皆さん、こんにちは。webview の html 埋め込みビデオで全画面表示サポートを有効にする方法について質問を受けました。マニフェストでハードウェア アクセラレーションが true で、ビデオは正常に動作しますが、全画面表示にするとビデオが停止します。

ここに私のコードがあります

import com.photoshop.video.tutorials.R;
import android.annotation.SuppressLint;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.text.TextUtils;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.ProgressBar;

public class WebViewFragment extends Fragment {
public final static String TAG = WebViewFragment.class.getSimpleName();

private WebView viewContentWebView;
private String url;

private boolean resetHistory = true;

@SuppressLint("SetJavaScriptEnabled")
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
final View v = inflater.inflate(R.layout.webview, container, false);

final ProgressBar viewContentProgress = (ProgressBar) v.findViewById(R.id.progress);
viewContentWebView = (WebView) v.findViewById(R.id.webview);
viewContentWebView.getSettings().setJavaScriptEnabled(true);
viewContentWebView.setWebViewClient(new WebViewClient() {

    public void onReceivedError(WebView view, int errorCode, String description,          String failingUrl) {
        viewContentWebView.loadUrl("file:///android_asset/myerrorpage.html");

    }



@Override
  public boolean shouldOverrideUrlLoading(WebView view, String url) {
    return super.shouldOverrideUrlLoading(view, url);
  }
});
viewContentWebView.setWebChromeClient(new WebChromeClient() {
  @Override
  public void onProgressChanged(WebView view, int newProgress) {
    viewContentProgress.setProgress(newProgress);
    viewContentProgress.setVisibility(newProgress == 100 ? View.GONE : View.VISIBLE);

    if (newProgress == 100 && resetHistory) {
        viewContentWebView.clearHistory();
        resetHistory = false;
    }
  }
});
return v;
}

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
reload();
}

@Override
public void onHiddenChanged(boolean hidden) {
super.onHiddenChanged(hidden);
if (hidden)
  viewContentWebView.stopLoading();
else
  reload();
}

public void setUrl(String url) {
this.url = url;

if (viewContentWebView != null)
  viewContentWebView.stopLoading();

resetHistory = true;
}

public void reload() {
if (TextUtils.isEmpty(url))
  return;

viewContentWebView.loadUrl(url);
}

public boolean onBackPressed() {
if (viewContentWebView.canGoBack()) {
  viewContentWebView.goBack();
  return true;
}
return false;
}
}

私はAndroidに非常に慣れていないので、どうすればこれほど多くの感謝と少しの忍耐を得ることができますか

WebChromeClient で次の 2 つのメソッドをオーバーライドする必要があります。

  • public void onShowCustomView(View ビュー、CustomViewCallback コールバック);

  • public void onHideCustomView();

これは私が使用しているコードの抜粋です: 

private View mCustomView;

private class MyWebChromeClient extends WebChromeClient {
        private int mOriginalOrientation;
        private FullscreenHolder mFullscreenContainer;
        private CustomViewCallback mCustomViewCollback;

        @Override
        public void onShowCustomView(View view, CustomViewCallback callback) {

            if (mCustomView != null) {
                callback.onCustomViewHidden();
                return;
            }

            mOriginalOrientation = mActivity.getRequestedOrientation();

            FrameLayout decor = (FrameLayout) mActivity.getWindow().getDecorView();

            mFullscreenContainer = new FullscreenHolder(mActivity);
            mFullscreenContainer.addView(view, ViewGroup.LayoutParams.MATCH_PARENT);
            decor.addView(mFullscreenContainer, ViewGroup.LayoutParams.MATCH_PARENT);
            mCustomView = view;
            mCustomViewCollback = callback;
            mActivity.setRequestedOrientation(mOriginalOrientation);

        }

        @Override
        public void onHideCustomView() {
            if (mCustomView == null) {
                return;
            }

            FrameLayout decor = (FrameLayout) mActivity.getWindow().getDecorView();
            decor.removeView(mFullscreenContainer);
            mFullscreenContainer = null;
            mCustomView = null;
            mCustomViewCollback.onCustomViewHidden();
            // show the content view.

            mActivity.setRequestedOrientation(mOriginalOrientation);
        }


    static class FullscreenHolder extends FrameLayout {

        public FullscreenHolder(Context ctx) {
            super(ctx);
            setBackgroundColor(ctx.getResources().getColor(android.R.color.black));
        }

        @Override
        public boolean onTouchEvent(MotionEvent evt) {
            return true;
        }
    }
