我创建了一个网页，其中放置了一个text field并将该文本字段用作自动完成。当autocomplete出现时，此focus()加载数据并键入任何值。它可以正常工作并显示autocomplete。
当我在Android Web视图中运行此页面时，出现了一些问题。当focus上的text field（在WebView中）并键入value时，它不会加载自动完成值。当我在文本字段click的外部focus再次在文本字段WebView时，它将加载自动完成值。
谁能告诉我autocomplete在第一个focus之后加载的focus所需的哪些设置，而无需定义第二个public class ShowDetailsActivity extends AppCompatActivity {
