第四十九篇 -- 添加联系人信息Addcontact

往通讯录里添加联系人

首先，在清单文件里添加读写权限

    <uses-permission android:name="android.permission.READ_CONTACTS"/><!-- 读取通讯录权限 -->
    <uses-permission android:name="android.permission.WRITE_CONTACTS"/><!-- 写入通讯录权限 -->

import android.widget.EditText;
import android.widget.Toast;

        setContentView(R.layout.activity_main);
        performCodeWithPermission("插入联系人信息", new PermissionCallback() {

            }
        }, Manifest.permission.WRITE_CONTACTS, Manifest.permission.READ_CONTACTS);

        mEtname = findViewById(R.id.et_name);
        mEtmail = findViewById(R.id.et_email);
        mEtphone = (EditText) findViewById(R.id.et_phone);

        int new_id = cursor.getCount() + 1;

        ContentValues values = new ContentValues();
        resolver.insert(uri,values);

        //3.在data表里面添加联系人数据
        ContentValues namevalues = new ContentValues();
        namevalues.put("raw_contact_id",new_id);
        namevalues.put("data1",name);
