XWalkView

java.lang.Object

- - android.view.ViewGroup
  - - android.widget.FrameLayout
    - - org.xwalk.core.XWalkView

All Implemented Interfaces:

```
public class XWalkView
extends android.widget.FrameLayout
```
XWalkView represents an Android view for web apps/pages. Thus most of attributes for Android view are valid for this class. Since it internally uses android.view.SurfaceView for rendering web pages by default, it can't be resized, rotated, transformed and animated due to the limitations of SurfaceView. Alternatively, if the preference key XWalkPreferences.ANIMATABLE_XWALK_VIEW is set to True, XWalkView can be transformed and animated because TextureView is intentionally used to render web pages for animation support. Besides, XWalkView won't be rendered if it's invisible.

In embedded mode, the developer can use XWalkView in onCreate() directly. But in shared mode and lite mode, the Crosswalk runtime isn't loaded yet at the moment the activity is created, so the embedding API won't be usable immediately. To make your code compatible with all modes, please refer to the examples in XWalkActivity or XWalkInitializer.

XWalkView needs hardware acceleration to render web pages. As a result, the AndroidManifest.xml of the caller's app must be appended with the attribute "android:hardwareAccelerated" and its value must be set as "true".
```
 <application android:name="android.app.Application" android:label="XWalkUsers"
     android:hardwareAccelerated="true">
 
```
Crosswalk provides 2 major callback classes, namely XWalkResourceClient and XWalkUIClient for listening to the events related to resource loading and UI. By default, Crosswalk has a default implementation. Callers can override them if needed.

Unlike other Android views, this class has to listen to system events like intents and activity result. The web engine inside this view need to get and handle them. With contianer activity's lifecycle change, XWalkView will pause all timers and other components like videos when activity paused, resume back them when activity resumed. When activity is about to destroy, XWalkView will destroy itself as well. Embedders can also call onHide() and pauseTimers() to explicitly pause XWalkView. Similarily with onShow(), resumeTimers() and onDestroy(). For example:
```
   import android.app.Activity;
   import android.os.Bundle;

   import org.xwalk.core.internal.XWalkResourceClient;
   import org.xwalk.core.internal.XWalkUIClient;
   import org.xwalk.core.internal.XWalkView;

   public class MyActivity extends Activity {
       XWalkView mXwalkView;

       class MyResourceClient extends XWalkResourceClient {
           MyResourceClient(XWalkView view) {
               super(view);
           }

           @Override
           WebResourceResponse shouldInterceptLoadRequest(XWalkView view, String url) {
               // Handle it here.
               ...
           }
       }

       class MyUIClient extends XWalkUIClient {
           MyUIClient(XWalkView view) {
               super(view);
           }

           @Override
           void onFullscreenToggled(XWalkView view, String url) {
               // Handle it here.
               ...
           }
       }

       @Override
       protected void onCreate(Bundle savedInstanceState) {
           mXwalkView = new XWalkView(this);
           setContentView(mXwalkView);
           mXwalkView.setResourceClient(new MyResourceClient(mXwalkView));
           mXwalkView.setUIClient(new MyUIClient(mXwalkView));
           mXwalkView.load("http://www.crosswalk-project.org", null);
       }

       @Override
       protected void onActivityResult(int requestCode, int resultCode, Intent data) {
           if (mXwalkView != null) {
               mXwalkView.onActivityResult(requestCode, resultCode, data);
           }
       }

       @Override
       protected void onNewIntent(Intent intent) {
           if (mXwalkView != null) {
               mXwalkView.onNewIntent(intent);
           }
       }
   }
