android求教，急

Question

public long addPhone(String name,String number){
// TODO Auto-generated method stub
ContentValues values=new ContentValues();
Uri rawContactUri=getContentResolver().insert(RawContacts.CONTENT_URI, values);
long rawContactId=ContentUris.parseId(rawContactUri);
                   .....
return rawContactId;

}
为什么提示Uri rawContactUri=getContentResolver().insert(RawContacts.CONTENT_URI, values);有错

Answer 1

运行时错误还是编译就错了，log

Answer 2

将
Uri rawContactUri=getContentResolver().insert(RawContacts.CONTENT_URI, values);
改为
Uri rawContactUri = this.getContext().getContentResolver().insert(RawContacts.CONTENT_URI, values);
或者改为
Uri rawContactUri = this.getBaseContext().getContentResolver().insert(RawContacts.CONTENT_URI, values);

Answer 3

楼主确认当前的类是Context的子类？有getContentResolver()这个方法？

Answer 4

改了，不对

Answer 5

所有代码：
public class AddPhone extends Activity { public long addPhone(String name,String number){
// TODO Auto-generated method stub
ContentValues values=new ContentValues();
Uri rawContactUri= this.getBaseContext().getContentResolver().insert(RawContacts.CONTENT_URI, values);
Log.i("ddd", name);
long rawContactId=ContentUris.parseId(rawContactUri);


if(name!=""){
values.clear();
values.put(Data.RAW_CONTACT_ID, rawContactId);
values.put(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE);
values.put(StructuredName.GIVEN_NAME, name);
getContentResolver().insert(ContactsContract.Data.CONTENT_URI, values);

}
if(number!=""){
values.clear();
values.put(Data.RAW_CONTACT_ID, rawContactId);
values.put(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE);
values.put(Phone.NUMBER, number);
values.put(Phone.TYPE, Phone.TYPE_MOBILE);
getContentResolver().insert(ContactsContract.Data.CONTENT_URI, values);
}
return rawContactId;

}}
哪位大侠会，帮帮忙，感激呀！！！

Answer 6

是空指针，那句话里某个引用指向null了应该是values这个，你调用values.put()方向在ContentValues values=new ContentValues();
这句话后面写入一条数据线

Answer 7

空了．　ContentValues包裹你的数据．就相当于把你的数据对象克隆给它封装到ContentValues．
你的ContentValues中没有数据为空
