Android 简单联系人操作

Android中的Contacts联系人通过ContentProvider对外提供联系人数据及操作接口。

下面通过简单例子，来看看有关联系人的基本操作。

    public class MainActivity extends ListActivity {            private ArrayList<String> list = new ArrayList<String>();            private ArrayAdapter adapter;            /** Called when the activity is first created. */            @Override            public void onCreate(Bundle savedInstanceState) {                super.onCreate(savedInstanceState);                insert();                queryByName();                queryAll();                adapter = new ArrayAdapter(this,R.layout.main,list);                this.setListAdapter(adapter);            }            //查询所有联系人              public void queryAll() {                  ContentResolver resolver = this.getContentResolver();
