我正在开发一款游戏，我想设置游戏的布局，使其可以在多个设备屏幕上运行。因此，asset's folder我没有从drawable folder. 因此，稍后我可以根据设备的屏幕获取图像。

更新：

我试过用

mFaceTextureRegionLifeLine = (TiledTextureRegion) TextureRegionFactory.createFromResource(mTextureLifeLine, this, R.drawable.icon, 100, 100);

而且，它在以下错误中解雇了我-

所以，如果可能的话，请告诉我。谢谢，苏里萨哈尼。

这是将为您执行此操作的方法：

public static TextureRegion createFromResource(final Texture pTexture, final Context pContext, final int pDrawableResourceID, final int pTexturePositionX, final int pTexturePositionY)

如果您需要创建平铺纹理区域，请使用以下命令：

public static TiledTextureRegion createTiledFromResource(final Texture pTexture, final Context pContext, final int pDrawableResourceID, final int pTexturePositionX, final int pTexturePositionY, final int pTileColumns, final int pTileRows)

希望这可以帮助。

如果您只是指定drawble id（例如R.drawable.icon），那么根据您的设备，它将从/res/最适合设备的文件夹中提取它：

IE，

/res/drawable/icon.png 
/res/drawable-large/icon.png

这意味着大型设备使用了第二个 png。

有关支持多屏幕的更多信息，请参阅 android 站点。

如果你想从 drawable 文件夹中获取图像，你应该试试这个 ->

Context ctx = getApplicationContext();
Resources r = ctx.getResources();
Drawable d = r.getDrawable(R.drawable.image_name);
