How to add libgdx as a sub view in android

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

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.
