android 跳转到系统通讯录

跳转到系统的通信录列表，并读取联系人电话

需要权限

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

6.0之后需要动态申请权限

int readStoragePermission = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_CONTACTS);

if (readStoragePermission != PackageManager.PERMISSION_GRANTED) {    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_CONTACTS}, REQUEST_READ_CONTACT);} else {    Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);    startActivityForResult(intent, GET_CONTACT);

}

//请求权限回调

@Overridepublic void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {    switch (requestCode) {        case REQUEST_READ_CONTACT://读取手机联系人权限            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {                // Permission Granted
Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);    startActivityForResult(intent, GET_CONTACT);            } else {                // Permission Denied            }            break;    }    super.onRequestPermissionsResult(requestCode, permissions, grantResults);}

//获取点击选中的联系人回调

@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {
    case GET_CONTACT: 
if (resultCode == RESULT_OK) {
     Uri uri = data.getData();
     getPhone(uri);
}
         break;
   
}
private void getPhone(Uri uri) {        if (uri != null) {            Cursor c = getContentResolver().query(uri, null, null, null, null);            if (c == null) {                return;            }            if (c.moveToFirst()) {                String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));                String hasPhone = c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));                String contactId = c.getString(c.getColumnIndex(ContactsContract.Contacts._ID));                if ("1".equalsIgnoreCase(hasPhone)) {//判断是否含有手机号                    Cursor phoneCursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,                            null,                            ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = "                                    + contactId,                            null,                            null);                    while (phoneCursor.moveToNext()) {//循环该联系人下所有电话号码                        String phone = phoneCursor.getString(phoneCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));//                        String name = phoneCursor.getString(phoneCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));                    }                    phoneCursor.close();                } else {                    Toast.makeText(this,"联系人手机号码不能为空",Toast.LENGTH_SHORT).show();                }                c.close();            }        }    }
