我正在努力处理这段代码，每次我运行它时它都会崩溃，所以我回到正常状态，在那里我完成了自定义适配器并将它连接到 ListView ，程序运行得非常好， 然后我尝试添加一个 Intent 以在您单击列表中的项目时打开另一个 Activity 我也添加了一个额外的内容来从主要 Activity 发送数据以查看存储在 stings 中的文本列表， 在我完成所有这些并且一切顺利之前，我尝试添加一个自定义 View 。这是我的代码。

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {

Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();

您好，在这种情况下，您必须序列化数据，然后将它们传递给另一个 Activity 。 请检查以下链接。
