[英]How to set background image in Tizen native app
I have been trying to set background image in Tizen Native app but have not been successful so far. 我一直在尝试在Tizen本机应用程序中设置背景图像,但到目前为止尚未成功。 I have tried doing the same through Canvas and Bitmap but its not working,though i am not getting any error. 我已经尝试通过Canvas和Bitmap进行相同的操作,但是它没有用,尽管我没有收到任何错误。
I am using the below code in the OnInitializing function of my form. 我在表单的OnInitializing函数中使用以下代码。
AppResource *pAppResource = Application::GetInstance()->GetAppResource();
Bitmap* pBitmap1 = pAppResource->GetBitmapN(L"image.png");
Canvas *pCanvas = new Canvas();
pCanvas->Construct();
pCanvas->DrawBitmap(Point(0,0), *pBitmap1);
pCanvas->Show();
Any idea what could be the issue or any other simpler way of doing the same? 知道这可能是问题所在,还是其他更简单的方法?
Thanks, 谢谢,
从表单中使用GetCanvasN()方法。
use OnDraw to draw the background 使用OnDraw绘制背景
result TizenForm::OnDraw()
{
result r=E_SUCCESS;
Canvas* pCanvas;
if (__pFormBitmap)
{
pCanvas = this->GetCanvasN();
pCanvas->DrawBitmap(Point(0, 0), *__pFormBitmap);
}
delete pCanvas;
return r;
}
Add a folder named "screen-density-xhigh" to the resource folder and store image to this folder that you want to set as application background. 将名为“ screen-density-xhigh”的文件夹添加到资源文件夹,并将图像存储到要设置为应用程序背景的此文件夹。 Now declare result type onDraw() function into the application header.Now implement the code bellow to the .cpp file of this form. 现在在应用程序头文件中声明结果类型onDraw()函数,现在将以下代码实现到此形式的.cpp文件中。
result TizenForm::OnDraw()
{
result r = E_UNKNOWN;
AppResource *pAppResource = Application::GetInstance()->GetAppResource();
Bitmap* pBitmap1 = pAppResource->GetBitmapN(L"backgroundImage.jpg");
Canvas* pCanvas = GetCanvasN();
if (pCanvas != null)
{
pCanvas->DrawBitmap(Rectangle(0, 0,720,1280), *pBitmap1);
}
return r;
}
