我想只将我的子文本的某些部分(在我的ExpandableListview中)更改为不同的颜色和/或字体。
示例:
你好,世界! (我只想以粗体显示你好)
如果可以,请有人分享。
ExpandableListadapter:
public class ExpandListAdapter extends BaseExpandableListAdapter {
private Context context;
private ArrayList<Group> groups;
public ExpandListAdapter(Context context, ArrayList<Group> groups) {
this.context = context;
this.groups = groups;
}
@Override
public Object getChild(int groupPosition, int childPosition) {
ArrayList<Child> chList = groups.get(groupPosition).getItems();
return chList.get(childPosition);
}
@Override
public long getChildId(int groupPosition, int childPosition) {
return childPosition;
}
@Override
public View getChildView(int groupPosition, int childPosition,
boolean isLastChild, View convertView, ViewGroup parent) {
Child child = (Child) getChild(groupPosition, childPosition);
if (convertView == null) {
LayoutInflater infalInflater = (LayoutInflater) context
.getSystemService(context.LAYOUT_INFLATER_SERVICE);
convertView = infalInflater.inflate(R.layout.child_item, null);
}
TextView tv = (TextView) convertView.findViewById(R.id.country_name);
ImageView iv = (ImageView) convertView.findViewById(R.id.flag);
tv.setText(child.getName().toString());
iv.setImageResource(child.getImage());
return convertView;
}
@Override
public int getChildrenCount(int groupPosition) {
ArrayList<Child> chList = groups.get(groupPosition).getItems();
return chList.size();
}
@Override
public Object getGroup(int groupPosition) {
return groups.get(groupPosition);
}
@Override
public int getGroupCount() {
return groups.size();
}
@Override
public long getGroupId(int groupPosition) {
return groupPosition;
}
@Override
public View getGroupView(int groupPosition, boolean isExpanded,
View convertView, ViewGroup parent) {
Group group = (Group) getGroup(groupPosition);
if (convertView == null) {
LayoutInflater inf = (LayoutInflater) context
.getSystemService(context.LAYOUT_INFLATER_SERVICE);
convertView = inf.inflate(R.layout.group_item, null);
}
TextView tv = (TextView) convertView.findViewById(R.id.group_name);
tv.setText(group.getName());
return convertView;
}
@Override
public boolean hasStableIds() {
return true;
}
@Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
return true;
}
}

在没有将文本分成单独的TextViews的情况下,我不知道有任何理智的方法。
您可以拆分传入的字符串child.getName().toString().split(",")
(请参阅Split documentation)并使用生成的数组填充单独的TextView,每个TextView具有不同的样式。
例如,在您现有的getChildView
:
TextView tv1 = (TextView) convertView.findViewById(R.id.country_name_1);
TextView tv2 = (TextView) convertView.findViewById(R.id.country_name_2);
String[] splitString = child.getName().toString().split(",");
tv1.setText(splitString[0]);
tv2.setText(splitString[1]);
你当然会添加一些错误检查,但这取决于你(确保child.getName()不是null,splitString至少是长度2所以你没有得到一个索引出界限异常等。)。

我决定为粗体textview创建一个setter和getter,然后我将其连接到Expandablelistview的数组列表。它可能不是最有效的方式,但它解决了我的问题。
