似乎导致异常的代码如下：
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();
我这么说是因为当我试图调试这个应用程序时，只有删除代码中的这一部分才能使它正常工作。
以下是错误日志:

我只在初始化时使用 ArrayList：
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....
并且当我向其添加内容时：
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);
}
