableListView.setOnChildClickListener(this);

}

private void prepareResource() {
mGroupCollection = new ArrayList <Grupe> ();
ge.setTip("Online korisnici");
mGroupCollection.add(ge);

AktivniChat gi = new AktivniChat(1, "receiver 1", new Korisnik(1, "sender1"));
mGroupCollection.get(0).setAktivniChat(gi);
}

@Override
public boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id) {
return true;
}
}

最佳答案

在所有元素上设置android:focusable="false"

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:baselineAligned="false"
android:paddingTop="5dip"
android:focusable="false">

<LinearLayout
android:id="@+id/groupItem"
android:layout_width="0dip"
android:layout_height="fill_parent"
android:layout_weight="1"
android:background="#FFF385"
android:clickable="false"
android:focusable="false">

<TextView
android:id="@+id/item_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#FF84"
android:clickable="false"
android:focusable="false"
android:focusableInTouchMode="false"
android:text="sample"
android:textColor="#000000"
android:textSize="20sp" />

</LinearLayout>

</LinearLayout>
