Question

怎么获取drawable对象呀

public class MyImageGetter implements ImageGetter{ public Drawable getDrawable(String source) { // TODO Auto-generated method stub Drawable drawable = getResources().getDrawable(R.drawable.smileyface); return drawable; } }想实现ImageGetter接口，发现在这里没有getResources()的方法从资源获得drawable对象，应该怎么获得呀？

Answer 1

source值为你那个R.drawable.XX，也就是int，然后你就可以直接getResources().getDrawable(source)了

Answer 2

获取本地的？还是网络的？[mw_shl_code=java,true] String url1 = "这里写你的SD卡目录的那个地址";Drawable drawable = getDrawable(url1); imgBtn.setImageDrawable(drawable);public Drawable getDrawable(String source) { // TODO Auto-generated method stub try { InputStream is = (InputStream) new URL(url).getContent(); Drawable d = Drawable.createFromStream(is, "src"); return d; } catch (Exception e) { return null; } return drawable; }[/mw_shl_code]

Answer 3

通过构造方法吧Context对象实例传进来，通过context.getR···就可以了！

Answer 4

int id = Integer.parseInt(source); Drawable d = getResources().getDrawable(id);
