如何给ListView的每一行使用不同的背景图片？

[Featured]

注意：是背景图片；不是icon图片。

另外，我实际需要使用的是ExpandableListview，不过这两者应该差不多的吧。

使用adapter时,用map指定多个control和对应的资源drawable, text etc

楼上说的有点笼统。有没有多一点的解释？？

[Quote=引用 4 楼 feifanup 的回复:]
ArrayList<HashMap<String, Object>> m_data = new ArrayList<HashMap<String, Object>>();

for xxx

HashMap<String, Object> map = new HashMap<String, Object>();
map.put("background", R.id.drawableBG……

兄弟，我试了这些代码；似乎并不能真正修改背景图片哎。

应该是需要xml文件的吧。真正实现背景绘制的是在xml文件里面。你能不能把xml文件或者整个工程贴上来？多谢了

[feifanup]

ArrayList<HashMap<String, Object>> m_data = new ArrayList<HashMap<String, Object>>();

for xxx
{
HashMap<String, Object> map = new HashMap<String, Object>();
map.put("background", R.id.drawableBGXXX);
map.put("text", R.id.stringXXXXX);
m_data.add(map);
}
SimpleAdapter m_adapter= new SimpleAdapter(窗口句柄
,m_data //data source
,R.layout.XXX
,new String[]{"background", "text"}
,new int[]{R.id.CONTROLTOSETBACKGROUND, R.id.CONTROLTEXTVIEW});

派生自己的Adapter，在GetView中根据Position，利用ImageView加载图片并与你的其他内容组合成一个view或viewGroup或Layout返回，即可。

如果你item很多的话 那肯定是很占用内存的吧

这样是可以实现的

[gujinf2008]

说的都差不多，楼主网上搜搜例子应该可以解决了。

重写Adapter类，实现自定义的list item

谢谢大家，我来试一下。不过，如我上面所说，我真正想实现的是ExpandableListview上面定制背景图片，不知道它的话有什么不同？

[小裴同学]

自定义adapter

public View getView(int position, View convertView, ViewGroup parent) {
View myView = inflater.inflate(R.layout.XXX, null);

if(position==1){
myView.setBackgroundDrawable(R.id.XXX);
}
if(osition==2){
myView.setBackgroundDrawable(R.id.XXX);
}

}

看不懂啊 怎么和ListView感觉差那么多呢
