java.lang.NullPointerException    at android.widget.ArrayAdapter.createViewFromResource(ArrayAdapter.java:394)ArrayAdapter<Comment> adapter =     new ArrayAdapter<Comment>(this, android.R.layout.simple_list_item_1, values);

values

您可以通读源代码，并在此处看到这种情况：

T item = getItem(position);if (item instanceof CharSequence) {    text.setText((CharSequence)item);} else {    text.setText(item.toString()); // Line 394, when item is null this throws an NPE}
