手机联系人的读取

实现步骤

① 获取内容解析者

ContentResolver resolver = getContentResolver();

② 创建Uri

Uri raw_contacts = Uri.parse("content://com.android.contacts/raw_contacts"); Uri data = Uri.parse("content://com.android.contacts/data");

③ 先查询raw_contents表中的content_id

Cursor cursor = resolver.query(raw_contacts, new String[]{"contact_id"}, null, null, null);

④ 遍历其中的内容

while (cursor.moveToNext()){ String id = cursor.getString(0); Contat contat = new Contat(); Log.e(TAG,id); Cursor cursor1 = resolver.query(data, new String[]{"data1", "mimetype"}, "raw_contact_id=?", new String[]{id}, null); while (cursor1.moveToNext()){ String data1 = cursor1.getString(0); String mimetype = cursor1.getString(1); Log.e(TAG,data1+"********"+mimetype); if ("vnd.android.cursor.item/name".equals(mimetype)){ contat.name = data1; }else if ("vnd.android.cursor.item/phone_v2".equals(mimetype)){ contat.phone = data1; }else if ("vnd.android.cursor.item/email_v2".equals(mimetype)){ contat.email = data1; }else if ("vnd.android.cursor.item/postal-address_v2".equals(mimetype)){ contat.address = data1; } contats.add(contat); } }

⑤ 将存在集合中的内容便利出来

//所有内容都保存在了集合中 for(Contat contat:contats){ Log.e("contat",contat.toString()); }

注意: 在读取联系人的时候需要权限

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

手机联系人的插入

实现步骤

① 获取用户的输入

et_name = (EditText) findViewById(R.id.et_name); et_tel = (EditText) findViewById(R.id.et_tel); et_address = (EditText) findViewById(R.id.et_address); et_email = (EditText) findViewById(R.id.et_email); String address = et_address.getText().toString().trim(); String name = et_name.getText().toString().trim(); String tel = et_tel.getText().toString().trim(); String email = et_email.getText().toString().trim();

② 获取内容解析者

ContentResolver resolver = getContentResolver();

③ 创建查询raw_contacts表的uri

Uri raw_contacts = Uri.parse("content://com.android.contacts/raw_contacts"); Uri data = Uri.parse("content://com.android.contacts/data");

④ 获取已经存在的联系人个数 查询raw_contat表中有多少数据,并获取要插入的ID

Cursor cursor = resolver.query(raw_contacts, new String[]{"contact_id"}, null, null, null); int count = cursor.getCount() + 1;

⑤ 向raw_contact插入数据

ContentValues values = new ContentValues(); values.put("contact_id",count); resolver.insert(raw_contacts,values); //向data中插入数据raw_contat_id是一样的 ContentValues values1 = new ContentValues(); //插入地址数据 values1.put("raw_contact_id",count); values1.put("data1",address); values1.put("mimetype","vnd.android.cursor.item/postal-address_v2"); resolver.insert(data,values1); //插入姓名数据 values1.put("data1",name); values1.put("mimetype","vnd.android.cursor.item/name"); resolver.insert(data,values1); //插入电话数据 values1.put("data1",tel); values1.put("mimetype","vnd.android.cursor.item/phone_v2"); resolver.insert(data,values1); //插入邮箱数据 values1.put("data1",email); values1.put("mimetype","vnd.android.cursor.item/email_v2"); resolver.insert(data,values1);

注意: 读取和插入手机联系人信息,需要获取权限

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