Android load drawable images

vishalhsoni · August 29, 2012, 6:07am

Is it possible to load images run-time from drawable-hdpi or drawable-mdpi depending upon device density?

I have searched a lot but could not find the solution.

I’m not entirely sure, actually. I found a few things: https://stackoverflow.com/questions/20071887/what-is-the-meaning-of-drawable-hdpi-drawable-ldpi-drawable-mdpi-drawable-xhd

But I think @drelaptop is better to ask.

thanks for the reply and I am aware of those things that’s why I asked that can access that in cocos2dx so we don’t need to worry about resolution when we are creating an app for different resolution phone

do this by set search paths properly.

cpp-empty-test on v3 branch have show the similar case, the Resources dir like:

├── ipad
│   ├── CloseNormal.png
│   ├── CloseSelected.png
│   └── HelloWorld.png
├── ipadhd
│   ├── CloseNormal.png
│   ├── CloseSelected.png
│   └── HelloWorld.png
└── iphone
    ├── CloseNormal.png
    ├── CloseSelected.png
    └── HelloWorld.png

the code is:

// If the frame's height is larger than the height of medium resource size, select large resource.
if (frameSize.height > mediumResource.size.height)
{
    searchPath.push_back(largeResource.directory);


    director->setContentScaleFactor(MIN(largeResource.size.height/designResolutionSize.height, largeResource.size.width/designResolutionSize.width));
}
// If the frame's height is larger than the height of small resource size, select medium resource.
else if (frameSize.height > smallResource.size.height)
{
    searchPath.push_back(mediumResource.directory);
    
    director->setContentScaleFactor(MIN(mediumResource.size.height/designResolutionSize.height, mediumResource.size.width/designResolutionSize.width));
}
// If the frame's height is smaller than the height of medium resource size, select small resource.
else
{
    searchPath.push_back(smallResource.directory);


    director->setContentScaleFactor(MIN(smallResource.size.height/designResolutionSize.height, smallResource.size.width/designResolutionSize.width));
}
