由于提供的答案与实际问题完全无关,因此这里是实际答案:

  1. 您只需将文本实体附加到显示圆圈的精灵即可。

  2. 或者看看BitmapTextureAtlasSourceDecorators: https://github.com/nicolasgramlich/AndEngine/tree/GLES2/src/org/andengine/opengl/texture/atlas/bitmap/source/decorator

  3. 关于从实体创建主体,请看这里: https://github.com/nicolasgramlich/AndEngineExamples/blob/GLES2/src/org/andengine/examples/PhysicsExample.java#L179

试试这个解决方案:

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(demoview);
    }

    private class DemoView extends View{
        public DemoView(Context context){
            super(context);
        }

        @Override
        protected void onDraw(Canvas canvas) {
            super.onDraw(canvas);
            Paint p = new Paint();
            p.setColor(Color.RED);
            DashPathEffect dashPath = new DashPathEffect(new float[]{5,5}, (float)1.0);

            p.setPathEffect(dashPath);
            p.setStyle(Style.STROKE);
            canvas.drawCircle(100, 100, 50, p);
            Paint pp = new Paint();
            pp.setColor(Color.BLUE);
            canvas.drawText("kadir", 100, 100, pp);    
            invalidate();
        }
    }
}
