我正在处理可扩展列表视图。我需要根据我的数据库值在childview（child_row）的imageview中显示不同的图像。我试图设置图像，但没有任何作品。可扩展列表视图的自定义childrow
对此有何帮助？在此先感谢....
ExpandableListActivity.java
public class ExpList extends ExpandableListActivity
{
String parent_node[];
String custom_child[][][][];
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle icicle)
{
super.onCreate(icicle);
setContentView(R.layout.main);
SimpleExpandableListAdapterWithEmptyGroups expListAdapter =
new SimpleExpandableListAdapterWithEmptyGroups(
this,
createGroupList(),
R.layout.group_row,
new String[] { "colorName" },
new int[] { R.id.groupname },
createChildList2(),
R.layout.child_row,
new String[] { "name", "number", "date", "time"},
new int[] { R.id.name, R.id.number,R.id.date, R.id.time}
);
setListAdapter(expListAdapter);
// I tried all following methods to put different image in imageview, but not working.
LayoutInflater inflater = (LayoutInflater)this.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.child_row, null);
ImageView img_call = (ImageView)layout.findViewById(R.id.img_call_icon);
img_call.setBackgroundResource(R.drawable.skype);
Drawable d = getResources().getDrawable(R.drawable.skype);
img_call.setBackgroundDrawable(d);
img_call.setImageResource(R.drawable.skype);
img_call.setImageDrawable(d);
}
}
