activity继承Cocos2dxActivity后无法监听安卓返回按键

前提：

    public class TestActivity  extends Cocos2dxActivity {
        @Override
        public boolean onKeyDown( int keyCode, KeyEvent event) {// 监听不到

原因：

Called when a key was pressed down and not handled by any of the views inside of the activity. So, for example, key presses while the cursor is inside a TextView will not trigger the event (unless it is a navigation to another object) because TextView handles its own key presses. If the focused view didn't want this event, this method is called.

处理：

    修改 org.cocos2dx.lib. Cocos2dxGLSurfaceView

        原：

     @Override
     public boolean onKeyDown (final int pKeyCode, final KeyEvent pKeyEvent) {
            switch (pKeyCode) {
                 case KeyEvent. KEYCODE_BACK:
                 case KeyEvent. KEYCODE_MENU:
                      this.queueEvent( new Runnable() {
                            @Override
                            public void run() {
                                Cocos2dxGLSurfaceView.this.
                                   mCocos2dxRenderer.handleKeyDown(pKeyCode);
                           }
                     });
                      return true;
                 default:
                      return super.onKeyDown(pKeyCode, pKeyEvent);
           }
     }

     改：

     @Override
     public boolean onKeyDown( final int pKeyCode, final KeyEvent pKeyEvent) {
            switch (pKeyCode) {
                 case KeyEvent. KEYCODE_BACK:
                      return false;
                 case KeyEvent. KEYCODE_MENU:
                      this.queueEvent( new Runnable() {
                            @Override
                            public void run() {
                                Cocos2dxGLSurfaceView.this.
                                   mCocos2dxRenderer.handleKeyDown(pKeyCode);
                           }
                     });
                      return true;
                 default:
                      return super.onKeyDown(pKeyCode, pKeyEvent);
           }
     }

经测试 可正常监听返回按键
