我正在尝试在 SherlockFragment 中实现自定义 ExpandableListView。我按照这个示例扩展了 BaseExpandableListAdapter 并创建了我的自定义适配器。

这是我的问题，当我的可扩展列表显示在屏幕上时，我可以看到所有组项目，但是当我单击其中一个时，应该显示在其下方的子项目不会显示。

  1. 我尝试调试它，我放在适配器中的 onGroupExpandListener 从未被调用，实际上我在适配器的不同方法中放置了断点，当我单击其中一个组项时从未调用过。

  2. 我尝试修改定义组项和子项的 xml 文件，以使它们可单击或可聚焦，但没有任何改变。我还尝试删除我放在那里的editText，Button和CheckBox，认为这可能会造成冲突......

  3. 我认为问题可能是由于使用带有 SherlockFragment 的 ExpandableListView 的一些不兼容问题，但根据开发人员的论坛，它不是。

所以我现在真的不知道在哪里看，这可能只是我在适配器中犯的一个菜鸟错误......任何帮助都会很棒，

提前致谢！

这是我的代码：

public class BuildingExpandalbeListAdapter extends BaseExpandableListAdapter {

private Context mContext;
private ExpandableListView mExpandableListView;
private SideEntity[] mSidesCollection;
private int[] groupStatus;

public BuildingExpandalbeListAdapter(Context pContext,
        ExpandableListView pExpandableListView,
        SideEntity[] pSidesCollection) {
    mContext = pContext;
    mSidesCollection = pSidesCollection;
    mExpandableListView = pExpandableListView;
    groupStatus = new int[mSidesCollection.length];
    mExpandableListView.setClickable(true);     
    setListEvent();
}

private void setListEvent() {

    mExpandableListView
            .setOnGroupExpandListener(new OnGroupExpandListener() {

                @Override
                public void onGroupExpand(int arg0) {
                    // TODO Auto-generated method stub
                    groupStatus[arg0] = 1;
                }
            });

    mExpandableListView
            .setOnGroupCollapseListener(new OnGroupCollapseListener() {

                @Override
                public void onGroupCollapse(int arg0) {
                    // TODO Auto-generated method stub
                    groupStatus[arg0] = 0;
                }
            });
}

@Override
public Object getChild(int groupPosition, int childPosition) {
    return mSidesCollection[groupPosition].getSegmentEntity(childPosition)
            .getName();
}

@Override
public long getChildId(int groupPosition, int childPosition) {
    return mSidesCollection[groupPosition].getSegmentEntity(childPosition)
            .getId();
}

@Override
public View getChildView(int groupPosition, int childPosition,
        boolean isLastChild, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
    ChildHolder childHolder;
    if (convertView == null) {
        convertView = LayoutInflater.from(mContext).inflate(
                R.layout.building_list_item, null);

        childHolder = new ChildHolder();

        childHolder.editText1 = (EditText) convertView
                .findViewById(R.id.editText1);
        childHolder.checkBox1 = (CheckBox) convertView
                .findViewById(R.id.checkBox1);
        convertView.setTag(childHolder);
    } else {
        childHolder = (ChildHolder) convertView.getTag();
    }

    childHolder.editText1.setText(mSidesCollection[groupPosition]
            .getSegmentEntity(childPosition).getName());
    childHolder.checkBox1.setChecked(mSidesCollection[groupPosition]
            .getSegmentEntity(childPosition).hasDoor());
    return convertView;
}

@Override
public int getChildrenCount(int groupPosition) {
    // TODO Auto-generated method stub
    return mSidesCollection[groupPosition].getSegmentsCollection().size();
}

@Override
public Object getGroup(int groupPosition) {
    // TODO Auto-generated method stub
    return mSidesCollection[groupPosition];
}

@Override
public int getGroupCount() {
    // TODO Auto-generated method stub
    return mSidesCollection.length;
}

@Override
public long getGroupId(int groupPosition) {
    // TODO Auto-generated method stub
    return groupPosition;
}

@Override
public View getGroupView(int groupPosition, boolean isExpanded,
        View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
    GroupHolder groupHolder;
    if (convertView == null) {
        convertView = LayoutInflater.from(mContext).inflate(
                R.layout.building_list_group, null);
        groupHolder = new GroupHolder();
        groupHolder.editText1 = (EditText) convertView
                .findViewById(R.id.editText1);
        groupHolder.editText2 = (EditText) convertView
                .findViewById(R.id.editText2);
        convertView.setTag(groupHolder);
    } else {
        groupHolder = (GroupHolder) convertView.getTag();
    }

    groupHolder.editText1
            .setText(mSidesCollection[groupPosition].getName());
    groupHolder.editText2.setText(Integer
            .toString(mSidesCollection[groupPosition]
                    .getSegmentsCollection().size()));

    return convertView;
}

class GroupHolder {
    EditText editText1;
    EditText editText2;
}

class ChildHolder {
    EditText editText1;
    CheckBox checkBox1;
}

@Override
public boolean hasStableIds() {
    // TODO Auto-generated method stub
    return true;
}

@Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
    // TODO Auto-generated method stub
    return true;
}

}

这是我使用此适配器的 SherlockFragment ：

public class BuildingFragment extends SherlockFragment {

private ViewGroup myViewGroup;
private View v;
private SideEntity[] mSideCollection;

private BuildingsDbAdapter buildingDataBase;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    if (container == null) {
        return null;
    }
    myViewGroup = container;
    myViewGroup.removeAllViews();
    v = inflater.inflate(R.layout.building_data_layout, container, false);
    buildingDataBase = new BuildingsDbAdapter(getSherlockActivity());
    return v;
}

@Override
public void onResume() {
    super.onResume();
    buildingDataBase.open();
    mSideCollection = BuildingsDbAdapter
            .fetchSideMatchingBuildingId(CustomTabFragmentActivity.mBuildingId);
    for (int i = 0; i < mSideCollection.length; i++) {
        BuildingsDbAdapter.fetchSegmentMatchingSideId(
                mSideCollection[i].getId(), mSideCollection[i]);
    }
    ExpandableListView mExpandableListView = (ExpandableListView) v
            .findViewById(R.id.expandableListView1);
    BuildingExpandalbeListAdapter mAdapter = new BuildingExpandalbeListAdapter(
            v.getContext().getApplicationContext(), mExpandableListView,
            mSideCollection);
    mExpandableListView.setAdapter(mAdapter);
    buildingDataBase.close();
}
}

好的，我发现我的错误，问题实际上来自 EditText 和我在组项目中使用的 Button。当我将此小部件设置为不可点击和不可聚焦时，对我的组项目的点击正常执行。

我应该早点检测到这个冲突，我之前尝试删除我的 Button 和我的 EditText，但我忘记了在某些时候我曾尝试添加android:clickable="true"到我的 RelativeLayout（认为它会允许点击我的组项目），而是它也造成了冲突：/无论如何，如果有人有类似的问题，请记住检查您的组项目中的任何视图是否可点击或可聚焦并将它们设置为android:clickable="false" android:focusable="false"
