在简单活动中调用AndEngine视图

标签： android andengine

我有和发动机表面视图及其重复编码活动。现在我想在简单的活动中调用这个andengine View，我不想通过意图调用和引擎活动。就像Custome View

一样 
**XML View:**

<?xml version="1.0" encoding="UTF-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>

<TextView
android:id="@+id/btn_get_involved"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="@string/tv_xmllayoutexample_above"
android:textSize="20sp" />

<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="#FFF"
android:orientation="horizontal"
android:padding="2px" >

<org.andengine.opengl.view.RenderSurfaceView
android:id="@+id/xmllayoutexample_rendersurfaceview"
android:layout_width="240px"
android:layout_height="240px"
android:layout_margin="10px" />
</LinearLayout>

<TextView
android:id="@+id/btn_get_involved"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="@string/tv_xmllayoutexample_below"
android:textSize="20sp" />
</LinearLayout>

</ScrollView>


**AndEngine Activity:**


public class XMLLayoutExample extends SimpleLayoutGameActivity {


private static final int CAMERA_WIDTH = 720;
private static final int CAMERA_HEIGHT = 480;



private BitmapTextureAtlas mBitmapTextureAtlas;
private ITextureRegion mParticleTextureRegion;



@Override
protected int getLayoutID() {
return R.layout.xmllayoutexample;
}

@Override
protected void onSetContentView() {

}

@Override
protected int getRenderSurfaceViewID() {
return R.id.xmllayoutexample_rendersurfaceview;
}

@Override
public EngineOptions onCreateEngineOptions() {
Toast.makeText(this, "Touch the screen to move the particlesystem.", Toast.LENGTH_LONG).show();

final Camera camera = new Camera(0, 0, XMLLayoutExample.CAMERA_WIDTH, XMLLayoutExample.CAMERA_HEIGHT);

return new EngineOptions(true, ScreenOrientation.LANDSCAPE_FIXED, new RatioResolutionPolicy(XMLLayoutExample.CAMERA_WIDTH, XMLLayoutExample.CAMERA_HEIGHT), camera);
}

@Override
protected void onCreateResources() {
BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/");

this.mBitmapTextureAtlas = new BitmapTextureAtlas(this.getTextureManager(), 32, 32, TextureOptions.BILINEAR);

this.mParticleTextureRegion = BitmapTextureAtlasTextureRegionFactory.createFromAsset(this.mBitmapTextureAtlas, this, "particle_point.png", 0, 0);

this.mBitmapTextureAtlas.load();
}

@Override
protected Scene onCreateScene() {
this.mEngine.registerUpdateHandler(new FPSLogger());

final Scene scene = new Scene();

final CircleOutlineParticleEmitter particleEmitter = new CircleOutlineParticleEmitter(XMLLayoutExample.CAMERA_WIDTH * 0.5f, (XMLLayoutExample.CAMERA_HEIGHT * 0.5f) + 20, 80);
final SpriteParticleSystem particleSystem = new SpriteParticleSystem(particleEmitter, 60, 60, 360, this.mParticleTextureRegion, this.getVertexBufferObjectManager());

scene.setOnSceneTouchListener(new IOnSceneTouchListener() {
@Override
public boolean onSceneTouchEvent(final Scene pScene, final TouchEvent pSceneTouchEvent) {
particleEmitter.setCenter(pSceneTouchEvent.getX(), pSceneTouchEvent.getY());
return true;
}
});

particleSystem.addParticleInitializer(new ColorParticleInitializer<Sprite>(1, 0, 0));
particleSystem.addParticleInitializer(new AlphaParticleInitializer<Sprite>(0));
particleSystem.addParticleInitializer(new BlendFunctionParticleInitializer<Sprite>(GLES20.GL_SRC_ALPHA, GLES20.GL_ONE));
particleSystem.addParticleInitializer(new VelocityParticleInitializer<Sprite>(-2, 2, -20, -10));
particleSystem.addParticleInitializer(new RotationParticleInitializer<Sprite>(0.0f, 360.0f));
particleSystem.addParticleInitializer(new ExpireParticleInitializer<Sprite>(6));

particleSystem.addParticleModifier(new ScaleParticleModifier<Sprite>(0, 5, 1.0f, 2.0f));
particleSystem.addParticleModifier(new ColorParticleModifier<Sprite>(0, 3, 1, 1, 0, 0.5f, 0, 0));
particleSystem.addParticleModifier(new ColorParticleModifier<Sprite>(4, 6, 1, 1, 0.5f, 1, 0, 1));
particleSystem.addParticleModifier(new AlphaParticleModifier<Sprite>(0, 1, 0, 1));
particleSystem.addParticleModifier(new AlphaParticleModifier<Sprite>(5, 6, 1, 0));

scene.attachChild(particleSystem);

return scene;
}


}


**MySimple Activity:(Main Launcher Activity)**



public class TestActivity extends Activity {
/** Called when the activity is first created. */
Button b;
ImageView iv;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.xmlLayout);

}
}

LogCat查看：

我正在尝试这个但却给出错误：

答案 0 :(得分：1)

不要扩展SimpleBaseGameActivity。使用LayoutGameActivity类进行扩展。 实施以下方法：

@Override
protected int getLayoutID() 
{
    return R.layout.my_layout;
}

@Override
protected int getRenderSurfaceViewID() 
{
    return R.id.xml_rendersurfaceview;
}

my_layout内容：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

    <org.anddev.andengine.opengl.view.RenderSurfaceView
    android:id="@+id/xml_rendersurfaceview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"/>

    <RelativeLayout 
    android:layout_width="fill_parent"
    android:layout_height="50dip"
    android:layout_alignParentTop="true">


    </RelativeLayout>

</RelativeLayout>

并在此布局中添加布局内容。
