係『Android OpenGL ES』用『SurfaceView』蒞畀『OpenGL ES』渲染. 之前『SurfaceView』代碼擺係『MainActivity.java』.更佳方法係『SurfaceView』『Runnable』『SurfaceHolder.Callback』封裝成單獨『GameView calss』.以保持代碼『簡潔』同埋『重用』.
- 新建『java』
| 『File->New->Java Class』 |
- 封裝『Runnable』『Callback』
| public class GameView extends SurfaceView implements Runnable,SurfaceHolder.Callback{ |
- 『SurfaceView』變量
| int view_width,view_height;
public SurfaceHolder surfaceHolder; public Surface surface;//用蒞渲染 |
- 構造函數
| public GameView(Context context) {
super(context); init(context);// 設置渲染 } |
| public GameView(Context context, AttributeSet attrs) {
super(context); init(context);// 設置渲染 } |
| public GameView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context); init(context);// 設置渲染 } |
- 初此渲染设置
| public void init(Context context){
this.surfaceHolder = getHolder(); this.surfaceHolder.addCallback(this); this.surface = surfaceHolder.getSurface(); } |
- 創建表層,啟動渲染線程 run()
| @Override
public void surfaceCreated(SurfaceHolder surfaceHolder){ new Thread(this).start(); } |
- 表層改變, 當手機方向改變触發, 係游戲要禁止旋轉方向.
| @Override
public void surfaceChanged(SurfaceHolder surfaceHolder, int format, int width, int height){ view_width = width; view_height = height; } |
- 表層銷毀
| @Override
public void surfaceDestroyed(SurfaceHolder surfaceHolder) { } |
- 游戲運算渲染線程
| @Override
public void run() { AssetManager assetManager = getContext().getAssets(); Lib.init(assetManager, surface, view_width, view_height); while (true) {// 請求渲染 Lib.update(); } } |
