Use a camera to take a photo

Add the surfaceview Control for displaying the landscape view in the main. xml layout file:

<Surfaceview Android: layout_width = "fill_parent" Android: layout_height = "240dip" Android: Id = "@ + ID/surfaceview"/>

Surfaceview = (surfaceview) This. findviewbyid (R. Id. surfaceview );

Surfaceview. getholder (). setfixedsize (176,144); // sets the resolution.

/* Set the surface below not to maintain its own buffer, but to wait for the screen rendering engine to push the content to the user */

Surfaceview. getholder (). settype (surfaceholder. surface_type_push_buffers );

Camera camera = camera. open ();

Windowmanager WM = (windowmanager) getsystemservice (context. window_service );

Display display = WM. getdefaultdisplay ();
