通讯录添加新纪录

RROR/AndroidRuntime(4522): Caused by: java.lang.NullPointerException


ERROR/AndroidRuntime(4522):     at android.content.ContextWrapper.getContentResolver(ContextWrapper.java:90)



这表示，要在activity里面直接调用



如果还不行，那就查看权限，我测试代码如下，android2.3.3

ContentValues values = new ContentValues();  

Uri rawContactUri = getContentResolver().insert(RawContacts.CONTENT_URI, values);  

long rawContactId = ContentUris.parseId(rawContactUri);  

  
values.clear();  

values.put(Data.RAW_CONTACT_ID, rawContactId);  

values.put(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE);  

values.put(StructuredName.GIVEN_NAME, "Sullivan");  

values.put(StructuredName.FAMILY_NAME, "Mike");  

getContentResolver().insert(Data.CONTENT_URI, values);  

  

values.clear();  

values.put(Data.RAW_CONTACT_ID, rawContactId);  
values.put(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE);  

values.put(Phone.NUMBER, "13989297343");  

values.put(Phone.TYPE, Phone.TYPE_HOME);  

values.put(Email.DATA, "[email protected]");  

values.put(Email.TYPE, Email.TYPE_WORK);  

getContentResolver().insert(Data.CONTENT_URI, values);
