我知道这是不是这个话题复选框和列表视图的第一个问题，但我不知道该怎么办..CheckedTextView ListView的页眉 - 排序
我有CheckedTextView和TextView的，如果一个ListView我滚动一些其他的将得到遏制...... 的观点得到使出太和启用/禁用部分（带有SharedPref）也不起作用......

Android ListView Headers
所以有我的代码：
ActivtyMain.java
public class ActivityMain extends NavigationDrawerActivity{
@Override
public void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.activity_main);
super.onCreate(savedInstanceState);
context=this;
this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
character_header_id.add(0);
character_header_id.add(character_original.size()+1);
character_header_id.add(character_original.size()+character_extension1.size()+2);
character_header_id.add(character_original.size()+character_extension1.size()+character_extension2.size()+3);
items.add(new CharacterHeader(getString(R.string.character_original)));
for(character key:character_original) {
String value=character_translation.get(key);
//System.out.println(value);
items.add(new CharacterListItem(value));
}
items.add(new CharacterHeader(getString(R.string.character_extension1)));
for(character key:character_extension1) {
String value=character_translation.get(key);
items.add(new CharacterListItem(value));
}
items.add(new CharacterHeader(getString(R.string.character_extension2)));

}
