用ContentProvider向系统增加联系人

发现对系统的联系人进行操作的api很乱，感觉逻辑有点不清楚......

主要用到这4个类：

android.provider.ContactsContract.CommonDataKinds.Email;
android.provider.ContactsContract.CommonDataKinds.Phone;
android.provider.ContactsContract.CommonDataKinds.StructuredName;
android.provider.ContactsContract.Data;

 import android.content.ContentResolver;
 import android.content.ContentUris;
 import android.content.ContentValues;
 import android.net.Uri;
 import android.os.Bundle;
 import android.provider.ContactsContract.CommonDataKinds.Email;
 import android.provider.ContactsContract.CommonDataKinds.Phone;
 import android.provider.ContactsContract.CommonDataKinds.StructuredName;
 import android.provider.ContactsContract.Data;
 import android.provider.ContactsContract.RawContacts;
 import android.support.v7.app.ActionBarActivity;
 import android.util.Log;
 import android.view.Menu;
 import android.view.MenuItem;
 import android.view.View;
 import android.widget.Button;
 import android.widget.EditText;

 public class MainActivity extends ActionBarActivity {
     ContentResolver contentResolver;
     EditText name;
     EditText phone;
     EditText emil;

     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
         name = (EditText) findViewById(R.id.editText_name);
         phone = (EditText) findViewById(R.id.EditText_phone);
         emil = (EditText) findViewById(R.id.editText_emil);
         contentResolver = getContentResolver();
         Button saveButton = (Button) findViewById(R.id.button_insert);
         saveButton.setOnClickListener(new MyOnclickListener());

     }

     class MyOnclickListener implements View.OnClickListener {

         @Override
         public void onClick(View v) {
             ContentValues values = new ContentValues();
             Uri rawContactUri = contentResolver.insert(RawContacts.CONTENT_URI, values);//插入一个空值，目的是增加一条记录，返回该记录的id
             long rawContactId = ContentUris.parseId(rawContactUri);
             Log.i("csx", "rawContactId:" + rawContactId);
             // 插入姓名
             values.clear();
             values.put(Data.RAW_CONTACT_ID, rawContactId);
             values.put(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE);
             values.put(StructuredName.GIVEN_NAME, name.getText().toString());
             contentResolver.insert(Data.CONTENT_URI, values);
             // 插入电话
             values.clear();
             values.put(Data.RAW_CONTACT_ID, rawContactId);
             values.put(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE);
             values.put(Phone.NUMBER, phone.getText().toString());
             values.put(Phone.TYPE, Phone.TYPE_MOBILE);
             contentResolver.insert(Data.CONTENT_URI, values);
             // 插入邮箱
             values.clear();
             values.put(Data.RAW_CONTACT_ID, rawContactId);
             values.put(Data.MIMETYPE, Email.CONTENT_ITEM_TYPE);
             values.put(Email.DATA, emil.getText().toString());
             values.put(Email.TYPE, Email.TYPE_WORK);
             contentResolver.insert(Data.CONTENT_URI, values);

         }
     }
