Android onChildClick未打开活动

大家早上好。onChildClick侦听器未打开新活动。尝试使用开关，现在使用if语句，但仍然没有成功。我确实将活动添加到清单中，但仍然没有运气。谢谢你的帮助

活动

                    startActivity(a1);
                    Log.e("MY TAG", "child clicked");

ExpandableListView

  ...
  setContentView(R.layout.expandable_main);
  lv = (ExpandableListView) findViewById(R.id.your_list_id);

我不确定这一点，但在ExpActivity中的代码中没有这一行

 lv = (ExpandableListView)findViewById(R.id.lv_item);

试试这个：

如果不解决的话。您可以发布您得到的行日志的错误。
您试过调试它吗？也就是说，在侦听器中的
if块
之外放置一个日志？在你的问题中张贴日志。这是至关重要的信息。我不知道除了作为文本之外，如何添加LogaCat。希望这有帮助。谢谢。你的应用程序崩溃了吗？这看起来不像是来自应用程序的错误，而是来自android系统的错误。在你的
onChildClick
方法中放入一个
Log.e（“，”test”）
，看看它是否被打印出来。应用程序没有崩溃，我有一个日志语句，但没有打印出来。这不起作用，我在日志猫上看到的唯一错误是SoundPool，AudioService刚才乔纳森·佩雷斯
 lv = (ExpandableListView)findViewById(R.id.lv_item);
