Android：webView加载h5网页视频，播放不了，以及横屏全屏的问题和实现自定义加载进度条的效果

1、webView加载h5网页视频，播放不了，android3.0之后要在menifest添加硬件加速的属性 android:hardwareAccelerated="true"。

2、接着是视屏播放实现横屏全屏效果，以及自定义加载提示和播放进度条。

public class myWebChromeClient extends WebChromeClient {

        @Override

        public void onReceivedTitle(WebView view, String title) {

            super.onReceivedTitle(view, title);

            LogUtils.i(NewsDetailsActivity.class, "title:" + title);

            if (getIntent().getStringExtra("ifIsFromFocus") != null) {

                if (ifFirstWebPage == 0) {

                    ifFirstWebPage++;

                    pre_title = title;

                }

                shareTitle = title;

                tvTitle.setText(title);

            }

        }

        private View xprogressvideo;

        // 播放网络视频时全屏会被调用的方法

        @Override

        public void onShowCustomView(View view, CustomViewCallback callback) {

            rlTopTitle = (RelativeLayout) findViewById(R.id.rlTopTitle);

            rlTopTitle.setVisibility(View.GONE);

            getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

            mWebView.setVisibility(View.INVISIBLE);

            // 如果一个视图已经存在，那么立刻终止并新建一个

            if (xCustomView != null) {

                callback.onCustomViewHidden();

                return;

            }

            video_fullView.addView(view);

            xCustomView = view;

            xCustomViewCallback = callback;

            video_fullView.setVisibility(View.VISIBLE);

        }

        // 视频播放退出全屏会被调用的

        @Override

        public void onHideCustomView() {

            if (xCustomView == null)// 不是全屏播放状态

                return;

            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

            xCustomView.setVisibility(View.GONE);

            video_fullView.removeView(xCustomView);

            xCustomView = null;

            video_fullView.setVisibility(View.GONE);

            xCustomViewCallback.onCustomViewHidden();

            mWebView.setVisibility(View.VISIBLE);

            rlTopTitle = (RelativeLayout) findViewById(R.id.rlTopTitle);

            rlTopTitle.setVisibility(View.VISIBLE);

            getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

            mWebView.getSettings().setBuiltInZoomControls(true);

        }

        // 视频加载时进程loading

        @Override

        public View getVideoLoadingProgressView() {

            if (xprogressvideo == null) {

                LayoutInflater inflater = LayoutInflater

                        .from(NewsDetailsActivity.this);

                xprogressvideo = inflater.inflate(

                        R.layout.video_loading_progress, null);

            }

            return xprogressvideo;

        }

    }

xwebchromeclient = new myWebChromeClient();

            mWebView.setWebChromeClient(xwebchromeclient);

进度加载提示和播放进度条的布局文件如下：

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

 android:id="@+id/progress_indicator"

 android:layout_width="wrap_content"

 android:layout_height="wrap_content"

 android:layout_centerInParent="true"

 android:orientation="vertical" >

 <ProgressBar

 android:id="@android:id/progress"

 style="?android:attr/progressBarStyleLarge"

 android:layout_width="wrap_content"

 android:layout_height="wrap_content"

 android:layout_gravity="center" />

 <TextView

 android:layout_width="wrap_content"

 android:layout_height="wrap_content"

 android:layout_gravity="center"

 android:paddingTop="5dip"

 android:text="正在玩命加载视频中。。。"

android:textColor="?android:attr/textColorPrimary"

 android:textSize="14sp" />

</LinearLayout>
