The following code is needed to show the video player that is started by the web core framework. The key to the entire flow is that the VideoView is passed back to the WebChromeClient and you need to attach that view to your view hierarchy.
I have assembled it through reviewing the Browser source code available as part of the AOSP.
This code references 4 Views which may not be obvious. The view hierarchy is:
FrameLayout mContentView (root)WebView mWebView (child of mContentView)FrameLAyout mCustomViewContainer (child of mContentView)View mCustomView (child of mCustomViewContainer)
The views are configured as part of setting up the container activity.
<FrameLayout
android:id="@+id/fullscreen_custom_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FF000000"/>
<FrameLayout
android:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" >
<WebView
android:id="@+id/webView"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</FrameLayout>
</FrameLayout>
In your Activities onCreate:
mContentView = (FrameLayout) findViewById(R.id.main_content);
mWebView = (WebView) findViewById(R.id.webView);
mCustomViewContainer = (FrameLayout) findViewById(R.id.fullscreen_custom_content);
Register a WebChromeClient with mWebView. That client should override the following 2 - 4 methods:
void onShowCustomView(View view, WebChromeClient.CustomViewCallback callback)
{
// if a view already exists then immediately terminate the new one
if (mCustomView != null)
{
callback.onCustomViewHidden();
return;
}
// Add the custom view to its container.
mCustomViewContainer.addView(view, COVER_SCREEN_GRAVITY_CENTER);
mCustomView = view;
mCustomViewCallback = callback;
// hide main browser view
mContentView.setVisibility(View.GONE);
// Finally show the custom view container.
mCustomViewContainer.setVisibility(View.VISIBLE);
mCustomViewContainer.bringToFront();
}
void onHideCustomView()
{
if (mCustomView == null)
return;
// Hide the custom view.
mCustomView.setVisibility(View.GONE);
// Remove the custom view from its container.
mCustomViewContainer.removeView(mCustomView);
mCustomView = null;
mCustomViewContainer.setVisibility(View.GONE);
mCustomViewCallback.onCustomViewHidden();
// Show the content view.
mContentView.setVisibility(View.VISIBLE);
}
public Bitmap getDefaultVideoPoster()
{
if (mDefaultVideoPoster == null)
{
mDefaultVideoPoster = BitmapFactory.decodeResource(getResources(), R.drawable.default_video_poster);
}
return mDefaultVideoPoster;
}
public View getVideoLoadingProgressView()
{
if (mVideoProgressView == null)
{
LayoutInflater inflater = LayoutInflater.from(this);
mVideoProgressView = inflater.inflate(R.layout.video_loading_progress, null);
}
return mVideoProgressView;
}
You may also want to add activity life-cycle bindings like:
@Override
protected void onStop()
{
super.onStop();
if (mCustomView != null)
{
if (mCustomViewCallback != null)
mCustomViewCallback.onCustomViewHidden();
mCustomView = null;
}
}
@Override
public void onBackPressed()
{
if (mCustomView != null)
{
onHideCustomView();
} else
{
finish();
}
}
To your activity to make the video hide when the activity is stopped or the back button is pressed.
