我正在尝试发送存储在Firebase中的文档的ID。文档的所有ID均打印在RecyclerView中，当您单击任何一个时，应将String中的ID发送到Fragment DatosEntregaActivity，以便它可以在“传递”的集合中搜索最后一个具有字段ID的文档活动的ID。 我已经用Bundle尝试过，但是单击时它不发送或不接收发送的数据。
这是当我单击RecyclerView的元素时抛出的错误

答案 0 :(得分：1)
要将Bundle传递给新的Activity，您需要设置intent的附加项，而不是Activity。在您的onClick中，您可以正确找到它的代码。
Intent intent = new Intent(ServicioActivity.this, DatosActivity.class);
Bundle bundle = new Bundle();
bundle.putString("documento", String.valueOf(clickedForm.getOrden_servicio()));
intent.putExtras(bundle);
startActivity(intent);
然后在您的Activity中。
@Override
public void onCreate(Bundle savedInstanceState) {
// ...
documento_os = getIntent().getExtras().getString("documento");
// ...
}
