Activity.showDialog(int，Bundle)上的java.lang.NoSuchMethodError？

Question

这是 LogCat 所说的:

我在这个短语处出错:

Bundle args = new Bundle();
args.putLong("id", ...);           //Some arbitrary value
showDialog(DELETE_DIALOG, args);

我有一个onPrepareDialog 方法:

@Override
protected void onPrepareDialog(int id, Dialog dialog, Bundle args) {
    switch (id) {
    case DELETE_DIALOG:
        AlertDialog log = (AlertDialog) dialog;
        final Bundle bundle = args;
        log.setButton(DialogInterface.BUTTON_POSITIVE, "Ok", new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog, int which) {
                long id = bundle.getLong("id");

                getContentResolver().delete(Tasks.CONTENT_URI, Tasks._ID + "=" + id, null);
                adapter.notifyDataSetChanged();
            }
        });
        break;
    default:
        break;
    }
}

可能是什么问题？

通常这意味着您编译的类和您运行的类是不同的版本。您正在调用的方法可由您的编译器访问，但在运行时不可用于 JVM。
