非活动类中的 getResources
我一直在尝试在非活动类中加载位图，但到目前为止我所做的一切都失败了。我什至尝试发送上下文作为参考，但这也会导致错误。
我目前的情况是这样的：
// Surface class
public class GameScreen extends SurfaceView implements Callback {
TileSet ts;
public GameScreen(Context context, AttributeSet attr) {
// Here I send context as a reference
ts = new TileSet(context, R.drawable.tiles);
}
}
// This is the class I need to get resources
public class TileSet {
public TileSet(Context context, int id) {
Bitmap bmp = BitmapFactory.decodeResource(context.getResources(), id);
}
}
有什么想法吗？
I've been trying to load a bitmap in a non-activity class but everything I've done so far has failed. I have even tried to send the Context as reference, but this also results in error.
My current situation looks like this:
// Surface class
public class GameScreen extends SurfaceView implements Callback {
TileSet ts;
public GameScreen(Context context, AttributeSet attr) {
// Here I send context as a reference
ts = new TileSet(context, R.drawable.tiles);
}
}
// This is the class I need to get resources
public class TileSet {
public TileSet(Context context, int id) {
Bitmap bmp = BitmapFactory.decodeResource(context.getResources(), id);
}
}
Any ideas?

您是否尝试过在 Activity 中获取位图，然后将其传递给 GameScreen 的构造函数？
Have you tried just getting the bitmap in the Activity and then passing that to the constructor of your GameScreen?
