Android 无法在listview适配器类中启动Tactivity

我想在listview项目中单击TextView并打开一个新布局

下面是我的主类、适配器类和Logcat

我尝试了3种启动Tactivity的方法，但失败了（我在下面的适配器类中对其进行了注释）

这是我的主要活动屏幕1.课堂

//add padding top - bottom for listview
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
LinearLayout header = (LinearLayout) inflater.inflate(R.layout.header, null);
lvSchedule.addFooterView(header, null, false);
lvSchedule.addHeaderView(header, null, false);
//setup listView Adapter
scheduleAdapter = new Schedule_lvAdapter(Screen1.this, R.layout.schedule_listview, scheduleLvItems);
//setup adapter to listView
lvSchedule.setAdapter(scheduleAdapter);
//setup OnClickListener
lvSchedule.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {

        int postion = i - lvSchedule.getHeaderViewsCount();
        toggle(view, postion);

    }
});

在清单文件中声明您的活动

Schedule\u Detail.class

。它可能会解决您的问题。

将此写在您的清单中

<activity name=".Schedule_Detail">
 </activity>

然后试一试。

这是一个简单的解决方案。。。 您尚未在清单文件中声明您的活动

在清单文件中写入此内容，您就得到了解决方案。

您没有在清单文件中添加

Schedule\u Detail

可能的重复项请参见此日志行：

android.content.ActivityNotFoundException:无法找到显式活动类{com.prototype.auinsight.schedual_listview/com.prototype.auinsight.schedual_listview.Schedule_Detail}；您是否在AndroidManifest.xml中声明了此活动？
