在2dx下用到了android下的.9.png图片，下面是原图

 

查了一下2dx里有CCScale9Sprite，直接贴上背景图，毫无问题，

  1. CCSize bgRect = CCSizeMake(size.width,size.height/3);
  2. CCScale9Sprite *background   = CCScale9Sprite::create("dialog_bg.png");
  3. background->setContentSize(bgRect);
  4. background->setPosition(ccp(bgRect.width/2,-bgRect.height/2));
  5. this->addChild(background,5);
CCSize bgRect = CCSizeMake(size.width,size.height/3);

CCScale9Sprite *background   = CCScale9Sprite::create("dialog_bg.png");

background->setContentSize(bgRect);

background->setPosition(ccp(bgRect.width/2,-bgRect.height/2));

this->addChild(background,5);

然后按钮里也需要用到这个素材图，拉伸图片到我们需要的，用到了CCControlButton

  1. CCLabelTTF *title1 = CCLabelTTF::create("拍照", "Marker Felt", 30);
  2. CCControlButton* btn_takephoto = CCControlButton::create(title1,CCScale9Sprite::create("dialog_normal.png"));
  3. /* 设置按钮按下时的图片 */
  4. btn_takephoto->setBackgroundSpriteForState(CCScale9Sprite::create("dialog_pressed.png"), CCControlStateSelected);
  5. btn_takephoto->setPosition(ccp(bgRect.width/2,bgRect.height/5*4));
  6. btn_takephoto->setPreferredSize(btnRect);
  7. btn_takephoto->addTargetWithActionForControlEvents(this, cccontrol_selector(DialogPhoto::MenuItemCallback), CCControlEventTouchUpInside);
  8. background->addChild(btn_takephoto);
CCLabelTTF *title1 = CCLabelTTF::create("拍照", "Marker Felt", 30);

CCControlButton* btn_takephoto = CCControlButton::create(title1,CCScale9Sprite::create("dialog_normal.png"));

 /* 设置按钮按下时的图片 */

btn_takephoto->setBackgroundSpriteForState(CCScale9Sprite::create("dialog_pressed.png"), CCControlStateSelected);

btn_takephoto->setPosition(ccp(bgRect.width/2,bgRect.height/5*4));

btn_takephoto->setPreferredSize(btnRect);

btn_takephoto->addTargetWithActionForControlEvents(this, cccontrol_selector(DialogPhoto::MenuItemCallback), CCControlEventTouchUpInside);

background->addChild(btn_takephoto);

当然也可以用CCMenuItemSprite

  1. CCScale9Sprite* sp1 = CCScale9Sprite::create("dialog_normal.png");
  2. sp1->setContentSize(btnRect);
  3. CCScale9Sprite* sp2 = CCScale9Sprite::create("dialog_pressed.png");
  4. sp2->setContentSize(btnRect);
  5. CCMenuItemSprite* btn_takephoto = CCMenuItemSprite::create(sp1,sp2,this,menu_selector(DialogShare::MenuItemCallback));
  6. btn_takephoto->setPosition(ccp(bgRect.width/2,bgRect.height/5*4));
  7. btn_takephoto->setTag(DialogTakePhoto);
  8. CCLabelTTF* pLabel1 = CCLabelTTF::create("拍照", "Arial", 20);
  9. pLabel1->setColor(ccc3(0, 0, 0));
  10. pLabel1->setPosition(ccp(btnRect.width/2,btnRect.height/2));
  11. btn_takephoto->addChild(pLabel1);
CCScale9Sprite* sp1 = CCScale9Sprite::create("dialog_normal.png");

sp1->setContentSize(btnRect);

CCScale9Sprite* sp2 = CCScale9Sprite::create("dialog_pressed.png");

sp2->setContentSize(btnRect);

CCMenuItemSprite* btn_takephoto = CCMenuItemSprite::create(sp1,sp2,this,menu_selector(DialogShare::MenuItemCallback));

btn_takephoto->setPosition(ccp(bgRect.width/2,bgRect.height/5*4));

btn_takephoto->setTag(DialogTakePhoto);

CCLabelTTF* pLabel1 = CCLabelTTF::create("拍照", "Arial", 20);

pLabel1->setColor(ccc3(0, 0, 0));

pLabel1->setPosition(ccp(btnRect.width/2,btnRect.height/2));

btn_takephoto->addChild(pLabel1);
  1. <pre class="cpp" name="code">m_pMenu = CCMenu::create(btn_takephoto,btn_photoalbum,btn_cancel, NULL);
  2. m_pMenu->setPosition(CCPointZero);
  3. background->addChild(m_pMenu);</pre>
  1. m_pMenu = CCMenu::create(btn_takephoto,btn_photoalbum,btn_cancel, NULL);
  2. m_pMenu->setPosition(CCPointZero);
  3. background->addChild(m_pMenu);
m_pMenu = CCMenu::create(btn_takephoto,btn_photoalbum,btn_cancel, NULL);

m_pMenu->setPosition(CCPointZero);

background->addChild(m_pMenu);

下面就是我们所需的效果
