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);

        }
    }
