Android 日常开发(32) WebView视频全屏播放

前言

之前也做过了，很多遍全屏的控制，但是一直都没有写成笔记去总结。

webview setting

 		this.getSettings().setJavaScriptEnabled(true);
        this.getSettings().setRenderPriority(WebSettings.RenderPriority.HIGH);
        this.getSettings().setDomStorageEnabled(true);//开启 DOM storage API 功能
        this.getSettings().setDatabaseEnabled(true);//开启 database storage API 功能
        this.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT);//设置缓存
        String cacheDirPath = getContext().getFilesDir().getAbsolutePath() + APP_CACAHE_DIRNAME;
        this.getSettings().setAppCacheEnabled(true);

        //设置  Application Caches 缓存目录
        this.getSettings().setAppCachePath(cacheDirPath);

        this.getSettings().setUseWideViewPort(true);
        this.getSettings().setDisplayZoomControls(true);

        //设置全屏播放
        this.getSettings().setLoadWithOverviewMode(true);
        this.getSettings().setAllowFileAccess(true);
        this.getSettings().setSupportZoom(true);
        this.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
        this.getSettings().setPluginState(WebSettings.PluginState.ON);

WebChromeClient重写onShowCustomView和onHideCustomView方法

 View myVideoView;
            View myNormalView;
            CustomViewCallback callback;

            @Override
            public void onShowCustomView(View view, CustomViewCallback callback) {
                fullScreen();
                //将videoview 添加到framelayout
                ViewGroup viewGroup = (ViewGroup) flVideoContent.getParent();
                viewGroup.removeView(flVideoContent);
                viewGroup.addView(view);
                myVideoView = view;
                myNormalView = flVideoContent;
                this.callback = callback;
                super.onShowCustomView(view, callback);
            }

            @Override
            public void onHideCustomView() {
                fullScreen();
                //将videoview 移出 framelayout
                if (callback != null) {
                    callback.onCustomViewHidden();
                    callback = null;
                }
                if (myVideoView != null) {
                    ViewGroup viewGroup = (ViewGroup) myVideoView.getParent();
                    viewGroup.removeView(myVideoView);
                    viewGroup.addView(myNormalView);
                }
                super.onHideCustomView();
            }

重写onConfigurationChanged方法

重写此方法用于解决屏幕反转问题

 @Override
    public void onConfigurationChanged(Configuration config) {
        super.onConfigurationChanged(config);
        switch (config.orientation) {
            case Configuration.ORIENTATION_LANDSCAPE://横屏
                //清空非全屏
                getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
                //设置全屏
                getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
                break;
            case Configuration.ORIENTATION_PORTRAIT://竖屏
                //清空全屏
                getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
                //设置不全屏
                getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
                break;
        }
    }

  /**
     * 切换屏幕，使得屏幕旋转
     */
    private void fullScreen() {
        if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
            jyTitleBar.setVisibility(View.GONE);
            Log.i("xxx","横屏");
        } else {
            //解决标题影响绘制问题
            jyTitleBar.setVisibility(View.VISIBLE);
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
            Log.i("xxx","竖屏");
        }
    }

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">


    <TitleBar
        android:id="@+id/jyTitleBar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:jy_right_text="保存"
        app:jy_show_right_image="false"
        app:jy_left_image="@drawable/ic_btn_return" />


    <JYWebView
        android:id="@+id/webView"
        android:layout_below="@id/jyTitleBar"
        style="@style/scrollview_style"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <FrameLayout
        android:id="@+id/fl_video_content"
        android:background="@color/c_F5F6FA"
        android:visibility="gone"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</RelativeLayout>

每天记一记，总会再用到的
