我要将手机通讯录导入应用程序，一旦用户点击按钮，手机联系人列表就会显示出来，一旦用户点击其中一个联系人，就会选择联系人，号码将会显示在textview上显示。但是，当我点击联系人时，发生了错误

java.lang.RuntimeException：传递结果失败 ResultInfo {who = null，request = 1，result = -1，data = Intent { DAT =含量：//com.android.contacts/contacts/lookup/0r1-3F4927292B/1 flg = 0x1}}到活动 {com.example.importcontacts / com.example.importcontacts.ImportContactsActivity}： java.lang.SecurityException：Permission Denial：reading com.android.providers.contacts.ContactsProvider2 uri content：//com.android.contacts/contacts from pid = 609，uid = 10053 需要android.permission.READ_CONTACTS

请告诉我编码，谢谢

Answer 1

好像忘了在清单文件中添加READ_CONTACTS权限

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

如何检索所选联系人中的号码？
