使可扩展列表视图的单击侦听器工作时遇到问题。我是否正确地执行了这一点?
代码:

elv = getExpandableListView();

// Set up the adapter
mAdapter = new MyExpandableListAdapter();
elv.setAdapter(mAdapter);

elv.setOnChildClickListener(new OnChildClickListener() {

        public boolean onChildClick(ExpandableListView parent, View v,
                int groupPosition, int childPosition, long id) {
            Toast.makeText(getApplicationContext(), "click", Toast.LENGTH_SHORT);
            v.setBackgroundColor(0x000000);
            return false;
        }
    });

最佳答案

您尚未在吐司消息中调用show()。所以,如果你决定它是否只对祝酒词起作用,它似乎就不起作用了。add.show();在创建吐司的行的末尾,它应该出现
