如何更改SimpleExpandableListAdapter文本颜色 [英] how to change text color in SimpleExpandableListAdapter
问题描述
我使用ExpandableListFragment创建TabHost片段内的ExpandableList
i am using ExpandableListFragment to create an ExpandableList inside a TabHost fragment
我得到了code为ExpandableListFragment从这里 https://gist.github.com/1316903一>
i got the code for ExpandableListFragment from here https://gist.github.com/1316903
这似乎做工精细但我无法弄清楚如何改变文字颜色。
it seems to work fine except i cannot figure out how to change the text color.
我的实现看起来像这样
public class LocalListFragment extends ExpandableListFragment {
private static final String NAME = "NAME";
private static final String IS_EVEN = "IS_EVEN";
private ArrayList<String> mGroups;
private ArrayList<ArrayList<Song>> mChildren;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
// Set up our adapter
List<Map<String, String>> groupData = new ArrayList<Map<String, String>>();
List<List<Map<String, String>>> childData = new ArrayList<List<Map<String, String>>>();
for (int i = 0; i < 10; i++) {
Map<String, String> curGroupMap = new HashMap<String, String>();
groupData.add(curGroupMap);
curGroupMap.put(NAME, "GROUP" + i);
//curGroupMap.put(IS_EVEN, (i % 2 == 0) ? "This group is even" : "This group is odd");
List<Map<String, String>> children = new ArrayList<Map<String, String>>();
for (int j = 0; j < 5; j++) {
Map<String, String> curChildMap = new HashMap<String, String>();
children.add(curChildMap);
curChildMap.put(IS_EVEN, "Child " + j);
}
childData.add(children);
}
mAdapter = new SimpleExpandableListAdapter(
getActivity().getApplicationContext(),
groupData,
android.R.layout.simple_expandable_list_item_1,
new String[] { NAME, IS_EVEN },
new int[] { android.R.id.text1, android.R.id.text2 },
childData,
android.R.layout.simple_expandable_list_item_2,
new String[] { NAME, IS_EVEN },
new int[] { android.R.id.text1, android.R.id.text2 }
);
//TextView tv = (TextView)getActivity().findViewById(android.R.id.text1);
//tv.setTextColor(0xffff0000);
setListAdapter(mAdapter);
return super.onCreateView(inflater, container, savedInstanceState);
}
@Override
public void onListItemClick(ListView l, View v, int position, long id) {
Log.i("TAG", "Item selected");
}
}
我的猜测是,该行新INT [] {android.R.id.text1,android.R.id.text2},有很多事情做,但我有点糊涂了这一点。
my guess is that the lines 'new int[] { android.R.id.text1, android.R.id.text2 },' has a lot to do with it but i'm a bit confused about this.
有人可以请帮助?我是否需要创造新的TextView的id,并指定文字颜色?我试过,但不能弄明白。谢谢。
can someone please help? do i need to creat new TextView id's and specify textColor? i tried but couldn't figure it out. thanks.
推荐答案
列表适配器只是orverride getview方式:
just orverride getview method of list adapter :
mAdapter = new SimpleExpandableListAdapter(
getActivity().getApplicationContext(),
groupData,
android.R.layout.simple_expandable_list_item_1,
new String[] { NAME, IS_EVEN },
new int[] { android.R.id.text1, android.R.id.text2 },
childData,
android.R.layout.simple_expandable_list_item_2,
new String[] { NAME, IS_EVEN },
new int[] { android.R.id.text1, android.R.id.text2 }){
@Override
public View getChildView(int groupPosition, int childPosition,
boolean isLastChild, View convertView, ViewGroup parent) {
TextView tv = (TextView) super.getChildView(groupPosition, childPosition, isLastChild,convertView, parent);
//change background of tv here
return tv;
}
@Override
public View getGroupView(int groupPosition, boolean isExpanded,
View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
TextView tv = (TextView) super.getGroupView(groupPosition, isExpanded, convertView, parent);
//change background of tv here
return tv;
}
};
