Question

我有一个简单的Android应用程序，它只是运行Web应用程序的WebView。

如果我正在使用输入并在最后一个可见输入上按Enter键，键盘就会消失（这很好），但我失去了与WebView中运行的Web应用程序进行交互的所有能力。我仍然可以看到应用程序运行。按后退键而不是输入会导致键盘消失，我没有问题。

任何想法发生了什么以及如何让它停止？

我尝试拦截焦点更改并请求关注Web视图，但似乎Web视图本身永远不会失去焦点。我也尝试过设置一个间隔来重新聚焦web apps document.body，但它没有效果。

代码：

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#000000"
    tools:context="com.particlesandbox.Play">

    <WebView
        android:id="@+id/view"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</FrameLayout>


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_play);

    mWebView = (WebView) findViewById(R.id.view);
    mWebView.getSettings().setJavaScriptEnabled(true);
    mWebView.getSettings().setUseWideViewPort(true);
    mWebView.requestFocus(View.FOCUS_DOWN);
    mWebView.loadUrl("file:///android_asset/www/index.html");

}

Answer 1

这是Pixi.js中的AccessibilityManager。

如评论所述，它在所有内容之前创建了div。

我在renderer上将其销毁，问题就消失了。

renderer.plugins.accessibility.destroy()

使用最后一个可见输入按Enter后，Android WebView无响应
