Android 如何制作全屏视频？

Question

当我在 WebView 中制作视频全屏时，工具栏没有隐藏。我该如何隐藏它？下面你可以看到我使用的代码。我正在使用片段和导航抽屉菜单。

我建议您尝试以下代码并删除与加载 WebView 内容相关的侦听器。

你需要先实现在你的webview中加载网站的方法。

private void loadWebsite() {
    ConnectivityManager connectivityManager = (ConnectivityManager) getApplication().getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo networkInfo = connectivityManager .getActiveNetworkInfo();
    if (networkInfo != null && networkInfo.isConnectedOrConnecting()) {
        mWebView.loadUrl("yourURL");
    } else {
        mWebView.setVisibility(View.GONE);
    }
}

从这里开始，您需要实现 2 个不同的类“Browser_Home”和“MyChrome”。出于测试目的，只需将其编写在 searchWebFragment 之外，稍后您可以将其实现为单独的 java 文件。只有 Browser_Home 类，全屏按钮将被禁用。添加 MyChrome 类后，将启用全屏按钮，并且工具栏应按预期消失。

class Browser_home extends WebViewClient {

    Browser_home() {
    }

    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) {
        super.onPageStarted(view, url, favicon);

    }

    @Override
    public void onPageFinished(WebView view, String url) {
        setTitle(view.getTitle());
        progressBar.setVisibility(View.GONE);
        super.onPageFinished(view, url);

    }
}

private class MyChrome extends WebChromeClient {

    private View mCustomView;
    private WebChromeClient.CustomViewCallback mCustomViewCallback;
    protected FrameLayout mFullscreenContainer;
    private int mOriginalOrientation;
    private int mOriginalSystemUiVisibility;

    MyChrome() {}

    public Bitmap getDefaultVideoPoster()
    {
        if (mCustomView == null) {
            return null;
        }
        return BitmapFactory.decodeResource(getApplicationContext().getResources(), 2130837573);
    }

    public void onHideCustomView()
    {
        ((FrameLayout)getWindow().getDecorView()).removeView(this.mCustomView);
        this.mCustomView = null;
        getWindow().getDecorView().setSystemUiVisibility(this.mOriginalSystemUiVisibility);
        setRequestedOrientation(this.mOriginalOrientation);
        this.mCustomViewCallback.onCustomViewHidden();
        this.mCustomViewCallback = null;
    }

    public void onShowCustomView(View paramView, WebChromeClient.CustomViewCallback paramCustomViewCallback)
    {
        if (this.mCustomView != null)
        {
            onHideCustomView();
            return;
        }
        this.mCustomView = paramView;
        this.mOriginalSystemUiVisibility = getWindow().getDecorView().getSystemUiVisibility();
        this.mOriginalOrientation = getRequestedOrientation();
        this.mCustomViewCallback = paramCustomViewCallback;
        ((FrameLayout)getWindow().getDecorView()).addView(this.mCustomView, new FrameLayout.LayoutParams(-1, -1));
        getWindow().getDecorView().setSystemUiVisibility(3846);
    }
}

最后，将以下函数和属性应用到您的 webview 并再试一次。请记住在您的 OnCreate 方法中应用这些：

        mWebView.setWebViewClient(new Browser_home());
    WebSettings webSettings = mWebView.getSettings();
    webSettings.setJavaScriptEnabled(true);
    webSettings.setAllowFileAccess(true);
    webSettings.setAppCacheEnabled(true);
    loadWebsite();

让我知道这是否可行，我可以将代码和课程的帮助归功于相应的人。

创建一个文件夹row并将视频复制到资源上的原始文件夹并执行以下步骤，

在您的 XML 文件中添加 VideoView，

   <VideoView
    android:id="@+id/vdoPlayer"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_alignParentTop="true"
    android:layout_alignParentLeft="true"
    android:layout_alignParentRight="true"
    android:layout_alignParentBottom="true"/> 

在你的 .java 类文件上做，

 Uri uri = Uri.parse("android.resource://Your package name Here/" + R.raw.welcome_video);
 vdoPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
     @Override
     public void onPrepared(MediaPlayer mp) {
         mp.setLooping(true);
     }
 });
 vdoPlayer.setVideoURI(uri);
 vdoPlayer.start();
