Question

不确定为什么我的onChildClick没有触发。一切都很完美，除了当其中一个儿童用品被敲击时，绝对没有任何反应。否则，可扩展组按预期工作。问题是程序永远不会进入onChildClick（）事件处理程序。有什么想法吗？

MainActivity.java

public class MainActivity extends AppCompatActivity {

private ExpandableListView mBrandsListView;
HashMap<String, ArrayList<DataInfoTivi>> expandableListDetail;
private ExpandableListAdapter mBrandAdapter;
List<String> expandableListTitle;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mBrandsListView = (ExpandableListView) findViewById(R.id.list_brands);
    expandableListDetail = ExpandableListDataPump.getData();
    expandableListTitle = new ArrayList<String>(expandableListDetail.keySet());
    mBrandAdapter = new BrandAdapter(this,expandableListTitle ,expandableListDetail);
    mBrandsListView.setAdapter(mBrandAdapter);

    mBrandsListView.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
        @Override
        public boolean onChildClick(final ExpandableListView parent, final View v, final int groupPosition, final int childPosition, final long id) {
            Log.e("Click ne","buc ghe");
            return false;
        }
    });

    for (int i = 0; i < mBrandAdapter.getGroupCount(); i++) {
        mBrandsListView.expandGroup(i);
    }
}
