Hi,
I'm new at this (java and opengl) so please bear with me if the
answer to the question is simple. :)
I'm trying to get a camera preview screen with the ability to
display 3d objects simultaneously. Having gone through the samples at
the api demos, I thought combining the
code for the the examples at
the api demo would suffice. But somehow its not working. The forces me
to shut down upon startup and the error is mentioned as null pointer
exception. Could someone share with me where did I go wrong and how to
proceed from there. How I did the combination for the
code is as shown
below:
myoverview.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<android.opengl.GLSurfaceView
android:id="@+id/cubes"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
<SurfaceView
android:id="@+id/camera"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</FrameLayout>
myoverview.java
import android.app.Activity;
import android.os.Bundle;
import android.view.SurfaceView;
import android.view.Window;
public class MyOverView extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Hide the window title.
requestWindowFeature(Window.FEATURE_NO_TITLE);
// camera view as the background
SurfaceView cameraView = (SurfaceView) findViewById(R.id.camera);
cameraView = new CameraView(this);
// visual of both cubes
GLSurfaceView cubesView = (GLSurfaceView) findViewById(R.id.cubes);
cubesView = new GLSurfaceView(this);
cubesView.setRenderer(new CubeRenderer(false));
// set view
setContentView(R.layout.myoverview);
}
}
GLSurfaceView.java
import android.content.Context;
class GLSurfaceView extends android.opengl.GLSurfaceView {
public GLSurfaceView(Context context) {
super(context);
}
}
NOTE :
I didnt list the rest of the files as they are just copies of
the api demos. The cameraView refers to the camerapreview.java example
and the CubeRenderer refers to the CubeRenderer.java and Cube.java
example. Any help would be appreciated as I've been stuck at this for a couple
of days :p Thanks
Sorry, didnt realise that the coding was out of place due to formatting mistakes. :p
