Hello Everyone, actually i'm having a big problem while programming an augmented reality app where i need to overlap a cameraview and a glsurfaceview. Im trying to fix this for several days, but i cant get it solved. So here's my problem: I have an Activity "FView" where i currently Create 1 GLView (extends GLSurfaceView and implements a Renderer) and a CameraView (extends Surfaceview and implements SurfaceHolder.Callback..). I add both of the Views by the following code in the onCreate of the FView: [HIGH] glsurfaceview = new GLView(this); camPrev = new CamView(this, (PreviewCallback) glsurfaceview); glsurfaceview.setEGLConfigChooser(8, 8, 8, 8, 16, 0); glsurfaceview.getHolder().setFormat(PixelFormat.TRANSLUCENT); glsurfaceview.setRenderer((GLView) glsurfaceview); setContentView(glsurfaceview); addContentView(camPrev, null); [/HIGH]This is the last "try". I already used a lot of other possibilities (e.g. different layouts..). What it does? When i start the Activity, holding my Smartphone in Landscape mode, i only see that the camera starts, no 3D-Objekts from my GLSurfaceView (the class itself works.. see following. But when i hold my Smartphone in Portrait mode, it works fine!. But i need it to work in both ways - Start Activity while holding it in both ways, but the Activity itself must be in landscape all the time. Im freaking out because i dont know how to solve it !. I hope you can help me. Thanks.
