我有一个可扩展的 ListView ,当我点击一行时,它会触发 onChildClickonGroupClick,具体取决于我点击的是子项还是组。

enter image description here

如果我在 xml 布局文件中添加可点击的内容(例如复选框),onChildClick 将不再触发。 (如果我添加一个简单的 textView 它也可以工作)

the child_layout

谁知道为什么?该项目是否覆盖了监听器?

主要代码:

     View firstView = inflater.inflate(R.layout.main_layout, container, false);
listView = (ExpandableListView) firstView.findViewById(R.id.expandableListView1);
listView.setOnChildClickListener(new OnChildClickListener()
{

@Override
public boolean onChildClick(ExpandableListView arg0, View arg1, int arg2, int arg3, long arg4)
{
Toast.makeText(getActivity().getBaseContext(), "Child clicked", Toast.LENGTH_LONG).show();
return false;
}
});

适配器代码:

public class ExpandableListAdapter extends BaseExpandableListAdapter {

private Context context;

private ArrayList<String> groups;

private ArrayList<ArrayList<FarmaciListItem>> children;

public ExpandableListAdapter(Context context, ArrayList<String> groups,
ArrayList<ArrayList<FarmaciListItem>> children) {
this.context = context;
this.groups = groups;
this.children = children;
}

@Override
public Object getChild(int groupPosition, int childPosition) {
return children.get(groupPosition).get(childPosition);
}

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

// Return a child view. You can load your custom layout here.
@Override
public View getChildView(int groupPosition, int childPosition, boolean isLastChild,
View convertView, ViewGroup parent) {
FarmaciListItem farmacoItem = (FarmaciListItem) getChild(groupPosition, childPosition);
if (convertView == null) {
LayoutInflater infalInflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = infalInflater.inflate(R.layout.child_layout, null);
}
TextView tv = (TextView) convertView.findViewById(R.id.tvChild);
tv.setText(" " + farmacoItem.getName());

// Depending upon the child type, set the imageTextView01
tv.setCompoundDrawablesWithIntrinsicBounds(0, 0, 0, 0);
if (farmacoItem instanceof PesoItem) {
tv.setCompoundDrawablesWithIntrinsicBounds(R.drawable.car, 0, 0, 0);
}
return convertView;
}

@Override
public int getChildrenCount(int groupPosition) {
return children.get(groupPosition).size();
}

@Override
public Object getGroup(int groupPosition) {
return groups.get(groupPosition);
}

@Override
public int getGroupCount() {
return groups.size();
}

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

// Return a group view. You can load your custom layout here.
@Override
public View getGroupView(int groupPosition, boolean isExpanded, View convertView,
ViewGroup parent) {
String group = (String) getGroup(groupPosition);
if (convertView == null) {
LayoutInflater infalInflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = infalInflater.inflate(R.layout.group_layout, null);
}
TextView tv = (TextView) convertView.findViewById(R.id.tvGroup);
tv.setText(group);
return convertView;
}

最佳答案

问题是因为您的 child 身上有可聚焦的元素。例如考虑一个按钮,默认情况下它将处于聚焦状态。所以将它设置为 false 就可以了。

在你的情况下,也许为复选框添加以下属性

  android:focusable="false"

这应该可以解决问题。
