Question

似乎给出异常的代码如下：

Snackbar.make(findViewById(R.id.content_main), "E' necessario abilitare il GPS per aggiornare la lista", Snackbar.LENGTH_INDEFINITE)
        .setAction("ATTIVA", new View.OnClickListener() {

             @Override
             public void onClick(View v) {

                Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                startActivity(intent);
             }
}).show();

我这样说是因为我尝试调试应用程序，它只能删除这部分代码。

这里是错误日志：

我使用ArrayList的唯一时刻是我初始化它时：

ArrayList<CustomLVArray> retrievedData;
ListAdapter listAdapter;
ListView listView;

....

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    ....

    retrievedData = new ArrayList<>();
    listView = (ListView) findViewById(R.id.content_main);

    listAdapter = new CustomListViewAdapter(this, retrievedData);
    listView.setAdapter(listAdapter);

    listView.setOnScrollListener....

当我添加东西时：

CustomLVArray message = new CustomLVArray("Title", "subtitle", "Lorem ipsum dolor sit amet ipsum dolor sit amet ipsum dolor sit amet ipsum dolor sit amet", getResources().getDrawable(R.drawable.ic_menu_camera));

        retrievedData.clear();

        for (int i = 0; i <= 10; i++) {

            retrievedData.add(message);
        }

似乎实现了第一个答案中解释的“技巧”：ArrayIndexOutOfBoundsException while dismissing Snackbar/ViewDragHelper应用程序不会崩溃。

有谁知道为什么会这样？

Android：Snackbar提供ArrayIndexOutOfBoundsException
