长按阻止扩展可扩展列表视图

Question

我正在开发一个 android 应用程序，我在其中使用 Expandablelistview 来显示一些数据。目前，列表视图将在点击组和长按后释放时展开。但是，我需要防止在长按时展开 Expandablelistview。

我的代码段如下所示：

elvItemList = (ExpandableListView) root.findViewById(R.id.elv_item_list);
elvItemList.setOnGroupClickListener(this);
elvItemList.setAdapter(smListAdapter);
elvItemList.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
    @Override
    public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
        if (ExpandableListView.getPackedPositionType(id) == ExpandableListView.PACKED_POSITION_TYPE_GROUP) {
            Utils.logit("SMLOG", "Long button pressed");
            //
        }
        return false;
    }
});

谁能帮帮我？

Answer 1

ExpandableListView.PACKED_POSITION_TYPE_GROUP是群的id，改成 ExpandableListView.PACKED_POSITION_TYPE_CHILD 您可以通过长按子组进行操作。

类似的东西：

elvItemList.setOnItemLongClickListener(new OnItemLongClickListener() {
@Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
if (ExpandableListView.getPackedPositionType(id) == ExpandableListView.PACKED_POSITION_TYPE_CHILD) {
// Your code with group long click
return true;
}
return false;
}
});

public void stopExpandOnLongClick()
{
    expListView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
        @Override
        public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
            boolean checkClick=false;
            long packedPosition = expListView.getExpandableListPosition(position);

            int itemType = ExpandableListView.getPackedPositionType(packedPosition);
            int groupPosition = ExpandableListView.getPackedPositionGroup(packedPosition);

             /*  if group item clicked */
            if (itemType == ExpandableListView.PACKED_POSITION_TYPE_GROUP) {
                //  ...
                if(expListView.isGroupExpanded(groupPosition))
                {
                    Toast.makeText(MainActivity.this, "It's normal group collaspe", Toast.LENGTH_LONG).show();
                }
                else
                {
                    Toast.makeText(MainActivity.this, "This Grouo is not going to expand on long click", Toast.LENGTH_LONG).show();
                    //you can put your logic when you long press on Group header
                    checkClick=true;
                }
            }
            return checkClick;
        }
    });

}

这对我有用。

expandableListView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
    @Override
        public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {

            return true; // Change return false; to return true;
        }
    });
