我有一个ListView
可以BaseAdapter
有很多不同的inflated
views
。我正在实现用户可以在应用程序中选择的树主题。一切都很好,直到我需要根据用户选择的主题更改行TextView
的外观。ListView
我有一个解决方案,我正在像这样进行动态测试:
@Override
public View getView(int position, View convertView, ViewGroup parent) {
int type = getItemViewType(position);
ViewHolder viewHolder = null;
if (convertView == null) {
switch (type) {
case TYPE_ACTIVE: // inflate active accounts
if (theme == SettingsManager.InterfaceTheme.light)
convertView = inflator.inflate(R.layout.a_login_roaster_light, null);
else if (theme == SettingsManager.InterfaceTheme.dark)
convertView = inflator.inflate(R.layout.a_login_roaster_dark, null);
else
convertView = inflator.inflate(R.layout.a_login_roaster_def, null);
viewHolder = new ViewHolder();
viewHolder.text1 = (TextView) convertView.findViewById(R.id.txt_row1);
viewHolder.text2 = (TextView) convertView.findViewById(R.id.txt_row2);
如您所见,我通过增加任何行布局来更改外观。这是可行的,但有没有更好的方法来做到这一点,因为布局相同,只有颜色或字体大小必须改变?我正在使用 android-support-v7-appcompat.jar 并将我的应用程序清单中的 Theme.AppCompat.Light 主题作为默认主题。我用这个很棒的工具制作了一些主题,Android Action Bar Style Generator
这是使用Android 操作栏样式生成器创建的样式,我发布了一种树样式,因为它们是相同的。这是位于 res\values 中的“轻量级”版本文件
