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 @Override public 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 @Override protected 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(); } } }
