Andoroid 保存联系人到系统通讯录

先添加权限
AndoridManifest.xml

<uses-permission android:name="android.permission.WRITE_CONTACTS"></uses-permission>
    <uses-permission android:name="android.permission.READ_CONTACTS"></uses-permission>

代码中

if (Build.VERSION.SDK_INT >= 23) {
            int REQUEST_CODE_CONTACT = 101;
            String[] permissions = {Manifest.permission.WRITE_CONTACTS, Manifest.permission.READ_CONTACTS};
            //验证是否许可权限
            for (String str : permissions) {
                if (MyApplication.getContext().checkSelfPermission(str) != PackageManager.PERMISSION_GRANTED) {
                    //申请权限
                    this.requestPermissions(permissions, REQUEST_CODE_CONTACT);
                }
            }
