Question

为什么日志没有打印？所有其他人的日志都有效，但不适合孩子。

文本视图的日志确实出现，但是当我使用编辑文本时，它不起作用。

为什么这样？我哪里错了？

ExpandableListView expListView;

expListView = getExpandableListView();

expListView.setAdapter(new ExAdapter(this));

        expListView.setOnGroupExpandListener(new OnGroupExpandListener() {

            @Override
            public void onGroupExpand(int groupPosition) {
                // TODO Auto-generated method stub

            }

        });

        expListView.setOnGroupCollapseListener(new OnGroupCollapseListener() {

            @Override
            public void onGroupCollapse(int groupPosition) {
                // TODO Auto-generated method stub

            }

        });

        expListView.setOnChildClickListener(new OnChildClickListener() {

            @Override
            public boolean onChildClick(ExpandableListView parent, View v,
                    int groupPosition, int childPosition, long id) {
                Log.i("Tag", "-------------------------------------------------");
                return true;
            }

        });

代码编辑---------

    @Override
    public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {

    if(convertView == null) {
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.name_child, null);

    }

    TextView txtFName = (TextView) convertView.findViewById(R.id.txtFname);
    txtFName.setText(arrChildhintelements[groupPosition][childPosition]);


    editFName = (EditText) convertView.findViewById(R.id.editFName);
    editFName.setHint(arrChildhintelements[groupPosition][childPosition]);


    editFName.setOnTouchListener(new OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {

            //doing somthing....

            return false;
        }

    }); 

    return convertView;
}

Answer 1

没有看到代码这只是一个猜测，但是childCLickListener可能正在使用该事件，因此它没有到达编辑文本，尝试在childClickListener中返回false

修改

好吧，我刚用你的代码创建了一个小项目，我无法触发onCildClickListener，将其更改为TextView，并且工作正常。它与EditText有关（可能它正在消耗该事件或者它没有注册为点击但是作为焦点的变化，但我只是在这一点猜测。）

所以在回答你的问题时，是否有可能 - 我不这么认为。但我确实做了一个可能有用的小解决方案。

将onTouchListener（）附加到EditText并检查MotionEvent.ACTION_DOWN

Answer 3

把

myList.setOnChildClickListener(listAdapter);

你的onCreate方法中的

。

然后onChildClick方法立即开始工作。

onChildClickListener在ExpandableListView中没有响应
