读取联系人

安卓可以通过contentResolver来读取联系人表，联系人表的Uri信息是：content://com.android.contacts/data/phones 从而输出联系人信息，

需要相关权限：

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

具体代码如下：

    //需要读联系人权限READ_CONTACTS@SuppressLint("Range")private fun getContact() {//查询raw_contacts表获得联系人val resolver = contentResolverval uri = Uri.parse("content://com.android.contacts/data/phones")//查询联系人val cursor = resolver.query(uri, null, null, null, null)while (cursor!!.moveToNext()) {val name =cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME))val number =cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))Log.d(TAG, "联系人:${name}")Log.d(TAG, "电话:${number}")}cursor.close()}

输出结构如下：

//2023-08-06 17:29:50.535 31719-31719 MainActivity2           com.example.myapplication            D  联系人:张三
//2023-08-06 17:29:50.535 31719-31719 MainActivity2           com.example.myapplication            D  电话:1 (883) 22
//2023-08-06 17:29:50.535 31719-31719 MainActivity2           com.example.myapplication            D  联系人:si li
//2023-08-06 17:29:50.535 31719-31719 MainActivity2           com.example.myapplication            D  电话:10020
//2023-08-06 17:29:50.535 31719-31719 MainActivity2           com.example.myapplication            D  联系人:bo xiao
//2023-08-06 17:29:50.535 31719-31719 MainActivity2           com.example.myapplication            D  电话:10086

添加联系人

同理，使用contentResolver。需要写联系人权限

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

具体代码如下：

    private fun insertContact() {val resolver = contentResolverval values = ContentValues()//向raw_contacts表插入空数据,拿到urival uri = resolver.insert(ContactsContract.RawContacts.CONTENT_URI,values)//拿到表idval id = uri?.let { ContentUris.parseId(it) }//插入姓名values.clear()//put idvalues.put(ContactsContract.Data.RAW_CONTACT_ID,id)//put typevalues.put(ContactsContract.Data.MIMETYPE,StructuredName.CONTENT_ITEM_TYPE)//put 值values.put(StructuredName.GIVEN_NAME,"xiaohong")resolver.insert(ContactsContract.Data.CONTENT_URI,values)//插入手机号values.clear()//put idvalues.put(ContactsContract.Data.RAW_CONTACT_ID,id)//put typevalues.put(ContactsContract.Data.MIMETYPE,Phone.CONTENT_ITEM_TYPE)//put 值values.put(Phone.NUMBER,"15541383234")values.put(Phone.TYPE,Phone.TYPE_MOBILE)resolver.insert(ContactsContract.Data.CONTENT_URI,values)//插入邮箱values.clear()//put idvalues.put(ContactsContract.Data.RAW_CONTACT_ID,id)//put typevalues.put(ContactsContract.Data.MIMETYPE,Email.CONTENT_ITEM_TYPE)//put 值values.put(Email.DATA,"163@qq.com")values.put(Email.TYPE,Email.TYPE_WORK)resolver.insert(ContactsContract.Data.CONTENT_URI,values)}

运行结果如下：

更新联系人

这里我们是根据手机号码先获取联系人表id，也仅有这种方式，获取id

    @SuppressLint("Range")private fun getContactByPhone(phone: Long): String? {val resolver = contentResolverval uri = Uri.parse("content://com.android.contacts/data/phones/filter/$phone")val cursor= resolver.query(uri, arrayOf(ContactsContract.Data.CONTACT_ID),null,null,null)return if (cursor!!.moveToNext()){val id = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.CONTACT_ID))cursor.close()id}else{null}}

拿到ContactId后，去更新数据

    //根据手机号更新@SuppressLint("SuspiciousIndentation")private fun updateContact() {val id  = getContactByPhone(15541383234)if(id!=null){val values = ContentValues()val resolver = contentResolvervalues.put(ContactsContract.Data.MIMETYPE,CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE)values.put(CommonDataKinds.StructuredName.GIVEN_NAME,"xiaohong_update")resolver.update(ContactsContract.Data.CONTENT_URI, values,"${ContactsContract.Data.CONTACT_ID}=?",arrayOf(id))}}

删除联系人

删除联系人，比较简单，我们可以通过联系人名字，删除

    private fun deteleContact() {val resolver = contentResolver//根据联系人删除val ret = resolver.delete(RawContacts.CONTENT_URI, CommonDataKinds.Phone.DISPLAY_NAME+"=?",arrayOf("si li"))if(ret > 0){Toast.makeText(this, "删除成功", Toast.LENGTH_LONG).show()}}

也可以根据联系人手机号删除，具体代码如下：

    private fun deteleContact() {val resolver = contentResolver//根据手机号删除val id = getContactByPhone(10020)val ret = resolver.delete(RawContacts.CONTENT_URI, CommonDataKinds.Phone.CONTACT_ID+"=?",arrayOf(id))if(ret > 0){Toast.makeText(this, "删除成功", Toast.LENGTH_LONG).show()}}

读取短信

除此，我们还可以通过contentResolver读取短信信息，短信表的uri信息content://sms/

用途比如验证码快捷输入，像ios短信验证码快速copy到输入框。

下面看看任何实现

第一，读取短信信息，需要权限：

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

具体代码如下；

    private fun getMsgs() {val uri = Uri.parse("content://sms/")val resolver = contentResolverval  cursor =resolver.query(uri, arrayOf("address","date","type","body"),null,null,null)while (cursor!!.moveToNext()){val  address = cursor.getString(0)val  date = cursor.getString(1)val  type = cursor.getString(2)val  body = cursor.getString(3)Log.d(TAG,"address:${address},date:${date},type:${type},body:${body}")}cursor.close()}

下面是一些表的uri信息：
