How to add libgdx as a sub view in android

Question

I have main.xml as follows:

  <RelativeLayout>
     ...
     <FrameLayout
                    android:id="@+id/panel_sheet"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent">

        <com.libgdx.Sheet3DViewGdx 
                android:id="@+id/m3D"
                android:layout_width="1000dp"
                android:layout_height="600dp"
        />

    </FrameLayout>

...
</RelativeLayout>

And my main activity class is as follows:

public class Test extends Activity {

    MainActivity  m3DActivity;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
}

My GDX class is as follows which extend ApplicationListener class rather than View.

public class Sheet3DViewGdx implements ApplicationListener{

    @Override
    public void create() {
        InputStream in = Gdx.files.internal("data/obj/Human3DModel.obj").read();
        model =  ObjLoader.loadObj(in);
    }

    @Override
    public void dispose() {
    }

    @Override
    public void pause() {
    }


    @Override
    public void render() {
        Gdx.gl.glClearColor(0.0f, 0.0f, 0.0f, 1.0f);
        Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT);
        model.render(GL10.GL_TRIANGLES);
    }

    @Override
    public void resize(int arg0, int arg1) {
        float aspectRatio = (float) arg0 / (float) arg1;
    }

    @Override
    public void resume() {
    }
}

Now, how should I add Sheet3DViewGdx as a subview in my main layout?

Answer 1

The AndroidApplication class (which extends activity) has a method named initializeForView(ApplicationListener, AndroidApplicationConfiguration) that will return a View you can add to your layout.

So your Test-class can extend AndroidApplication instead of Activity so that you can call that method and add the View to your layout.

If that's not an option, for some reason, take a look at what AndroidApplication source code does, and mimic that.
