[Bada开发]基于bada1.0的5种控件介绍[待续]

以下的例子没有特殊说明则都是基于bada SDK 1.0.0

包括，图片加载、按钮、文字编辑区、确认框以及选框。

1.图片加载函数

Osp::Graphics::Bitmap*

BaseForm::GetBitmapN(const Osp::Base::String& name)

{

Bitmap* pBitmap = null;

Image* pImage = new Image();

String fullname(L"/Res/");

fullname.Append(name);

pImage->Construct();

if(fullname.EndsWith(L"jpg"))

{

pBitmap = pImage->DecodeN(fullname, BITMAP_PIXEL_FORMAT_RGB565);

}

else if(fullname.EndsWith(L"bmp"))

{

pBitmap = pImage->DecodeN(fullname, BITMAP_PIXEL_FORMAT_RGB565);

}

else if(fullname.EndsWith(L"png"))

{

pBitmap = pImage->DecodeN(fullname, BITMAP_PIXEL_FORMAT_ARGB8888);

}

else if (fullname.EndsWith(L"gif"))

{

pBitmap = pImage->DecodeN(fullname, BITMAP_PIXEL_FORMAT_RGB565);

}

delete pImage;

return pBitmap;

}

2.Button

我设置了button的背景图片，例子如下

Osp::Graphics::Bitmap *__pReturn;

Osp::Graphics::Bitmap *__pReturnAct;

static const int ID_BUTTON_RETURN = 100;

__pReturn = GetBitmapN(L"return.png");

__pReturnAct = GetBitmapN(L"returnact.png");

Button *pBtnReturn = new Button();

pBtnReturn->Construct(Rectangle(x, y, w, h), "");

pBtnReturn->SetActionId(ID_BUTTON_RETURN);

pBtnReturn->SetNormalBackgroundBitmap(*__pReturn);

pBtnReturn->SetPressedBackgroundBitmap(*__pReturnAct);

pBtnReturn->AddActionEventListener(*this);

AddControl(*pBtnReturn);

delete __pReturn;

delete __pReturnAct;

3.EditField

Osp::Ui::Controls::EditField* __pAddrEdit;

__pAddrEdit = new EditField();

//第二个参数可以根据文本的不同来选择，文本的最大长度可以自定义

__pAddrEdit->Construct(Rectangle(x, y, w, h), EDIT_FIELD_STYLE_URL_SMALL, INPUT_STYLE_FULLSCREEN, false, 300);

AddControl(*__pAddrEdit);

__pAddrEdit->SetEnabled(true);

__pAddrEdit->SetKeypadEnabled(true);

__pAddrEdit->SetText (L"http://");

4.CheckButton

CheckButton *pCheckBtn = new CheckButton();

pCheckBtn->Construct(Rectangle(x, y, dx, dy),CHECK_BUTTON_STYLE_MARK, BACKGROUND_STYLE_NONE, false, "");

pCheckBtn->SetActionId(ID_CHECK_BTN_ON, ID_CHECK_BTN_OFF);

pCheckBtn->SetTextHorizontalAlignment(ALIGNMENT_LEFT); pCheck3G->AddActionEventListener(*this); AddControl(*pCheckBtn);

5.RadioGroup

CheckButton *pCheckWap = new CheckButton();

pCheckWap->Construct(Rectangle(x, y, w, h), CHECK_BUTTON_STYLE_RADIO, BACKGROUND_STYLE_NONE, false, L"wap");

pCheckWap->SetActionId(ID_BUTTON_RADIOWAP_ON, ID_BUTTON_RADIOWAP_OFF);

pCheckWap->AddActionEventListener(*this);

AddControl(*pCheckWap);

CheckButton *pCheckNet = new CheckButton();

pCheckNet->Construct(Rectangle(x, y, w, h),CHECK_BUTTON_STYLE_RADIO, BACKGROUND_STYLE_NONE, false, L"net");

pCheckNet->SetActionId(ID_BUTTON_RADIONET_ON, ID_BUTTON_RADIONET_OFF);

pCheckNet->AddActionEventListener(*this);

AddControl(*pCheckNet);

RadioGroup *pRadioGroup = new RadioGroup();

pRadioGroup->Construct();

pRadioGroup->Add(*pCheckWap);

pRadioGroup->Add(*pCheckNet);

pRadioGroup->SetSelectedItem(*pCheckNet);

AddControl(*pRadioGroup);
