Wikitude

Hello. 

I am using the example Android App (NativeSDKExamples): in particolar the class SimpleClientTrackingActivity.java, because I need to use a Marker Recognition.

I have a question:

In this Activity appears the camera on all the display. 

Can I add simple buttons on the display layout (over the camera display) and How can I modify the layout (to add View) ?

This is the onCreate() method of the Activity class:

-------------------------------------------------

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    mWikitudeSDK = new WikitudeSDK(this);
    NativeStartupConfiguration startupConfiguration = new NativeStartupConfiguration();
    startupConfiguration.setLicenseKey(WikitudeSDKConstants.WIKITUDE_SDK_KEY);
    startupConfiguration.setCameraPosition(CameraSettings.CameraPosition.BACK);
    startupConfiguration.setCameraResolution(CameraSettings.CameraResolution.AUTO);

    mWikitudeSDK.onCreate(getApplicationContext(), this, startupConfiguration);

    mTargetCollectionResource = mWikitudeSDK.getTrackerManager().createTargetCollectionResource("file:///android_asset/tracker.wtc", new TargetCollectionResourceLoadingCallback() {
                @Override
                public void onError(int errorCode, String errorMessage) {
                    Log.v(TAG, "Failed to load target collection resource. Reason: " + errorMessage);
                }

                @Override
                public void onFinish() {
                    mWikitudeSDK.getTrackerManager().createImageTracker(mTargetCollectionResource, SimpleClientTrackingActivity.this, null);
                }
            });

    mDropDownAlert = new DropDownAlert(this);
    mDropDownAlert.setText("Scan Target #1 (surfer):");
    mDropDownAlert.addImages("surfer.png");
    mDropDownAlert.setTextWeight(0.5f);
    mDropDownAlert.show();
}

-------------------------------------------------

Thank you very much!

Best Regards!

To take a picture with the camera, what is the method to call?
